BACKGROUND: Atrial fibrillation and delirium are common complications after cardiac surgery. Both are associated with increased Intensive Care Unit (ICU) and hospital length of stay, functional decline, 30-day mortality and increase in health care costs. Obstructive Sleep Apnea (OSA) induces deleterious effects in the cardiovascular and nervous systems. We hypothesized that adult patients with preoperative OSA have a higher incidence of postoperative atrial fibrillation and delirium than patients without OSA, after cardiac surgery...

Myocardial injury is a frequent complication of surgical patients after having non-cardiac surgery that is strongly associated with perioperative mortality. While intraoperative anesthesia-related deaths are exceedingly rare, about 1% of patients undergoing non-cardiac surgery die within the first 30 postoperative days. Given the number of surgeries performed annually, death following surgery is the second leading cause of death in the United States. Myocardial injury after non-cardiac surgery (MINS) is defined as an elevation in troponin concentrations within 30 days postoperatively...

STUDY OBJECTIVE: The effect of perioperative body temperature derangement on postoperative delirium remains unclear. This study aimed to evaluate the association between intraoperative body temperature and postoperative delirium in patients having noncardiac surgery. DESIGN: Single-center retrospective observational study. SETTING: Tertiary university hospital. PATIENT: Adult patients who had major noncardiac surgery under general anesthesia for at least two hours between 2019 and 2021...

BACKGROUND: Perioperative hyperglycemia is associated with adverse outcomes in surgical patients, and major societies recommend intraoperative monitoring and treatment targeting glucose <180-200 mg/dL. However, compliance with these recommendations is poor, in part due to fear of unrecognized hypoglycemia. Continuous Glucose Monitors (CGMs) measure interstitial glucose with a subcutaneous electrode and can display the results on a receiver or smartphone. Historically CGMs have not been utilized for surgical patients...

STUDY OBJECTIVE: To determine the association between intraoperative renal tissue desaturation as measured using near-infrared spectroscopy and increased likelihood of developing postoperative acute kidney injury (AKI) in older patients undergoing hepatectomy. DESIGN: A multicenter prospective cohort study. SETTING: The study was conducted at two tertiary hospitals in China from September 2020 to October 2021. PATIENTS: 157 older patients (≥ 60 years) undergoing open hepatectomy surgery...

OBJECTIVE: The ASA physical status (ASA-PS) is determined by an anesthesia provider or surgeon to communicate co-morbidities relevant to perioperative risk. Assigning an ASA-PS is a clinical decision and there is substantial provider-dependent variability. We developed and externally validated a machine learning-derived algorithm to determine ASA-PS (ML-PS) based on data available in the medical record. DESIGN: Retrospective multicenter hospital registry study. SETTING: University-affiliated hospital networks...

STUDY OBJECTIVE: To systematically evaluate anesthesiology resident and attending perceptions of preoperative planning conversations (POPCs) and to generate understanding for improving the educational and clinical value of this practice. DESIGN: cross-sectional study. SETTING: two large Northeastern US academic residency training programs. PARTICIPANTS: clinically practicing anesthesiology residents and attendings. INTERVENTIONS: An electronic survey was administered to 303 anesthesia attendings and 168 anesthesia residents across two academic institutions between June and July 2014...

STUDY OBJECTIVE: Semaglutide is a long-acting glucagon-like peptide-1 receptor agonist used for management of type 2 diabetes and/or obesity. To test the hypothesis that perioperative semaglutide use is associated with delayed gastric emptying and increased residual gastric content (RGC) despite adequate preoperative fasting, we compared the RGC of patients who had and had not taken semaglutide prior to elective esophagogastroduodenoscopy. The primary outcome was the presence of increased RGC...

STUDY OBJECTIVE: Obstructive Sleep Apnea (OSA) is associated with increased perioperative cardiac, respiratory and neurological complications. Pre-operative OSA risk assessment is currently done through screening questionnaires with high sensitivity but poor specificity. The objective of this study was to evaluate the validity and diagnostic accuracy of portable, non-contact devices in the diagnosis of OSA as compared with polysomnography. DESIGN: This study is a systematic review of English observational cohort studies with meta-analysis and risk of bias assessment...

STUDY OBJECTIVE: It has not yet been established whether total hip arthroplasty complications are associated with anesthetic technique (spinal versus general). This study assessed the effect of spinal versus general anesthesia on health care resource utilization and secondary endpoints following total hip arthroplasty. DESIGN: Propensity-matched cohort analysis. SETTING: American College of Surgeons National Surgical Quality Improvement Program participating hospitals from 2015 to 2021...
