Overtime work of anesthesiologists is associated with increased delirium in older patients admitted to intensive care unit after noncardiac surgery: a secondary analysis.

Background: Overtime work is common in anesthesiologists due to shortage of manpower. Herein, we analyzed if overtime work of anesthesiologists was associated with delirium development in older patients after surgery.

Methods: This was a secondary analysis of the database from a randomized trial.

Associations between oral frailty, oral microbiota composition, and postoperative delirium in older adult patients.

Background: Poor oral health, prevalent among the older adults, can undermine overall health and contribute to frailty. Older adults experiencing oral frailty and dysbiosis potentially face an elevated risk of postoperative delirium. This study aims to explore the influence of oral frailty and changes in oral microbiota composition on occurrence of postoperative delirium in older adult patients undergoing non-cardiac surgery.

Effect of perioperative dexmedetomidine on sleep quality in adult patients after noncardiac surgery: A systematic review and meta-analysis of randomized trials.

Background: Dexmedetomidine may improve sleep quality after surgery, but conflicting results also exist. Herein, we explored the effects of perioperative dexmedetomidine on postoperative sleep quality in adult patients.

Methods: In this systematic review and meta-analysis, randomized controlled trials investigating the effects of perioperative dexmedetomidine on sleep quality after noncardiac surgery were retrieved from Cochrane Library, PubMed, and EMBASE from inception to January 12, 2023, and updated on March 15, 2024.

Intraoperative hyperthermia is associated with increased acute kidney injury following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: a retrospective cohort study.

Background: Acute kidney injury (AKI) is common after cytoreduction surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for peritoneal surface malignancies. Herein we analyzed the association between intraoperative hyperthermia and AKI following CRS-HIPEC.

Methods: In this retrospective cohort study, we collected baseline and perioperative data from patients who underwent CRS-HIPEC mainly for pseudomyxoma peritonei between 2014 and 2020.

Study Objective: To test the hypothesis that emergence delirium might be associated with worse long-term survival.

Design: A longitudinal prospective observational study.

Setting: A tertiary hospital in Beijing, China.

Impact of mini-dose dexmedetomidine supplemented analgesia on sleep structure in patients at high risk of obstructive sleep apnea: a pilot trial.

Background: Obstructive sleep apnea (OSA) is common in surgical patients and associated with worse perioperative outcomes.

Objectives: To investigate the effect of mini-dose dexmedetomidine supplemented analgesia on postoperative sleep quality pattern in patients at high risk of OSA.

Design: A pilot randomized, double-blind, placebo-controlled trial.

Intraoperative hypotension is associated with decreased long-term survival in older patients after major noncardiac surgery: Secondary analysis of three randomized trials.

Study Objective: To assess the association of intraoperative hypotension with long-term survivals in older patients after major noncardiac surgery mainly for cancer.

Design: A secondary analysis of databases from three randomized trials with long-term follow-up.

Setting: The underlying trials were conducted in 17 tertiary hospitals in China.

Efficacy and safety of ciprofol for sedation in outpatient gynecological procedures: a phase III multicenter randomized trial.

Objective: Ciprofol (also known as cipepofol and HSK3486), is a compound similar to propofol in chemical structure and hypnotic effect. Herein we evaluated the efficacy and safety of ciprofol for sedation in outpatient gynecological procedures.

Methods: This phase III multicenter randomized trial with a non-inferiority design was conducted in nine tertiary hospitals.

Erector spinae plane block versus quadratus lumborum block for postoperative analgesia after laparoscopic nephrectomy: A randomized controlled trial.

Study Objective: We compared the analgesic effects of erector spinae plane block versus quadratus lumborum block following laparoscopic nephrectomy.

Design: A randomized controlled trial.

Setting: A tertiary hospital in Beijing, China.

Effect of Remimazolam Supplementation on Propofol Requirements During Hysteroscopy: A Double-Blind, Dose-Response Study.

Background: Propofol is commonly used for procedural sedation but may increase side effects in a dose-dependent manner. Remimazolam, an ultrashort-acting benzodiazepine, has been approved for procedural sedation but may delay awakening. This study tested the hypothesis that remimazolam as a supplement reduces effect-site propofol concentration (Ceprop) required to suppress response to cervical dilation in patients undergoing hysteroscopy.

Multimodal prevention of emergence cough following nasal endoscopic surgery under general anesthesia: a double-blind randomized trial.

Purpose: Cough during emergence from anesthesia is a common problem and may cause adverse events. Monotherapy faces uncertainty in preventing emergence cough due to individual differences. We aimed to evaluate the efficacy and safety of multimodal intervention for preventing emergence cough in patients following nasal endoscopic surgery.

Delirium in older patients given propofol or sevoflurane anaesthesia for major cancer surgery: a multicentre randomised trial.

Background: Delirium is a common and disturbing postoperative complication that might be ameliorated by propofol-based anaesthesia. We therefore tested the primary hypothesis that there is less delirium after propofol-based than after sevoflurane-based anaesthesia within 7 days of major cancer surgery.

Methods: This multicentre randomised trial was conducted in 14 tertiary care hospitals in China.

Impact of general anaesthesia on breast cancer survival: a 5-year follow up of a pragmatic, randomised, controlled trial, the CAN-study, comparing propofol and sevoflurane.

Background: Anaesthesia may impact long-term cancer survival. In the Cancer and Anaesthesia study, we hypothesised that the hypnotic drug propofol will have an advantage of at least five percentage points in five-year survival over the inhalational anaesthetic sevoflurane for breast cancer surgery.

Methods: From 2118 eligible breast cancer patients scheduled for primary curable, invasive breast cancer surgery, 1764 were recruited after ethical approval and individual informed consent to this open label, single-blind, randomised trial at four county- and three university hospitals in Sweden and one Chinese university hospital.

Mini-dose esketamine-dexmedetomidine combination to supplement analgesia for patients after scoliosis correction surgery: a double-blind randomised trial.

Background: Patients often experience severe pain after scoliosis correction surgery. Esketamine and dexmedetomidine each improves analgesia but can produce side-effects. We therefore tested the hypothesis that a mini-dose esketamine-dexmedetomidine combination safely improves analgesia.

Efficacy and Safety of Esketamine for Supplemental Analgesia During Elective Cesarean Delivery: A Randomized Clinical Trial.
