Randomized Controlled TrialThe analgesic effect of tramadol combined with butorphanol on uterine cramping pain after repeat caesarean section: a randomized, controlled, double-blind study.
This study aimed to explore the effect of patient-controlled intravenous analgesia (PCIA) using tramadol combined with butorphanol on uterine cramping pain in women undergoing repeat caesarean section. ⋯ The trial was registered at Chinese Clinical Trial Registry ( www.chictr.org.cn ) with ID: ChiCTR-1800014986.

Randomized Controlled TrialHigh-dose rocuronium-induced paralysis of the adductor pollicis muscle facilitates detection of the timing for tracheal intubation in elderly patients: a randomized double-blind study.
To prevent coughing related to tracheal intubation and the resultant exposure of intubating staff to the patients' expiratory aerosols, the timing of tracheal intubation needs to be precisely predicted. The aim of this study was to evaluate the hypothesis that the timing for safe tracheal intubation in elderly patients can be determined by acceleromyographically monitoring paralysis of the adductor pollicis muscle when high-dose rocuronium, given to block the respiratory muscles, is administered. ⋯ If 1 mg/kg rocuronium is administered, a TOF count of 0 acceleromyographically observed at the adductor pollicis muscle can reveal the adequate timing for tracheal intubation.

The incidence and reasons for canceled surgical cases in an academic medical center: a retrospective analysis before and after the development of a preoperative anesthesia clinic.
The development of a preoperative anesthesia clinic (PAC) can reduce the number of surgical cases canceled on the day of surgery. However, there are only a few studies on the details of cancellations in the operating room. This study aimed to assess the incidence and reasons for surgical cases canceled from admission to the operating room to the start of surgery. ⋯ The total incidence of surgical case cancellations was 0.037%. Before and after the development of a PAC, cancellation rate was comparable. After the development of a PAC, none case were canceled due to insufficient preoperative anesthetic assessment.

Case ReportsPostoperative outcomes in patients with treatment-emergent central sleep apnea: a case series.
Treatment-emergent central sleep apnea (TECSA) is a central sleep-related breathing disorder, characterized by either the persistence or emergence of central sleep apnea during the initiation of positive airway pressure therapy for obstructive sleep apnea. The purpose of this study was to review the perioperative course of patients diagnosed with TECSA. ⋯ Patients with TECSA have high rates of postoperative complications, characterized by an increased rate of unplanned intensive care admissions and both high 30-day readmission and mortality rates. When dealing with these patients perioperative physicians should implement an increased level of respiratory monitoring, and early postoperative use of their home prescribed non-invasive ventilation devices.

Randomized Controlled TrialDesflurane and sevoflurane concentrations in blood passing through the oxygenator during cardiopulmonary bypass: a randomized prospective pilot study.
Volatile anesthetics (VAs) protect myocardial cells in cardiovascular surgery. A recent clinical trial of cardiopulmonary bypass (CPB) surgery reported no significant difference in mortality rates between the use of VAs and total intravenous anesthetics at 1 year postoperatively. However, oxygenator function may affect the VA pharmacokinetics. Thus, we measured the VA blood concentrations during CPB in patients managed with four different microporous polypropylene hollow fiber membrane oxygenators. ⋯ Our results demonstrated that the blood concentrations of desflurane and sevoflurane passing through oxygenators used during CPB were similar to those in the human lung control.
