Randomized Controlled Trial
[Efficacy and safety of remifentanil-based regimen for postoperative pain management in abdominal surgery patients: a double-blind study with low-dose remifentanil infusion of 0.02 microg x kg(-1) x min(-1)].
Remifentanil is a powerful analgesic with fast onset and ultra-short duration of action. Its context-sensitive half-time is consistently short even after a prolonged infusion. Remifentanil is effective for providing better postoperative analgesia, but this method is not generally accepted in Japan. The present study was conducted to document efficacy and safety of low-dose remifentanil infusion in postoperative patients. ⋯ Remifentanil infusion at 0.02 microg x kg(-1) x min(-1) can safely be used without any serious adverse events, while it may not be enough for postoperative analgesia. The best dosage of this drug for postoperative analgesia remains to be elucidated.

Randomized Controlled Trial
[Effect of concentration on counting numbers on pain induced by injection of propofol].
One of the concerns in the use of propofol is the pain on injection of the drug. Many attempts were made to prevent such pain, none of which has been reasonably successful. We hypothesized that the pain is attenuated when the patient is directed to concentrate on counting numbers while propofol is injected. ⋯ Intensive counting did not reduce the incidence of pain on injection of propofol. Age and the degree of pain on inserting intravenous cannula can be a useful predictor for an intolerable pain on injection of propofol.

Randomized Controlled Trial
[Analgesic efficacy and clinical safety of intraperitoneal instillation combined with rectus sheath block using ropivacaine for pain relief after laparoscopic gynecological surgery].
The aim of this study was to evaluate the analgesic efficacy and safety of rectus sheath block combined with intraperitoneal instillation using two doses of ropivacaine in patients undergoing laparoscopic gynecological surgery. ⋯ The present study showed that the combination of rectus sheath block with intraperitoneal instillation of ropivacaine was safe and potent enough to relieve pain after laparoscopic surgery.

Randomized Controlled Trial Comparative Study
[Comparison of the efficacy of ropivacaine and that of levobupivacaine for postoperative epidural analgesia in patients undergoing gynecological open abdominal surgery].
Postoperative analgesia is important in patients undergoing open abdominal surgery. We prospectively compared the efficacy of ropivacaine and that of levobupivacaine for postoperative epidural analgesia in patients undergoing gynecological open abdominal surgery. ⋯ Both 0.187% ropivacaine and levobupivacaine similarly provide appropriate postoperative epidural analgesia for patients undergoing gynecological open abdominal surgery.

Randomized Controlled Trial Comparative Study
[Comparison of Pentax-AWS, GlideScope Cobalt, and Macintosh laryngoscope in patients for nasotracheal intubation].
We compared the time for instrumentation in nasotracheal intubation using Pentax-AWS and Glidescope to that using the Macintosh laryngoscope in patients with normal airway. ⋯ When operated by experienced anesthesiologists, both Pentax-AWS and Glidescope showed similar performance for nasotracheal intubation compared with Macintosh laryngoscope in normal airway patients.
