This study aimed to determine the prevalence of adverse events in mechanically ventilated adults with COVID-19 who have undergone prone positioning. A total of 100 patients were included retrospectively; 60% were males, the mean age was 64.8 ± 9.1 years, and hospital mortality was 47%. In all, we recorded 118 removals of catheters and tubes in 66 patients; 29.6% were removals of a nasogastric tube, 18.6% of an arterial line, 14.4% of a urinary catheter, and 12.7% of a central venous catheter. Reintubation or repositioning of a tracheotomy tube was required in 19 patients (16.1%), and cardiopulmonary resuscitation in 2 patients (1.7%). We recorded a total of 184 pressure ulcers in 79 patients (on anterior face in 38.5%, anterior thorax in 23.3% and any extremity anteriorly in 15.2%). We observed that body weight (p = 0.021; β = 0.09 (CI95: 0.01–0.17)) and the cumulative duration of prone positioning (p = 0.005; β = 0.06 (CI95: 0.02–0.11)) were independently associated with the occurrence of any adverse event. The use of prone positioning in our setting was associated with a greater number of adverse events than previously reported. Body weight and cumulative duration of prone positioning were associated with the occurrence of adverse events; however, other factors during a COVID-19 surge, such as working conditions, staffing, and staff education, could also have contributed to a high prevalence of adverse events.

Angiotensin II is a recently introduced vasopressor, which has been available since 2017. The novelty and the relatively high cost of angiotensin II currently limit its broader application. It induces vasoconstriction by activating the renin–angiotensin–aldosterone system and is currently the sole vasopressor functioning through this pathway. Beyond vasoconstriction, angiotensin II also affects various other physiological processes. Current evidence supports its use in managing vasoplegic and cardiogenic shock in patients who are unresponsive to catecholamines and vasopressin. However, due to limited data, the optimal timing for initiating therapy with angiotensin II, strategies for combining it with other vasopressors, and strategies for its discontinuation remain unclear. Ongoing and planned studies aim to address some of these uncertainties. This article reviews the physiological and pathophysiological effects of angiotensin II, describes its pharmacology, and provides a narrative review of the current literature. [ABSTRACT FROM AUTHOR]

Background: Cardiac arrest remains one of the leading causes of death. After successful resuscitation of patients in cardiac arrest, post-cardiac arrest syndrome develops, part of it being an impaired cerebral blood flow autoregulation. Monitoring cerebral blood flow autoregulation after cardiac arrest is important for optimizing patient care and prognosticating patients' survival, yet remains a challenge. There are still gaps in clinical implications and everyday use. In this article, we present a systematic review of studies with different methods of monitoring cerebral blood flow autoregulation after non-traumatic cardiac arrest. Methods: A comprehensive literature search was performed from 1 June 2024 to 27 June 2024 by using multiple databases: PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials. Inclusion criteria were studies with an included description of the measurement of cerebral blood flow autoregulation in adult patients after non-traumatic cardiac arrest. Results: A total of 16 studies met inclusion criteria. Our data show that the most used methods in the reviewed studies were near-infrared spectroscopy and transcranial Doppler. The most used mathematical methods for calculating cerebral autoregulation were cerebral oximetry index, tissue oxygenation reactivity index, and mean flow index. Conclusions: The use of various monitoring and mathematical methods for calculating cerebral blood flow autoregulation poses a challenge for standardization, validation, and daily use in clinical practice. In the future studies, focus should be considered on clinical validation and transitioning autoregulation monitoring techniques to everyday clinical practice, which could improve the survival outcomes of patients after cardiac arrest.

Background and Objectives: Survival with favorable neurologic outcomes after out-of-hospital cardiac arrest (OHCA) remains elusive. Post-cardiac arrest syndrome (PCAS) involves myocardial and neurological injury, ischemia-reperfusion response, and underlying pathology. Neurologic injury is a crucial determinant of survival and functional outcomes, with damage caused by free radicals among the responsible mechanisms. This study explores the feasibility of adding intravenous vitamin C to the treatment of OHCA survivors, aiming to mitigate PCAS. Vitamin C, a nutrient with antioxidative and free radical-scavenging properties, is often depleted in critically ill patients. Materials and Methods: This randomized, double-blinded trial was conducted at a tertiary-level university hospital with adult OHCA survivors. Participants received either standard care or the addition of 1.5 g of intravenous vitamin C every 12 h for eight consecutive doses. Neurologic injury was assessed using neuron-specific enolase (NSE) levels, with additional clinical and laboratory outcomes, such as enhanced neuroprognostication factors, inflammatory markers, and cardiac parameters. Results: NSE levels were non-significantly higher in patients who received vitamin C compared to the placebo group (55.05 µg/L [95% confidence interval (CI) 26.7–124.0] vs. 39.4 µg/L [95% CI 22.6–61.9], p > 0.05). Similarly, a non-significantly greater proportion of patients in the vitamin C group developed myoclonus in the first 72 h. We also observed a non-significantly shorter duration of mechanical ventilation, fewer arrhythmias, and reduced length of stay in the intensive care unit in the group of patients who received vitamin C (p = 0.031). However, caution is warranted in interpretation of our results due to the small number of participants. Conclusions: Our findings suggest that intravenous vitamin C should not be used outside of clinical trials for OHCA survivors. Due to the small sample size and conflicting results, further research is needed to determine the potential role of vitamin C in post-cardiac arrest care. [ABSTRACT FROM AUTHOR]

Modulating body temperature, mostly through the use of antipyretics, is a commonly employed therapeutic intervention in medical practice. However, emerging evidence suggests that hyperthermia could serve as an adjuvant therapy for patients with infection. We performed a narrative review to explore the application of therapeutic hyperthermia in the treatment of infection. A number of studies have been performed in the pre-antibiotic era, enrolling patients with neurosyphilis and gonococcal infections, with reported cure rates at around 60%–80%. We have outlined the potential molecular and immunological mechanisms explaining the possible beneficial effects of therapeutic hyperthermia. For some pathogens increased temperature exerts a direct negative effect on virulence; however, it is presumed that temperature driven activation of the immune system is probably the most important factor affecting microbial viability. Lastly, we performed a review of modern-era studies where modulation of body temperature has been used as a treatment strategy. In trials of therapeutic hypothermia in patients with infection worse outcomes have been observed in the hypothermia group. Use of antipyretics has not been associated with any improvement in clinical outcomes. In modern-era therapeutic hyperthermia achieved by physical warming has been studied in one pilot trial, and better survival was observed in the hyperthermia group. To conclude, currently there is not enough data to support the use of therapeutic hyperthermia outside clinical trials; however, available studies are in favor of at least a temperature tolerance strategy for non-neurocritical patients.

Leptospirosis is an ubiquitous zoonosis with significant morbidity and mortality. Approximately 10 percent of human infections evolve into a severe form, with a sepsis-like disease, multiorgan failure, and significant mortality rate. The cornerstone of treatment of severe disease is antibiotic therapy, with the aims of preventing complications, reducing the duration of disease, and ultimately reducing mortality. The initiation of antibiotic chemotherapy can precipitate a febrile inflammatory reaction, also known as a Jarisch–Herxheimer reaction. We present a case report of a patient with severe leptospirosis, complicated by multiorgan failure with severe circulatory failure of distributive and cardiogenic etiology, possibly as a consequence of the Jarisch–Herxheimer reaction. The patient was treated with antimicrobial therapy and other supportive measures along with high-dose corticosteroid therapy, long-term mechanical ventilation, high-dose vasopressor therapy, and continuous veno-venous hemodiafiltration with extracorporeal cytokine removal.With this case, we would like to report on a patient presenting with two neglected diseases in our part of Europe, who was treated with novel therapeutic strategies.

Our core body temperature is held around 37 ∘ C by an effective internal thermoregulatory system. However, various clinical scenarios have a more favorable outcome under external temperature regulation. Therapeutic hypothermia, for example, was found beneficial for the outcome of resuscitated cardiac arrest patients due to its protection against cerebral ischemia. Nonetheless, practice shows that outcomes of targeted temperature management vary considerably in dependence on individual tissue damage levels and differences in therapeutic strategies and protocols. Here, we address these differences in detail by means of computational modeling. We develop a multi-segment and multi-node thermoregulatory model that takes into account details related to specific post-cardiac arrest-related conditions, such as thermal imbalances due to sedation and anesthesia, increased metabolic rates induced by inflammatory processes, and various external cooling techniques. In our simulations, we track the evolution of the body temperature in patients subjected to post-resuscitation care, with particular emphasis on temperature regulation via an esophageal heat transfer device, on the examination of the alternative gastric cooling with ice slurry, and on how anesthesia and the level of inflammatory response influence thermal behavior. Our research provides a better understanding of the heat transfer processes and therapies used in post-cardiac arrest patients. [ABSTRACT FROM AUTHOR]

Background and Objectives: Insertion of an intraosseous access device enables intravascular access for critically ill patients in a prehospital and emergency department setting even when intravenous access is not possible. The aim of our study was to assess the attitudes of prehospital and emergency department nursing staff towards the utilization of intraosseous access devices. Materials and Methods: We performed quantitative research using a closed-ended structured questionnaire distributed to prehospital unit and associated emergency department nursing staff serving a population of around 200,000 inhabitants. Results: We distributed 140 questionnaires, and 106 were returned and completed. Of these, 69 (65.1%) respondents needed more than three attempts to achieve peripheral intravenous access at least once in the last year and 29 (27.4%) required central venous access because of impossible intravenous access. In the last five years, 8 (7.5%) respondents used endotracheal route for administration of medications. Despite this, only 48 (45.3%) of respondents have ever used the intraosseous route. Also, 79 (74.5%) respondents received at least some training in obtaining IO access; however, 46 (43.4%) answered that education regarding intraosseous access is not sufficient, and 92 (86.8%) answered that they wanted additional training regarding intraosseous access. Conclusions: Prehospital and emergency department nursing staff are aware of the importance of intraosseous access and understand the need for additional education and certification in this field.

Background: Air pollution with increased concentrations of fine (< 2.5 μm) particulate matter (PM2.5) increases the risk of cardiovascular morbidity and mortality. Even short-term increase of PM2.5 may help trigger ST-elevation myocardial infarction (STEMI) and heart failure (HF) in susceptible individuals, even in areas with good air quality. Purpose: To evaluate the role of PM2.5 levels ≥ 20 μg/m3 in admission acute HF in STEMI patients. Materials and Methods: In 290 STEMI patients with the leading reperfusion strategy primary percutaneous coronary intervention (PPCI), we retrospectively studied independent predictors of admission acute HF and included admission demographic and clinical data as well as ambient PM2.5 levels ≥ 20 μg/m3. We defined admission acute HF in STEMI patients as classes II–IV by Killip Kimball classification. Results: Acute admission HF was observed in 34.5% of STEMI patients. PPCI was performed in 87.1% of acute admission HF patients and in 94.7% non-HF patients (p= 0.037). Significant independent predictors of acute admission HF were prior diabetes (OR 2.440, 95% CI 1.100 to 5.400, p=0.028), admission LBBB (OR 10.190, 95% CI 1.160 to 89.360, p=0.036), prior resuscitation (OR 2.530, 95% CI 1.010 to 6.340, p=0.048), admission troponin I≥ 5μg/l (OR 3.390, 95% CI 1.740 to 6.620, p< 0.001), admission eGFR levels (0.61, 95% CI 0.52 to 0.72, p < 0.001), and levels of PM2.5 ≥ 20 μg/m3 (OR 2.140, 95% CI 1.005 to 4.560, p=0.049) one day before admission. Conclusion: Temporary short-term increase in PM2.5 levels (≥ 20 μg/m3) one day prior to admission in an area with mainly good air quality was among significant independent predictors of acute admission HF in STEMI patients.

Background. Mortality of admitted out-of-hospital cardiac arrest (OHCA) patients is decreasing. Our aim was to evaluate independent predictors of six-month mortality of successfully resuscitated OHCA patients. Methods. We reviewed retrospectively the records of 119 OHCA patients, admitted in 2011 to 2013 (73.1% men, mean age 64 ± 13,5 years) and registered their clinical data, treatments, and predictors of 6-month mortality. Results. Six-month mortality of admitted OHCA patients was 47.5% and was associated significantly with older age (67.7 ± 12.9 years versus 59.9 ± 13 years, p<0.05), mechanical ventilation, longer time of resuscitation (24.6 ± 18.9 sec versus 8.9 ± 8.4 sec, p<0.05), use of vasopressors (87.3% versus 62.5%, p<0.05), and increased serum lactate (8.1 ± 3.9 mmol/l versus 4.5 ± 3.6 mmol/l, p<0.05) but less likely with prior shockable rhythm (38% versus 73.2%, p<0.05), percutaneous coronary intervention (27% versus 55.4%, p<0.05), achieved target temperatures 32°–34°C of mild therapeutic hypothermia (47.6% versus 71.4%, p<0.05), acute coronary syndromes (31.7% versus 51.8%, p<0.05), and neurological recovery (4.8% versus 69.6%, p<0.05) when compared to survivors. Neurological outcome was most significant early independent predictor of 6-month mortality (OR 50.47; 95% CI 6.74 to 377.68; p<0.001). Conclusions. Postcardiac arrest brain injury most significantly and independently predicted 6-month mortality in hospitalized OHCA patients. [ABSTRACT FROM AUTHOR]

Background: A decade ago women with ST-elevation myocardial infarction (STEMI) were significantly older than men, with more comorbidities, less likely treated by primary percutaneous coronary intervention (PPCI) and their prognosis was worse. The progress in treatment led to increased survival after STEMI. Our aim was to evaluate the possible current differences between the genders in treatments, mortality and the changes in women over time in STEMI population. Methods: We retrospectively evaluated 307 STEMI patients (224 men, 83 women), admitted between October 1, 2011 and December 31, 2012 and a historic group of 523 STEMI patients from 2008 to 2009 (361 men, 162 women). Reperfusion strategy was PPCI, combined with aspirin and clopidogrel or prasugrel or ticagrelor and a heparin with glycoprotein receptor IIb/IIIa antagonist or bivalirudin. Between the genders and in women over time we compared clinical data, the use and time to PPCI, in-hospital complications, 30-day and 6-month mortality. Results: STEMI patients in recent years were treated by PPCI in 94.5 %. Their 30-day mortality was 10.4 % and 6-month mortality 14.7 %. Between the genders we observed mostly nonsignificant differences (age, comorbidities, treatments, in-hospital complications, 30-day and 6-month mortality). Over the last years in women mean age significantly decreased, the use of PPCI significantly increased, the incidence of heart failure and bleedings decreased significantly, but mortalities nonsignificantly. Conclusion: Women still account for 1/4 of STEMI population, but the gap between the genders in presentation, treatments and outcome in STEMI population is decreasing. [ABSTRACT FROM AUTHOR]

In patients with refractory cardiac arrest presumably from acute coronary occlusion, primary percutaneous coronary intervention (PPCI) may provide an opportunity for revascularisation and, subsequently, return of spontaneous circulation. We present our experience from a 24/7 primary percutaneous coronary intervention centre serving a population of approximately 800,000 individuals. A retrospective analysis was performed in patients with cardiac arrest treated from July 2011 to January 2014. Inclusion criteria were cardiac arrest and emergency coronary angiography performed during on-going external cardiopulmonary resuscitation (CPR). Course of treatment was analysed to outline the reasons for poor survival. Eight patients met the inclusion criteria; six (75 %) were male, and the mean age was 63 ± 16 years. Revascularisation under continuous cardiopulmonary resuscitation was achieved in all eight patients. Sustained return of spontaneous circulation was achieved in two patients (25 %). Both patients had poor neurological outcome (cerebral performance category 4), and both died within 3 months. We identified total duration of cardiopulmonary resuscitation (90.5 ± 33.3 min), lack of prehospital mechanical cardiopulmonary resuscitation devices and lack of extra-corporeal life support devices as the most likely reasons contributing to poor survival.

Some patients who need dual antiplatelet therapy sometimes require tracheotomy. Aim of this study was to compare the rate of complications during and after surgical tracheotomy between patients requiring dual antiplatelet therapy and those without dual antiplatelet therapy. We retrospectively included 79 patients (62% men, mean age 64 ± 14 years) in the period 2007- 2011. The following complications were analyzed: need for surgical revision within 24 hours after tracheotomy, need for bronchoscopy within 24 hour after tracheotomy, need for blood transfusion within 24 hours after tracheotomy, death attributed to tracheotomy and any complication attributed to tracheotomy. We compared patients where tracheotomy was performed while receiving dual antiplatelet therapy (n=27, 34%) to patients where tracheotomy was performed without dual antiplatelet therapy (n=52, 66%). Nonsignificant differences between the two groups were observed general characteristics. There were no statistically significant differences in complications after tracheotomy (surgical revision after tracheotomy p=0.63, bronchoscopy after tracheotomy p=0.74, blood transfusion after tracheotomy p=0.59, death attributed to tracheotomy p=1.00 and any complication attributed to tracheotomy p=1.00). The study shows that tracheotomy is safe in cardiac patients on dual antiplatelet therapy. [ABSTRACT FROM AUTHOR]

The need for temperature modulation (mostly cooling) in critically ill patients is based on the expected benefits associated with decreased metabolic demands. However, evidence-based guidelines for temperature management in a majority of critically ill patients with fever are still lacking. The aim of our retrospective single-site observational study was to determine the differences in ICU treatment between patients in whom their temperature remained within the target temperature range for ≥25% of time (inTT group) and patients in whom their temperature was outside the target temperature range for <24% of time (outTT group). We enrolled 76 patients undergoing invasive mechanical ventilation for respiratory failure associated with sepsis. We observed no significant differences in survival, mechanical ventilation settings and duration, vasopressor support, renal replacement therapy and other parameters of treatment. Patients in the inTT group were significantly more frequently cooled with the esophageal cooling device, received a significantly lower cumulative dose of acetaminophen and significantly more frequently developed a presence of multidrug-resistant pathogens. In our study, achieving a better temperature control was not associated with any improvement in treatment parameters during ICU stay. A lower prevalence of multidrug-resistant pathogens in patients with higher body temperatures opens a question of a pro-pyrexia approach with an aim to achieve better patient outcomes.

The treatment of quetiapine and/or citalopram poisoning is mainly supportive and involves gastric lavage, activated charcoal, intubation, and mechanical ventilation. Recently, however, there were reports of successful treatment with intravenous lipid emulsion. Here we report a case of a 19-year-old Caucasian girl who ingested approximately 6000 mg of quetiapine, 400 mg of citalopram, and 45 mg of bromazepam in a suicide attempt. The patient developed ventricular tachycardia and epileptic seizures 12 h after admission to the hospital. As the patient's condition deteriorated, we combined standard therapy (intubation, mechanical ventilation, and vasopressors) with low-dose intravenous lipid emulsion (ILE) (a total of 300 mL of 20 % lipid emulsion) and normalised her heart rhythm and stopped the seizures. She was discharged to the psychiatric ward after 48 h and home after a prolonged (2-month) psychiatric rehabilitation. Intravenous lipid emulsion turned out to be effective even in the lower dose range than previously reported for quetiapine poisoning in patients presenting with seizure and ventricular arrhythmia. To our knowledge, there are no case reports describing the use of ILE in treating citalopram poisoning. [ABSTRACT FROM AUTHOR]

Various mobile phone apps in the form of medical calculators are available for different prognostic assessments, especially for patients in intensive care units. We performed a systematic review of mobile phone apps in online mobile phone stores to identify apps for mortality risk prediction in intensive care units. Out of 2737 potential mobile phone apps, we included 20 of them in the final content analysis. The most frequently used mortality risk model was Sequential Organ Failure Assessment also known as SOFA. The mobile phone apps were compared based on realistic electronic medical record data. The discrepancies were shown in patients with lower mortality rate. Our results show that this kind of mobile phone apps can be helpful to healthcare professionals and are appropriate for use in clinical practices in most cases. [ABSTRACT FROM AUTHOR]

Introduction: The rapid use of an automated external defibrillator (AED) is crucial for increased survival after an out-of-hospital cardiac arrest (OHCA). Many factors could play a role in limiting the chance of an AED use. We aimed to verify the situation regarding AED legislation, the AED mapping system and first responders (FRs) equipped with an AED across European countries. Methods: We performed a survey across Europe entitled "European Study about AED Use by Lay Rescuers" (ENSURE), asking the national coordinators of the European Registry of Cardiac Arrest (EuReCa) program to complete it. Results: Nineteen European countries replied to the survey request for a population covering 128,297,955 inhabitants. The results revealed that every citizen can use an AED in 15 countries whereas a training certificate was required in three countries. In one country, only EMS personnel were allowed to use an AED. An AED mapping system and FRs equipped with an AED were available in only 11 countries. The AED use rate was 12–59% where AED mapping and FR systems were implemented, which was considerably higher than in other countries (0–7.9%), reflecting the difference in OHCA survival. Conclusions: Our survey highlighted a heterogeneity in AED legislation, AED mapping systems and AED use in Europe, which was reflected in different AED use and survival. [ABSTRACT FROM AUTHOR]

Background: Septic cardiomyopathy represents cardiac impairment in sepsis and is a part of systemic involvement in sepsis. Cytokine storm is responsible for septic shock and for myocardial dysfunction of potentially reversible septic cardiomyopathy. Several case reports and case series demonstrated successful removal of circulating cytokines by combined blood purification techniques. In this way, septic shock and survival of septic patients improved. However, the evidences for reversal of myocardial dysfunction are rare.Case Presentation: We present a patient with a history of chemotherapy for coat cell lymphoma, splenectomy and autologous bone marrow transplantation, who suffered severe pneumococcal sepsis, septic shock and septic cardiomyopathy, resistant to pharmacological therapy. Combined blood purification techniques 36 h after the start of treatment successfully decreased Interleukin-6 level, lactacidosis, the need for vasopressors to maintain normotension, improved systolic function of the left ventricle and clinical outcome.Conclusions: Our case suggests that combined blood purification techniques initiated even 36 h after the start of treatment successfully removed inflammatory cytokines, reversed circulatory failure and improved left ventricular systolic function in pneumococcal sepsis.

Purpose: Mortality is high in survivors of out-of-hospital cardiac arrest (OHCA) -- it is even up to 86% and it strongly correlates with ischemic brain damage. In the last decade, quality of cardiopulmonary resuscitation by emergency medical services (EMS) enormously improved as well as the postcardiac arrest treatment of survivors of OHCA in intensive care units, in particular by introducing mild induced therapeutic hypothermia to prevent ischemic brain injury. Our purpose was to evaluate 30-day mortality and neurological outcome in survivors of OHCA. Methods: We retrospectively studied 119 survivors of OHCA (73.1% men, mean age 64.1±13.5), admitted from 2011 to 2013. On admission, they were comatose with palpable pulse, breathing either spontaneously or mechanically ventilated. Postcardiac arrest treatment included iv. infusion of fluids, vasopressors and inotropes if necessary, percutaneous coronary interventions (PCI) in case of acute coronary syndromes (ACS), mild induced hypothermia of 34°C for the first 24 hours. Neurological evaluation by cerebral performance category (CPC) scale 1-5 was performed. Mild to moderate neurological disability was registered as CPC scale 1-2, severe cerebral disability, vegetative state and brain death as CPC scale 3-5. Results: OHCA was witnessed in 45.4%. It was the consequence of ventricular fibrillation or pulseless ventricular tachicardia (VF/VT) in 54.6% and of asystole or pulseless electrical activity (PEA) in 45.6%. Mean time from OHCA to EMS arrival was 8.6±4.5 minutes, mean time from EMS arrival to return of spontaneous circulation (ROSC) due to resuscitation by EMS 17.6±17 minutes. On arrival to intensive care, the patients were comatose, 92.4% mechanically ventilated. Mild therapeutic hypothermia was performed in 82.4% during the first 24 hours. Mean admission troponin I level was 6.5±20.8 µg/l, admission lactate 6.5±4.2 mmol/l and peak troponin I 35.3±4.8 µg/l. ACS were the cause for 41.1% of OHCA. PCIs were performed in 40.3% after emergency coronary angiography. Mean ejection fraction within the first few hours was 33.7±15%. Vasopressors were administered in 75.6%, inotropes in 57.1%, intraaortic baloon pump in 6.7%. 30-day mortality was 46.2% and 6-month mortality 52.9%. CPC scale 1-2 was achieved in 35.3%, CPC scale 3-5 in 64.7%. Conclusion: Improvements in resuscitation and postresuscitation care resulted in an increased survival and better neurological outcome of successfully resuscitated patients due to OHCA.
