Biography Historical Article
[New study on the history of anesthesiology--(10). Prof. K. Shimizu and the Foundation of Japanese Society of Anesthesiology].
In August 1950, Japanese-American Joint Conference of Medical Educators was held in Tokyo and Dr Meyer Saklad of Rhode Island Hospital delivered his lectures on anesthesia. Prof. Shimizu of the Tokyo University who had just come back from the United States was asked to translate Dr Saklad's lectures. ⋯ To solve this problem, an independent society for anesthesiology was established in May 1st, 1954. Prof. Shimizu played a dominant role in the foundation of Japan Society of Anesthesiology.

Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of 8 mg and 10 mg hyperbaric bupivacaine during spinal anesthesia for cesarean section in Japanese parturients].
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. ⋯ Injection of 8 mg hyperbaric bupivacaine is preferable than 10 mg in spinal anesthesia for cesarean section to obtain adequate analgesic efficacy and to avoid maternal hypotension.

Comparative Study Clinical Trial Controlled Clinical Trial
[Evaluation of a lockable combined spinal-epidural device for use with needle-through-needle technique].
Recently, a new combined spinal-epidural (CSE) device has been introduced which allows the spinal needle to be extended a maximum of 15 mm beyond the Tuohy needle and locked onto the epidural needle after dural puncture. The aim of this study was to compare this lockable CSE device with the conventional CSE device, which allows the spinal needle to be extended 9 mm beyond the Tuohy needle, and to measure the length of the protrusion of the spinal needle beyond the Tuohy needle (top-to-top distance: TTD). ⋯ The lockable CSE device improves the success rate of spinal anesthesia in needle-through-needle CSE anesthesia.

A 67-year-old male patient with chronic tympanitis was scheduled for elective tympanoplasty. Propofol and fentanyl were used for induction and the patient was ventilated with sevoflurane, oxygen and nitrous oxide for general anesthesia. ⋯ The surgery was discontinued for the safety of the patient, in spite of the recovery of ventilation with a facemask. It is suspected that the ventilatory difficulty was caused by the following reasons; first, the laryngeal mask airway was shifted by change of the body position, second, the mask tip was inserted at the inlet of the larynx because the internal cuff pressure had risen with nitrous oxide.

Case Reports
[Total intravenous anesthesia with propofol, ketamine, and fentanyl (PFK) for a patient with mitochondrial myopathy].
Anesthetic management for a patient with mitochondrial myopathy is described. A 57 year-old-female underwent laparoscopic cholecystectomy for cholelithiasis. The patient had been diagnosed as having mitochondrial myopathy from muscle biopsy. ⋯ Her reaction to vecuronium bromide was within normal limits evaluated with a neuromuscular activity parameter, train-of-four ratio. No serious acidosis, hyperlactemia, hypothermia, nor prolonged recovery from the anesthesia was observed. As inhaled anesthetics may be contraindicated for mitochondrial myopathy, and nitrous oxide for laparoscopic surgery is relative contraindication, total intravenous anesthesia with muscle relaxant titration is appropriate for laparoscopic surgery for patients with mitochondrial myopathy.
