- Abstract
Background: The Hypotension Prediction Index is designed to predict intraoperative hypotension in a timely manner and is based on arterial waveform analysis using machine learning. It has recently been suggested that this algorithm is highly correlated with the mean arterial pressure itself. Therefore, the aim of this study was to compare the index with mean arterial pressure-based prediction methods, and it is hypothesized that their ability to predict hypotension is comparable., Methods: In this observational study, the Hypotension Prediction Index was used in addition to routine intraoperative monitoring during moderate- to high-risk elective noncardiac surgery. The agreement in time between the default Hypotension Prediction Index alarm (greater than 85) and different concurrent mean arterial pressure thresholds was evaluated. Additionally, the predictive performance of the index and different mean arterial pressure-based methods were assessed within 5, 10, and 15 min before hypotension occurred., Results: A total of 100 patients were included. A mean arterial pressure threshold of 73 mmHg agreed 97% of the time with the default index alarm, whereas a mean arterial pressure threshold of 72 mmHg had the most comparable predictive performance. The areas under the receiver operating characteristic curve of the Hypotension Prediction Index (0.89 [0.88 to 0.89]) and concurrent mean arterial pressure (0.88 [0.88 to 0.89]) were almost identical for predicting hypotension within 5 min, outperforming both linearly extrapolated mean arterial pressure (0.85 [0.84 to 0.85]) and delta mean arterial pressure (0.66 [0.65 to 0.67]). The positive predictive value was 31.9 (31.3 to 32.6)% for the default index alarm and 32.9 (32.2 to 33.6)% for a mean arterial pressure threshold of 72 mmHg., Conclusions: In clinical practice, the Hypotension Prediction Index alarms are highly similar to those derived from mean arterial pressure, which implies that the machine learning algorithm could be substituted by an alarm based on a mean arterial pressure threshold set at 72 or 73 mmHg. Further research on intraoperative hypotension prediction should therefore include comparison with mean arterial pressure-based alarms and related effects on patient outcome., (Copyright © 2024 American Society of Anesthesiologists.

- Abstract
We describe and assess the efficiency of a novel technique of placing implantable collamer lens (ICL) footplates in the sulcus in poorly dilated pupils utilizing perioptic holes and two instruments simultaneously (Sinskey hook and ICL manipulator). Twelve eyes of 10 patients underwent ICL implantation through this technique. The technique employs a bimanual approach engaging perioptic holes in the eyes with intraoperative miosis. Perioptic holes were engaged with a Sinskey hook and pulled slightly back, while the footplates were tucked under the iris by using an ICL manipulator. All patients had uneventful surgery. At 1 week follow-up, uncorrected distance visual acuity (UCDVA) was -0.01 ± 0.04 logMAR with a mean vault of 606.17 ± 108.33 microns. No complications were noted. However, too small a pupil is a limiting factor; this technique can be of use in up to mid-dilated pupils. Bimanual placement of haptics of ICL may represent a safe and effective technique in insufficient mydriasis or intraoperative pupillary miosis., (Copyright © 2024 Copyright: © 2024 Indian Journal of Ophthalmology.)

- Abstract
Abstract: This review discusses the grading of cholecystitis, the optimal timing of cholecystectomy, adopting a culture of safe cholecystectomy, understanding the common error traps that can lead to intraoperative complications, and how to avoid them. 1-28 The Tokyo Guidelines, American Association for the Surgery of Trauma, Nassar, and Parkland scoring systems are discussed. The patient factors, physiologic status, and operative findings that predict a difficult cholecystectomy or conversion from laparoscopic to open cholecystectomy are reviewed. With laparoscopic expertise and patient conditions that are not prohibitive, early laparoscopic cholecystectomy is recommended. This is ideally within 72 hours of admission but supported up to the seventh hospital day. The majority of bile duct injuries are due to misidentification of normal anatomy. Strasberg's four error traps and the zones of danger to avoid during a cholecystectomy are described. The review emphasizes the importance of a true critical view of safety for identification of the anatomy. In up to 15% of operations for acute cholecystitis, a critical view of safety cannot be achieved safely. Recognizing these conditions and changing your operative strategy are mandatory to avoid harm. The principles to follow for a safe cholecystectomy are discussed in detail. The cardinal message of this review is, "under challenging conditions, bile duct injuries can be minimized via either a subtotal cholecystectomy or top-down cholecystectomy if dissection in the hepatocystic triangle is avoided". 21 The most severe biliary/vascular injuries usually occur after conversion from laparoscopic cholecystectomy. Indications and techniques for bailout procedures including the fenestrating and reconstituting subtotal cholecystectomy are presented. Seven percent to 10% of cholecystectomies for acute cholecystitis currently result in subtotal cholecystectomy. Level of evidence: III., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Competing Interests: Disclosure All authors disclosed no financial relationships. Commentary Albeit rare, injury to the diaphragm during POEM can have devastating consequences, and every effort should be taken to prevent injury to the diaphragm. These authors demonstrate an interesting case of inadvertent superficial injury of the diaphragm during posterior myotomy. The case highlights the importance of identifying both the circular and the longitudinal muscles during POEM, with careful selective myotomy of both these layers. In addition, performing myotomy using an outward-in approach instead of an in-outward approach can help preserve the extraluminal adventitia and avoid inadvertent injury to the surrounding organs, such as the pericardium or diaphragm. Thus, during an anterior approach, myotomy in a top-down fashion is preferred, whereas during a posterior myotomy, a down-top myotomy can be helpful.

- Abstract
Purpose of Review: Increasing uptake of gender affirming surgery has allowed for a wider breadth of publication examining complications associated with vaginoplasty. This review aims to provide a comprehensive overview of complications associated with vaginoplasty procedures, focusing on intraoperative, early postoperative, and delayed postoperative complications across different surgical techniques., Recent Findings: Intraoperative complications such as bleeding, injury of the rectum, urethra and prostate, and intra-abdominal injury are discussed, with insights into their incidence rates and management strategies. Early postoperative complications, including wound dehiscence, infection, and voiding dysfunction, are highlighted alongside their respective treatment approaches. Moreover, delayed postoperative complications such as neovaginal stenosis, vaginal depth reduction, vaginal prolapse, rectovaginal fistula, and urinary tract fistulas are assessed, with a focus on their etiology, incidence rates, and management options., Summary: Vaginoplasty complications range from minor wound issues to severe functional problems, necessitating a nuanced understanding of their management. Patient counseling, surgical approach, and postoperative care optimization emerge as crucial strategies in mitigating the impact of complications. Standardizing complication reporting and further research are emphasized to develop evidence-based strategies for complication prevention and management in vaginoplasty procedures., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Background: There is a lack of robust evidence to recommend the use of perioperative ureteric catheterisation or stenting in complex gynaecological surgery., Objectives: To evaluate the evidence on the benefits and risks of perioperative ureteric catheterisation or stenting in complex gynaecological surgery., Search Strategy: A literature search was performed in CINAHL, the Cochrane Library, Embase and MEDLINE, from 1946 to January 2024, using a combination of keywords and Medical Subject Headings (MeSH) terminology., Selection Criteria: Randomised controlled trials (RCTs) and observational studies were included., Data Collection and Analysis: Meta-analysis of the RCTs and observational studies were performed separately. Cochrane RevMan 6.5.1 was used to undertake meta-analysis. Risk ratios with 95% CIs were calculated for the outcome measures., Main Results: Ten studies were included: three RCTs and seven observational studies, comprising 8661 patients. The three RCTs, comprising a total of 3277 patients, showed no difference in the risk of immediate complications in the form of ureteric injury between the ureteric stent and the control groups (RR 0.9, 95% CI 0.49-1.65). The observational studies included 5384 patients. Four studies that explored the ureteric injury as an outcome did not show any difference between the two groups (RR 0.76, 95% CI 0.27-2.16). One case-control study with 862 participants found that the rate of ureteric injury was higher in the non-stented group, although this was observed in only three patients. The risk of urinary tract infection (UTI) was increased in the stent group, although not with statistical significance (RR 1.84, 95% CI 0.47-7.17). There was no significant difference in the risk of ureteric fistulae (RR 1.91, 95% CI 0.62-5.83), although the number of studies was limited., Conclusions: Prophylactic ureteric catheterisation or stenting for complex gynaecological surgery is not associated with a lower risk of ureteric injury., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Purpose: Laparoscopic cholecystectomy, introduced in 1985 by Prof. Dr. Erich Mühe, has become the gold standard for treating chronic symptomatic calculous cholecystopathy and acute cholecystitis, with an estimated 750,000 procedures performed annually in the United States of America. The risk of iatrogenic bile duct injury persists, ranging from 0.2 to 1.3%. Risk factors include male gender, obesity, acute cholecystitis, previous hepatobiliary surgery, and anatomical variations in Calot's triangle. Strategies to mitigate bile duct injury include the Critical View of Safety and fundus-first dissection, along with intraoperative cholangiography and alternative approaches like subtotal cholecystectomy., Methods: This paper introduces the shoeshine technique, a maneuver designed to achieve atraumatic exposure of anatomical structures, local hemostatic control, and ease of infundibulum mobilization. This technique involves the use of a blunt dissection tool and gauze to create traction and enhance visibility in Calot's triangle, particularly beneficial in cases of severe inflammation. Steps include using the critical view of safety and Rouviere's sulcus line for orientation, followed by careful dissection and traction with gauze to maintain stability and reduce the risk of instrument slippage., Results: The technique, routinely used by the authors in over 2000 cases, has shown to enhance patient safety and reduce bile duct injury risks., Conclusion: The shoeshine technique represents a simple and easy way to apply maneuver that can help surgeon during laparoscopic cholecystectomies exposing the hepatocystic area and promote blunt dissection.

- Abstract
Intraoperative hypotension (IOH) is a common issue associated with acute kidney injury, myocardial injury, stroke, and death. IOH may be avoided with the incorporation of newer advanced hemodynamic monitoring technologies. This case study examines the use of advanced hemodynamic monitoring with an early warning system for the intraoperative hemodynamic management of a patient presenting for pancreaticoduodenectomy. Incorporating the hypotension prediction index and other hemodynamic parameters to anticipate impending hypotension and treat potential causative factors is an emerging technological advancement. Understanding and embracing the potential for new advanced hemodynamic technology to reduce intraoperative hypotension's severity, duration, and occurrence is key to reducing negative patient outcomes., Competing Interests: Name: Amy Yerdon, DNP, CRNA, CNE, CHSE Contribution: This author made significant contributions to the conception, synthesis, writing, and final editing and approval of the manuscript to justify inclusion as an author; she is the corresponding author of this article.

- Abstract
Objective: To determine if subepidermal moisture (SEM) measures help detect and prevent intraoperative acquired pressure injuries (IAPIs) for prone-position surgery., Methods: In this clinical trial of patients (n = 39 preintervention, n = 48 intervention, 100 historical control) undergoing prone-position surgery, researchers examined the use of multidimensionally flexible silicone foam (MFSF) dressings applied preoperatively to patients' face, chest, and iliac crests. Visual skin assessments and SEM measures were obtained preoperatively, postoperatively, and daily for up to 5 days or until discharge. Electronic health record review included demographic, medical, and surgery data., Results: Of the 187 total participants, 76 (41%) were women. Participants' mean age was 61.0 ± 15.0 years, and 9.6% were Hispanic (n = 18), 9.6% were Asian (n = 18), 6.9% were Black or African American (n = 13), and 73.8% were White (n = 138). Participants had a mean Scott-Triggers IAPI risk score of 1.5 ± 1.1. Among those with no erythema preoperatively, fewer intervention participants exhibited postoperative erythema on their face and chest than did preintervention participants. Further, fewer intervention participants had SEM-defined IAPIs at all locations in comparison with preintervention participants. The MFSF dressings overcame IAPI risk factors of surgery length, skin tone, and body mass index with fewer IAPIs in intervention participants., Conclusions: Patients undergoing prone-position surgeries developed fewer IAPIs, and SEM measures indicated no damage when MFSF dressings were applied to sites preoperatively. The SEM measures detected more damage than visual assessment., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Purpose: Maintaining hemodynamic stability during cardiac ablation under general anesthesia is challenging. Remimazolam, a novel ultrashort-acting benzodiazepine, is characterized by maintaining comparatively stable blood pressure and does not influence the cardiac conduction system, which renders it a reasonable choice for general anesthesia for cardiac ablation. We aimed to evaluate whether remimazolam is associated with a decreased incidence of intraoperative hypotension compared with desflurane., Methods: In this single-centre, parallel-group, prospective, single-blind, randomized clinical trial, we randomized patients (1:1) into a remimazolam group (remimazolam-based total intravenous anesthesia) or desflurane group (propofol-induced and desflurane-maintained inhalational anesthesia) during cardiac ablation procedures for arrhythmia. The primary outcome was the incidence of intraoperative hypotensive events, defined as mean arterial pressure of < 60 mm Hg at any period., Results: Overall, we enrolled 96 patients between 2 August 2022 and 19 May 2023 (47 and 49 patients in the remimazolam and desflurane groups, respectively). The remimazolam group showed a significantly lower incidence of hypotensive events (14/47, 30%) than the desflurane group (29/49, 59%; relative risk [RR], 0.5; 95% confidence interval [CI], 0.31 to 0.83; P = 0.004). Remimazolam was associated with a lower requirement for bolus or continuous vasopressor infusion than desflurane was (23/47, 49% vs 43/49, 88%; RR, 0.56; 95% CI, 0.41 to 0.76; P < 0.001). No between-group differences existed in the incidence of perioperative complications such as nausea, vomiting, oxygen desaturation, delayed emergence, or pain., Conclusions: Remimazolam was a viable option for general anesthesia for cardiac ablation. Remimazolam-based total intravenous anesthesia was associated with significantly fewer hypotensive events and vasopressor requirements than desflurane-based inhalational anesthesia was, without significantly more complications., Study Registration: ClinicalTrials.gov (NCT05486377); first submitted 1 August 2022., (© 2024.

- Abstract
Introduction: Intraoperative goal-directed hemodynamic therapy (GDHT) is a cornerstone of enhanced recovery protocols. We hypothesized that use of an advanced noninvasive intraoperative hemodynamic monitoring system to guide GDHT may decrease intraoperative hypotension (IOH) and improve perfusion during pancreatic resection., Methods: The monitor uses machine learning to produce the Hypotension Prediction Index to predict hypotensive episodes. A clinical decision-making algorithm uses the Hypotension Prediction Index and hemodynamic data to guide intraoperative fluid versus pressor management. Pre-implementation (PRE), patients were placed on the monitor and managed per usual. Post-implementation (POST), anesthesia teams were educated on the algorithm and asked to use the GDHT guidelines. Hemodynamic data points were collected every 20 s (8942 PRE and 26,638 POST measurements). We compared IOH (mean arterial pressure <65 mmHg), cardiac index >2, and stroke volume variation <12 between the two groups., Results: 10 patients were in the PRE and 24 in the POST groups. In the POST group, there were fewer minimally invasive resections (4.2% versus 30.0%, P = 0.07), more pancreaticoduodenectomies (75.0% versus 20.0%, P < 0.01), and longer operative times (329.0 + 108.2 min versus 225.1 + 92.8 min, P = 0.01). After implementation, hemodynamic parameters improved. There was a 33.3% reduction in IOH (5.2% ± 0.1% versus 7.8% ± 0.3%, P < 0.01, a 31.6% increase in cardiac index >2.0 (83.7% + 0.2% versus 63.6% + 0.5%, P < 0.01), and a 37.6% increase in stroke volume variation <12 (73.2% + 0.3% versus 53.2% + 0.5%, P < 0.01)., Conclusions: Advanced intraoperative hemodynamic monitoring to predict IOH combined with a clinical decision-making tree for GDHT may improve intraoperative hemodynamic parameters during pancreatectomy. This warrants further investigation in larger studies., (Copyright © 2024 Elsevier Inc. All rights reserved.)

- Abstract
Arterial pressure monitoring and management are mainstays of haemodynamic therapy in patients having surgery. This article presents updated consensus statements and recommendations on perioperative arterial pressure management developed during the 11th POQI PeriOperative Quality Initiative (POQI) consensus conference held in London, UK, on June 4-6, 2023, which included a diverse group of international experts. Based on a modified Delphi approach, we recommend keeping intraoperative mean arterial pressure ≥60 mm Hg in at-risk patients. We further recommend increasing mean arterial pressure targets when venous or compartment pressures are elevated and treating hypotension based on presumed underlying causes. When intraoperative hypertension is treated, we recommend doing so carefully to avoid hypotension. Clinicians should consider continuous intraoperative arterial pressure monitoring as it can help reduce the severity and duration of hypotension compared to intermittent arterial pressure monitoring. Postoperative hypotension is often unrecognised and might be more important than intraoperative hypotension because it is often prolonged and untreated. Future research should focus on identifying patient-specific and organ-specific hypotension harm thresholds and optimal treatment strategies for intraoperative hypotension including choice of vasopressors. Research is also needed to guide monitoring and management strategies for recognising, preventing, and treating postoperative hypotension., (Copyright © 2024 The Author(s).

- Abstract
Objective: To explore the effectiveness and safety of the extreme flexion and abduction hip combined with a stirrup-shaped multifunctional leg frame position in preventing obturator nerve reflex during plasma resection of bladder tumors (TUR-BT)., Methods: A total of 112 patients with bladder tumors were included in the study. The control group was placed in a lithotomy position, while the experimental group was placed in an extreme flexion and abduction hip combined with a stirrup-shaped multifunctional leg frame position. The grade of leg jerking, operation time, and some operative complications were compared between groups., Results: The operation time, bleeding volume, the grade of leg jerking, second TUR-BT, and acquisition of detrusor muscle were significantly better in the experimental group compared to the control group (P = 0.018, P = 0.013, P < 0.001, P = 0.041, and P < 0.001, respectively). The grade of leg jerking in the experimental group was extremely low (distributed in grade 1 and 2), and there were no severe reactions in grade 3 and 4., Conclusion: The extreme flexion and abduction hip combined with a stirrup-shaped multifunctional leg frame position for TUR-BT is a safe and effective treatment method that can effectively prevent obturator nerve reflex, reduce complications, improve surgical efficacy, and reduce anesthesia dependence and risk., (© 2024.

- Abstract
Background: Acute posterior sternoclavicular joint injuries are rare but potentially lethal injuries-signs of mediastinal compression range from nonspecific to neurovascular compromise. Currently, orthopaedic experts recommend a cardiothoracic surgeon be placed on standby during open surgery for potential intraoperative complications. However, few studies have reported on how often cardiothoracic intervention is required., Methods: First, we identified patients in our institution by CPT codes 23530, 23525, and 23532 from January 1, 2002 to May 1, 2023. Demographic variables and intraoperative cardiothoracic intervention rates were collected. Second, we systematically reviewed the literature to identify articles on acute posterior sternoclavicular injury using PubMed, Embase, and CINAHL databases (through August 20, 2023). Exclusion criteria included conservative treatment, successful closed reduction, chronic injury (>6 wk) cadaver studies, reviews, and nonavailable text., Results: Thirteen local patients underwent open surgery for an acute posterior sternoclavicular joint injury, 11 males and 2 females with an average age of 18.2 years old (range: 15 to 32.4). The most common mechanism of injury was sports (n=9; 69.2%). Four (30.8%) patients had physical or radiographic evidence of mediastinal compression. No patients required intraoperative cardiothoracic intervention in our institution. The literature search yielded 132 articles and 512 open surgeries for acute posterior sternoclavicular joint injuries. Four patients required intraoperative cardiothoracic intervention, all of whom presented with polytrauma and/or clinical or radiographic signs of neurovascular compromise, giving a combined overall rate of 0.76%., Conclusions: Expert opinion commonly recommends cardiothoracic backup during open surgery for acute posterior sternoclavicular joint injuries. On the basis of our local data and systematic literature review, we found an overall cardiothoracic intervention rate of 0.76%. In the presence of polytrauma and/or findings of neurovascular compromise, we suggest having cardiothoracic surgery on close standby during the procedure. However, a patient with an isolated acute posterior sternoclavicular joint injury and no clinical or radiographic findings of neurovascular compromise does not appear to require a cardiothoracic surgeon on standby. Ultimately, the decision to involve cardiothoracic backup during open surgery for an acute posterior sternoclavicular injury should be made on a case-by-case basis after a thorough physical and radiographic evaluation of the patient., Level of Evidence: Level III., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Background: Accurate recognition of Calot's triangle during cholecystectomy is important in preventing intraoperative and postoperative complications. The use of indocyanine green (ICG) fluorescence imaging has become increasingly prevalent in cholecystectomy procedures. Our study aimed to evaluate the specific effects of ICG-assisted imaging in reducing complications., Materials and Methods: A comprehensive search of databases including PubMed, Web of Science, Europe PMC, and WANFANGH DATA was conducted to identify relevant articles up to July 5, 2023. Review Manager 5.3 software was applied to statistical analysis., Results: Our meta-analysis of 14 studies involving 3576 patients compared the ICG group (1351 patients) to the control group (2225 patients). The ICG group had a lower incidence of postoperative complications (4.78% vs 7.25%; RR .71; 95%CI: .54-.95; P = .02). Bile leakage was significantly reduced in the ICG group (.43% vs 2.02%; RR = .27; 95%CI: .12-.62; I
2 = 0; P = .002), and they also had a lower bile duct drainage rate (24.8% vs 31.8% RR = .64, 95% CI: .44-.91, P = .01). Intraoperative complexes showed no statistically significant difference between the 2 groups (1.16% vs 9.24%; RR .17; 95%CI .03-1.02), but the incidence of intraoperative bleeding is lower in the ICG group., Conclusion: ICG fluorescence imaging-assisted cholecystectomy was associated with a range of benefits, including a lower incidence of postoperative complications, decreased rates of bile leakage, reduced bile duct drainage, fewer intraoperative complications, and reduced intraoperative bleeding., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.- Published

- Abstract
Background and Planning: Intraoperative periprosthetic femoral fractures are among the most serious complications in both primary and revision arthroplasty. They are often not detected, despite intraoperative radiological control. Since an unnoticed intraoperative fracture often requires revision surgery, which has been associated with increased mortality rates, intraoperative diagnosis and corresponding direct and sufficient treatment are crucial. There are patient-, surgery-, and implant-specific risk factors that increase the possibilities of intraoperative fractures. The most common risk factors on the patient side are age, gender, and various pre-existing conditions, such as osteoporosis or rheumatic diseases. A minimally invasive approach and a cementless press-fit fixation are the most significant surgery- and implant-specific risk factors. The Vancouver classification or the modified Mallory classification are available for the classification of intraoperative periprosthetic femoral fractures. Based on these classifications, treatment recommendations can be derived. Different strategies are available for fracture management., Therapy: Generally, if the stem is stable, osteosynthesis can be performed with preservation of the implant. This procedure can be applied to the majority of cases with non-displaced fractures by using cerclages as fixation. An unstable implant may require replacement of the stem. In higher grade fractures, stabilisation by using plate osteosynthesis may be necessary. The aim is to achieve the most anatomical reposition possible for the best possible bony consolidation. The ultimate goal is high implant stability and restoration of the biomechanics., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

- Abstract
Objective: Intraoperative complications of hysteroscopy, such as the creation of a false passage, cervix dilatation failure, and uterine perforation, may require suspension of the procedure. Some patients refuse a new procedure, which delays the diagnosis of a possible serious uterine pathology. For this reason, it is essential to develop strategies to increase the success rate of hysteroscopy. Some authors suggest preoperative use of topical estrogen for postmenopausal patients. This strategy is common in clinical practice, but studies demonstrating its effectiveness are scarce. The aim of this study was to evaluate the effect of cervical preparation with promestriene on the incidence of complications in postmenopausal women undergoing surgical hysteroscopy., Methods: This is a double-blind clinical trial involving 37 postmenopausal patients undergoing surgical hysteroscopy. Participants used promestriene or placebo vaginally daily for 2 weeks and then twice a week for another 2 weeks until surgery., Results: There were 2 out of 14 (14.3%) participants with complications in the promestriene group and 4 out of 23 (17.4%) participants in the placebo group (p=0.593). The complications were difficult cervical dilation, cervical laceration, and vaginal laceration., Conclusion: Cervical preparation with promestriene did not reduce intraoperative complications in postmenopausal patients undergoing surgical hysteroscopy.

- Abstract
Background: Laparoscopic Total Extra-peritoneal Inguinal Hernia Repair(TEP) presents escalated risks of surgical complications, notably bleeding, particularly in European Hernia Society (EHS) types 3 and recurrent inguinal hernia. In this study, we introduced an innovative technique using indocyanine green-labeled fluorescence laparoscopy to mitigate intraoperative complications, including bleeding and rupture of the hernial sac., Methods: This retrospective study reviewed records of 17 patients who underwent TEP repair at Anqing Municipal Hospital between July and August 2023. Intraoperatively, fluorescence imaging was utilized to trace the pathway of the spermatic vessels and outline the boundaries of the hernia sac to facilitate a thorough dissection., Results: The procedure was successfully completed in all 17 patients, with a median operation time of 42 min (range: 30-51 min). Median intraoperative blood loss was 5 ml (range: 3-8 ml). Complete dissection of the hernia sac was achieved in each case without any incidents of sac rupture. Hemodynamic parameters of blood flow within the spermatic artery on postoperative day 1 showed no statistically significant deviations from the preoperative values. Furthermore, during the 7-month follow-up period, there were no cases of seroma formation or hernia recurrence., Conclusion: Our findings suggest that employing indocyanine green-labeled fluorescence technology in TEP repair significantly reduces intraoperative complications, notably bleeding and rupture of the hernial sac. This technique demonstrated a negligible impact on the hemodynamic parameters of the spermatic artery and reduced the overall surgical time., (© 2024. The Author(s).)

- Abstract
Objective: Intraoperative rupture (IOR) is the most common adverse event encountered during surgical clip obliteration of ruptured intracranial aneurysms. Besides increasing surgeon experience and early proximal control, no methods exist to decrease IOR risk. Thus, our objective was to assess if partial endovascular coil embolization to protect the aneurysm before clipping decreases IOR., Methods: We conducted a retrospective analysis of patients with ruptured intracranial aneurysms that were treated with surgical clipping at two tertiary academic centers. We compared patient characteristics and outcomes of those who underwent partial endovascular coil embolization to protect the aneurysm before clipping to those who did not. The primary outcome was IOR. Secondary outcomes were inpatient mortality and discharge destination., Results: We analyzed 100 patients. Partial endovascular aneurysm protection was performed in 27 patients. Age, sex, subarachnoid hemorrhage severity, and aneurysm location were similar between the partially-embolized and non-embolized groups. The median size of the partially-embolized aneurysms was larger (7.0 mm [interquartile range 5.95-8.7] vs. 4.6 mm [3.3-6.0]; P < 0.001). During surgical clipping, IOR occurred less frequently in the partially-embolized aneurysms than non-embolized aneurysms (2/27, 7.4%, vs. 30/73, 41%; P = 0.001). Inpatient mortality was 14.8% (4/27) in patients with partially-embolized aneurysms and 28.8% (21/73) in patients without embolization (P = 0.20). Discharge to home or inpatient rehabilitation was 74.0% in patients with partially-embolized aneurysms and 56.2% in patients without embolization (P = 0.11). A complication from partial embolization occurred in 2/27 (7.4%) patients., Conclusions: Preoperative partial endovascular coil embolization of ruptured aneurysms is associated with a reduced frequency of IOR during definitive treatment with surgical clip obliteration. These results and the impact of preoperative partial endovascular coil embolization on functional outcomes should be confirmed with a randomized trial., (© 2024.

- Abstract
Background: Ureteric injury (UI) is an infrequent but serious complication of colorectal surgery. Prophylactic ureteric stenting is employed to avoid UI, yet its efficacy remains debated. Intraoperative indocyanine green fluorescence imaging (ICG-FI) has been used to facilitate ureter detection. This study aimed to investigate the role of ICG-FI in identification of ureters during colorectal surgery and its impact on the incidence of UI., Methods: A retrospective cohort study involving 556 consecutive patients who underwent colorectal surgery between 2018 and 2023 assessed the utility of routine prophylactic ureteric stenting with adjunctive ICG-FI. Patients with ICG-FI were compared to those without ICG-FI. Demographic data, operative details, and postoperative morbidity were analyzed. Statistical analysis included univariable regression., Results: Ureteric ICG-FI was used in 312 (56.1%) patients, whereas 43.9% were controls. Both groups were comparable in terms of demographics except for a higher prevalence of prior abdominal surgeries in the ICG-FI group. Although intraoperative visualization was significantly higher in the ICG-FI group (95.3% vs 89.1%; p = 0.011), the incidence of UI was similar between groups (0.3% vs 0.8%; p = 0.585). Postoperative complications were similar between the two groups. Median stent insertion time was longer in the ICG-FI group (32 vs 25 min; p = 0.001)., Conclusion: Ureteric ICG-FI improved intraoperative visualization of the ureters but was not associated with a reduced UI rate. Median stent insertion time increased with use of ureteric ICG-FI, but total operative time did not. Despite its limitations, this study is the largest of its kind suggesting that ureteric ICG-FI may be a valuable adjunct to facilitate ureteric visualization during colorectal surgery., (© 2024.

- Abstract
Objective: Identify how surgical team members uniquely contribute to teamwork and adapt their teamwork skills during instances of uncertainty., Background: The importance of surgical teamwork in preventing patient harm is well documented. Yet, little is known about how key roles (nurse, anesthesiologist, surgeon, and medical trainee) uniquely contribute to teamwork during instances of uncertainty, particularly when adapting to and rectifying an intraoperative adverse event (IAE)., Methods: Audiovisual data of 23 laparoscopic cases from a large community teaching hospital were prospectively captured using OR Black Box. Human factors researchers retrospectively coded videos for teamwork skills (backup behavior, coordination, psychological safety, situation assessment, team decision-making, and leadership) by team role under 2 conditions of uncertainty: associated with an IAE versus no IAE. Surgeons identified IAEs., Results: In all, 1015 instances of teamwork skills were observed. Nurses adapted to IAEs by expressing more backup behavior skills (5.3× increase; 13.9 instances/hour during an IAE vs 2.2 instances/hour when no IAE) while surgeons and medical trainees expressed more psychological safety skills (surgeons: 3.6× increase; 30.0 instances/hour vs 6.6 instances/hour and trainees: 6.6× increase; 31.2 instances/hour vs 4.1 instances/hour). All roles expressed fewer situation assessment skills during an IAE versus no IAE., Conclusions: OR Black Box enabled the assessment of critically important details about how team members uniquely contribute during instances of uncertainty. Some teamwork skills were amplified, while others dampened when dealing with IAEs. The knowledge of how each role contributes to teamwork and adapts to IAEs should be used to inform the design of tailored interventions to strengthen interprofessional teamwork., Competing Interests: T.G. has IP ownership and a leadership role in Surgical Safety Technologies Inc.

- Abstract
Purpose: This study evaluates the intraoperative and short-term complications associated with robotically assisted pedicle screw placement in pediatric posterior spinal fusion (PSF) from three surgeons at two different institutions., Methods: We retrospectively reviewed 334 pediatric patients who underwent PSF with robotic-assisted navigation at 2 institutions over 3 years (2020-2022). Five thousand seventy robotically placed screws were evaluated. Data collection focused on intraoperative and early postoperative complications with minimum 30-day follow-up. Patients undergoing revision procedures were excluded., Results: Intraoperative complications included 1 durotomy, 6 patients with neuromonitoring alerts not related to screw placement, and 62 screws (1.2%) with documented pedicle breaches, all of which were revised at time of surgery. By quartile, pedicle breaches statistically declined from first quartile to fourth quartile (1.8% vs. 0.56%, p < 0.05). No breach was associated with neuromonitoring changes or neurological sequelae. No spinal cord or vascular injuries occurred. Seventeen postoperative complications occurred in eleven (3.3%) of patients. There were five (1.5%) patients with unplanned return to the operating room., Conclusion: Robotically assisted pedicle screw placement was safely and reliably performed on pediatric spinal deformity by three surgeons across two centers, demonstrating an acceptable safety profile and low incidence of unplanned return to the operating room., (© 2024.

- Abstract
Background: Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is associated with significant morbidity and mortality. We present an alternative technique that preserves the complete mesenteric vascularization during the isolation of the intestinal segment used in ICUD, including distal vessels. This approach aims to minimize the risk of ischemia in both the ileal anastomosis and the isolated loop at the diversion site., Methods: This cohort study included 31 patients, both male and female, who underwent RARC with ICUD from February 2018 to November 2023, performed by a single surgeon. Intraoperative and postoperative complications data were retrieved for analysis, employing our proposed mesentery-sparing technique in all cases. The primary endpoint was the incidence of intraoperative and postoperative complications directly attributable to the mesentery-sparing approach in ICUD. Secondary endpoints included other postoperative variables not directly related to mesentery preservation, such as the incidence of postoperative ileus requiring parenteral nutrition and the duration of hospitalization., Results: None of the patients experienced intraoperative or postoperative complications directly related to mesentery-sparing, such as intestinal fistulae or internal hernias. The median duration of hospitalization was 6 days, and postoperative ileus necessitating total parenteral nutrition occurred in 19% of the patients. Minor complications (Clavien-Dindo grades I-II) accounted for 27.6% of the cases and major complications (grades III-V) accounted for 20.6%., Conclusion: The mesentery-sparing technique outlined herein offers an alternative method for preserving the vascularization of intestinal segments and reducing the risk of intestinal complications in ICUD during RARC., Competing Interests: None declared., (Copyright® by the International Brazilian Journal of Urology.)

- Abstract
Endometriosis surgery involving the ureter poses significant challenges requiring meticulous surgical techniques and vigilant postoperative care. This chapter addresses key aspects of ureterolysis techniques, intraoperative management of ureteral injuries, and postoperative care in the context of endometriosis surgery. Ureterolysis methods aim to isolate and mobilize the ureter while preserving its vascularity. Cold instruments and careful dissection are recommended to prevent thermal injury during surgery. Intraoperative tools such as indocyanine green (ICG) show promise in assessing for vascular compromise. Over half of ureteral injuries are detected postoperatively, necessitating a high index of suspicion. Optimal postoperative care in the case of ureteral injury involves Foley catheterization for decompression, ureteral stenting, and meticulous follow-ups to monitor healing and renal function. While advances have been made in surgical techniques and diagnostic tools, gaps persist in preoperative imaging optimization and predictive models for identifying at-risk patients. This chapter aims to bridge existing knowledge gaps, optimize surgical practices, and enhance the overall care and outcomes of patients undergoing endometriosis surgery involving the ureter., Competing Interests: Declaration of competing interest L.R.C reports no conflict of interest., (Published by Elsevier Ltd.)

- Abstract
Objective: A cerebellar bulge prior to posterior fossa resection is an emergency condition during surgery. Intraoperative cerebellar bulging not only increases the difficulty of lesion resection but also brings additional postoperative complications. Currently, there are few systematic reports on this topic. The predictors of cerebellar bulge and how to effectively prevent intraoperative cerebellar bulge are discussed in this article., Methods: The clinical and imaging data of 527 patients with posterior fossa lesions who underwent resection at our hospital were retrospectively collected and analyzed. Perioperative clinical and imaging data were assessed. Variables were analyzed using univariate and multivariate regression analyses., Results: Overall, 10.4% (55/527) of patients had intraoperative acute bulges. Multivariate analysis revealed that age <60 years, body mass index ≥24, lesion size ≥30 (mm), cerebellar tonsillar herniation and/or hydrocephalus, and perilesional edema (moderate-severe) were predictors of cerebellar bulging. Relief of the cerebellar bulge can be accomplished by excising the lesion, releasing cerebrospinal fluid, and removing the cerebellum (the outer one-third). Obvious cerebellar-related complications occurred in 4 patients postoperatively, and the symptoms disappeared after 6 months of follow-up., Conclusions: Cerebellar bulging during intraoperative posterior fossa resection deserves attention. Through the analysis of multiple factors related to cerebellar bulge, comprehensive evaluation and early intervention during the perioperative period are necessary. The incidence of cerebellar bulges can be reduced, and surgical complications related to cerebellar bulges can be avoided., (Copyright © 2024 Elsevier Inc. All rights reserved.)

- Abstract
Purpose: To evaluate the safety and efficacy of new staple-line reinforcement (SLR) in pulmonary resection through a prospective study and to compare the results of this study with historical control data in an exploratory study., Methods: The subjects of this study were 48 patients who underwent thoracoscopic lobectomy. The primary endpoint was air leakage from the staple line. The secondary endpoints were the location of air leakage, duration of air leakage, and postoperative pulmonary complications., Results: The incidence of intraoperative air leakage from the staple line was 6.3%. Three patients had prolonged air leakage as a postoperative pulmonary complication. No malfunction was found in patients who underwent SLR with the stapling device. When compared with the historical group, the SLR group had a significantly lower incidence of air leakage from the staple line (6.3% vs. 28.5%, P < 0.001) and significantly shorter indwelling chest drainage time (P = 0.049) and length of hospital stay (P < 0.001)., Conclusions: The use of SLR in pulmonary resection was safe and effective. When compared with conventional products, SLR could control intraoperative air leakage from the staple line and shorten time needed for indwelling chest drainage and the length of hospital stay., (© 2024.

- Abstract
Purpose: Positive vitreous pressure (PVP) secondary to intraoperative acute hypotony during penetrating keratoplasty can result in extrusion of the intraocular lens and vitreous. Currently described techniques are difficult or impossible to apply intraoperatively when positive vitreous pressure is noticed in an "open sky" situation after excision of the host corneal button., Methods: We describe a technique where pupil scaffolding is used to prevent intraocular lens or crystalline lens extrusion by simply closing the pupil with a temporary suture that holds the retropupillary contents back. Once the eye is thus stabilized, the donor cornea is sutured rapidly after which the pupillary knot is cut and removed using microscissors and microforceps., Results: Five patients undergoing penetrating keratoplasty under peribulbar anesthesia underwent this technique after experiencing PVP after host corneal button excision. PVP was successfully controlled in all 5 patients, and the optical grafts remained clear in the postoperative period., Conclusions: Temporary pupillary scaffolding can help control PVP and prevent ocular content extrusion during PKP surgeries., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
This study examined how different goal-directed fluid therapy types affected low blood pressure and fluid infusion during robot-assisted laparoscopic gynecological surgery. They used carotid corrected flow time (FTc) and tidal volume stimulation pulse pressure variation (VtPPV) to check the patient's volume status and responsiveness. The findings indicated that various fluid therapy targets significantly influence intraoperative hypotension and fluid requirements. However, the study exclusively employed unilateral carotid ultrasound assessments, potentially overlooking physiological or pathological variations in blood flow between the left and right carotid arteries. This methodological choice raises concerns as guidelines recommend bilateral measurements for a more comprehensive evaluation. The lack of bilateral assessments could affect the study's reliability and reproducibility. Justifying the unilateral measurement approach is essential for validating clinical findings. Future research should adopt bilateral carotid ultrasound assessments or provide a detailed rationale for unilateral measurements to enhance the robustness and accuracy of clinical evaluations., (© 2024.

- Abstract
Transanal total mesorectal excision (taTME) has improved the laparoscopic dissection for rectal cancer in the narrow pelvis. Although taTME has more clinical benefits than laparoscopic surgery, such as a better view of the distal rectum and direct determination of distal resection margin, an intraoperative urethral injury could occur in excision ta-TME. This study aimed to determine the feasibility and efficacy of the ta-TME with IRIS U kit surgery. This retrospective study enrolled 10 rectal cancer patients who underwent a taTME with an IRIS U kit. The study endpoints were the safety of access (intra- or postoperative morbidity). The detectability of the IRIS U kit catheter was investigated by using a laparoscope-ICG fluorescence camera system. Their mean age was 71.4±6.4 (58-78) years; 80 were men, and 2 were women. The mean operative time was 534.6 ± 94.5 min. The coloanal anastomosis was performed in 80%, and 20% underwent abdominal peritoneal resection. Two patients encountered postoperative complications graded as Clavien-Dindo grade 2. The transanal approach with IRIS U kit assistance is feasible, safe for patients with lower rectal cancer, and may prevent intraoperative urethral injury., (© 2024. The Author(s).)

- Abstract
Background: As resources into gynecological surgical simulation training increase, research showing an association with improved clinical outcomes is needed., Objective: To evaluate the association between surgical simulation training for total laparoscopic hysterectomy (TLH) and rates of intraoperative vascular/visceral injury (primary outcome) and operative time., Search Strategy: We searched Medline OVID, Embase, Web of Science, Cochrane, and CINAHL databases from the inception of each database to April 5, 2022. Selection Critera: Randomized controlled trials (RCTs) or cohort studies of any size published in English prior to April 4, 2022., Data Collection and Analysis: The summary measures were reported as relative risks (RR) or as mean differences (MD) with 95% confidence intervals using the random effects model of DerSimonian and Laird. A Higgins I2 >0% was used to identify heterogeneity. We assessed risk of bias using the Cochrane Risk of Bias tool 2.0 (for RCTs) and the Newcastle Ottawa Scale (for cohort studies)., Main Results: The primary outcome of this systematic review and meta-analysis was to evaluate the impact of simulation training on the rates of vessel/visceral injury in patients undergoing TLH. Of 989 studies screened 3 (2 cohort studies, 1 randomized controlled trial) met the eligibility criteria for analysis. There was no difference in vessel/visceral injury (OR 1.73, 95% CI 0.53-5.69, p=0.36) and operative time (MD 13.28, 95% CI -6.26 to 32.82, p=0.18) when comparing before and after simulation training., Conclusion: There is limited evidence that simulation improves clinical outcomes for patients undergoing TLH.

- Abstract
Purpose: To compare the short-term changes in cornea, retina, and choroid of femtosecond laser-assisted cataract surgery (FLACS) with conventional phacoemulsification (CPS) in high myopia patients with cataract., Setting: Affiliated Hospital of Nantong University, Jiangsu Province, China., Design: Prospective single-center study., Methods: Demographics, ocular clinical features, ultrasound power, absolute phacoemulsification time, and effective phacoemulsification time were recorded for each patient. Endothelial cell density (ECD), central corneal thickness (CCT), corrected distance visual acuity (CDVA), intraocular pressure (IOP), center foveal thickness (CFT), subfoveal choroidal thickness (SFCT), and choroidal vascularity index (CVI) were evaluated preoperatively and at 1 week, 1 month, and 3 months postoperatively. Intraoperative parameters and intraoperative/postoperative complications were recorded., Results: 97 eyes (46 eyes and 51 eyes in the FLACS and CPS groups, respectively) were included and analyzed. Effective phacoemulsification time was lower in the FLACS group compared with the CPS group ( P < .05). The increase in CCT was significantly lower in the FLACS group compared with the CPS group at 1 week and 1 month ( P < .05). CDVA and IOP were similar in both groups at the final visit ( P > .05). The ECD decreased was lower among CPS patients compared with FLACS patients. CFT, SFCT, and CVI increase in both groups but were increased more in the CPS group with high myopia patients. No serious complications occurred in either group., Conclusions: FLACS is a more safety and effective in cataract patients with high myopia. It has advantages in effectively reducing EPT and promoting faster recovery of the cornea, macular, and choroidal thickness., (Copyright © 2024 Published by Wolters Kluwer on behalf of ASCRS and ESCRS.)

- Abstract
A tracheostomy is usually necessary for long-term mechanical ventilation or complicated weaning. Other indications include swallowing disorders with recurrent aspiration in neuromuscular disease and high-grade subglottic stenosis. The tracheostomy can be performed as a percutaneous dilatational tracheostomy or as a surgical tracheostomy. The complication rate is low, and intraoperative complications are differentiated from early and late postoperative complications. This article aims to present the indications, the techniques and complications of percutaneous dilatational and surgical tracheostomy, and highlights the long-term complications of tracheal stenosis and tracheomalacia., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

- Abstract
Background: There is no consensus regarding safe intraoperative blood pressure thresholds that protect against postoperative acute kidney injury (AKI). This review aims to examine the existing literature to delineate safe intraoperative hypotension (IOH) parameters to prevent postoperative AKI., Methods: PubMed, Cochrane Central, and Web of Science were systematically searched for articles published between 2015 and 2022 relating the effects of IOH on postoperative AKI., Results: Our search yielded 19 articles. IOH risk thresholds ranged from <50 to <75 mmHg for mean arterial pressure (MAP) and from <70 to <100 mmHg for systolic blood pressure (SBP). MAP below 65 mmHg for over 5 min was the most cited threshold (N = 13) consistently associated with increased postoperative AKI. Greater magnitude and duration of MAP and SBP below the thresholds were generally associated with a dose-dependent increase in postoperative AKI incidence., Conclusions: While a consistent definition for IOH remains elusive, the evidence suggests that MAP below 65 mmHg for over 5 min is strongly associated with postoperative AKI, with the risk increasing with the magnitude and duration of IOH., Competing Interests: Declaration of competing interest This work is supported by NIH/NIGMS RO1 GM-110240 (MR, AB), Davis Foundation – University of Florida (MR), NIH/NIGMS P50 GM111152 (AB), and NIH/NIBIB 1R21EB027344-01 (AB).

- Abstract
Perioperative anaphylaxis is a rare and unpredictable event that continues to cause patient harm. More work is needed to decrease the risk to patients through measures to limit sensitisation, optimise management and investigation, and ensure that patients are not inadvertently re-exposed to allergens. Robust epidemiological data such as that provided by the consecutive GERAP surveys over the past 30 yr have been invaluable in defining the problem, identifying emerging allergens, acting as a catalyst for change, and stimulating research., (Copyright © 2024 British Journal of Anaesthesia.

- Abstract
Background: Intraoperative hypotension during cesarean section has become a serious complication for maternal and fetal healthy. It is commonly encountered by subarachnoid anesthesia. However, currently used control methods have varying degrees of side effects, such as drugs. The Root Cause Analysis (RCA) - Plan, Do, Check, Act (PDCA) is a new model of care that identifies the root causes of problems. The study aimed to demonstrate the usefulness of RCA-PDCA nursing methods in preventing intraoperative hypotension during cesarean section and to predict the occurrence of intraoperative hypotension through a machine learning model., Methods: Patients who underwent cesarean section at Traditional Chinese Medicine of Southwest Medical University from January 2023 to December 2023 were retrospectively screened, and the data of their gestational times, age, height, weight, history of allergies, intraoperative vital signs, fetal condition, operative time, fluid out and in, adverse effects, use of vasopressor drugs, anxiety-depression-pain scores, and satisfaction were collected and analyzed. The statistically different features were screened and five machine learning models were used as predictive models to assess the usefulness of the RCA-PDCA model of care., Results: (1) Compared with the general nursing model, the RCA-PDCA nursing model significantly reduces the incidence of intraoperative hypotension and postoperative complications in cesarean delivery, and the patient experience is comfortable and satisfactory. (2) Among the five machine learning models, the RF model has the best predictive performance, and the accuracy of the random forest model in preventing intraoperative hypotension is as high as 90%., Conclusion: Through computer machine learning model analysis, we prove the importance of the RCA-PDCA nursing method in the prevention of intraoperative hypotension during cesarean section, especially the Random Forest model which performed well and promoted the application of artificial intelligence computer learning methods in the field of medical analysis., Competing Interests: Declaration of competing interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024.

- Abstract
Introduction: The use of esophageal temperature monitoring (ETM) for the prevention of esophageal injury during atrial fibrillation (AF) ablation is often advocated. However, evidence supporting its use is scarce and controversial. We therefore aimed to review the evidence assessing the efficacy of ETM for the prevention of esophageal injury., Methods: We performed a meta-analysis and systematic review of the available literature from inception to December 31, 2022. All studies comparing the use of ETM, versus no ETM, during radiofrequency (RF) AF ablation and which reported the incidence of endoscopically detected esophageal lesions (EDELs) were included., Results: Eleven studies with a total of 1112 patients undergoing RF AF ablation were identified. Of those patients, 627 were assigned to ETM (56%). The overall incidence of EDELs was 9.8%. The use of ETM during AF ablation was associated with a non significant increase in the incidence of EDELs (12.3% with ETM, vs. 6.6 % without ETM, odds ratio, 1.44, 95%CI, 0.49, 4.22, p = .51, I
2 = 72%). The use of ETM was associated with a significant increase in the energy delivered specifically on the posterior wall compared to patients without ETM (mean power difference: 5.13 Watts, 95% CI, 1.52, 8.74, p = .005)., Conclusions: The use of ETM does not reduce the incidence of EDELs during RF AF ablation. The higher energy delivered on the posterior wall is likely attributable to a false sense of safety that may explain the lack of benefit of ETM. Further randomized controlled trials are needed to provide conclusive results., (© 2024 The Authors. Pacing and Clinical Electrophysiology published by Wiley Periodicals LLC.)- Published

- Abstract
Background: This study was conducted to compare the effects of heat preservation by two recommended methods, heated infiltration solutions and forced-air heating blankets, in patients undergoing liposuction under general anesthesia., Methods: Forty patients were divided into four groups based on whether heated infiltration solutions or forced-air heating blankets were used. Group A received general anesthesia liposuction plastic surgery routine temperature care. Based on the care measures of group A, heated infiltration solutions were used in group B; forced-air heating blanket was used in group C; and heated infiltration solutions and forced-air heating blankets were both used in group D. The primary end point was intraoperative and perioperative temperature measured with an infrared tympanic membrane thermometer. Secondary end points included surgical outcomes, subjective experience, and adverse events., Results: Compared with group A, the intraoperative body temperatures of groups B, C, and D were significantly higher, indicating that the two intervention methods were helpful on increasing the core body temperature. Pairwise comparisons of these three groups showed that there was no significant difference between group C and group D. However, using forced-air heating blankets had a marked effect compared with using heated infiltration solutions alone at three time points. The same trend could be seen in other surgical outcomes., Conclusions: Heated infiltration solutions and forced-air heating blankets could reduce the incidence of intraoperative hypothermia and improve patients' prognosis after liposuction under general anesthesia. Compared with the heated infiltration fluid, the forced-air heating blanket may have a better thermal insulation effect., Level of Evidence I: This journal requires that authors assign a level of evidence to each article.
