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 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 Trial Clinical TrialEffects of aminophylline on cognitive recovery after sevoflurane anesthesia.
Aminophylline accelerates the recovery from sevoflurane anesthesia. We studied the effects of escalating doses of aminophylline on cognitive and clinical recovery after sevoflurane anesthesia. ⋯ The administration of escalating doses of aminophylline accelerates postoperative cognitive recovery from sevoflurane anesthesia, as measured by the SOMCT, due to increased ventilatory elimination of sevoflurane.

Randomized Controlled TrialEffect of acupuncture on nausea and/or vomiting during and after cesarean section in comparison with ondansetron.
Acupuncture has been used for the management of postoperative nausea and vomiting (PONV). This study compared the effect of electrical acustimulation with ondansetron for preventing intraoperative and postoperative emetic symptoms and improving patient satisfaction. ⋯ Electrical acustimulation is comparable to ondansetron in prevention of PONV during and after cesarean delivery under spinal anesthesia and in improving patient satisfaction.
