Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of propofol and isoflurane anesthesia on postoperative nausea, vomiting and pruritus induced by epidural morphine].
We compared propofol-nitrous oxide anesthesia (Group P) with isoflurane-nitrous oxide anesthesia (Group I) on the incidence of postoperative nausea, vomiting and pruritus induced by epidural morphine. Twenty-eight patients for thoracotomy for lung surgeries were randomly assigned either to Group P or Group I. ⋯ In the late postoperative period, in Group P the incidence of nausea and vomiting tended to be low compared with Group I, but the difference was not statistically significant. The incidence of pruritus was not different between the two groups in both early and late periods.

Randomized Controlled Trial Clinical Trial
[Differences in hemodynamic effects of amrinone, milrinone and olprinon after cardiopulmonary bypass in valvular cardiac surgery].
The differences in hemodynamic effects of amrinone, milrinone and olprinone were evaluated in 46 patients for valvular cardiac surgery after cardiopulmonary bypass (CPB). Patients were randomly allocated to three groups; group A with amrinone infusion (17 patients); group M with milrinone infusion (15 patients); and group O with olprinone infusion (14 patients). Each drug was administrated as a single dose into the venous reservoir of the CPB circuit 15 min prior to the end of emergence from CPB, followed by continuous infusion. ⋯ In group M and A, the systolic blood pressure showed a significant increase after CPB. On the other hand, the systolic blood pressure showed no significant change in group O after CPB. Three drugs showed no significant difference in the dosages of catecholamines used.

We analyzed retrospectively the technical and clinical consequences of combined spinal-epidural anesthesia by needle-through-needle approach over the last two years. A Tuohy-type 18-gauge epidural needle (Perican; B. Braun Co.) and long pencil-pointed 27-gauge spinal needle (Whitacre; Becton-Dikinson Co.) were selected. ⋯ Inadequate spinal anesthesia was supplemented with epidural anesthesia in 13% of abdominal, 21% of gynecological and 7% of orthopedic cases. No serious complication occurred. We conclude that this needle-through-needle approach facilitates subarachnoid puncture with an ultra-fine spinal needle and subsequent epidural catheterization serves for supplemental and post-operative analgesia unless inappropriate subarachnoid indwelling occurs.

Comparative Study
[Comparison between total intravenous anesthesia and inhalation anesthesia in the surgery of acute cholecystitis].
We investigated retrospectively the influence of anesthetic methods on the intraoperative managements and postoperative outcomes in 26 patients receiving emergency or early surgery for acute cholecystitis. Fourteen of the 26 patients received total intravenous anesthesia with propofol, fentanyl, and ketamine (PFK group), while the remainder received nitrous oxide and isoflurane or sevoflurane anesthesia (GO group). ⋯ After surgery, the PFK group had significantly earlier bowel function than the GO group, with earlier starting of oral intake (54.0 +/- 25.1 vs 89.3 +/- 31.9 hours after surgery; P = 0.026). These data suggest that total intravenous anesthesia by propofol, fentanyl, and ketamine may provide the earlier recovery of bowel function than inhaled anesthesia after emergency or early surgery for acute cholecystitis.

Biography Historical Article
[New studies on the history of anesthesiology--a new study on Seishu Hanaoka's "Nyugan Ckiken Roku" (a surgical experience with breast cancer)].
Among Japanese physicians before the Edo era, Seishu Hanaoka is the most well known even in foreign countries as well as in Japan. His detailed biography is described in a monograph by Shuzo Kure published in 1923 which has been the most important book for the study of Seishu Hanaoka. Hanaoka had worked very hard in various fields as surgeons, educator, poet and community developer. ⋯ For these errors Shuzo Kure falsified them to be printed in his book. He even altered Chinese characters in one of the photographs of the manuscript in his book. 3) Shuzo Kure did not exhibit this manuscript at the exhibition on the occasion of 150 anniversary of Seishu Hanaoka's death in Tokyo, supposedly to avoid careful study by other investigators. All above mentioned findings strongly suggest us that the manuscript "Nyugan Chiken Roku" could be transcribed by one of Hanaoka's disciples and not by Hanaoka himself.
