Postoperative nausea and vomiting (PONV) remains one of the most common and distressing adverse events after anesthesia and surgery, with important effects on patient comfort, recovery quality, discharge readiness, and healthcare resource use. Although advances in anesthetic techniques, antiemetic pharmacology, and enhanced recovery pathways have improved perioperative care, PONV continues to occ…

ObjectiveThe aim of this study was to determine the median effective dose (ED50) and 95% effective dose (ED95) of fospropofol disodium required to suppress the cough response during tracheostomy tube exchange in patients with disorders of consciousness receiving a background dose of sufentanil 5 μg/kg.MethodsTwenty-nine patients with disorders of consciousness requiring general anesthesia for sur…

For anesthesiology residents working 24-hour shifts, providing brief, scheduled "nap opportunities" may lead to better clinical performance, reports a clinical trial in the October 2026 issue of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA).

The American Society of Anesthesiologists (ASA) today announced the continuation of its longstanding collaboration with Masimo, a Danaher company and a specialty diagnostics solutions innovator of pulse oximetry and other patient-monitoring solutions, through ASA's Corporate Supporter Program. Now in its 14th year, the relationship supports education and initiatives designed to advance anesthesia…

BackgroundNorepinephrine is an effective vasopressor for preventing and managing spinal anesthesia-induced hypotension during cesarean delivery. Nevertheless, data regarding the 95% effective dose (ED95) of continuous norepinephrine infusion in obese parturients remain scarce.MethodsThis prospective dose-finding study enrolled parturients scheduled for elective cesarean delivery under spinal anes…

BackgroundPostoperative neurocognitive disorder (PND), including postoperative delirium (POD) and postoperative cognitive dysfunction (POCD), are prevalent and debilitating complications in elderly surgical patients. Remimazolam, a novel ultra-short-acting benzodiazepine with favorable hemodynamic and sedative properties, has not been fully evaluated for its impact on PND.MethodThis systematic re…

In response to reported medication errors that harmed patients in Nashville, the Society for Obstetric Anesthesia and Perinatology (SOAP), the Anesthesia Patient Safety Foundation (APSF) and the American Society of Anesthesiologists (ASA) today reaffirmed that spinal anesthesia remains a safe and essential anesthetic technique when administered with appropriate medication. These devastating event…

BackgroundAnticholinergic drugs are commonly used as premedication in clinical practice. The effects of premedication of atropine, penehyclidine, and glycopyrrolate on postoperative delirium in older patients remain unclear.ObjectiveThe aim of this study was to observe the effects of premedication with atropine, penehyclidine, and glycopyrrolate on postoperative delirium (POD) in older patients u…

IntroductionSepsis remains a significant clinical challenge characterized by complex inflammatory responses and hemodynamic instability, often modeled via cecal ligation and puncture (CLP). This study investigated the cardiovascular impacts of various anesthetic protocols in spontaneously hypertensive rats (SHR) subjected to abdominal sepsis.MethodsSeptic SHR were allocated into five anesthetic g…

BackgroundPerioperative stress and immunosuppression may influence tumor recurrence and long-term survival in cancer patients. Dexmedetomidine, a widely used anesthetic adjunct, remains controversial regarding its impact on postoperative prognosis. Some studies suggest it may attenuate immunosuppression, whereas others point to a potential tumor-promoting effect. This meta-analysis aimed to synth…

Women carrying breech babies have a better chance of avoiding a cesarean delivery (C-section) when spinal or epidural anesthesia is used during external cephalic version (ECV), a procedure used to turn the baby head-down before labor, according to the American Society of Anesthesiologists (ASA).

Ketamine given during C-sections could help ease early symptoms of postpartum depression. Common pain relievers, such as ibuprofen, may reduce the risk of delirium after surgery.

Ketamine given during C-sections could help ease early symptoms of postpartum depression. Common pain relievers, such as ibuprofen, may reduce the risk of delirium after surgery. Patients who take sleep medication before surgery may sleep better, have less pain and use fewer opioids after surgery. And cannabis use may increase the risk of a heart attack around the time of surgery but lower the ri…

BackgroundKetamine gargle is considered a highly effective measure for preventing postoperative sore throat (POST). This randomized controlled study aimed to explore the efficacy, safety, and optimal dosage of esketamine gargle for preventing POST following laryngeal mask airway insertion.MethodsA total of 150 patients were randomly assigned to receive normal saline (NS), 25 mg, or 50 mg of esket…
