Historical Article
[Yale anesthesiology: a reflection on Professor Kitahata's days].
Professor Luke Masahiko Kitahata was a professor of anesthesiology, Yale University in the United States of America. He had been employed in Yale University for 33 years, from 1964 to 1997, and acted as the chairman of the department of anesthesiology from 1973 to 1982. ⋯ The number of Japanese fellows who were trained by Professor Kitahata is more than sixty. He rendered many services for the development of anesthesiology in Japan.

Randomized Controlled Trial
[Effects of methylergometrine and oxytocin on blood loss and uterine contraction during cesarean section].
The effects of intravenous oxytocics on blood loss and uterine contraction during cesarean section were studied in 136 parturients. ⋯ Intravenous oxytocin 10 IU over 30 seconds to 15 minutes was effective to decrease blood loss and uterine contraction than intravenous methylergometrine 0.2 mg bolus.

We report on a 42-year-old oliguric uremic man on regular hemodialysis who developed sudden cardiac arrest, secondary to severe hyperkalemia, with a plasma potassium concentration of 9.7 mEq x l(-1). The cardiac arrest persisted after the initiation of cardiopulmonary resuscitation and intensive treatment for marked hyperkalemia for an hour and 55 minutes. ⋯ His cardiac rhythm was restored immediately after application of PCPS and he recovered without neurological sequelae. We therefore suggest that PCPS should be considered as a therapeutic option during cardiopulmonary resuscitation for life-threatening cardiac arrest secondary to severe hyperkalemia.

Case Reports
[Anesthetic management of corpus callosotomy with electrophysiological monitoring: a case report].
We report anesthetic management of a 5-year-old girl for corpus callosotomy indicated for the treatment of intractable epilepsy. The procedure mandated intraoperative monitoring of evoked potentials and electrocorticogram. During the first half of the surgery until the corpus callosum was exposed, anesthesia was maintained with continuous infusion of propofol. ⋯ After the completion of corpus callosotomy, we observed interhemispheric desynchronization of epileptic activities indicating successful surgical intervention. The patient emerged from anesthesia uneventfully with no neurological deficits, and thereafter with decreased incidence of generalized epileptic episodes. We suggest that such switch of anesthetic agents between propofol and sevoflurane should be helpful in intraoperative electrophysiological monitoring for ascertaining both functional preservation and successful intervention during epileptic surgery.

In this review article, hepatocyte injury by volatile anesthetics, effects of anesthetics on hepatic perfusion, protection offered by either ischemic preconditioning or anesthetic preconditioning against hepatic ischemia-reperfusion injury and effects of anesthetics on sepsis-induced hepatic injury are discussed. Halothane poses significant risk of immunologically-mediated hepatocyte injury and disturbances of hepatic blood supply. ⋯ Several animal studies demonstrate that volatile anesthetics offer more protection against ischemia-reperfusion injury than intravenous anesthetics. On the contrary, intravenous anesthetics may be more protective against sepsis-induced hepatic injury than volatile anesthetics.
