rnal paCO2 in awake pregnant women. However, there is no evidence that this target, compared to other targets, would enable optimal conditions for the fetus during general anesthesia. Maternal paCO2 can affect uterine blood flow, affinity of hemoglobin for oxygen, and fetal CO2 elimination. In this study, a range of potential targets of maternal paCO2 was investigated in the ovine model, aiming to

. We developed a deep-learning model that reconstructs continuous mean arterial pressure (MAP) using the photoplethysmograhy (PPG) signal and compared it to the arterial line gold standard. METHODS: We analyzed high-frequency PPG signals from 117 patients in neuroradiology and digestive surgery with a median of 2201 (interquartile range [IQR], 788–4775) measurements per patient. We compared models

ypothesis that postoperative delirium is less common when neuromuscular block is reversed with sugammadex than with neostigmine combined with glycopyrrolate or atropine. METHODS: We conducted a single-center retrospective cohort study, analyzing all adult patients having general anesthesia for noncardiac surgery who received neostigmine or sugammadex from January 2016 to March 2022. Inverse propensity

Cardiac output indexed to body surface area (CI) was continuously recorded at 5-second intervals throughout surgery using a US Food and Drug Administration (FDA)-approved noninvasive monitor from the arterial

BACKGROUND Both intraoperative hypotension and excessive fluid administration can lead to detrimental perioperative complications. However, how much fluid is considered excessive and how is intraoperative hypotension related to major postoperative complications? METHODS We conducted a single-center retrospective cohort study in 6243 patients undergoing complex spine surgery at the Cleveland Clinic

BACKGROUND In elderly individuals, excessive lactate levels in the brain may be associated with the development of cognitive impairment after surgery, including delayed neurocognitive recovery (dNCR). Since the origin of this increased lactate is unknown, here we assessed associations between metabolic pathways and postoperative dNCR. METHODS This study included 43 patients (≥60 years old) who had

Efforts to deconvolve the complex interactions of cancer cells with other components of the tumor micro- and macro-environment have exposed a common tendency for cancers to subvert systems physiology and exploit endogenous programs involved in homeostatic control of metabolism, immunity, regeneration, and repair. Many such programs are engaged in the healing response to surgery which, together with

BACKGROUND Brain homeostasis imbalance, characterized by cognitive dysfunction and delirium, frequently occurs in the elderly after surgery. Investigating why this complication only affects part of patients undergoing the same surgery, and anesthesia remains intriguing. This study tested the role of preoperative blood-brain barrier (BBB) integrity in the occurrence of postoperative brain homeostasis

BACKGROUND Difficult airway management (DAM) is a challenging aspect of anesthetic care. Although nearly all DAM episodes result in successful intubation, complications are common and clinical decision-making may be complex. In adults with anticipated DAM scheduled for nonemergent surgery, we prospectively observed clinical decisions made during DAM such as awake/sedated versus anesthetized, choice

Morphine is a potent analgesic used for treating surgical and cancer pain. Despite being the drug of choice for the management of severe pain in children, the high interindividual variability in morphine pharmacokinetics limits its clinical utility to effectively relieve pain without adverse effects. This review was conducted to identify and describe all studies that have assessed the effect of genetic

BACKGROUND Compared to neuraxial anesthesia, general anesthesia (GA) for cesarean delivery is associated with an increased risk of postpartum depression (PPD) requiring hospitalization. However, obstetric complications occurring during childbirth (eg, stillbirth) are associated with both increased use of GA and increased risk of PPD, and may account for the reported association between GA and PPD.

BACKGROUND Sepsis disproportionately affects marginalized communities. This study aims to evaluate racial and ethnic disparities in failure-to-rescue (FTR) after postoperative sepsis. METHODS This cross-sectional study used data from the American College of Surgeons National Surgical Quality Improvement Program for patients who underwent inpatient noncardiac surgery between 2018 and 2021. Patients

BACKGROUND Perioperative handoffs are known to present unique challenges to safe and effective patient care. Numerous national accrediting bodies have called for standardized, structured handoff processes. Handoff mnemonics provide a memory aid and standardized structure, as well as promote a shared mental model. We set out to identify perioperative handoff intervention studies that included a handoff

. METHODS: In this single-center prospective cohort study, older noncardiac surgery patients aged 60 years and above underwent preoperative home sleep apnea testing, and pre- and postoperative delirium assessments and cognitive testing. Sleep apnea severity was determined using the measured respiratory event index (REI). Global cognitive change from before to 6 weeks (and 1 year) after surgery was

Preoperative anemia is common and associated with worse outcomes in cardiac surgery including acute kidney injury, red blood cell transfusion, cardiovascular complications, stroke, infection, and death. Patient blood management programs, which include dedicated clinical programs to diagnose and treat anemia in advance of surgery (ie, preoperative anemia programs), have been highlighted as a means to

Preoperative biofluid biomarkers reflecting pathophysiological, neuronal injury, and inflammation as well as those for Alzheimer's disease (AD) may be valuable tools for the risk stratification of perioperative neurocognitive disorders (PNDs) in older adults. We summarized current evidence relating these preoperative biomarkers to PND beyond 7 days, in older surgical participants aged ≥60 years. Studies

BACKGROUND Obstetric patient blood management (PBM) strategies were used at Corniche Hospital in 2018, initially focusing on minimizing bleeding, with other clinical strategies implemented incrementally. This study assesses program outcomes in patients with major obstetric hemorrhage of 2000 mL or greater. METHODS A retrospective study of 353 women admitted to The Corniche Hospital between 2018 and

METHODS: A total of 377 videolaryngoscopy videos from YouTube were used to create 6 varied datasets, each differing in patient diversity and image count. The study also incorporates data augmentation techniques to enhance these datasets further. Two machine-learning models, YOLOv5-Small and YOLOv8-Small, were trained and evaluated on metrics such as

We here calculate these values based on data collected from 144 participants of a previously published multicenter clinical trial investigating the effects of a single treatment with percutaneous cryoneurolysis. METHODS: In the original trial, we enrolled patients with

METHODS: This prospectively blinded feasibility study included 40 patients ranging in age from 0 to 20 years. After confirmation of lung separation by the primary anesthesia team using FOB, the sonographer and the auscultator, both blinded

itating neuraxial anesthesia complication associated with significant maternal morbidity if undertreated. In this nationwide study, we examine the racial and ethnic disparities in the inpatient utilization of EBP after obstetric PDPH in the United States. METHODS: In this retrospective observational study, we used the National Inpatient Sample, a nationally representative database of discharge records

n the public sector, the anesthetic workforce in these hospitals consists mainly of nonspecialist (general practitioner) junior doctors with limited supervision. The Essential Steps in Managing Obstetric Emergencies (ESMOE) training program for interns was introduced in 2008 to reduce maternal deaths in SA. Training is not consistently offered at all intern-training institutions and it has not been
