Randomized Controlled Trial
[Effects of rikkunshito on the postoperative nausea and vomiting (PONV) after laparoscopic gynecological surgery].
Postoperative nausea and vomiting (PONV) is one of unignorable complications after general anesthesia. The aim of this study was to examine prophylactic effects of TSUMURA rikkunshito (TJ-43), a herbal medicine consisting of eight herbs, on PONV after laparoscopic surgery. ⋯ Perioperative administration of TJ-43 showed a possible effectiveness to reduce the severity of PONV and to promote earlier recovery of oral meal intake after gynecological laparoscopic surgery.

Comparative Study
[Comparison of the Pentax-AWS and Fineview video laryngoscopes in the ease of laryngoscopy in 50 patients].
We compared the Pentax-AWS and Fineview video laryngoscopes in the ease of laryngoscopy in 50 patients. ⋯ We conclude that the view of the glottis obtained using the Pentax-AWS was significantly better than the view obtained with the Fineview.

Difficult airway management (DAM) is one of the most important issues for anesthesiologists. The DAM practical seminar was held for the purpose of improving skill and ability for decision-making to the anesthesiologist's DAM. ⋯ The DAM practical seminar in the hospital is useful not only for perioperative team practice training, but also for improving the emergency call system.

Comparative Study
[Comparison of three kinds of less invasive cardiac output measuring systems in aged patients].
Recently, the number of operations for aged patients have been increasing. They usually have various preoperative complications especially cardiovascular systems, and cardiac output measuring under general anesthesia is useful for their operative managements. The aim of this study was to compare the accuracy of three kinds of less invasive equipments for cardiac output measurements, i.e. the impedance cardiography (ICG), the partial CO2 rebreathing (NICO), and the arterial pressure-based cardiac output (APCO). ⋯ Three kinds of less invasive cardiac output measurement systems have enough functions to use during surgery for aged patients.

Case Reports
[Severe hypotension as a complication of intramyometrial injection of vasopressin: a case report].
A thirty-year-old woman was scheduled for laparoscopic myomectomy. After insertion of an epidural catheter at the L4-5 interspace, general anesthesia was induced with thiopental 250 mg followed by vecuronium 8mg intravenously to facilitate tracheal intubation. General anesthesia was maintained with sevoflurane and nitrous oxide. ⋯ To decrease blood pressure and heart rate, we increased inspiratory concentrations of sevoflurane and nitrous oxide and administered local anesthetics via epidural catheter, and hemodynamic parameters became gradually stable. We estimate that severe hypotension observed in this case is associated with intramyometrial injection of vasopressin. Increased blood concentration of vasopressin might cause vasoconstriction of coronary artery, increases in afterload, and/or direct myocardial depression resulting in decreased cardiac output.
