Postoperative nausea and vomiting (PONV) is an undesirable complication in patients undergoing general anesthesia. Combination therapy via different mechanisms of action for antiemetic prophylaxis has been warranted for effective treatment of PONV. This study was designed to compare the prophylactic antiemetic effect between midazolam combined with palonosetron (group MP) and palonosetron alone (group P) after laparoscopic cholecystectomy surgeries. ⋯ In the prevention of PONV, midazolam combined with palonosetron, administered during induction of anesthesia was more effective as compared to palonosetron alone.

Postoperative delirium (PD) remains an issue in cardiac surgery despite the constant efforts to reduce its incidence. In this retrospective study, the incidence of PD was evaluated in patients who underwent cardiac surgery with cardiopulmonary bypass (CPB) according to different primary anesthetic agents: sevoflurane and dexmedetomidine- versus propofol-based anesthesia. A total of 534 patients who underwent heart-valve surgery or coronary artery bypass graft surgery with CPB between January 2012 and August 2017 were divided into 2 groups according to the main anesthetic agent: sevoflurane with dexmedetomidine (sevo-dex group, n = 340) and propofol (propofol group, n = 194). ⋯ Older age, lower preoperative albumin levels, and emergency surgery were significant risk factors for PD. The overall incidence of PD after cardiac surgery with CPB did not differ between patients receiving sevoflurane and dexmedetomidine-based versus propofol-based anesthesia. Only hyperactive PD occurred less frequently in patients receiving sevoflurane and dexmedetomidine-based anesthesia.

Comparative Study
Risk factors of delayed recovery from general anesthesia in patients undergoing radical biliary surgery: What can we prevent.
Delayed recovery (DR) is very commonly seen in the patients undergoing laparoscopic radical biliary surgery, we aimed to investigate the potential risk factors of DR in the patients undergoing radical biliary surgery, to provide evidences into the management of DR. Patients who underwent radical biliary surgery from January 1, 2018 to August 31, 2020 were identified. The clinical characteristics and treatment details of DR and no-DR patients were compared and analyzed. ⋯ There were significant differences on the duration of surgery, duration of anesthesia, and use of intraoperative combined sevoflurane inhalation (all P < .05), and there were not significant differences on American Society of Anesthesiologists, New York Heart Association, tumor-lymph node- metastasis, and estimated blood loss between DR group and control group (all P > .05). Multivariable logistic regression analyses indicated that age ≥70 years (odd ratio [OR] 1.454, 95% confidence interval [CI] 1.146-1.904), body mass index ≥25 kg/m2 (OR 1.303, 95% CI 1.102-1.912), alcohol drinking (OR 2.041, 95% CI 1.336-3.085), smoking (OR 1.128, 95% CI 1.007-2.261), duration of surgery ≥220 minutes (OR 1.239, 95% CI 1.039-1.735), duration of anesthesia ≥230 minutes (OR 1.223, 95% CI 1.013-1.926), intraoperative combined sevoflurane inhalation (OR 1.207, 95% CI 1.008-1.764) were the independent risk factors for DR in patients with radical biliary surgery (all P < .05). It is clinically necessary to take early countermeasures against various risk factors to reduce the occurrence of DR, and to improve the prognosis of patients.

Studies on perioperative cardiac arrest in Chinese hospitals have rarely been retrieved from international journals. This survey evaluated the incidence, causes, and outcomes of perioperative cardiac arrests in a Chinese tertiary general hospital between July 2013 and December 2020. The incidence of cardiac arrest within 24 hours of anesthesia administration was retrospectively identified using an anesthesia database in Liaocheng People's Hospital. ⋯ There were 9 anesthesia-related deaths (0.8:10,000), all of which were partially related to anesthesia. Perioperative cardiac arrests were correlated with age, gender, ASA grade and surgical procedures. The 2 most important patient factors leading to cardiac arrest were hemorrhagic shock from trauma and septic shock, respectively.

Review Case Reports
Unusual Manifestations of the Trigeminocardiac Reflex During Awake Craniotomy: A Case Report and Review of the Literature.
The trigeminocardiac reflex (TCR) is triggered by stimulation of a branch of the trigeminal nerve and results in vagally mediated bradycardia, hypotension, apnea, and gastrointestinal hypermotility. In the operating theatre, patients susceptible to TCR are typically under general anesthesia; thus, cardiac abnormalities are the most common manifestation. Our case highlights the less common intraoperative manifestations of gastric hypermotility and apnea in a patient undergoing awake craniotomy for tumor resection. Prompt recognition, removal of stimuli, and airway management prevented catastrophic complications while facilitating completion of the procedure.
