The Effect of Active Warming Before Total Knee Arthroplasty on Intraoperative Body Temperature and Comfort: A Randomized Control Trial.

PURPOSE: This study was conducted to determine the effect of active warming on intraoperative body temperature and comfort before total knee arthroplasty. DESIGN: This study was a randomized controlled trial designed according to the Consolidated Standards of Reporting Trials. METHODS: The study was conducted on 54 patients in a public hospital in Türkiye. In the study, patients in the intervention group were prewarmed for 30 minutes before surgery. The patients in the intervention and control groups were warmed with a warming bed during the surgery. FINDINGS: In this study, the first entry temperature to the operating room after anesthesia induction and the mean body temperature of the patients in the intervention group were higher than the control group. The mean comfort score of the patients in the intervention group was higher than the control group. CONCLUSIONS: As a result of this study, we found that the combination of preoperative prewarming and intraoperative warming reduced the decrease in the patient's body temperature and increased the comfort.

Evaluation of the Opinions of Surgery Patients on Perioperative Privacy.

PURPOSE: To evaluate surgical patients' perceptions of perioperative privacy. DESIGN: A descriptive and cross-sectional study. METHODS: A total of 172 patients who underwent surgical intervention at a state hospital were included. A Patient Information Form and the Perioperative Privacy Scale (PPS) were used to collect data. The data were analyzed using descriptive statistical methods, Mann-Whitney U test, and Kruskal-Wallis H test. FINDINGS: With a mean age of 56.81 ± 1.29 years, 56.4% of the patients were male. Over half of all patients (51.7%) were familiar with the concept of patient privacy, and the vast majority (94.2%) felt that their privacy was protected by the health care staff during their hospital stay. The mean PPS score was 74.38 ± 10.44. A statistically significant difference was found between the patients' marital status, education level, health insurance, attention to privacy by health personnel, and the mean scores of the PPS (P < .05). CONCLUSIONS: The research found that patients who underwent surgery felt that their privacy was well-protected during the perioperative period. To maintain patient privacy during this process, surgical nurses should continue their current practices and emphasize the importance of the subject in in-service training programs.

Anaphylaxis to Protamine During a Carotid Endarterectomy.

Protamine sulfate is commonly used to reverse the anticoagulant effects of unfractionated heparin (UFH) during surgical procedures, but its administration can sometimes trigger severe adverse reactions, including life-threatening anaphylaxis. We present the case of a 77-year-old male undergoing carotid endarterectomy who developed profound hypotension and tachycardia following protamine infusion. Anaphylaxis was confirmed by elevated tryptase levels. This case emphasizes the importance of vigilant monitoring during protamine administration, particularly in high-risk patients, and highlights the need to consider alternative reversal strategies to enhance patient safety.

Association of Perioperative Skeletal Muscle Index Change With Outcome in Colorectal Cancer Patients.

BACKGROUND: The association between perioperative changes in the skeletal muscle index (SMI) and colorectal cancer (CRC) outcomes remains unclear. We aim to explore perioperative change patterns of SMI and evaluate their effects on long-term outcomes in CRC patients. METHODS: This retrospective cohort study included Stage I-III CRC patients who underwent curative resection between 2012 and 2019. SMI at the third lumbar vertebra level was calculated using computed tomography scans. Optimal cut-off values for SMI were defined separately for males and females and classified as high or low preoperatively and at 3, 6, 9 and 12 months postoperatively. SMI status was further categorized into different perioperative SMI change patterns: highpre-highpost, highpre-lowpost, lowpre-highpost and lowpre-lowpost. The association with recurrence-free survival (RFS) and overall survival (OS) was examined using Cox proportional hazards models. RESULTS: A total of 2222 patients (median [interquartile range] age, 60.00 [51.00-68.00] years; 1302 (58.60%) men; 222 (9.99%) with preoperative low SMI) were evaluated. During a median follow-up of 60 months, 375 patients (16.88%) died, and 617 patients (27.77%) experienced a recurrence. Multivariate Cox model analysis showed that, compared to patients with highpre-highpost, those with highpre-lowpost (HR = 3.32, 95% CI: 1.60-6.51; HR = 2.54, 95% CI: 1.03-6.26; HR = 2.93, 95% CI: 1.19-7.19, all p < 0.05) had significantly worse RFS and OS (HR = 4.07, 95% CI: 1.55-10.69; HR = 4.78, 95% CI: 1.40-16.29; HR = 9.69, 95% CI: 2.53-37.05, all p < 0.05), at postoperative 6, 9 and 12 months, respectively. Patients with lowpre-lowpost were an independent prognostic factor for worse OS at postoperative 12 months (HR = 3.20, 95% CI: 1.06-9.71, p = 0.040). Patients with lowpre-highpost had similar risk of RFS compared to those with highpre-highpost at postoperative 3, 6 and 12 months (HR = 1.49, 95% CI: 0.75-2.98; HR = 1.05, 95% CI: 0.45-2.43; HR = 1.36, 95% CI: 0.31-6.06, all p > 0.05) and similar risk of OS at postoperative 3, 6, 9 and 12 months (all p > 0.05). CONCLUSIONS: Patients with a high preoperative SMI that decline postoperatively have poor RFS and OS. Consistently low SMI also correlates with worse OS. Patients with low SMI but increased after resection are not an indicator of better prognosis. Routine measurement of postoperative, rather than preoperative, SMI is warranted. Patients with low SMI are at an increased risk for recurrence and death, especially within the first year after surgery.

Factor Xa Inhibitors and Low Molecular Weight Heparins in Perioperative Surgical Thromboprophylaxis: A Network Meta-Analysis.

BACKGROUND: venous thromboembolism (VTE) prophylaxis is crucial for reducing the risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). This network metaanalysis was carried out to determine the most effective intervention among selective Xa inhibitors and low molecular weight heparins (LMWHs) for perioperative surgical thromboprophylaxis in major abdominal, pelvic, lumbar spine, and lower limb surgeries. METHODS: A systematic literature search was conducted for randomized controlled trials (RCTs) comparing selective factor Xa inhibitors, LMWHs, and placebo as thromboprophylaxis agents in major abdominal, pelvic, lumbar spine, and lower limb surgeries. A Bayesian network metaanalysis was performed to compare all interventions for the risk of developing DVT, VTE, major VTE, total bleeding, and major bleeding. The surface under the cumulative ranking curves was used to rank all interventions. RESULTS: Of 1788 retrieved references, 42 RCTs comparing 11 anticoagulants were included. As compared to enoxaparin, the risk of DVT was significantly reduced in patients treated with fondaparinux [RR: 0.53 (95% CrI: 0.31, 0.93)] and rivaroxaban [RR: 0.42 (95% CrI: 0.27, 0.64)]; VTE in patients treated with bemiparin [RR: 0.09 (95% CrI: 0, 0.7)], edoxaban [RR: 0.43 (95% CrI: 0.18, 0.96)], fondaparinux [RR: 0.55 (95% CrI: 0.34, 0.91)] and rivaroxaban [RR: 0.56 (95% CrI: 0.34, 0.85)]; major VTE in patients treated with rivaroxaban [RR: 0.26 (95% CrI: 0.11, 0.6)]. According to the surface under the cumulative ranking curves (SUCRA) value, fondaparinux and bemiparin increase the risk of serious bleeding more than other factor Xa inhibitors and LMWHs. CONCLUSION: Rivaroxaban, fondaparinux, edoxaban, and bemiparin are superior perioperative thromboprophylaxis agents than enoxaparin in major surgeries. Fondaparinux and bemiparin have shown the highest risk of major bleeding compared to other factor Xa inhibitors and LMWHs.

Gut Microbiota and Probiotics in Perioperative Management: A Narrative Review.

The human gut is the abode of several complex and diverse microbes. It is a fact that the human brain is interconnected with the spinal cord and sense organs; however, there is also a possibility of a connection between the brain and the gut microbiome. The human gut can be altered in various ways, the principal method being the intake of prebiotics, probiotics and synbiotics. Can this alteration in the gut microbiome be clinically utilised in the perioperative period? We conducted a literature search related to this topic using databases and search engines (Medical Literature Analysis and Retrieval System Online {MEDLINE}, Embase, Scopus, PubMed and Google Scholar). The search revealed some preclinical and clinical studies in animals and humans that demonstrate the alteration of the gut microbiome with the use of anxiolysis, probiotics/prebiotics and other perioperative factors including opioids, anaesthetics and perioperative stress. The significant effects of this alteration have been seen on preoperative anxiety and postoperative delirium/cognitive dysfunction/pain. These effects are described in this narrative review, which opens up newer vistas for high-quality research related to the gut microbiome, gut-brain axis, the related signaling pathways and their clinical application in the perioperative period.

Perioperative Outcomes of Total Hip Arthroplasty in Trisomy 21 Patients in Comparison With a Control Population: Analysis From a Large National Sample of 367,894 Patients.

BACKGROUND: Literature on the outcomes of total hip arthroplasty (THA) has established the procedure as a gold standard for hip arthritis. However, postoperative outcomes after THA in specific conditions such as Down's syndrome (DS) have been sparsely described. This large database analysis of over 367,000 patients was aimed at evaluating the immediate postoperative results including morbidity and mortality rates after THA among DS patients and comparing these with a control population. METHODS: Data from the National Inpatient Sample (NIS) database Healthcare Cost and Utilization Project (HCUP) was reviewed retrospectively from 2016 to 2019 on THAs. Among 367,894 patients, 129 were identified with a diagnosis of DS. Complex primaries and revisions were excluded. Demographics, admission details, and perioperative variables including morbidity and mortality rates were compared between DS patients and controls. RESULTS: Patients with DS were younger than the control population (43.3 versus 65.9 years, p=0.002), had a greater preponderance of men, had a lower incidence of smoking and diabetes, and had a relatively higher incidence of non-elective THA. The former also had a longer mean length of stay (LoS) and higher mean costs to healthcare. Two patients with DS died after a THA, making the mortality rate 17-fold higher in DS patients. Higher rates of postoperative anemia (31.8% versus 19.6%, p<0.001), pneumonia (2.3% versus 0.3%), and pulmonary embolism (p=0.0.12) were seen in the DS group. Also seen in the DS group were higher risks of periprosthetic fractures (p=0.020) and periprosthetic joint infections (PJIs) (p=0.047). CONCLUSIONS: Results from a total hip arthroplasty continue to positively transform the lives of patients with end-stage hip arthritis from varying etiologies. In the special cohort of Down's syndrome, a thorough discussion is essential with reference to the relatively higher morbidity and mortality in this group of patients. Documented conversations between patients and their families and healthcare providers should consist of detailed deliberations on the pros and cons of surgery and its potential impacts.

Multidisciplinary Management of a Pregnant Trauma Patient With Gestational Diabetes: A Case Report on Combined Regional Anesthesia.

This clinical case report describes the management of a 36-year-old pregnant female at 36 weeks gestation, who was admitted to King Abdulaziz Medical City following a motor vehicle accident. The patient, with a history of gestational diabetes mellitus, sustained multiple fractures requiring surgical intervention. A combined spinal and supraclavicular block was chosen for anesthesia, with a contingency plan for general anesthesia and emergency cesarean section if needed. The surgical procedures were completed successfully, and the patient was stable postoperatively.

Enhanced recovery after adolescent idiopathic scoliosis surgery care pathway: Perioperative strategy to improve outcome.

Intro: AIS surgery generates a high inflammatory stress response which might influence the outcome in the perioperative period. Enhanced Recovery After Surgery (ERAS) is a global multidisciplinary care pathway aimed to improve patient's recovery. Research question: The purpose of this article is to expose our actual ERAS protocol for AIS surgery and compare it with the earlier non ERAS management in our institution.Our primary outcome focus on the re-hospitalisation and complications rates at 30 and 90 days postoperatively. Our secondary outcomes focus on the overall morphine consumption, pain scores and side effects during the hospitalisation. Material: We compare the results of the ERAS group (2019-2022) with the previous existing classical care pathway (2017-2019). The data were collected in our standard medical files. Results: Our ERAS care pathway for AIS surgery lead to consequently improve the outcome regarding the VAS scores, the morphine consumption, the LOS and the complication and re hospitalisation rates. Discussion: Regarding our results, ERAS care pathway for AIS surgery appears to be efficient in terms of benefits on complications rates, LOS and opioid consumption.Intrathecal morphine and "anti-inflammatory" anaesthesia provides a good quality of pain management and allows the patient to get up early.A superiority trial might be interesting to highlight the role of the ERAS pathway in AIS surgery.

Amino Acid Infusion for Perioperative Functional Renal Protection: A Meta-analysis.

OBJECTIVES: Acute kidney injury (AKI) is a common perioperative complication. To date, no single intervention has been proven effective for AKI prevention in this setting. However, intravenous amino acids (AA) administration may recruit renal functional reserve and, thereby, attenuate the perioperative loss of the glomerular filtration rate. DESIGN: We performed a meta-analysis to assess the efficacy of AA infusion for perioperative renal functional protection. SETTING AND PARTICIPANTS: We performed a meta-analysis of controlled studies in perioperative patients evaluating intravenous AA infusion versus any comparator. MEASUREMENTS: The primary outcome was AKI at longest follow-up. We performed a random effects meta-analysis on the relative risk (RR) scale to assess the effect of AA infusion. We used a Bayesian approach to estimate the probability of benefit (RR < 1) for the primary outcome. Secondary outcomes included renal replacement therapy, serum creatinine, and estimated glomerular filtration rate. Tertiary outcomes included mechanical ventilation duration, intensive care unit and hospital length of stay and mortality (PROSPERO: CRD42024547225). RESULTS: We identified 15 studies (14 randomized controlled trials and 1 prospective before-after study) reporting at least one outcome of interest (4,544 patients), with 6 studies (4,084 patients) reporting the primary outcome. AKI occurred 504 of 2,041 (24.7%) in AA patients versus 614 of 2,041 (30.1%) in controls (RR, 0.66; 95% confidence interval, 0.47-0.94; I2 = 50%; p = 0.02), which corresponded with a 99.1% probability of AKI reduction with AA. Moreover, consistent with these findings, AA decreased serum creatinine and hospital length of stay and increased the estimated glomerular filtration rate. CONCLUSIONS: This meta-analysis suggests that AA administration likely decreased the perioperative incidence of AKI.

Consensus-Building Processes for Implementing Perioperative Care Pathways in Common Elective Surgeries: A Systematic Review.

AIMS: To identify and understand the different approaches to local consensus discussions that have been used to implement perioperative pathways for common elective surgeries. DESIGN: Systematic review. DATA SOURCES: Five databases (MEDLINE, CINAHL, EMBASE, Web of Science and the Cochrane Library) were searched electronically for literature published between 1 January 2000 and 6 April 2023. METHODS: Two reviewers independently screened studies for inclusion and assessed quality. Data were extracted using a structured extraction tool. A narrative synthesis was undertaken to identify and categorise the core elements of local consensus discussions reported. Data were synthesised into process models for undertaking local consensus discussions. RESULTS: The initial search returned 1159 articles after duplicates were removed. Following title and abstract screening, 135 articles underwent full-text review. A total of 63 articles met the inclusion criteria. Reporting of local consensus discussions varied substantially across the included studies. Four elements were consistently reported, which together define a structured process for undertaking local consensus discussions. CONCLUSIONS: Local consensus discussions are a common implementation strategy used to reduce unwarranted clinical variation in surgical care. Several models for undertaking local consensus discussions and their implementation are presented. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Advancing our understanding of consensus building processes in perioperative pathway development could be significantly improved by refining reporting standards to include criteria for achieving consensus and assessing implementation fidelity, alongside advocating for a systematic approach to employing consensus discussions in hospitals. IMPACT: These findings contribute to recognised gaps in the literature, including how decisions are commonly made in the design and implementation of perioperative pathways, furthering our understanding of the meaning of consensus processes that can be used by clinicians undertaking improvement initiatives. REPORTING METHOD: This review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. No patient or public contribution. TRIAL REGISTRATION: CRD42023413817.

Effect of perioperative erythropoietin on postoperative morbidity and mortality after cardiac surgery: A meta-analysis of randomized controlled trials.

OBJECTIVE: Cardiac surgery is known to have high rates of perioperative red blood cell (RBC) transfusions which are associated with increased postoperative mortality and morbidity. Perioperative erythropoietin (EPO) has been suggested to lower perioperative RBC transfusions, and the effect on postoperative morbidity or mortality is unknown. METHODS: The registered study protocol is available on PROSPERO (CRD42022314538). We searched the Pubmed, EMbase, and Cochrane CENTRAL databases for randomized controlled trials (RCT) of EPO in cardiac surgery. Outcomes were short-term mortality, acute kidney injury (AKI), re-operation, cerebrovascular accident (CVA), perioperative myocardial infarction (MI), infectious complications, and RBC transfusions. RCT studies of perioperative EPO that reported at least one prespecified outcome of interest were included. RESULTS: A total of 21 RCT's (n = 2,763 patients) were included. Mortality analysis included 17 studies (EPO 1,272 patients, control 1,235) and showed no significant difference (risk difference (RD) 0.0004, 95%CI: -0.016, 0.009). EPO did not reduce the incidence of AKI (RD -0.006, 95% CI: -0.038, 0.026) and reoperation (RD 0.001, 95% CI: -0.013, 0.015). The incidence of CVA (RD -0.004, 95% CI: -0.015, 0.007) and perioperative MI (RD -0.008, 95% CI: -0.021, 0.005) was similar between the groups. CONCLUSIONS: Although EPO had been proven to reduce perioperative RBC transfusions, we did not find that it reduces the incidence of postoperative short-term mortality, AKI, and reoperation. The study results support that perioperative EPO is also safe, with no rise in thrombotic events, including CVA and perioperative MI.

Pre-operative care intensity and cost for renal colic: implications for surgical value-based reforms.

OBJECTIVES: To identify pre-operative patient/facility factors associated with post-operative and total episode-related costs using renal colic as a model surgical condition to improve value-based payment models. METHODS: Using state Healthcare Cost and Utilization Project data, we performed a retrospective cohort study examining peri-operative costs for individuals presenting to an emergency department for renal colic and who ultimately underwent definitive surgical management. We estimated multivariable ordered and binary logistic regressions to examine the association between pre-operative and operative cost quartiles on the probability of specific post-operative cost quartiles after accounting for hospital and individual factors. We also performed logistic regressions to identify patients who deviated from predicted perioperative cost pathways. RESULTS: Among 2,736 individuals included in our analysis, episode-related costs ranged from $4,536 (bottom quartile) to $26,662 (top quartile). Individuals in the highest pre-operative cost quartile experienced an 11.7%-point higher probability of remaining in the highest post-operative cost quartile relative to those in the lowest pre-operative cost quartile (95% CI 0.0709, 0.163; p<0.001). Delays in surgery (95% CI 0.0869, 0.163; P<0.001) and Medicaid vs. private insurance (95% CI 0.01, 0.0728; P<0.01) were associated with a 12.5% and 4.1%-point higher probability of being in the top quartile of pre-operative costs, respectively. Treating facility experience with value-based payment models did not influence peri-operative costs. CONCLUSIONS: Using renal colic as a model surgical condition, our novel findings suggest that pre-operative costs are associated with both post-operative and total episode-related costs, and should be accounted for when designing future value-based payment models.

Assessing the Efficacy of Thoracic Erector Spinae Plane Block for Postoperative Analgesia in Lumbosacral Spine Surgery: A Prospective Quasi-experimental Study.

Background and aims Optimal postoperative care and analgesia are the key factors in the management of cases of lumbosacral spine surgery. The erector spinae plane (ESP) block is a recently evolving entity and has a dynamic role in postoperative pain management. However, its role in the management of pain in lumber spinal surgeries is still not clear, and the literature remains anecdotal. Therefore, we planned to study the efficacy of ultrasound-guided preoperative ESP block at the T12 level using levobupivacaine for perioperative analgesia in lumbosacral spine surgeries. Methods A total of 60 patients scheduled for elective or emergency lumbosacral spine surgery were divided into two groups - the GA group received standard general anesthesia (GA) and the GA+ESP group received standard general anesthesia along with ultra-sound guided ESP block at the T12 level with a bilateral injection of 20 ml 0.25% levobupivacaine. Perioperative analgesia was assessed by total intra-operative fentanyl dose and frequency, intra-operative hemodynamic parameters, post-operative numeric rating scale (NRS) scores, time of first systemic rescue analgesia, tramadol usage, mobilization day, and hospital stay duration.  Results Intraoperative fentanyl sparing was observed in 83% of the GA+ESP group compared to 33% in the GA group. Postoperative tramadol sparing was observed in 80% of the GA+ESP group compared to 26.7% of the GA group. Twenty-four-hour postoperative NRS scores >3/10 were observed in 20% of the GA+ ESP group compared to 73.3% of the GA group. Conclusion In this study, superior perioperative analgesia, opioid-sparing effect, and decreased requirement of postoperative rescue analgesia were observed with ESP block.

The effect of transcutaneous electrical acupoint stimulation on postoperative awakening after general anaesthesia: a systematic review and meta-analysis.

Background: The existing body of research concerning the impact of transcutaneous electrical acupoint stimulation (TEAS) on early postoperative recovery is marked by a lack of consensus. This meta-analysis, encompassing a systematic review of randomised controlled trials, seeks to critically assess the efficacy of TEAS in relation to awakening from general anaesthesia in the postoperative period. Methods: The inclusion criteria for this study were peer-reviewed randomised controlled trials that evaluated the influence of TEAS on the process of regaining consciousness following general anaesthesia. A comprehensive search was conducted across several reputable databases, including PubMed, Embase, the Cochrane Library, the China National Knowledge Infrastructure, the VIP Database, the SinoMed Database, and the WANFANG Medical Database. The search was not limited by date, extending from the inception of each database up to December 2023. The methodological quality and risk of bias within the included studies were appraised in accordance with the guidelines outlined in the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1, and its associated tool for assessing risk of bias. Results: The analysis encompassed 29 studies involving a total of 2,125 patients. Participants in the TEAS group demonstrated a significantly shorter duration to achieve eye-opening [mean difference (MD), -3.16 min; 95% confidence interval (CI), -3.93 to -2.39], endotracheal extubation (MD, -4.28 min; 95% CI, -4.79 to -3.76), and discharge from the post-anaesthesia care unit (MD, -8.04 min; 95% CI, -9.48 to -6.61) when compared to the control group receiving no or sham stimulation. Additionally, the TEAS group exhibited markedly reduced mean arterial blood pressure (MD, -9.00 mmHg; 95% CI, -10.69 to -7.32), heart rate (MD, -7.62 beats/min; 95% CI, -9.02 to -6.22), and plasma concentrations of epinephrine (standardised MD, -0.81; 95% CI, -1.04 to -0.58), norepinephrine (MD, -47.67 pg/ml; 95% CI, -62.88 to -32.46), and cortisol (MD, -110.92 nmol/L; 95% CI, -131.28 to -90.56) at the time of extubation. Furthermore, the incidence of adverse effects, including agitation and coughing, was considerably lower in the TEAS group relative to the control group (odds ratio, 0.30; 95% CI, 0.22-0.40). Conclusion: The findings of this study indicate that TEAS may hold promise in facilitating the return of consciousness, reducing the interval to awakening post-general anaesthesia, and enhancing the awakening process to be more tranquil and secure with a diminished likelihood of adverse events. However, caution must be exercised in interpreting these results due to the notable publication and geographical biases present among the studies under review. There is an imperative for further high-quality, low-bias research to substantiate these observations. Systematic review registration: The review protocol was registered with the PROSPERO International Prospective Register of Systematic Reviews (CRD42022382017).

Patient sex and use of tranexamic acid in liver transplantation.

Background: Differences in medical treatment between women and men are common and involve out-of-hospital emergency care, the intensity of pain treatment, and the use of antifibrinolytic treatment in emergency trauma patients. If woman and man receive different antifibrinolytic treatment in highly-standardized major transplant surgery is unknown. Methods: We conducted a retrospective cohort study on patients who underwent liver transplantation at Heidelberg University Hospital, Heidelberg, Germany between 2004 and 2017. Logistic regression analyses were performed to determine if sex is associated with the administration of TXA during liver transplantation. Secondary endpoints included venous thrombotic complications, graft failure, mortality, myocardial infarction, hepatic artery thrombosis, and stroke within the first 30 days after liver transplant as well as length of hospital stay and length of intensive care unit stay. Results: Out of 779 patients who underwent liver transplantation, 262 patients received TXA. Female sex was not associated with intraoperative administration of TXA [adjusted OR: 0.929 (95% CI 0.654; 1.320), p = 0.681]. The secondary endpoints graft failure (13.2% vs. 8.4%, women vs. men, p = 0.039), pulmonary embolism (3.4% vs. 0.9%, women vs. men, p = 0.012), stroke (1.7% vs. 0.4%, women vs. men, p = 0.049), and deep vein thrombosis (0.8% vs. 0%, women vs. men, p = 0.031) within 30 days after liver transplantation were more frequent in women. Mortality, myocardial infarction, and other secondary endpoints did not differ between groups. However, in women, the use of TXA was associated with a lower rate in thromboembolic complications. Conclusion: Our data indicate that different from other scenarios with massive bleeding complications the administration of TXA during liver transplantation is not associated with sex. However, sex is associated with the risk for complications, and in woman TXA might have a preventive effect on the rate of thromboembolic complications. Reasons underlying the observed sex bias rate remain uncertain.

Anesthesia Strategies for the Perioperative Management of Severe Pulmonary Hypertension in Emergency Orthopedic Surgery: A Case Report.

This case report details the perioperative challenges and anesthesia strategies in managing severe pulmonary hypertension (PH) during emergency orthopedic surgery. An 86-year-old male with multiple comorbidities, including severe PH, presented with a hip fracture. Multidisciplinary collaboration was crucial for preoperative optimization, including transfusions, antithrombotic discontinuation, and thromboprophylaxis initiation. Anesthesia management included the use of spinal anesthesia combined with a precautionary epidural catheter insertion, low-dose hyperbaric bupivacaine, and continuous monitoring to prevent hemodynamic instability. Postoperatively, the patient was closely monitored in the surgical intensive care unit. This case highlights the necessity of meticulous planning and proactive monitoring in optimizing outcomes for severe PH in emergency orthopedic surgery.
