Randomized Controlled TrialThe effect of patient-controlled intravenous analgesia on postoperative hypokalemia in patients undergoing laparoscopic cholecystectomy.
We investigated whether hypokalemia developed during the postoperative period and whether the use of intravenous patient-controlled analgesia (IV-PCA) could decrease the incidence of postoperative hypokalemia in patients who underwent laparoscopic cholecystectomy. ⋯ The results show that hypokalemia developed during the perioperative period and the use of IV-PCA in patients undergoing laparoscopic cholecystectomy effectively decreased the degree and incidence of postoperative hypokalemia on the day of the operation and postoperative day one.

Randomized Controlled TrialComparison of postoperative pharyngeal morbidity using the Macintosh laryngoscope or AirWay Scope after mastectomy.
We compared the characteristics of postoperative pharyngeal morbidity in intubation between the AirWay Scope (AWS) and Macintosh laryngoscope in 68 ASA I-II female patients aged 35-77 years in a randomized, double-blinded, controlled fashion. After induction of general anesthesia, the patient's trachea was intubated using the AWS or Macintosh laryngoscope by five anesthesiologists. Before leaving the operating room, postoperative sore throat, hoarseness, and dysphagia were assessed, and oral bleeding was evaluated by observation of the extubated tracheal tube. ⋯ Incidence of oral bleeding with the AWS (6.1%) was significantly lower than that with the Macintosh laryngoscope (23.5%). Pharyngeal morbidity on the day after surgery did not differ between groups, and no patient complained of delayed oral intake. In female patients, the AWS successfully reduced the incidence and severity of sore throat on the day of surgery in comparison with the Macintosh laryngoscope.

Randomized Controlled TrialIntraoperative reversal of neuromuscular block with sugammadex or neostigmine during extreme lateral interbody fusion, a novel technique for spine surgery.
Extreme lateral interbody fusion (XLIF) is a method for stabilization of the lumbar spine. Intraoperatively, the surgeon identifies the lumbar nerve roots with a stimulator to prevent their injury. The objective of this study was to determine the extent to which shallow rocuronium-induced neuromuscular block must be intraoperatively reversed for reliable identification of nerve roots. ⋯ Intraoperative reversal of shallow rocuronium-induced block with either sugammadex or neostigmine is an efficient method. For reliable detection of lumbar nerve roots with a stimulating current of 10 mA, the block should be reversed to a TOF ratio of at least 0.70. For a current intensity of 5 mA, the TOF ratio should reach 0.90.

Randomized Controlled TrialFlurbiprofen axetil enhances analgesic effect of fentanyl associated with increase in β-endorphin levels.
To examine the analgesic effect of preoperative administration of flurbiprofen axetil and that of postoperative administration of a combination of flurbiprofen axetil and fentanyl, as well as perioperative plasma β-endorphin (β-EP) levels in patients undergoing esophagectomy. ⋯ These results show that flurbiprofen axetil enhances the analgesic effect of fentanyl associated with increase in β-EP levels.
