Randomized Controlled TrialProgrammed intermittent epidural bolus for post-cesarean delivery analgesia: a randomized controlled double-blind trial.
The aim of this study was to assess the efficacy of programmed intermittent epidural boluses (PIEB) in postoperative pain management compared with continuous epidural infusion (CEI) after cesarean delivery. ⋯ Postoperative epidural analgesia for patients who underwent cesarean delivery with PIEB compared with CEI resulted in less ropivacaine usage while providing comparable analgesia.

Randomized Controlled TrialInvestigation of the optimal method of oxygen administration with simultaneous use of a surgical mask: a randomized control study.
From the perspective of infection prevention during the Coronavirus disease 2019 (COVID-19) pandemic, a recommendation was made to use surgical masks after extubation in patients in the operating room. For compliance with this recommendation, anesthesiologists need to administer oxygen to the patient with an oxygen mask over the surgical mask. However, no studies have investigated whether this method allows good maintenance of oxygenation in patients. This study aimed to investigate which method of oxygen administration lends itself best to use with a surgical mask in terms of oxygenation. ⋯ Wearing a surgical mask over the nasal cannula during oxygen administration is beneficial for oxygenation and might help prevent aerosol dispersal.

Randomized Controlled TrialPenehyclidine for prevention of postoperative nausea and vomiting following bimaxillary orthognathic surgery: a randomized, double-blind, controlled trial.
To investigate the efficacy and safety of low-dose bolus plus continuous infusion of penehyclidine in preventing postoperative nausea and vomiting (PONV) following bimaxillary surgery. ⋯ A low-dose bolus plus continuous infusion of penehyclidine was effective in preventing PONV without increasing emergence agitation.

Randomized Controlled TrialSafety and efficacy of an automated anesthesia delivery system for total intravenous anesthesia with propofol, remifentanil, and rocuronium: a non-inferiority randomized controlled trial versus manually controlled anesthesia.
We have developed an automated anesthesia control system that uses biological information to provide closed-loop control of drug administration for total intravenous anesthesia with propofol, remifentanil, and rocuronium. In this study, we investigated whether the control of sedatives, analgesics, and muscle relaxants delivered by this system is non-inferior to that delivered by anesthesiologists. ⋯ The clinical use of our automated anesthesia control system should allow for the maintenance of adequate anesthesia by adjusting the doses of intravenous anesthetics in the same way as anesthesiologists do.

Randomized Controlled TrialThe relationship between core temperature and perioperative shivering during caesarean section under intrathecal anesthesia with bupivacaine and ropivacaine: a randomized controlled study.
To assess the incidence rate of perioperative shivering for cesarean section and explore the associations between the occurrence of shivering and hypothermia, core temperature change, local anesthetic. ⋯ In our study, for cesarean section, the occurrence of shivering was associated with the local anesthetics and the change of core temperature after SA, while not the hypothermia.
