Postexercise hydration is fundamental to replace fluid loss from sweat. This study evaluated rehydration and gastrointestinal (GI) symptoms for each of three beverages: water (W), sports drink (SD), and skimmed, lactose-free milk (SLM) after moderate-intensity cycling in the heat. Sixteen college students completed three exercise sessions each to lose ≈2% of their body mass. They drank 150% of body mass loss of the drink assigned in randomized order; net fluid balance, diuresis, and GI symptoms were measured and followed up for 3 hr after completion of fluid intake. SLM showed higher fluid retention (∼69%) versus W (∼40%; p <.001); SD (∼56%) was not different from SLM or W (p >.05). Net fluid balance was higher for SLM (−0.26 kg) and SD (−0.42 kg) than W (−0.67 kg) after 3 hr (p <.001), resulting from a significantly lower diuresis with SLM. Reported GI disturbances were mild and showed no difference among drinks (p >.05) despite ingestion of W (1,992 ± 425 ml), SD (1,999 ± 429 ml), and SLM (1,993 ± 426 ml) in 90 min. In conclusion, SLM was more effective than W for postexercise rehydration, showing greater fluid retention for the 3-hr follow-up and presenting with low-intensity GI symptoms similar to those with W and SD. These results confirm that SLM is an effective option for hydration after exercise in the heat. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the utility of Pulse index Contour Continuous Cardiac Output (PiCCO) monitoring in critically ill patients. Study Design: Cross-sectional study. Setting: Intensive Care Unti of Sindh Institute of Urology and Transplant, Karachi, Pakistan. Period: October 2022 to March 2023. Methods: Patients presenting with various types of shock, requiring high-dose vasopressors or inotropes, and not responding to initial fluid therapy were analyzed. Demographic details, SOFA score, APACHE score, and invasive hemodynamic parameters using the PiCCO system were documented. Results: Out of 142 ICU admissions, 38 patients were included in the study. Most patients were males (73%) with a median age of 39 years. Significant changes were observed in the cardiac index, cardiac performance index, global ejection fraction, and systemic vascular resistance index (SVRI), all with p-values less than 0.05. The interventions included the initiation of inotropes in 22 patients (57.8%), diuretics in 4 patients (10.5%), and intravenous fluids in 19 patients (50%). Additionally, vasopressor doses were adjusted in 18 patients (47.3%). Initially, patients were presumed to have pure septic shock based on CO2 gap, mixed venous saturation, and echocardiographic assessment. However, after applying PiCCO monitoring, the diagnosis was revised to mixed shock in 21 patients (55.2%). Conclusion: PiCCO monitoring appears to be a valuable tool in the ICU for managing patients with complex hemodynamic profiles, facilitating targeted interventions that lead to significant improvements in hemodynamic stability.

Background and Aim: We aimed to evaluate comparative outcomes of aggressive versus non‐aggressive intravenous fluid (IVF) therapy in patients with acute pancreatitis. Methods: A systematic search of electronic data sources and bibliographic reference lists were conducted. All randomized controlled trials (RCTs) reporting outcomes of aggressive versus non‐aggressive IVF therapy in acute pancreatitis were included and their risk of bias were assessed. Effect sizes were determined for overall mortality, systemic inflammatory response syndrome (SIRS), sepsis, respiratory failure, pancreatic necrosis, severe pancreatitis, clinical improvement, AKI, and length of stay using random‐effects modeling. Trial sequential analysis was conducted to determine risk of types 1 or 2 errors. Results: We included 10 RCTs reporting 993 patients with acute pancreatitis who received aggressive (n = 475) or non‐aggressive (n = 518) IVF therapy. Aggressive IVF therapy was associated with significantly higher rate of sepsis (OR: 2.68, P = 0.0005) and longer length of stay (MD: 0.94, P < 0.00001) compared with the non‐aggressive approach. There was no statistically significant difference in mortality (RD: 0.02, P = 0.31), SIRS (OR: 0.93, P = 0.89), respiratory failure (OR: 2.81, P = 0.07), pancreatic necrosis (OR: 1.98, P = 0.06), severe pancreatitis (OR: 1.31, P = 0.38), clinical improvement (OR: 1.12, P = 0.83) or AKI (OR: 1.06, P = 0.91) between the two groups. Sub‐group analysis demonstrated higher morbidity and mortality associated with the aggressive approach in more severe disease. Trial sequential analysis detected risk of type 2 error. Conclusions: Aggressive IVF therapy may be associated with higher morbidity in patients with acute pancreatitis compared with the non‐aggressive approach, particularly in patients with more severe disease. It may also prolong length of hospital stay. The available evidence is subject to type 2 error indicating the need for adequately powered RCTs. [ABSTRACT FROM AUTHOR]

Intestinal ligation during ovariohysterectomy has not been previously reported in dogs. Risk factors for this complication appear to be the same as those for ureteral injury, namely decreased surgical visualization due to small patient size and small incision size. This case report describes how the presentation of intestinal ligation in a 2‐kg, 11‐month‐old chihuahua can mimic that of iatrogenic ureteral injury with vomiting, anorexia, and severe azotemia. Ultrasound served as a key diagnostic to visualize intestinal mechanical obstruction, an encircling ligature around a segment of jejunum with no blood flow on Doppler interrogation, and normal appearance and blood flow of the ureters and kidneys. The treatment consisted of aggressive fluid therapy, circulatory support, and emergent resection and anastomosis of the necrotic portion of the intestines. Within 48 h, the dog's azotemia was resolved, and it was reported to be doing well at 1‐month follow‐up. [ABSTRACT FROM AUTHOR]

Purpose: This case report describes a patient with a pelvic kidney associated with an aortoiliac aneurysm amenable to open repair. Methods: We chose the selective cold renal perfusion to preserve renal function. Results: Other techniques such as transient or permanent extra-anatomic bypass, extracorporeal circulation and proximal aortic double clamping are also described in this report. Conclusions: Choosing the renal perfusion technique depended on the anatomical evaluations of the kidney and the renal artery location during the preoperative period. [ABSTRACT FROM AUTHOR]

Objective This study aimed to assess the beneficial effects of N-acetylcysteine (NAC) in the treatment of contrast-induced nephropathy (CIN). Materials and Methods A prospective study was conducted in the department of cardiology of a tertiary health care hospital. A sample of 100 patients who had developed CIN through coronary angioplasty were categorized into two groups: one group treated with intravenous fluids (IVF) monotherapy and the other group treated with the combination of IVF and NAC therapy. Statistical Analysis The data were analyzed using statistical software SPSS software version 26 and statistical significance was set at p < 0.05. Independent t -test and paired t -test were used to analyze the parameters. Results The rate of incidence of CIN was found to be 10%. We observed that the IVF + NAC combination therapy significantly decreases the serum creatinine compared to IVF monotherapy (p = 0.004). Both therapies show similar treatment outcomes with no significant difference (p = 0.556) in the case of estimated glomerular filtration rate (eGFR). Based on creatinine clearance, the results show adding NAC does not impact any additional benefits (p = 000). The duration of hospital stay of the NAC group was reduced significantly (p = 0.000). Conclusion At present, we found that the treatment outcomes which we analyzed based on factors such as serum creatinine, eGFR, and creatinine clearance, are too inconsistent to conclude the beneficial effect of NAC in the management of CIN.

Background: Dengue virus remains a major public health problem with one of the hallmark pathologies is the vascular leakage caused by endothelial dysfunction which can lead to Dengue Hemorrhagic Fever (DHF) manifestation. In the status quo, no specific therapy has been discovered but rather heavily relies on judicious and frequent monitoring of intravenous fluids administration. The current guideline has discussed the roles of fluid therapy during the Dengue Shock Syndrome (DSS) stage, however, administration of early fluid intervention for DHF grade I and II remains uncharted territory. In addition, the choice and timing of colloid administration remains underexplored. As one of the widely available colloids, 5% albumin has known physiological properties that potentially minimize plasma leakage. Therefore, this study aimed to evaluate the benefit of early intervention of 5% albumin in adults with DHF in the hope of preventing the lethal progression to DSS and further, shorten the length of stay (LOS) for patients. Methods: We conducted a multicenter, open-labeled, randomized controlled trial in Jakarta and Banten to compare the effect of early intervention with 5% albumin in adult patients with DHF compared to Ringer's Lactate (RL). Statistical analyses were conducted using unpaired t-test and Mann-Whitney for normally and abnormally distributed data respectively. Results: Adult patients with a diagnosis of DHF grade I and II that being hospitalized to receive the early intervention of 5% albumin had significantly lower levels of hemoconcentration 4, 12, and 24 h (p = 0.002, 0.001, 0.003, respectively), higher platelet counts 4 h (p = 0.036), higher serum albumin levels 48 h (p = 0.036), lower proteinuria 24 and 48 h post-albumin administration (p < 0.001, < 0.001, respectively), and shorter LOS (p < 0.001) when compared to the RL group. Conclusion: Early intervention of 5% albumin showed better control on vascular integrity and function compared to ringer lactate in hospitalized adults with grade I & II DHF, thus halting the progression of DHF into DSS and other related complications which leads to faster recovery and shorter length of stay. Trial registration: The study was registered to www.clinicaltrial.gov with trial registration number NCT04076254, and registration date October 31st 2016. [ABSTRACT FROM AUTHOR]

Introduction: In adult horses, the development and evaluation of enteral electrolyte solutions containing sodium acetate for correcting hyperchloremic metabolic acidosis are still lacking, although these electrolyte and acid-base imbalances are commonly observed. The objective of this study was to evaluate the alkalinizing effect of two enteral electrolyte solutions containing different concentrations of acetate, administered via nasogastric tube in continuous flow, in adult horses with experimental hyperchloremic metabolic acidosis. Methods: Six mares aged between 3 and 10 years were used in a 6×2 crossover design, with each animal receiving both treatments. The horses were subjected to a protocol to induce hyperchloremic metabolic acidosis. They then received one of two treatments: HighAcetate (81.4 mmol/L) and LowAcetate (22.7 mmol/L) at an infusion rate of 15 mL/kg/h for 12 h. Plasma, serum, and urinary biochemical assessments; hematocrit; urinary volume, pH, and specific gravity; and blood gas analysis were measured at the following time points: T-12 h (beginning of the 12-h fast), T0h (end of fasting and beginning of the acidosis induction phase), every 2 h during the hyperchloremic metabolic acidosis induction phase (Ti2h and Ti4h), every 2 h during the 12-h enteral hydration phase (Tt2h, Tt4h, Tt6h, Tt8h, Tt10h, and Tt12h), with one sample taken at T24h (24 h after the start of acidosis induction) and another at T36h (36 h after the start of acidosis induction). Data were analyzed using descriptive statistics and analysis of variance based on a factorial design of repeated measures, with Tukey's post-hoc test or the Kruskal-Wallis test with Dunn's post-hoc test for non-parametric tests. Results: At the end of the induction phase, the animals developed moderate to severe hyperchloremic metabolic acidosis. The HighAcetate solution effectively corrected electrolyte and acid-base imbalances before the end of the treatment phase (Tt12h), while the LowAcetate solution was not effective in correcting those changes. Conclusion: The HighAcetate (81.4 mmol/L) solution is deemed an effective and safe alternative for the treatment of hyperchloremic metabolic acidosis in horses. [ABSTRACT FROM AUTHOR]

Background: Intraoperative fluid management based on pulse pressure variation has shown potential to reduce postoperative pulmonary complications (PPCs) and improve clinical outcomes in various surgical settings. However, its efficacy and safety have not been assessed in patients undergoing thoracic surgery with one-lung ventilation. Methods: Patients scheduled for pulmonary lobectomy using uniportal video-assisted thoracic surgery approach were randomly assigned to two groups. In the PPV group, fluid administration was guided by the pulse pressure variation parameter, while in the near-zero group, it was guided by conventional hemodynamic parameters. The primary outcome was the partial pressure of oxygen (PaO2)/ fraction of inspired oxygen (FiO2) ratio 15 min after extubation. The secondary outcomes included extubation time, the incidence of postoperative pulmonary complications in the first three postoperative days, and the length of hospital stay. Results: The PaO2/FiO2 ratio did not differ between the two groups (364.48 ± 38.06 vs. 359.21 ± 36.95; p = 0.51), although patients in the PPV group (n = 44) received a larger amount of both crystalloids (1145 ± 470.21 vs. 890 ± 459.31, p = 0.01) and colloids (162.5 ± 278.31 vs 18.18 ± 94.68, p = 0.002) compared to the near-zero group (n = 44). No differences were found in extubation time, type and number of PPCs, and length of hospital stay. Conclusions: PPV-guided fluid management in thoracic surgery requiring one-lung ventilation does not improve pulmonary gas exchange as measured by the PaO2/FiO2 ratio and does not seem to offer clinical benefits. Additionally, it results in increased fluid administration compared to fluid management based on conventional hemodynamic parameters. [ABSTRACT FROM AUTHOR]

Background: Our aim was to evaluate the influence of staged goal directed therapy (GDT) on postoperative pulmonary complications (PPCs), intraoperative hemodynamics and oxygenation in patients undergoing Mckeown esophagectomy. Methods: Patients were randomly divided into three groups, staged GDT group (group A, n = 56): stroke volume variation (SVV) was set at 8–10% during the one lung ventilation (OLV) stage and 8–12% during the two lung ventilation (TLV) stage, GDT group (group B, n = 56): received GDT with a target SVV of 8–12% During the entire surgical procedure, and control group (group C, n = 56): conventional fluid therapy was administered by mean arterial pressure (MAP), central venous pressure (CVP), and urine volume. The primary outcome was the incidence of postoperative pulmonary complications within Postoperative days (POD) 7. The secondary outcomes were postoperative lung ultrasound (LUS) B-lines artefacts (BLA) scoring, incidence of other complications, the length of hospital stay, intraoperative hemodynamic and oxygenation indicators included mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), cardiac output (CO), oxygenation index (OI), respiratory indices (RI), alveolar-arterial oxygen difference (Aa-DO2). Results: Patients in group A and group B had a lower incidence of PPCs (7/56 vs. 17/56 and 9/56 vs. 17/56, p < 0.05), and a fewer B-lines score on postoperative ultrasound (4.61 ± 0.51 vs. 6.15 ± 0.74 and 4.75 ± 0.62 vs. 6.15 ± 0.74, p < 0.05) compared to group C. The CI, CO, MAP, and OI were higher in group A compared to group B and group C in the stage of thoracic operation. During the abdominal operation stage, patients in group A and group B had a better hemodynamic and oxygenation indicators than group C. Conclusions: In comparison to conventional fluid therapy, intraoperative staged GDT can significantly reduce the incidence of postoperative pulmonary complications in patients undergoing McKeown esophagectomy, facilitating patient recovery. Compared to GDT, it can improve intraoperative oxygenation and stabilize intraoperative hemodynamics in patients. Trial registration: This study was registered in the Chinese Clinical Trial Registry on 24/11/2021 (ChiCTR2100053598). [ABSTRACT FROM AUTHOR]

Background: During gynecological laparoscopic surgery, pneumoperitoneum and the Trendelenburg position (TP) can lead to increased intracranial pressure (ICP). However, it remains unclear whether perioperative fluid therapy impacts ICP. The purpose of this research was to evaluate the impact of restrictive fluid (RF) therapy versus conventional fluid (CF) therapy on ICP in gynecological laparoscopic surgery patients by measuring the ratio of the optic nerve sheath diameter (ONSD) to the eyeball transverse diameter (ETD) using ultrasound. Methods: Sixty-four patients who were scheduled for laparoscopic gynecological surgery were randomly assigned to the CF group or the RF group. The main outcomes were differences in the ONSD/ETD ratios between the groups at predetermined time points. The secondary outcomes were intraoperative circulatory parameters (including mean arterial pressure, heart rate, and urine volume changes) and postoperative recovery indicators (including extubation time, length of post-anaesthesia care unit stay, postoperative complications, and length of hospital stay). Results: There were no statistically significant differences in the ONSD/ETD ratio and the ONSD over time between the two groups (all p > 0.05). From T2 to T4, the ONSD/ETD ratio and the ONSD in both groups were higher than T1 (all p < 0.001). From T1 to T2, the ONSD/ETD ratio in both groups increased by 14.3%. However, the extubation time in the RF group was shorter than in the CF group [median difference (95% CI) -11(-21 to -2) min, p = 0.027]. There were no differences in the other secondary outcomes. Conclusion: In patients undergoing laparoscopic gynecological surgery, RF did not significantly lower the ONSD/ETD ratio but did shorten the tracheal extubation time, when compared to CF.

Introduction: Ileostomy, frequently created after colorectal resections, hinders the physiologic function of the colon and can lead to dehydration and acute kidney injury due to high stoma outputs. This study aimed to evaluate the effectiveness of preventive measures on ileostomy-induced dehydration and related readmissions in a high-volume unit. Methods: In this prospective cohort study at a high-volume colorectal surgery department in Turkiye, the Prospective Ileostomy-induced Dehydration Prevention Bundle Project (PIDBP) was assessed from March 2021 to March 2022. The study enrolled patients undergoing colorectal surgery with ileostomy and involved comprehensive inpatient stoma care, education, and a structured post-discharge follow-up. The follow-up included the "Hydration follow-up scale" to monitor ileostomy output and related complications. The primary outcome was the readmission rate due to dehydration-related complications. The patients receiving the bundle intervention were compared with patients treated in the preceding year, focusing on the effectiveness of interventions such as dietary adjustments, fluid therapy, and pharmacological management. Results: In the study, 104 patients were analyzed, divided into 54 pre-bundle and 50 bundle group patients, with no significant differences in patient characteristics. While the overall readmission rate due to dehydration was 12.5%, a significant reduction in dehydration-related readmissions was observed in the bundle group compared to the pre-bundle group (2% vs. 22%, p = 0.002). Univariate analysis identified high stoma output (> 800 ml/24 h) (p < 0.001), chronic renal failure (CRF) (p = 0.01), postoperative ileus (p = 0.03), higher ASA status (p = 0.04), extended hospital stays (p = 0.03), and small bowel resections (especially in J-pouch patients) (p < 0.001) as significant predictors of readmission. Multivariate analysis revealed that the mean ileostomy output before discharge was the sole significant predictor of dehydration-related readmission (OR 1.01), with an optimal cutoff of 877.5 ml/day identified with an area under the curve (AUC) of 0.947, demonstrating high sensitivity (92.3%) and specificity (86.8%) in predicting readmission risk. Conclusion: The Prospective Ileostomy-induced Dehydration Prevention Bundle Project significantly reduced readmission rates after colorectal surgery. [ABSTRACT FROM AUTHOR]

Fluid therapy is a fundamental part of supportive therapy in critical care. However, it is also a suspected risk for endothelial glycocalyx degradation which is associated with poor clinical outcomes. This secondary analysis of RESPONSE randomized trial compares the effect of follow-up strategy (FU) on endothelial biomarkers to that of 500 ml crystalloid fluid bolus (FB) in oliguric, hemodynamically optimized intensive care unit (ICU) patients. 130 adult subjects were enrolled in two Finnish ICUs from January 2017 to November 2020. Blood and urine samples of 63 patients in FU group and 67 patients in FB group were collected before and after the intervention and analyzed using enzyme-linked immunosorbent assays. Single fluid bolus, given after median of 3887 ml (interquartile range 2842; 5359 ml) resuscitation fluids in the preceding 24 h, increased plasma hyaluronan concentration compared to the follow-up strategy (difference in medians 29.2 ng/ml with 95% CI [14.5ng/ml; 55.5ng/ml], P < 0.001). No treatment effect was detected in the plasma levels of syndecan-1, , angiopoietin-2, angiopoietin receptors Tie2 and Tie1, or in soluble thrombomodulin in the adjusted median regression analysis. The increase in hyaluronan was independent of its simultaneous renal clearance but correlated moderately with the increase in endothelium-specific Tie1. The follow-up strategy did not show consistent endothelium-sparing effect but protected against hyaluronan increase. The mechanisms and consequences of hyaluronan fluctuations need further clarification. Trial registration: clinicaltrials.gov, NCT02860572.

Background: Cytokine release syndrome (CRS) is an acute systemic inflammatory syndrome characterized by fever and multiple organ failure, which is triggered by immunotherapy or certain infections. Immune checkpoint inhibitors rarely cause immune-related adverse event- cytokine release syndrome (irAE-CRS). This article presents a case report of irAE-CRS triggered by coronavirus disease 2019 (COVID-19). Case presentation: A 60-year-old man with type 2 diabetes received nivolumab treatment for esophagogastric junction carcinoma and experienced two immune-related adverse events: hypothyroidism and skin disorder. Eleven days before his visit to our hospital, he had a fever and was diagnosed with COVID-19. Five days before his visit, he developed a fever again, along with general malaise, water soluble diarrhea, and myalgia of the extremities. On admission, the patient was in a state of multiple organ failure, and although the source of infection was unknown, a tentative diagnosis of septic shock was made. The patient's condition was unstable despite systemic management with antimicrobial agents, high-dose vasopressors, and intravenous fluids. We suspected CRS due to irAE (irAE-CRS) based on his history of nivolumab use. Steroid pulse therapy (methylprednisolone 1 g/day) was started, and the patient temporarily recovered. However, his respiratory condition worsened; consequently, he was placed on a ventilator and tocilizumab was added to the treatment. His muscle strength recovered to the point where he could live at home, and was subsequently discharged. Conclusion: In patients previously treated with immune checkpoint inhibitors, irAE-CRS should be considered as a differential diagnosis when multiple organ damage is observed in addition to inflammatory findings. It is recommended to start treatment with steroids; if the disease is refractory, other immunosuppressive therapies such as tocilizumab should be introduced as early as possible.

Background: Patients with severe infection often require careful fluid management. Intravenous linezolid can increase the fluid volume, whereas oral linezolid can effectively limit the fluid volume. However, the differences in the treatment effect and incidence of thrombocytopenia between oral and intravenous linezolid in patients with severe infection remain unclear. Methods: Patients who received linezolid in the intensive care unit of PLA General Hospital from December 2010 to December 2020 were divided into an oral group and intravenous group according to the route of administration, and we further established the PO group and PO-match group by propensity score matching. The anti-infection effect of linezolid and incidence of thrombocytopenia were compared between the two groups. Results: In total, 177 patients were enrolled in the study (59 in PO group and 118 in PO-match group). The microbial clearance rate and clinical cure rate were similar between the two groups (70.0% vs. 79.3%, P = 0.293; 72.9% vs. 83.9%, P = 0.213). The 30-day mortality rate was slightly higher in the PO group than in the PO-match group, but the difference was not statistically significant (13.6% vs. 6.8%, P = 0.138). There was no difference in the incidence of thrombocytopenia between the two groups (62.7% vs. 65.3%, P = 0.739). Conclusions: There were no significant differences in the treatment effect or incidence of thrombocytopenia between oral and intravenous administration of linezolid in patients with severe infection.

Introduction. Fluid therapy is an intervention widely used in clinical practice. However, its application is not without risks and requires a careful evaluation of patient’s tolerance and response to volume. The empirical practice of fluid resuscitation can be potentially lethal. The purpose of this review was to provide an overview of the physiological and therapeutic principles for the administration of intravenous fluids in critically ill patients, addressing special populations, such as surgical, septic, and trauma patients. Methods. A narrative review was carried out based on articles published in PUBMED, ScienceDirect, and LILACS between 2001 and 2023. MESH terms fluid therapy, crystalloid solutions, and colloids were employed. Results. A total of 371 articles were found, of which randomized clinical trials studies, narrative reviews, systematic reviews, and meta-analyses that analyzed the role of crystalloids and colloids were selected. Manuscripts published on dates outside the search range, which were considered relevant for the description of the pathophysiology and the rationale for the use of intravenous fluids, were included. Conclusion. Reflective resuscitation is based on a holistic understanding of physiology and individualization of fluid therapy. The liberal use of intravenous fluids has potential harmful effects and resuscitation strategies should be guided by individual dynamic and static measures, which provide a safe framework for fluid management.

Why you should read this article: • UK care homes are an important example of a complex environment where research is essential but faces multiple challenges in terms of rigour and methodology • This paper offers a variety of important methodological strategies to identify and address challenges that could impact findings and the ability to carry out research • It highlights the importance of taking a critical stance with all elements of the research process and illustrates the need to identify and mitigate challenges when conducting research in complex environments. Background: The evidence base for hydration practice in care homes is underdeveloped. High-quality research is therefore needed to determine what practices support older people with dementia in drinking sufficient fluid. However, methodological developments are needed to be able to do this. Aim: To highlight the methodological issues researchers encountered during a feasibility cluster, randomised controlled trial of ThinkDrink, a hydration care guide for people with dementia living in UK care homes. Discussion: This is a challenging area because of the complexity of recruitment, participation and data collection in care homes. Researchers must pay extra attention to rigour and quality in the design of their studies. There may be multiple challenges, so various strategies may be required. Conclusion: It is important that researchers continue to reflect on rigorous approaches to develop evidence in a crucial area of care, despite these challenges. Implications for practice: Researchers working in complex environments face a variety of challenges to complete methodologically rigorous research. It is important for researchers to be critical of research processes and data, to mitigate and overcome these challenges. [ABSTRACT FROM AUTHOR]

Objective: The endothelial glycocalyx layer (EGL) is the interface between the blood and the endothelium that regulates permeability. This study compared the effects of liberal and restrictive fluid therapies on atrial natriuretic peptide (ANP) release and EGL products in radical cystectomy surgery. We hypothesized that a liberal regimen would damage the glycocalyx layer, resulting in a higher serum EGL product concentration than restrictive therapy. Materials and Methods: Patients were randomized into two groups for restrictive (group R) or liberal (group L) regimens. Group R received 2 mL/kg/h Ringer’s lactate and 2 mcg/kg/h norepinephrine infusion, whereas group L received only Ringer’s lactate infusion at 10 mL/kg/h rate during the surgery. Preoperative and postoperative blood samples were obtained to evaluate ANP levels and glycocalyx degradation products. The stroke volume index, cardiac index, stroke volume variation, and systemic vascular resistance index parameters were recorded at 30-min intervals throughout the surgery. The length of stay in the hospital and intensive care unit and postoperative complications were recorded. Results: The study was completed with 39 patients. Postoperative ANP levels were higher in group L in both between- and within group examination (p<0.05). EGL constituents; syndecan-1 and hyaluronan concentrations, were higher in group L (p<0.05). Advanced hemodynamic parameters indicated insignificant changes between the groups (p>0.05). Postoperative complications and length of stay data were similar (p>0.05). Conclusion: ANP, hyaluronan, and syndecan-1 concentrations can be used as an indirect measurement method to show EGL damage and hypervolemia in major urologic surgeries. Advanced hemodynamic monitoring was ineffective for confirming hypervolemia. [ABSTRACT FROM AUTHOR]

Objectives Neurosurgical patients often receive 0.9% normal saline (NS) during the perioperative period. Theoretically, a balanced salt solution (BSS) is better than 0.9% saline. We compared the effects of two different fluids on acid–base balance, renal function, and neurological outcome in patients who underwent clipping following subarachnoid hemorrhage from a ruptured intracranial aneurysm. Materials and Methods Patients in group NS (n = 30) received 0.9% saline and group BSS (N = 30) received BSS (Plasmalyte-A) in the perioperative period for 48 hours. Comparison of arterial pH, bicarbonate, and base deficit measured preoperatively, intraoperatively (first and second hour), and postoperatively (at 24 and 48 hours) was the primary outcome of the study. The secondary outcome compared serum electrolytes, renal function tests, urine neutrophil gelatinase-associated lipocalin (NGAL), serum cystatin C, and the neurological outcome using modified Rankin score (MRS) at discharge, 1, and 3 months. Results In group NS, significantly low pH at 1-hour intraoperative period was seen compared with group BSS (7.37 ± 0.06 vs. 7.40 ± 0.05, p = 0.024). The bicarbonate level in group NS was significantly lower and the base deficit was higher at second intraoperative hour (bicarbonate: 17.49 vs. 21.99 mEq/L, p = 0.001; base deficit: 6.41 mmol/L vs. 1.89 mmol/L, p = 0.003) and at 24 hours post-surgery (bicarbonate: 20.38 vs. 21.96 mEq/L, p = 0.012; base deficit: 3.56 mmol/L vs. 2.12 mmol/L, p = 0.034)). Serum creatinine was higher in group NS at 24 hours (0.66 vs. 0.52 mg/dL, p = 0.013) and 48 hours (0.62 vs. 0.53 mg/dL, p = 0.047). Serum urea, electrolytes, cystatin, urine NGAL, and MRS were comparable. Conclusion In neurosurgical patients undergoing clipping for ruptured intracranial aneurysm, using a BSS during the perioperative period is associated with a better acid–base and renal profile. However, the biomarkers of kidney injury and long-term outcomes were comparable. [ABSTRACT FROM AUTHOR]

The article presents a neonatal case where cardiac tamponade developed as a complication of a peripherally inserted central catheter (PICC). Topics discussed include the potential risks associated with PICC placement, the management of pericardial effusion, and the importance of timely detection and intervention to prevent severe outcomes.

This article explores the management of patients with aneurysmal subarachnoid hemorrhage (aSAH) and the challenges in determining fluid balance and blood transfusion thresholds. The authors analyze a clinical trial and find that positive fluid balance is associated with lower hemoglobin levels and an increased risk of secondary infarctions and unfavorable neurologic outcomes. Packed red cell transfusions are also found to be predictive of worse neurologic outcomes. The study suggests that careful, goal-directed circulation management is crucial for maximizing favorable functional outcomes in patients with aSAH. The article emphasizes the importance of maintaining a mean daily neutral fluid balance and targeting euvolemia, while also highlighting the need for consensus among healthcare professionals on definitions and personalized management. It raises questions about the implementation of fluid balancing and the design of randomized trials for fluid management strategies. Overall, the article provides practical insights for managing patients with aSAH. [Extracted from the article]

Fluid therapy is the principal mechanism by which a clinician can stabilize a hemodynamically compromised patient. To ensure the provision of fluids is therapeutic, it is essential to know the osmolality of the administered fluid relative to the plasma of the species being treated. The clinical utility of common isotonic fluids for reptiles was determined through comparisons to the plasma osmolality of 15 Australian reptile species representing 3 genera. All sampled species had an osmolality that was either comparable, or significantly hyperosmolar, to that of the isotonic fluids. Pairwise comparisons revealed a significant difference (P < 0.05) between monitor lizards (Varanus spp.; x ¯ = 329.71 mOsm/kg) and carpet pythons (Morelia spp.; x ¯ = 294.92 mOsm/kg), and at a species-subspecies level, between eastern carpet pythons (Morelia spilota mcdowelli; x ¯ = 318.25 mOsm/kg) and Bredli carpet pythons (Morelia spilota bredli; x ¯ = 306.33 mOsm/kg). In support of previous studies, almost all species demonstrated a wider tolerable range in plasma osmolality than would be expected in mammals. Lizards in the genus Varanus demonstrated the most clinically significant results, with all species means being greater than any commercial isotonic fluid. The facultatively aquatic Mertens water monitor (Varanus mertensi) was the species with the most significant difference ( x ¯ = 344.50 mOsm/kg). A preliminary exploration of taxonomic rank (at the genus and species level) and habitat aridity was also performed to assess their utility as indicators for estimating the plasma osmolality of an unmeasured species. Neither were found to be suitable. [ABSTRACT FROM AUTHOR]

Purpose The purpose of this therapeutic update is to provide pharmacists with a general overview of the pathophysiology of hyperchloremia and describe strategies to help prevent development of this electrolyte abnormality in hospitalized patients. Summary Hyperchloremia is an electrolyte abnormality associated with an increased incidence of acute kidney injury and metabolic acidosis. Intravenous (IV) fluids utilized for volume resuscitation, medication diluents, and total parental nutrition all may contribute to the development of hyperchloremia. Current evidence suggests that administration of balanced crystalloids for either fluid resuscitation or maintenance fluids may impact serum chloride levels and patient outcomes. In multiple randomized controlled trials, administering balanced crystalloids for fluid resuscitation in critically ill patient populations did not decrease mortality. However, further analyses of subpopulations within these trials have demonstrated that patients with sepsis may benefit from receiving balanced crystalloids for initial fluid resuscitation. Results from several small studies suggest that altering the composition of these IV fluids may help prevent development of hyperchloremia. Conclusion Management of hyperchloremia is preventative in nature and can be mitigated through management of resuscitation fluids, medication diluents, and total parenteral nutrition. Inpatient pharmacists should be aware of the potential risk of fluid-associated hyperchloremia and assist with optimal fluid management to prevent and manage hyperchloremia. [ABSTRACT FROM AUTHOR]

Aim: To determine whether it was feasible, safe and acceptable for ambulance clinicians to use capillary blood ketone meters for 'high‐risk' diabetic ketoacidosis (DKA) recognition and fluid initiation, to inform the need for a full‐powered, multi‐centre trial. Methods: Adopting a stepped‐wedge controlled design, participants with hyperglycaemia (capillary blood glucose >11.0 mmol/L) or diabetes and unwell were recruited. 'High‐risk' DKA intervention participants (capillary blood ketones ≥3.0 mmol/L) received paramedic‐led fluid therapy. Participant demographic and clinical data were collated from ambulance and hospital care records. Twenty ambulance and Emergency Department clinicians were interviewed to understand their hyperglycaemia and DKA care experiences. Results: In this study, 388 participants were recruited (Control: n = 203; Intervention: n = 185). Most presented with hyperglycaemia, and incidence of type 1 and type 2 diabetes was 18.5% and 74.3%, respectively. Ketone meter use facilitated 'high‐risk' DKA identification (control: 2.5%, n = 5; intervention: 6.5%, n = 12) and was associated with improved hospital pre‐alerting. Ambulance clinicians appeared to have a high index of suspicion for hospital‐diagnosed DKA participants. One third (33.3%; n = 3) of Control and almost half (45.5%; n = 5) of Intervention DKA participants received pre‐hospital fluid therapy. Key interview themes included clinical assessment, ambulance DKA fluid therapy, clinical handovers; decision support tool; hospital DKA management; barriers to hospital DKA care. Conclusions: Ambulance capillary blood ketone meter use was deemed feasible, safe and acceptable. Opportunities for improved clinical decision making, support and safety‐netting, as well as in‐hospital DKA care, were recognised. As participant recruitment was below progression threshold, it is recommended that future‐related research considers alternative trial designs. Clinicaltrials.gov: NCT04940897.

Introduction: Fluid accumulation is associated with adverse outcomes in critically ill patients admitted to the intensive care unit (ICU). Fluid administration in the ICU may be a clinically relevant source of fluid accumulation in ICU patients. However, the extent is unknown, and no standard definition exists. We aim to provide epidemiological data on fluid accumulation, risk factors, use of fluid removal strategies, patient outcomes and describe current fluid administration practices in the ICU. Methods: We will conduct an international 14‐day inception cohort study including a minimum of 1000 acutely admitted adult ICU patients. Data will be collected from medical records and laboratory reports at baseline and daily from ICU admission to discharge with a maximum of 28 days. Follow‐up will be performed on day 90 after inclusion. The primary outcome is the number of patients with fluid accumulation. Secondary outcomes include the number of days with fluid accumulation, use of active fluid removal, days alive without life support at day 28, days alive and out of hospital day 90, and all‐cause mortality at day 90. Furthermore, we will assess risk factors for fluid accumulation and its association with 90‐day mortality and report on the types of fluid administration. Conclusion: This international inception cohort study will provide contemporary epidemiological data on fluid administration and fluid accumulation in adult ICU patients. [ABSTRACT FROM AUTHOR]

Intravenous fluids are commonly prescribed to children in hospitals. However, there are risks associated with their use. In order to safely prescribe these clinicians should understand the indications for their use, the principles underpinning their use and know the likely complications associated with intravenous fluid administration in children. Intravenous fluids should be prescribed depending on individual needs of each child and with careful monitoring and re-assessment. This review aims to provide a general approach to fluid prescription in children, providing some background of different physiological principles, different fluid composition, and the role of anti-diuretic hormone in fluid homeostasis. Fluid prescription is discussed, with an approach taking into consideration resuscitation boluses, dehydration, replacing ongoing losses and maintenance requirements. Case examples are provided to further facilitate readers' comprehension. Electrolyte abnormalities and an approach to the management of deranged electrolytes is addressed. Complications associated with fluid administration are highlighted, in particular, emphasizing the assessment and emergency management of the child with suspected cerebral oedema or hyponatraemic encephalopathy. Special consideration and discussion is given to the differing approach to fluid management of children in the setting of burns or diabetic ketoacidosis. [ABSTRACT FROM AUTHOR]

• Normal saline has been considered to have deleterious effects on kidney function. • We compared balanced solution versus saline in off-pump coronary bypass surgery. • The study did not demonstrate a significant difference in acute kidney injury. To determine whether balanced solutions can reduce the incidence of acute kidney injury after off-pump coronary artery bypass surgery compared with saline. Randomized controlled trial. Single tertiary care center. Patients who underwent off-pump coronary artery bypass surgery between June 2014 and July 2020. Balanced solution-based chloride-restrictive intravenous fluid strategy. The primary outcome was acute kidney injury within 7 postoperative days, as defined by the 2012 Kidney Disease: Improving Global Outcomes Clinical Practice Guideline. The incidence of acute kidney injury was 4.4% (8/180) in the balanced group and 7.3% (13/178) in the saline group. The difference was not statistically significant (risk difference, −2.86%; 95% confidence interval [CI], −7.72% to 2.01%; risk ratio, 0.61, 95% CI, 0.26 to 1.43; p = 0.35). Compared with the balanced group, the saline group had higher levels of intraoperative serum chloride and lower base excess, which resulted in a lower pH. In patients undergoing off-pump bypass surgery with a normal estimated glomerular filtration rate, the intraoperative balanced solution-based chloride-restrictive intravenous fluid administration strategy did not decrease the rate of postoperative acute kidney injury compared with the saline-based chloride-liberal intravenous fluid administration strategy.

Shock is circulatory insufficiency, inadequate oxygen delivery, and cellular hypoxia. Intravenous fluids are essential for shock management. Despite treatment, patients can face persistent shock with ongoing hypotension, contributing to higher mortality. This analysis aims to quantify hypotensive non-traumatic cases in an Australian ambulance service, determine persistent hypotension prevalence, and assess paramedic-administered intravascular fluids' impact on blood pressure changes. This study is a retrospective analysis of prehospital fluid resuscitation by New South Wales Ambulance paramedics during 2022. Hypotension is defined as a systolic blood pressure of ≤ 90 mmHg, and persistent hypotension is a systolic blood pressure consistently below 90 mmHg across all observations, with a final blood pressure below 90 mmHg. This study aimed to determine the volume of fluid resuscitation at which a plateau in population-level systolic blood pressure response is observed, by calculating the derivative of the fitted logistic regression model. Moreover, this analysis identified the relative contribution of factors influencing the probability of an attempt at intravenous or intraosseous access using machine learning. Among 796,865 attendances, 23,049 (2.9%) involved non-traumatic patients with hypotension. In total 7,388 (32.1%) of the hypotensive cases resulted in persistent hypotension, of which 3,235 (43.8%) received Hartmann's solution and 1,745 (53.9%) received at least 500 ml of fluids but still had hypotension. The model showed that systolic blood pressure tends to stop increasing after 500–600 milliliters of fluid are given. This suggests that, on average, giving more fluid than this may not raise blood pressure further in a prehospital setting, though individual patient needs can differ. The top four factors from the machine learning shows that as initial respiratory rate goes up, the probability of intravascular access rises. Transport times less than 20 min are associated with a smaller chance of access and younger patients are less likely to receive an attempt. Finally, extremes of systolic blood pressure are more likely to receive access attempts. This study found that three percent of non-traumatic attendances have at least one episode of hypotension, and that more than half of these have persistent hypotension. Only 44% of persistently hypotensive received fluids, and half of persistently hypotensive patients stayed hypotensive despite a reasonable volume of prehospital crystalloids. [ABSTRACT FROM AUTHOR]

Emergency medical services (EMS) clinicians are tasked with early fluid resuscitation for patients with sepsis. Traditional methods for prehospital fluid delivery are limited in speed and ease-of-use. We conducted a comparative effectiveness study of a novel rapid infusion device for prehospital fluid delivery in suspected sepsis patients. This pre-post observational study evaluated a hand-operated, rapid infusion device in a single large EMS system from July 2021-July 2022. Prior to device deployment, EMS clinicians completed didactic and simulation-based device training. Data were extracted from the EMS electronic health record. Eligible patients included adults with suspected sepsis treated by EMS with intravenous fluids. The primary outcome was the proportion of patients receiving goal fluid volume (at least 500 mL) prior to hospital arrival. Secondary outcomes included in-hospital mortality, disposition, and length of stay. Multivariable logistic regression was used to compare outcomes between 6-month pre- and post-implementation periods (July-December 2021 and February-July 2022, respectively), adjusting for patient demographics, abnormal prehospital vital signs, and EMS transport interval. Of 1,180 eligible patients (552 in the pre-implementation period; 628 in the post-implementation period), the mean age was 72 years old, 45% were female, and 25% were minority race-ethnicity. Median (interquartile range) fluid volume (in mL) increased between the pre- and post-implementation periods (600 [400,1,000] and 850 [500–1,000], respectively). Goal fluid volume was achieved in 70% of pre-implementation patients and 82% of post-implementation patients. In adjusted analysis, post-implementation patients were significantly more likely to receive goal fluid volume than pre-implementation patients (adjusted odds ratio (aOR) 2.00, 95% confidence interval (CI) 1.51–2.66). Pre-post in-hospital mortality was not significantly different (aOR 0.91, 95% CI 0.59–1.39). In a single EMS system, sepsis education and introduction of a rapid infusion device was associated with achieving goal fluid volume for suspected sepsis. Further research is needed to assess the clinical effectiveness of infusion device implementation to improve sepsis patient outcomes. [ABSTRACT FROM AUTHOR]

Simple Summary: The purpose of this study was to evaluate the efficacy of using the pleth variability index (PVi) to guide fluid therapy in dogs undergoing surgery under general anesthesia compared to conventional fixed-fluid-rate administration. Twenty-seven dogs meeting specific criteria were randomly assigned to either a conventional fluid management (CFM) group or a PVi-guided (PVi) group. The CFM group received a fixed rate of fluid, while the PVi group had their fluid rate adjusted based on their PVi values. Results showed that dogs in the PVi group received less total fluid and experienced fewer hypotensive episodes compared to the CFM group. In addition, the mean arterial pressure (MAP) was significantly higher in the PVi group during surgery. These findings suggest that PVi-guided fluid therapy may result in more targeted fluid administration and improve the hemodynamic stability in anesthetized dogs. However, further studies with larger sample sizes are needed to confirm these results and explore the broader applicability of the PVi in veterinary anesthesia. The aim of this prospective, randomized clinical trial was to evaluate the use of the pleth variability index (PVi) to guide the rate of intraoperative fluid therapy compared to a traditional fixed-fluid-rate approach in ASA 1–2 dogs undergoing surgery. Twenty-seven dogs met the inclusion criteria and were randomly assigned to the conventional fluid management group (CFM, n = 12) or the PVi-guided group (PVi, n = 15). The CFM group received a fixed rate of 5 mL kg−1 h−1 of crystalloid solution, while in the PVi group the rate was continuously adjusted based on the PVi: PVi < 14% = 3 mL kg−1 h−1; 14% ≤ PVi ≥ 20% = 10 mL kg−1 h−1; and PVi > 20% = 15 mL kg−1 h−1. Hypotension (MAP < 65 mmHg) in the CFM was treated with a maximum of two fluid boluses (5 mL kg−1 in 10 min) and in the case of no response, dobutamine (1–3 mcg kg−1 min−1) was administered. In the PVi group, the treatment of hypotension was similar, except when the PVi > 14%, when dobutamine was started directly. Total fluid volume was significantly lower in the PVI group (0.056 ± 0.027 mL kg−1 min−1) compared to the CFM group (0.132 ± 0.115 mL kg−1 min−1), and the incidence of hypotension was lower (p = 0.023) in the PVi group (0%) compared to the CFM group (41%). The mean arterial pressure (MAP) was significantly higher in the PVi group during surgery. Dobutamine was never administered in either group. Preliminary data suggest that the PVi may be considered as a potential target to guide fluid therapy in dogs; larger studies are needed, especially in cases of cardiovascular instability.

Septic abortion can lead to severe maternal morbidity and mortality. The management of septic abortion can be complicated by a history of radical trachelectomy and transabdominal cerclage placement. A 33-year-old G1P0 at 17 weeks and 6 days gestation presented in severe septic shock after being diagnosed 6 days prior with previable rupture of membranes at an outside hospital and managed expectantly. History was notable for cervical adenocarcinoma status post radical trachelectomy and transabdominal cerclage placement. Due to uterine occlusion from the cerclage, the patient underwent emergent uterine evacuation via an abdominal approach. The risks and benefits of expectant management of pre-viable rupture of membranes in patients with abdominal cerclage should be weighed very cautiously. Among women with abdominal cerclage for whom uterine evacuation is indicated, a transabdominal approach may be necessary. [ABSTRACT FROM AUTHOR]

Fluid creep occurs when resuscitation after extensive burn injury reaches volumes higher than predicted. Since this has been described in patients with high opioid requirements, continuous analgesics and sedatives, including dexmedetomidine, have been avoided during resuscitation. This study sought to describe the impact of dexmedetomidine on fluid resuscitation requirements. This retrospective cohort study included adult patients with burns greater than 20% total body surface area (TBSA) resuscitated between January 2017 and June 2022 at a regional burn center. Patients deceased within 48 hours of burn were excluded. The primary outcome was volume of fluid required in the first 24 and 48 hours postburn. Secondary outcomes were the incidence of fluid-related adverse events within 7 days postburn. A total of 170 patients were included: 55 in the dexmedetomidine cohort and 115 in the control cohort. After propensity matching for variables associated with fluid creep, the dexmedetomidine cohort required 4.2 ± 1.7 mL/kg/%TBSA in the first 24 hours compared to 3.6 ± 1.1 mL/kg/%TBSA in the control cohort (P = 0.03). The difference was no longer significant at 48 hours (P = 0.11). There were no differences in the incidence of acute respiratory distress syndrome, delayed escharotomy/fasciotomy, intra-abdominal hypertension, or renal replacement therapy. Dexmedetomidine exposure during acute resuscitation resulted in increased fluid requirements in the first 24 hours, suggesting it is independently associated with fluid creep; however, this increase was not sustained at 48 hours. Clinical significance of this finding is unclear, as there was no increase in adverse events related to excessive fluid resuscitation between cohorts. [ABSTRACT FROM AUTHOR]

Purpose: Planning intraoperative fluid therapy in patients undergoing major abdominal surgery is important. It was aimed to define the difference between fluid therapy protocols for renal function, bleeding and postoperative service follow-ups. Materials and methods: This is an observational case-controlled prospective study. Sixty patients aged 18–65 years who had undergone pancreatic surgery between December 2023– February 2023 were included in the study. Liberal (Group 1; n = 30) and targeted fluid therapies (Group 2; n = 30) were administered to the patients. Liberal fluid therapy was planned with 8–10 ml/kg/h crystalloid infusion. The targeted fluid therapy (TFT) group (Group 2; n = 30) began with a 2 ml/kg/h crystalloid infusion at the baseline. Additional fluid boluses were given in 250 ml of colloid infused over 10 min if PVI was > 13% for at least five minutes. The patients were staged using the KDIGO (Kidney Disease: Improving Global Outcomes) criteria. The amount of bleeding during surgery was recorded for both groups. Results: No significant difference was observed in postoperative renal function. A significant difference was observed in the amount of intraoperative bleeding. The amount of bleeding was greater in patients managed with liberal fluid therapy. No significant difference was observed between the groups in the oral intake (hour), drain withdrawal (hour) mobilization (hour) and discharge (day) times and there isn't any statistically significant differance between groups in cost effectivity (p>0.05). Conclusion: Kidney function was preserved during individualized targeted fluid therapy using non-invasive haemodynamic monitoring parameters. [ABSTRACT FROM AUTHOR]

Background: Postoperative thirst is one of the most intense, common and easily ignored subjective discomforts in patients after gynecological surgery. This study aimed to investigate whether early oral hydration on demand in the postanesthesia care unit (PACU) after gynecological laparoscopy under general anesthesia can appease postoperative thirst and increase patient comfort. Methods: Participants were randomized into the intervention and control groups. Patients in the intervention group were allowed to achieve early oral hydration on demand in the PACU if they were evaluated as fully conscious, with stable vital signs, grade 5 muscle strength, and well-recovered cough and swallowing reflex. However, the total amount of water intake throughout the entire study should not exceed 0.5mL/kg. During the study, the frequency of water intake, the total amount of water intake and adverse events were accurately recorded. The control group was managed according to the routine procedures and began to drink water 2 h after anesthesia. The intensity of thirst and subjective comfort in patients were assessed using the visual analog scale (VAS) when they entered and left the PACU. Results: No statistically significant differences were identified in age, height, weight, body mass index, pre-operative fasting time, duration of surgery, intraoperative fluid intake, intraoperative blood loss, intraoperative urine volume, and thirst intensity and subjective comfort scores between the groups before intervention (P > 0.05). After intervention, the VAS score for thirst intensity in the intervention group significantly decreased (P < 0.05), and the VAS score for subjective comfort in the intervention group significantly increased (P < 0.05). No adverse events were detected in both groups during the entire study. Conclusion: Early oral hydration on demand in the PACU can safely and effectively relieve postoperative thirst in patients, and improve patient comfort after gynecological laparoscopy. Trial registration: This single-center, prospective, randomized controlled trial was registered at the Chinese Clinical Trial Center on April 27, 2023. The registration number of this study is ChiCTR2300070985. [ABSTRACT FROM AUTHOR]

Introduction: This case report reports an unusual occurrence of gossypiboma, which refers to the accidental retention of surgical materials like sponges in the peritoneal cavity. The term is derived from "gossypium" (cotton) and "boma" (place of concealment). Its incidence varies with surgical type, posing diagnostic challenges due to nonspecific symptoms and equivocal imaging. Despite its rarity, gossypiboma poses significant risks, including intestinal obstruction and abscess formation. Case presentation: A 37-year-old woman with ten previous pregnancies and an emergent caesarean section presented with abdominal pain. Examination and ultrasound suggested an ovarian cyst. During surgery, a 10 × 10 cm gauze-filled mass adherent to the ovary and jejunum was found. Postoperatively, she recovered well with no complications. The patient was treated with intravenous fluids and antibiotics for five days post-surgery and recovered without any complications. She was discharged from the hospital five days after the procedure. Conclusion: To the best of our knowledge, this is the first reported case of gossypiboma in Sudan in 2024, highlighting diagnostic challenges and the need for preventive protocols. Root cause analysis of accidents, enhanced training, application of advanced technologies and a collaborative culture in the operating room can prevent the occurrence of such incidents. This case underscores the importance of meticulous surgical protocols and continuous improvement in safety measures to prevent retained surgical items, ensuring patient safety and optimal outcomes.

Background: Fluid administration is the first line treatment in intensive care unit (ICU) patients with sepsis and septic shock. While fluid boluses administration can be titrated by predicting preload dependency, the amount of other forms of fluids may be more complex to be evaluated. We conducted a retrospective analysis in a tertiary hospital, to assess the ratio between fluids given as boluses and total administered fluid intake during early phases of ICU stay, and to evaluate the impact of fluid strategy on ICU mortality. Data related to fluid administration during the first four days of ICU stay were exported from an electronic health records system (ICCA®, Philips Healthcare). Demographic data, severity score, norepinephrine dose at ICU admission, overall fluid balance and the percentage of different fluid components of the overall volume administered were included in a multivariable logistic regression model, evaluating the association with ICU survival. Results: We analyzed 220 patients admitted with septic shock and sepsis-induced hypotension from 1st July 2021 to 31st December 2023. Fluid boluses and maintenance represented 49.3% ± 22.8 of the overall fluid intake, being balanced solution the most represented (40.4% ± 22.0). The fluid volume for drug infusion represented 34.0% ± 2.9 of the total fluid intake, while oral or via nasogastric tube fluid intake represented 18.0% ± 15.7 of the total fluid intake. Fluid volume given as boluses represented 8.6% of the total fluid intake over the four days, with a reduction from 25.1% ± 24.0 on Day 1 to 4.8% ± 8.7 on Day 4. A positive fluid balance [OR 1.167 (1.029–1.341); p = 0.021] was the most important factor associated with ICU mortality. Non-survivors (n = 66; 30%) received a higher amount of overall inputs than survivors only on Day 1 [2493 mL vs. 1855 mL; p = 0.022]. Conclusions: This retrospective analysis of fluids given over the early phases of septic shock and sepsis-induced hypotension showed that the overall volume given by boluses ranges from about 25% on Day 1 to about 5% on Day 4 from ICU admission. Our data confirms that a positive fluid balance over the first 4 days of ICU is associated with mortality. [ABSTRACT FROM AUTHOR]

Heart–lungs interactions are related to the interplay between the cardiovascular and the respiratory system. They result from the respiratory-induced changes in intrathoracic pressure, which are transmitted to the cardiac cavities and to the changes in alveolar pressure, which may impact the lung microvessels. In spontaneously breathing patients, consequences of heart–lungs interactions are during inspiration an increase in right ventricular preload and afterload, a decrease in left ventricular preload and an increase in left ventricular afterload. In mechanically ventilated patients, consequences of heart–lungs interactions are during mechanical insufflation a decrease in right ventricular preload, an increase in right ventricular afterload, an increase in left ventricular preload and a decrease in left ventricular afterload. Physiologically and during normal breathing, heart–lungs interactions do not lead to significant hemodynamic consequences. Nevertheless, in some clinical settings such as acute exacerbation of chronic obstructive pulmonary disease, acute left heart failure or acute respiratory distress syndrome, heart–lungs interactions may lead to significant hemodynamic consequences. These are linked to complex pathophysiological mechanisms, including a marked inspiratory negativity of intrathoracic pressure, a marked inspiratory increase in transpulmonary pressure and an increase in intra-abdominal pressure. The most recent application of heart–lungs interactions is the prediction of fluid responsiveness in mechanically ventilated patients. The first test to be developed using heart–lungs interactions was the respiratory variation of pulse pressure. Subsequently, many other dynamic fluid responsiveness tests using heart–lungs interactions have been developed, such as the respiratory variations of pulse contour-based stroke volume or the respiratory variations of the inferior or superior vena cava diameters. All these tests share the same limitations, the most frequent being low tidal volume ventilation, persistent spontaneous breathing activity and cardiac arrhythmia. Nevertheless, when their main limitations are properly addressed, all these tests can help intensivists in the decision-making process regarding fluid administration and fluid removal in critically ill patients.

Introduction: Insufficient knowledge of intravenous fluid therapy is a significant challenge contributing to morbidity and mortality in hospitalized patients. Nurses play a critical role in evaluating patients' fluid and electrolyte balance as well as in restoring fluid levels. Various studies have indicated a deficiency in nurses' knowledge of intravenous therapy, yet this remains understudied in many settings, including Namibia. Objectives: To assess nurses' knowledge of intravenous fluid therapy and to describe the variables associated with knowledge of intravenous fluid therapy at a teaching hospital in Namibia. Methods: A cross-sectional online survey involving 164 nurses who were recruited using total population sampling. Data were collected between September and November 2021, using a self-administered 14-item validated tool (α = 0.8). Data analysis was conducted using SPSSv28.0 software. Results: The majority of nurses (84%) in this study exhibited an insufficient level of knowledge regarding intravenous therapy, with only a minority (16%) demonstrating a moderately adequate understanding of intravenous fluid therapy. A significant positive correlation was found between educational qualification and knowledge of intravenous therapy (r = 0.21; p =.01). Conclusion: The study's results indicate a worrying trajectory in nurses' knowledge of intravenous therapy. These findings underscore the need for hospitals to establish comprehensive training programs for nurses to guarantee the provision of secure and efficient intravenous therapy. Additional research is needed to investigate how educational qualifications impact patient outcomes related to intravenous therapy. [ABSTRACT FROM AUTHOR]

Background: The selection of adequate indicators of tissue hypoxia for guiding the resuscitation process of septic patients is a highly relevant issue. Current guidelines advocate for the use of lactate as sole metabolic marker, which may be markedly limited, and the integration of different variables seems more adequate. In this study, we explored the metabolic profile and its implications in the response to the administration of a fluid challenge in early septic shock patients. Methods: Observational study including septic shock patients within 24 h of ICU admission, monitored with a cardiac output estimation system, with ongoing resuscitation. Hemodynamic and metabolic variables were measured before and after a fluid challenge (FC). A two-step cluster analysis was used to define the baseline metabolic profile, including lactate, central venous oxygen saturation (ScvO2), central venous-to-arterial carbon dioxide difference (PcvaCO2), and PcvaCO2 corrected by the difference in arterial-to-venous oxygen content (PcvaCO2/CavO2). Results: Seventy-seven fluid challenges were analyzed. Cluster analysis revealed two distinct metabolic profiles at baseline. Cluster A exhibited lower ScvO2, higher PcvaCO2, and lower PcvaCO2/CavO2. Increases in cardiac output (CO) were associated with increases in VO2 exclusively in cluster A. Baseline isolated metabolic variables did not correlate with VO2 response, and changes in ScvO2 and PcvaCO2 were associated to VO2 increase only in cluster A. Conclusions: In a population of early septic shock patients, two distinct metabolic profiles were identified, suggesting tissue hypoxia or dysoxia. Integrating metabolic variables enhances the ability to detect those patients whose VO2 might increase as results of fluid administration. [ABSTRACT FROM AUTHOR]

Background: Pediatric patients undergoing liver transplantation are particularly susceptible to complications arising from intraoperative fluid management strategies. Conventional liberal fluid administration has been challenged due to its association with increased perioperative morbidity. This study aimed to assess the impact of intraoperative high-volume fluid therapy on pediatric patients who are undergoing living donor liver transplantation (LDLT). Methods: Conducted at the Children's Hospital of Chongqing Medical University from March 2018 to April 2021, this retrospective study involved 90 pediatric patients divided into high-volume and non-high-volume fluid administration groups based on the 80th percentile of fluid administered. We collected the perioperative parameters and postoperative information of two groups. Multivariable logistic regression was utilized to assess the association between estimated blood loss (EBL) and high-volume FA. Kaplan-Meier survival analysis was used to compare patient survival after pediatric LDLT. Results: Patients in the high-volume FA group received a higher EBL and longer length of stay than that in the non-high-volume FA group. Multivariate logistic regression analysis indicated that hours of maintenance fluids and fresh frozen plasma were significantly associated risk factors for the occurrence of EBL during pediatric LDLT. In addition, survival analysis showed no significant differences in one-year mortality between the groups. Conclusions: High-volume fluid administration during LDLT is linked with poorer intraoperative and postoperative outcomes among pediatric patients. These findings underscore the need for more conservative fluid management strategies in pediatric liver transplantations to enhance recovery and reduce complications. [ABSTRACT FROM AUTHOR]

Introduction: Ultrasonography as a guide for intravenous (IV) fluid therapy is increasingly accepted within the spheres of acute care. Initial investigations and protocols often focused on measures of arterial flow as an objective approach for personalising organ 'perfusion.' More recently, and with literature associating excessive IV fluid with adverse outcomes, venous ultrasound as a measure of organ 'congestion' is taking hold. Yet, arterial (i.e., 'perfusion') and venous (i.e., 'congestion') Doppler ultrasound measures are often performed separately and can be time‐consuming, especially for novices. Methods: We report a case, wherein venous and arterial Doppler were simultaneously measured using a wireless, wearable ultrasound as a means to optimise flow without congestion. Results: Before IV volume expansion, the patient had Doppler measures consistent with low central venous pressure (CVP) and stroke volume (SV). Following IV volume expansion, venous Doppler remained the same; however, carotid corrected flow time (ccFT) increased significantly. Conclusion: A framework for venous‐arterial Doppler enhanced resuscitation (VADER) can be used to guide IV volume in patients at risk for venous congestion. [ABSTRACT FROM AUTHOR]

Early diagnosis and prompt management are essential to enhance the outcomes of patients with sepsis and septic shock. Over the past two decades, evidence-based guidelines have guided appropriate treatment and recommended the implementation of a bundle strategy to deliver fundamental treatments within the initial hours of care. Shortly after its introduction, the implementation of a bundle strategy has led to a substantial decrease in mortality rates across various health care settings. The primary advantage of these bundles is their universality, making them applicable to all patients with sepsis. However, this same quality also represents their primary disadvantage as it fails to account for the significant heterogeneity within the septic patient population. Recently, the individualization of treatments included in the bundle has been suggested as a potential strategy for further improving the prognosis of patients with sepsis. New strategies for the early identification of microorganisms and their resistance patterns, advanced knowledge of antibiotic kinetics in critically ill patients, more conservative fluid therapy in specific patient populations, and early use of alternative vasopressors to catecholamines, as well as tailored source control based on patient conditions and site of infection, are potential approaches to personalize initial care for specific subgroups of patients. These innovative methodologies have the potential to improve the management of septic shock. However, their implementation in clinical practice should be guided by solid evidence. Therefore, it is imperative that future research evaluate the safety, efficacy, and cost-effectiveness of these strategies. [ABSTRACT FROM AUTHOR]

Purpose: Nowadays, it is largely accepted that albumin should not be used in hypoalbuminemia or for nutritional purpose. The most discussed indication of albumin at present is the resuscitation in shock states, especially distributive shocks such as septic shock. The main evidence-based indication is also liver disease. In this review, we provided updated evidence-based instruction for definite and potential indications of albumin administration in clinical practice, with appropriate dosing and duration. Methods: Data collection was carried out until November 2023 by search of electronic databases including PubMed, Google Scholar, Scopus, and Web of Science. GRADE system has been used to determine the quality of evidence and strength of recommendations for each albumin indication. Results: A total of 165 relevant studies were included in this review. Fluid replacement in plasmapheresis and liver diseases, including hepatorenal syndrome, spontaneous bacterial peritonitis, and large-volume paracentesis, have a moderate to high quality of evidence and a strong recommendation for administering albumin. Moreover, albumin is used as a second-line and adjunctive to crystalloids for fluid resuscitation in hypovolemic shock, sepsis and septic shock, severe burns, toxic epidermal necrolysis, intradialytic hypotension, ovarian hyperstimulation syndrome, major surgery, non-traumatic brain injury, extracorporeal membrane oxygenation, acute respiratory distress syndrome, and severe and refractory edema with hypoalbuminemia has a low to moderate quality of evidence and weak recommendation to use. Also, in modest volume paracentesis, severe hyponatremia in cirrhosis has a low to moderate quality of evidence and a weak recommendation. Conclusion: Albumin administration is most indicated in management of cirrhosis complications. Fluid resuscitation or treatment of severe and refractory edema, especially in patients with hypoalbuminemia and not responding to other treatments, is another rational use for albumin. Implementation of evidence-based guidelines in hospitals can be an effective measure to reduce inappropriate uses of albumin. [ABSTRACT FROM AUTHOR]

Background: Neurological impairment (NI) relates to disorders of the central nervous system. The specific aetiology of NI varies but includes genetic, congenital abnormalities or brain injury. In children with severe NI, feeding impairments can lead to undernutrition, and some children require a feeding tube. Although tube feeding improves overall nutritional status, it has also been associated with excess body fat. Commercially available enteral formulas that are low in energy, hydrolysed and nutritionally adequate for protein and micronutrients are available to mitigate gastrointestinal symptoms and obesity. Methods: This is a retrospective multicentre study of children who attended NI clinics between January 2022 and July 2023. Data were collected before and 1 month after receiving a low‐energy, partially hydrolysed enteral formula (0.6 kcal/mL) on demographic data (age, sex, ethnicity and NI diagnosis), anthropometric measurements (weight, height, weight‐for‐age Z‐score, height‐for‐age Z‐score, body mass index [BMI] Z‐score) and feed regimen (feed volume, total fluids and type of formula/supplements). Results: Dietitians collected data on 28 children, the median age was 7 years (interquartile range [IQR] 3, 8). The most frequently recorded NI was cerebral palsy, in 13 of 28 children (48%). Before the formula switch, the most frequently reported gastrointestinal symptom was constipation, in 13 of 28 children. Within 1 month of switching to a low‐energy, hydrolysed formula, 10 of the 13 (77%) children reported an improvement in constipation. Before the formula switch, all 28 children were experiencing excessive weight gain. After the formula was switched to low‐energy, hydrolysed formula, dietitians reported that 20 of the 28 (76%) children's weight either stabilised or reduced after 1 month. There was no statistically significant difference in weight‐for‐age Z‐score or BMI Z‐scores postswitch of formula (p‐value 0.1 and 0.09, respectively). Fibre intake increased significantly from 3.3 to 8.1 g/day (p‐value < 0.01) after formula switch. The number of children whose feed regimens were simplified after switching to a low‐energy, partially hydrolysed formula was 24 of 28 (91%). Conclusions: Children with an NI who have gastrointestinal symptoms may benefit from a low‐energy, hydrolysed enteral formula to maximise feed tolerance and promote healthy weight gain. In addition, changing to a low‐energy, hydrolysed formula may simplify feed regimens by eliminating the need for additional electrolytes, multivitamins and fluid boluses. Healthcare professionals should be knowledgeable about the effectiveness and availability of a low‐energy, hydrolysed formula. Highlights: A low‐energy, partially hydrolysed enteral formula may promote weight stabilisation and optimise feed tolerance in tube‐fed children with an NI.Switching to a low‐energy, partially hydrolysed enteral formula may simplify overly complicated feed regimens in tube‐fed children with an NI by excluding the need for additional multivitamins or electrolytes.Healthcare professionals should be knowledgeable about the availability of low‐energy, hydrolysed formulas.
