[Postoperative pain management using subcutaneous fentanyl and ketamine after abdominal gynecologic surgery].

Background: Subcutaneous opioid is one way of managing postoperative pain in patients undergoing anticoagulant therapy. We have evaluated the safety and the efficacy of postoperative pain management using subcutaneous fentanyl and ketamine after abdominal gynecologic surgery.

Methods: Written informed consent was obtained from 50 ASA physical status 1 or 2 female patients aged between 20 and 65.

[Comparison of 8 mg and 10 mg hyperbaric bupivacaine during spinal anesthesia for cesarean section in Japanese parturients].

Background: Hypotension after spinal anesthesia for cesarean section is common and may result in serious complications despite the use of uterine displacement and volume preloading. Adequate amount of hyperbaric bupivacaine for Japanese parturients whose frames are generally smaller than those of Caucasian counterparts have not yet been examined. We compared the analgesic efficacy and the incidence of hypotension with 8 mg versus 10 mg hyperbaric bupivacaine during spinal anesthesia for cesarean section in Japanese parturients.

[Anesthetic factors that influence pH of neonatal umbilical artery from mothers in severe gestosis during cesarean section under sevoflurane anesthesia].

Twenty-two patients complicated with severe gestosis underwent cesarean section. General anesthesia was induced with intravenous thiopental and suxamethonium and maintained with sevoflurane below 1.5% with 40-50% oxygen and 50-60% nitrous oxide.
