Comparative Study
[Remifentanil increases urine output in patients undergoing laparoscopic colectomy].
It has been reported that laparoscopic surgery increases stress response such as oliguria. We investigated whether anesthetic methods affect urine output during anesthesia in patients undergoing laparoscopic colectomy. ⋯ Adequate remifentanil injection might increase urine output by preventing stress response to laparoscopic colectomy.

Comparative Study
[Ultrasound-guided sciatic nerve block in the popliteal fossa for the postoperative pain control after Achilles' tendon repair].
To assess the usefulness of ultrasound-guided sciatic nerve block in the popliteal fossa in the postoperative pain management after Achilles' tendon repair, we compared 15 patients managed by general anesthesia and sciatic nerve block (Group B) with 17 patients managed by general anesthesia alone (Group G). The time required for the nerve block was about 20 minutes on the average, and the success rate was 100%. ⋯ Although the postoperative analgesic requirement was comparable, the time to the first postoperative analgesic administration was significantly longer in the Group B. This retrospective study suggests that ultrasound-guided sciatic nerve block in the popliteal fossa provides safe and effective postoperative pain relief after Achilles' tendon repair.

We experienced anesthesia for three cases of unilateral recurrent nerve palsy scheduled for thyroplasty type I requiring voice monitoring. The patients were sedated with dexmedetomidine and locally anesthetized. Dexmedetomidine provided sedation of high quality with natural sleep, good response to asking for phonation and very few respiratory depressions. We conclude that dexmedetomidine is an excellent sedative as a drug used for voice monitoring surgery.

We experienced a 55-year-old female patient who was diagnosed as femoral neuropathy after radical ovariectomy. An epidural catheter was introduced at T11-12 interspace without any problems and general anesthesia was induced and maintained. The operation ended uneventfully. ⋯ Those findings led us to diagnose with femoral neuropathy probably due to abdominal retractors or the operation itself, and insertion of epidural anesthesia could not be the cause of neuropathy. Her symptom was ameliorated with a conservative therapy after four months. We should perform fine neurological examinations when neurological complications occur, especially when we use epidural catheters, and also should have the knowledge about those complications.

The "BURP" maneuver (back, upward, right lateral, pressure) improves the visualization of the larynx for experienced anesthesiologists during orotracheal intubation in patients with difficult airway. We investigated whether this maneuver has same efficacy for inexperienced residents in anesthesiology. ⋯ We concluded that "BURP" maneuver was effective even for inexperienced residents. More than two months were required for the residents to develop laryngoscopy skill.
