Identifying postoperative cognitive dysfunction after elective coronary artery bypass graft surgery in a tertiary centre in Malaysia.

Postoperative cognitive dysfunction (POCD) is a significant concern, with incidences reported up to 70% following cardiac surgery. Therefore, we aim to evaluate the incidence of POCD after elective coronary artery bypass graft (CABG) surgery at our single centre over a one-year period from August 2021 to July 2022. We included 34 patients in the study and conducted serial cognitive assessments up to three months post-surgery. Interestingly, our findings indicated an absence of POCD among patients who underwent elective CABG. Reasons contributing to this outcome are multifactorial, which may include the patients' younger age, higher educational levels, lack of pre-existing neurological disorders, meticulous intraoperative cerebral saturation monitoring, and the duration of aortic crossclamp and cardiopulmonary bypass time.

Current Management of Diverticulitis.

Over the last few decades, our understanding of the pathophysiology and natural history of sigmoid diverticulitis has greatly improved. This knowledge has challenged many of the traditional principles in the management for diverticulitis, such as routine antibiotic administration in all cases, number-based recommendations for elective surgery, and the necessity for an end colostomy in emergency surgery. This review will cover the breadth of management for sigmoid diverticulitis, covering both uncomplicated and complicated disease as well as elective and emergent disease presentations. New and emerging concepts in management will be highlighted with a particular focus on level-1 data, when available.

Enhancing patient informed consent in elective skin cancer surgeries: a comparative study of traditional and digital approaches in a German public hospital.

BACKGROUND: This study aims to investigate the integration of modern sources of patient information, such as videos, internet-based resources, and scientific abstracts, into the traditional patient informed consent process in outpatient elective surgeries. The goal is to optimize the informed consent experience, enhance patient satisfaction, and promote shared decision making (SDM) between patients and surgeons. By exploring different patient informed consent formats and their impact on patient satisfaction, this research seeks to improve healthcare practices and ultimately enhance patient outcomes. The findings of this study will contribute to the ongoing efforts to improve the informed consent process in public hospitals and advance patient-centred care. METHODS: Data collection occurred at the day care clinic of a prominent German public hospital, forming an integral component of a prospective clinical investigation. The study exclusively focused on individuals who had undergone surgical intervention for skin cancer. For the purpose of meticulous data examination, the statistical software SPSS version 21 was harnessed. In the course of this study, a chi-square test was aptly employed. Its purpose was to scrutinize the nuances in patient experiences pertaining to informed consent across four distinct categories, viz., oral informed consent discussion (Oral ICD), written informed consent discussion (Written ICD), video-assisted informed consent discussion (video-assisted ICD), and digitally assisted informed consent discussion (digital-assisted ICD). The primary dataset of this inquiry was diligently gathered via a structured questionnaire administered to a targeted cohort of 160 patients. Within this sample, a balanced representation of genders was observed, encompassing 82 males and 78 females. Their collective age span ranged from 18 to 92 years, with an average age of 71 years. A randomized selection methodology was employed to include participants in this study during the period spanning from July 2017 to August 2018. RESULTS: Significant differences were observed across the groups for all research questions, highlighting variations in patient responses. Video-assisted and digital-assisted IC were rated as superior in patient satisfaction with information compared to written and oral IC. Demographic profiles of the four study groups were found to be comparable. CONCLUSION: The findings of this study indicate that the incorporation of digital technologies in the informed consent process can enhance patient understanding during outpatient elective skin cancer surgeries. These results have important implications for increasing patient satisfaction and improving the SDM process within the hospital environment.

[Glucose metabolism disorders and hypoglycemic therapy in patients hospitalized for elective lower limb arthroplasty: a prospective, single-center, real-world study].

AIM: To assess the incidence of glucose metabolism disorders, administered hypoglycemic therapy and its effectiveness in a cohort of patients with previously diagnosed diabetes mellitus (DM) hospitalized for scheduled lower limb joint arthroplasty. MATERIALS AND METHODS: The study included 502 patients. Medical history, information about previously diagnosed DM and prescribed hypoglycemic therapy were collected in all patients according to medical documentation, as well as according to the patients' survey. Within the preoperative examination, the glucose level was measured, and in patients with previously diagnosed diabetes, measuremaent of the HbA1c level was recommended. RESULTS: The study population included 180 (35.9%) males and 322 females (64.1%). Among them, 99 (19.7%) patients had disorders of glucose metabolism [type 1 diabetes - 1 (0.2%) patient, type 2 diabetes - 90 (17.9%) patients, impaired glucose tolerance (IGT) - 8 (1.6%) patients]. In 8 patients, type 2 diabetes was newly diagnosed during the preoperative examination. HbA1c was measured before hospitalization in 26 patients with diabetes, the mean level was 7.0±1.4%. Regarding the analysis of hypoglycemic therapy, almost half of the patients with DM - 47 (47.5%) - received metformin monotherapy, 8 patients with IGT and 8 patients with newly diagnosed DM did not receive any drug therapy. Target glycemic levels during therapy were achieved in 36 (36.4%) patients, and target HbA1c levels were achieved in 21 patients. CONCLUSION: The cohort of patients hospitalized for elective lower limb joint arthroplasty is characterized by a relatively high incidence of glucose metabolism disorders, and in some patients, DM was newly diagnosed during the preoperative examination. Metformin is most often used as hypoglycemic therapy, and the target values of glycemia during treatment were achieved in less than half of the patients. The monitoring of the level of glycated hemoglobin is low and requires additional population analysis in order to determine the causes and optimize the strategy of patient management.

The Use of Narco SS Score in Predicting Adverse Events in Children Undergoing Major Elective Abdominal Surgery at The University Teaching Hospital, Lusaka, Zambia.

BACKGROUND: The neurological, airway, respiratory, cardiovascular and other, with a subscore of surgical severity (NARCO-SS) is a scoring system which assesses the presence of systemic disease and the risk the operation poses to the patient. A number of patients that undergo major abdominal surgery suffer adverse events. The aim of the study was to determine the reliability of NARCO-SS in predicting peri-operative adverse events and to determine the risk factors for peri-operative adverse events in paediatric patients undergoing elective abdominal surgery. MATERIALS AND METHODS: Prospective cohort study. Consecutively sampled patients from December 2019 to December 2020 were used. Patients scheduled for elective abdominal surgery were scored pre-operatively and end points were; when an adverse event occurred or up to day 30. Analysis of the reliability of the tool, bivariate and multivariate logistics regression was done. RESULTS: One hundred and nineteen patients were enrolled and 49% of them had adverse events. Both bivariate and multivariate analyses showed no significant association between the NARCO-SS score and the occurrence of adverse events. The area under the receiver operating characteristics curve (area under the curve) of the NARCO-SS for adverse events was 0.518; there was a significant correlation between high scores and mortality. Longer duration of surgery and complex surgery were the risk factors for adverse events. CONCLUSIONS: The NARCO-SS score was found to be a poor predictor of adverse events with a fair inter-rater reliability as a scoring tool. Future research could evaluate a modification of neurological and airway categories.

Association of Postoperative Hypoglycemia With Mortality After Elective Craniotomy.

BACKGROUND AND OBJECTIVES: Hypoglycemia is a known risk of intensive postoperative glucose control in neurosurgical patients. However, the impact of postoperative hypoglycemia after craniotomy remains unexplored. This study aimed to determine the association between postoperative hypoglycemia and mortality in patients undergoing elective craniotomy. METHODS: This study involved adult patients who underwent elective craniotomy at the West China Hospital, Sichuan University, between January 2011 and March 2021. We defined moderate hypoglycemia as blood glucose levels below 3.9 mmol/L (70 mg/dL) and severe hypoglycemia as blood glucose levels below 2.2 mmol/L (40 mg/dL). The primary outcome was postoperative 90-day mortality. RESULTS: This study involved 15 040 patients undergoing an elective craniotomy. Overall, 504 (3.4%) patients experienced moderate hypoglycemia, whereas 125 (0.8%) patients experienced severe hypoglycemia. Multivariable analysis revealed that both moderate hypoglycemia (adjusted odds ratio [aOR] 1.86, 95% CI 1.24-2.78) and severe (aOR 2.94, 95% CI 1.46-5.92) hypoglycemia were associated with increased 90-day mortality compared with patients without hypoglycemia. Moreover, patients with moderate (aOR 2.78, 95% CI 2.28-3.39) or severe (aOR 16.70, 95% CI 10.63-26.23) hypoglycemia demonstrated a significantly higher OR for major morbidity after adjustment, compared with those without hypoglycemia. Patients experiencing moderate (aOR 3.20, 95% CI 2.65-3.88) or severe (aOR 14.03, 95% CI 8.78-22.43) hypoglycemia had significantly longer hospital stays than those without hypoglycemia. The risk of mortality and morbidity showed a tendency to increase with the number of hypoglycemia episodes in patients undergoing elective craniotomy (P for trend = .01, <.001). CONCLUSION: Among patients undergoing an elective craniotomy, moderate hypoglycemia and severe hypoglycemia are associated with increased mortality, major morbidity, and prolonged hospital stays. In addition, the risk of mortality and major morbidity increases with the number of hypoglycemia episodes.

Optimal approach to ultrasound-guided quadratus lumborum blocks for postoperative analgesia in elective caesarean section: protocol for systematic review and meta-analysis.

INTRODUCTION: Ultrasound-guided quadratus lumborum blocks are commonly used for postoperative analgesia during caesarean section. Ultrasound-guided quadratus lumborum blocks can be performed through four approaches, including lateral, posterior, anterior, and intramuscular quadratus lumborum blocks. This systematic review and meta-analysis aims to determine the optimal approach to ultrasound-guided quadratus lumborum blocks for postoperative analgesia in elective caesarean section. METHODS AND ANALYSIS: The PubMed, EMBASE, Cochrane Library and Web of Science databases will be systematically searched from their inception to 30 July 2024. Randomised controlled trials that compared the analgesic effects of different ultrasound-guided quadratus lumborum block approaches in elective caesarean section will be included. Only publications in English will be eligible for inclusion. The total postoperative analgesic consumption over 24 hours will be the primary outcome. The time to first analgesic request, postoperative pain scores at rest and during movement, and incidence of adverse effects will be secondary outcomes. RevMan V.5.4 will be used for the statistical analysis. Network meta-analysis will be used for indirect comparisons between different approaches across studies. The Grading of Recommendations Assessment, Development and Evaluation approach will be used to assess the quality of evidence for each outcome. ETHICS AND DISSEMINATION: Ethical approval was not required. The results of this study will be submitted to peer-reviewed journals. PROSPERO REGISTRATION NUMBER: CRD42024503694.

The optimal concentration of ropivacaine for transversus abdominis plane blocks in elective cesarean section: A protocol for systematic review and meta-analysis.

INTRODUCTION: Transversus abdominis plane (TAP) blocks are commonly performed for postoperative analgesia in elective cesarean section. Ropivacaine is the most commonly used local anesthetic for TAP blocks. Currently, the concentration of ropivacaine for TAP blocks is various, and increasing number of randomized controlled trials (RCTs) have compared the effects of different concentration of ropivacaine for TAP blocks in cesarean section. This protocol of a systematic review and meta-analysis aims to identify the optimal concentration of ropivacaine for TAP blocks in elective cesarean section. METHODS AND ANALYSIS: Databases including PubMed, Web of science, the Cochrane library, and EMBASE will be searched from their inception to May 1, 2024. RCTs that investigated the analgesia of different concentrations of ropivacaine for TAP blocks in elective cesarean section will be identified. The analgesia duration will be the primary outcome. Secondary outcomes will include the analgesics consumption over postoperative 24 hours, postoperative pain scores at rest and movement, and the incidence of adverse effects. RevMan 5.4 software will used for statistical analysis. The evidence quality of synthesized results will be evaluated by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. ETHICS AND DISSEMINATION: Ethical approval is not applicable. The results of this study will be published on completion. TRIAL REGISTRATION: PROSPERO registration number: CRD42024496907.

Surgeon- and hospital-level variation in wait times for scheduled non-urgent surgery in Ontario, Canada: A cross-sectional population-based study.

BACKGROUND: Canadian health systems fare poorly in providing timely access to elective surgical care, which is crucial for quality, trust, and satisfaction. METHODS: We conducted a cross-sectional analysis of surgical wait times for adults receiving non-urgent cataract surgery, knee arthroplasty, hip arthroplasty, gallbladder surgery, and non-cancer uterine surgery in Ontario, Canada, between 2013 and 2019. We obtained data from the Wait Times Information System (WTIS) database. Inter- and intra-hospital and surgeon variations in wait time were described graphically with caterpillar plots. We used non-nested 3-level hierarchical random effects models to estimate variation partition coefficients, quantifying the proportion of wait time variance attributable to surgeons and hospitals. RESULTS: A total of 942,605 procedures at 107 healthcare facilities, conducted by 1,834 surgeons, were included in the analysis. We observed significant intra- and inter-provider variations in wait times across all five surgical procedures. Inter-facility median wait time varied between six-fold for gallbladder surgery and 15-fold for knee arthroplasty. Inter-surgeon variation was more pronounced, ranging from a 17-fold median wait time difference for cataract surgery to a 216-fold difference for non-cancer uterine surgery. The proportion of variation in wait times attributable to facilities ranged from 6.2% for gallbladder surgery to 23.0% for cataract surgery. In comparison, surgeon-related variation ranged from 16.0% for non-cancer uterine surgery to 28.0% for cataract surgery. IMPLICATIONS: There is extreme variability in surgical wait times for five common, high-volume, non-urgent surgical procedures. Strategies to address surgical wait times must address the variation between service providers through better coordination of supply and demand. Approaches such as single-entry models could improve surgical system performance.

Early extubation after elective surgical aortic valve replacement during the COVID-19 pandemic.

BACKGROUND: Surgical aortic valve replacement (SAVR) is an established therapy for severe calcific aortic stenosis. Enhanced recovery after cardiac surgery (ERACS) protocols have been shown to improve outcomes for elective cardiac procedures. The COVID-19 pandemic prompted early extubation post-elective surgeries to preserve critical care resources. AIM OF THIS STUDY: To investigate the effects of extubating patients within 6 h post-elective SAVR on hospital and ICU length of stay, mortality rates, ICU readmissions, and postoperative pneumonia. STUDY DESIGN AND METHODS: The retrospective analysis at the University Hospital Aachen, Germany, includes data from 2017 to 2022 and compares a total of 73 elective SAVR patients. Among these, 23 patients were extubated within 6 h (EXT group), while 50 patients remained intubated for over 6 h (INT group). RESULTS: The INT group experienced longer postoperative ventilation, needed more vasopressor support, had a higher incidence of postoperative pneumonia, and longer ICU length of stay. No significant differences were noted in overall hospital length of stay, mortality, or ICU readmission rates between the groups. CONCLUSION: This study demonstrates that early extubation in high-risk, multimorbid surgical aortic valve replacement patients is safe, and is associated with a reduction of pneumonia rates, and with shorter ICU and hospital length of stays, reinforcing the benefits of ERACS protocols, especially critical during the COVID-19 pandemic to optimize intensive care use.

Risk of prolonged postoperative opioid use after elective shoulder replacement: a nationwide cohort study of 5,660 patients from the Danish Shoulder Arthroplasty Registry.

BACKGROUND AND PURPOSE: Several studies from the United States report an increased risk of prolonged opioid use after shoulder replacement. We aimed to determine the incidence and risk factors of prolonged opioid use after elective shoulder replacement in a nationwide Danish population. METHODS: All primary elective shoulder arthroplasties reported to the Danish Shoulder Arthroplasty Registry (DSR) from 2004 to 2020 were screened for eligibility. Data on potential risk factors was retrieved from the DSR and the National Danish Patient Registry while data on medication was retrieved from the Danish National Health Service Prescription Database. Prolonged opioid use was defined as 1 or more dispensed prescriptions on and 90 days after date of surgery (Q1) and subsequently 1 or more dispensed prescriptions 91-180 days after surgery (Q2). Preoperative opioid use was defined as 1 or more dispensed prescriptions 90 days before surgery. Logistic regression models were used to estimate risk factors for prolonged opioid use. RESULTS: We included 5,660 patients. Postoperatively 1,584 (28%) patients were dispensed 1 or more prescriptions in Q1 and Q2 and were classified as prolonged opioid users. Among the 2,037 preoperative opioid users and the 3,623 non-opioid users, 1,201 (59%) and 383 (11%) respectively were classified as prolonged users. Preoperative opioid use, female sex, alcohol abuse, previous surgery, high Charlson Comorbidity index, and preoperative use of either antidepressants, antipsychotics, or benzodiazepines were associated with increased risk of prolonged opioid use. CONCLUSION: The incidence of prolonged opioid use was 28%. Preoperative use of opioids was the strongest risk factor for prolonged opioid use, but several other risk factors were identified for prolonged opioid use.

Risk factors for prolonged length of hospital stay following elective hip replacement surgery: a retrospective longitudinal observational study.

OBJECTIVES: Our aim was to identify which patients are likely to stay in hospital longer following total hip replacement surgery. DESIGN: Longitudinal, observational study used routinely collected data. SETTING: Data were collected from an NHS Trust in South-West England between 2016 and 2019. PARTICIPANTS: 2352 hip replacement patients had complete data and were included in analysis. PRIMARY AND SECONDARY OUTCOME MEASURES: Three measures of length of stay were used: a count measure of number of days spent in hospital, a binary measure of ≤7 days/>7 days in hospital and a binary measure of remaining in hospital when medically fit for discharge. RESULTS: The mean length of stay was 5.4 days following surgery, with 18% in hospital for more than 7 days, and 11% staying in hospital when medically fit for discharge. Longer hospital stay was associated with older age (OR=1.06, 95% CI 1.05 to 1.08), being female (OR=1.42, 95% CI 1.12 to 1.81) and more comorbidities (OR=3.52, 95% CI 1.45 to 8.55) and shorter length of stay with not having had a recent hospital admission (OR=0.44, 95% CI 0.32 to 0.60). Results were similar for remaining in hospital when medically fit for discharge, with the addition of an association with highest socioeconomic deprivation (OR=2.08, 95% CI 1.37 to 3.16). CONCLUSIONS: Older, female patients with more comorbidities and from more socioeconomically deprived areas are likely to remain in hospital for longer following surgery. This study produced regression models demonstrating consistent results across three measures of prolonged hospital stay following hip replacement surgery. These findings could be used to inform surgery planning and when supporting patient discharge following surgery.

The safety of not implementing endoscopic nasobiliary drainage after elective clearance of choledocholithiasis: a systematic review and meta-analysis.

BACKGROUND: Endoscopic nasobiliary drainage (ENBD) is used as a drainage technique in patients with choledocholithiasis after stone removal. However, ENBD can cause discomfort, displacement, and other complications. This study aims to evaluate the safety of not using ENBD following elective clearance of choledocholithiasis. METHODS: Relevant studies were identified by searching PubMed, Web of Science, EMBASE, EBSCO, and Cochrane Library from their inception until August 2023. The main outcomes assessed were postoperative complications and postoperative outcomes. Subgroup analyses were conducted based on study design types and treatment procedures. RESULTS: Six studies, including three randomized controlled trials (RCTs) and three cohort studies, were analyzed. Among these, four studies utilized endoscopic techniques, and two employed surgical methods for choledocholithiasis clearance. The statistical analysis showed no significant difference in postoperative complications between the no-ENBD and ENBD groups, including pancreatitis (RR: 1.55, p = 0.36), cholangitis (RR: 1.81, p = 0.09), and overall complications (RR: 1.25, p = 0.38). Regarding postoperative outcomes, the subgroup analysis indicated that the bilirubin normalization time was longer in the no-ENBD group compared to the ENBD group in RCTs (WMD: 0.24, p = 0.07) and endoscopy studies (WMD: 0.23, p = 0.005), although the former did not reach statistical difference. There was also no significant difference in the length of postoperative hospital stay between the groups (WMD: -0.30, p = 0.60). CONCLUSION: It appears safe to no- ENBD after elective clearance of choledocholithiasis.

Comparison between Air-Q Self Pressurized Airway Device with Blocker and Proseal Laryngeal Mask Airway in anesthetized paralyzed adult female patients undergoing elective gynecological operations.

INTRODUCTION: The Air-Q Self Pressurized Airway Device with Blocker (SP Blocker) was compared to the Proseal Laryngeal Mask Airway (PLMA) during positive pressure ventilation regarding the primary outcome (oropharyngeal leak pressure [OLP]), secondary outcomes (peak inspiratory pressure [PIP], inspired tidal volume [ITV], expired tidal volume [ETV], leak volume [LV] and leak fraction [LF]), insertion time, ventilation score, fiber-optic glottis view score, and postoperative laryngopharyngeal parameters (LPM). MATERIAL AND METHODS: Adult healthy female patients scheduled for elective gynecological laparotomies under general anesthesia using controlled mechanical ventilation were recruited to a prospective randomized comparative clinical trial. Exclusion criteria were body mass index (BMI) ≥ 35 kg m -2 , El-Ganzouri score ≥ 5, upper airway problems, hiatus hernia or pregnancy. Patients were classified into an SP Blocker group ( n = 75) and a PLMA group ( n = 75). Primary and secondary outcomes were assessed initially and at fixed time points after successful insertion of devices. RESULTS: Initially after successful device insertion: the SP Blocker group showed statistically significant higher mean OLP (cmH 2 O) (29.46 ± 2.11 vs. 28.06 ± 1.83 respectively; 95% CI: -2.037 to -0.76, P < 0.0001), lower mean PIP (cmH 2 O) (15.49 ± 0.61 vs. 17.78 ± 1.04 respectively; 95% CI: 2.02 to 2.56, P < 0.0001), higher mean ITV (mL) (411 ± 30 vs. 403 ± 15 respectively; 95% CI: -15.65 to -0.347, P = 0.041), higher mean ETV (mL) (389 ± 12 vs. 354 ± 11 respectively; 95% CI: -38.72 to -31.29, P < 0.0001), lower mean LV (mL) (22 ± 18 vs. 49 ± 10 respectively; 95% CI: 22.3 to 31.7, P < 0.0001) and lower mean LF (%) (5 ± 2.04 vs. 12 ± 6.8 respectively; 95% CI: 5.38 to 8.62, P < 0.0001) than the PLMA group. Mean insertion time (seconds) was shorter in the SP Blocker group than the PLMA group (16.39 ± 2.81 vs. 18.63 ± 3.44 respectively; 95% CI: 1.23 to 3.25, P < 0.0001). The SP Blocker group offered a better fiber-optic glottis view score than the PLMA group without differences concerning ventilation score and LPM. CONCLUSIONS: SP Blocker provided as safe anesthesia during controlled mechanical ventilation as PLMA.

Association between preoperative fasting time and clinical outcomes in surgical patients in a private general hospital.

PURPOSE: Surgical patients are routinely subjected to long periods of fasting, a practice that can exacerbate the metabolic response to trauma and impair postoperative recovery. The aim of this study was to evaluate the association between preoperative fasting time and clinical outcomes in surgical patients. METHODS: An observational, prospective study with a non-probabilistic sample that included patients of both sexes, aged over 18, undergoing elective surgeries. Data were extracted from electronic medical records, and a questionnaire was applied in 48 hours after surgery. Variables related to postoperative discomfort were assessed using an 11-point numeric rating scale. RESULTS: The sample consisted of 372 patients, and the duration of the surgical event ranged from 30-680 minutes. The incidence of nausea (26.34%) was twice that of vomiting (13.17%) and showed an association with the surgical procedure's size (p = 0.018). A statistically significant difference was observed only between pain intensity and preoperative fasting times for liquids (p = 0.007) and postoperative fasting time (p = 0.08). The occurrence of postoperative complications showed no association with preoperative fasting time (p = 0.850). CONCLUSIONS: Although no association was observed between preoperative fasting time and surgical complications, it is noteworthy that both recommended and actual fasting time exceeded the proposed on clinical guidelines.

Enhanced recovery after surgery in elective cesarean section patients with gestational diabetes mellitus does not lead to glucose-related maternal and neonatal complications.

Objective: For elective cesarean section patients with gestational diabetes mellitus (GDM), there is a lack of evidence-based research on the use of enhanced recovery after surgery (ERAS). This study aims to compare the ERAS after-surgery protocol and traditional perioperative management. Research design and methods: In this retrospective cohort study, singleton pregnancies with good glucose control GDM, delivered by elective cesarean sections under intravertebral anesthesia at least 37 weeks from January 1 to December 31, 2022, were collected at the Third Affiliated Hospital of Sun Yat-sen University. We divided all enrolled pregnant women and newborns into an ERAS group and a control group (the traditional perioperative management group) based on their adherence to the ERAS protocol. The primary outcome was the preoperative blood glucose level, with an increase of more than 1 mmol/L indicating clinical significance when compared to the control group. The secondary outcome was centered around an adverse composite outcome that affected both mothers and newborns. Results: We collected a total of 161 cases, with 82 in the ERAS group and 79 in the control group. Although the mean preoperative blood glucose level in the ERAS group was significantly higher than in the control group (5.01 ± 1.06 mmol/L vs. 4.45 ± 0.90 mmol/L, p<0.001), the primary outcome revealed that the mean glycemic difference between the groups was 0.47 mmol/L (95% CI 0.15-0.80 mmol/L), which was below the clinically significant difference of 1 mmol/L. For the secondary outcomes, the ERAS group had an 86% lower risk of a composite adverse outcome compared to the control group. This included a 73% lower risk of perioperative maternal hypoglycemia and a 92% lower rate of neonatal hypoglycemia, all adjusted by age, hypertensive disorder of pregnancy, BMI, gestational weeks, primigravidae, primary pregnancy, GDM, surgery duration, and fasting glucose. Conclusion: Implementing a low-dose carbohydrate ERAS in pregnant women with GDM prior to elective cesarean section, compared to traditional perioperative management, does not lead to clinically significant maternal glucose increases and thus glucose-related maternal or neonatal perioperative complications.

Trends in infectious adverse events after elective optical keratoplasty (PK, EK, and ALK) - Ten years' analysis from an eye bank.

PURPOSE: To report the clinical profile and donor characteristics of post-optical keratoplasty adverse events notified at an eye bank. METHODS: Between January 2013 and December 2022, 37,041 donor corneas were utilized for keratoplasty, of which 16,531 were used for penetrating keratoplasty (PK), 12,171 for endothelial keratoplasty (EK), and 1356 for anterior lamellar keratoplasty (ALK). EK included 10,956 Descemet stripping automated endothelial keratoplasty (DSAEK) and 1215 Descemet membrane endothelial keratoplasty (DMEK). The adverse events reported within the first 6 weeks of optical keratoplasty were analyzed for donor-related parameters. RESULTS: A total of 41 (0.11%) recipients had post-keratoplasty infections. Of these, 33 occurred after EK (29 after DSAEK, and four after DMEK), two after ALK, and six after PK. The clinical presentation was keratitis alone in 16 eyes and associated with endophthalmitis in 25 eyes. The organisms isolated were gram-negative bacteria in 26 eyes, fungus in eight eyes, gram-positive bacteria in four eyes, mixed infection in five eyes, and microbiology inconclusive in seven eyes. The majority (78%) of the gram-negative infections were due to multidrug-resistant organisms. Most (88%) donor corneas were harvested from hospital premises. The most common cause of donor mortality was trauma. The median duration of presentation from surgery was 4.46 (range: 1-30) days. The death to preservation time was 4.18 (1.5-7.65) hours. The death to utilization time was 3 (2-4.7) days. CONCLUSION: The overall risk of infectious adverse events after keratoplasty was 0.11%, ranging from 0.08% to 0.36%. Most (80.4%) of the adverse events occurred after EK. The majority (78.9%) of the adverse events were of bacterial etiology, of which gram-negative infections (68.4%) were the most common. The trends and microbiological spectrum of organisms associated with infections should be thoroughly documented in eye banks to gain insights and formulate guidelines on the management of adverse events.

Incidence of post-operative delirium increases as severity of frailty increases.

OBJECTIVE: The surgical population is ageing and often frail. Frailty increases the risk for poor post-operative outcomes such as delirium, which carries significant morbidity, mortality and cost. Frailty is often measured in a binary manner, limiting pre-operative counselling. The goal of this study was to determine the relationship between categorical frailty severity level and post-operative delirium. METHODS: We performed an analysis of a retrospective cohort of older adults from 12 January 2018 to 3 January 2020 admitted to a tertiary medical center for elective surgery. All participants underwent frailty screening prior to inpatient elective surgery with at least two post-operative delirium assessments. Planned ICU admissions were excluded. Procedures were risk-stratified by the Operative Stress Score (OSS). Categorical frailty severity level (Not Frail, Mild, Moderate, and Severe Frailty) was measured using the Edmonton Frail Scale. Delirium was determined using the 4 A's Test and Confusion Assessment Method-Intensive Care Unit. RESULTS: In sum, 324 patients were included. The overall post-operative delirium incidence was 4.6% (15 individuals), which increased significantly as the categorical frailty severity level increased (2% not frail, 6% mild frailty, 23% moderate frailty; P < 0.001) corresponding to increasing odds of delirium (OR 2.57 [0.62, 10.66] mild vs. not frail; OR 12.10 [3.57, 40.99] moderate vs. not frail). CONCLUSIONS: Incidence of post-operative delirium increases as categorical frailty severity level increases. This suggests that frailty severity should be considered when counselling older adults about their risk for post-operative delirium prior to surgery.

Does the Day of the Week or the Time of Day Affect the Length of Stay or Readmission Rate for Pediatric Orthopedic Admissions?

PURPOSE: Health care institutions are searching for system-wide approaches to reduce costs while maintaining quality and improving patient outcomes. Hospital length of stay (LOS) and readmission rate (RR) are variables that significantly impact health care costs. This investigation aimed to determine if there was a difference in the LOS and the RR for pediatric orthopedic patients admitted overnight or during the weekend. MATERIALS AND METHODS: We analyzed 243 admissions for pediatric orthopedic surgery cases between September 2016 and August 2018 at a single-specialty orthopedic hospital. We categorized admissions into elective surgeries, infectious etiologies, and trauma and accidents. We compared the time and day of the week of admission to the average LOS and RR. RESULTS: The mean LOS of the entire cohort was 2.93 days. The mean LOS for trauma admissions was 1.90 days, the mean LOS for elective surgeries was 3.34 days, and the mean LOS for infections was 4.11 (p = 0.00009). The mean LOS for patients admitted on a weekday was 3.00 days; the mean LOS for patients admitted on the weekend was 2.33 days (p = 0.28). The mean LOS for patients admitted between 6:00 AM and 6:00 PM was 3.12 days, and the mean LOS for patients admitted between 6:00 PM and 6:00 AM was 2.66 days (p = 0.22). The mean LOS for patients admitted during regular operating hours was 3.12 days, and the mean LOS for patients admitted during off-hours was 2.67 days (p = 0.22). The mean RR for trauma admissions was 0.0%, the mean RR for elective surgeries was 4.5%, and the mean for infections was 3.7% (p = 0.1073). The mean RR for patients admitted on a weekday was 3.2%, and the mean RR for patients admitted on the weekend was 0.0% (p = 0.37). The mean RR for patients admitted between 6:00 AM and 6:00 PM was 4.2%, and the mean RR for patients admitted between 6:00 PM and 6:00 AM was 1.0% (p = 0.15). The mean RR for patients admitted during regular operating hours was 4.2%, and the mean RR for patients admitted during off-hours was 1.0% (p = 0.14). CONCLUSION: This study showed no relationship between the day or time of admission and the LOS or RR for pediatric orthopedic admissions. Our results support the institutional goal of maintaining operations overnight and on weekends while not compromising patient outcomes.
