Comparative Study
[A comparison of fentanyl and buprenorphine in total intravenous anesthesia using propofol during spinal surgery].
A retrospective study was performed to compare the hemodynamic effect and postoperative pain relief of fentanyl (Group F, n = 11) and buprenorphine (Group B, n = 11) in total intravenous anesthesia (TIVA) using propofol during spinal surgery. All patients were premedicated with midazolam (3-5 mg) i.m. Anesthesia was maintained with propofol infusion, and increments of fentanyl or single dose of buprenorphine with 40% oxygen in air. ⋯ All patients in Group F, and only two in Group B (P < 0.02) received analgesics within 20 hours. Neither nausea nor respiratory depression was found in both groups. This study suggests that buprenorphine would provide a more stable hemodynamic state and better postoperative pain relief than fentanyl in TIVA using propofol.

We report three cases in which the target-controlled propofol infusion technique was used in obese patients for general anesthesia. General anesthesia was induced by intravenous administration of fentanyl 150-300 micrograms and ketamine 50-80 mg and propofol 2 micrograms.ml-1 to achieve a target blood concentration by target-controlled infusion system. ⋯ The estimated blood concentrations of propofol at emergence from anesthesia calculated by ConGrace ranged from 1.49-1.69 micrograms.ml-1, and it took 230-300 seconds to emerge from anesthesia. The target-controlled propofol infusion technique appears useful to control the depth of anesthesia in obese patients.

Multicenter Study
[A multicenter study of cardiac events and anesthetic management of patients with ischemic heart diseases for noncardiac surgery--a follow-up report].
We have conducted a joint research project to investigate the incidence of ischemic heart disease in patients for noncardiac surgery and to define the risk of perioperative cardiac complications in these patients. From September to November 1997 we had 7288 patients scheduled to undergo noncardiac surgery in the 8 departments of anesthesiology. ⋯ In our region of Japan, 3-4% of surgical patients tend to develop ischemic heart disease and 3.1% of them demonstrated severe cardiac complications perioperatively. Compared with United States we encounter fewer surgical patients with ischemic heart disease, but the risk of developing perioperative cardiac complications in such patients is almost the same for both countries.

Biography Historical Article
[New study on the history of anesthesiology (2)--who is the first Japanese to write a scientific paper for the journal "Anesthesiology"?].
The beginning of modern anesthesiology in Japan dates back to 1950 when Dr M. Saklad of Rhode Island Hospital came to Japan to give his lectures on endotracheal anesthesia and related procedures. Since then, many Japanese surgeons visited the United States to learn anesthesiology in depth and they began to write their papers for foreign journals. ⋯ The first paper based on studies performed in Japan by Japanese authors appeared in 1956. It was entitled as "The spread of drugs used for spinal anesthesia" by Kitahara et al. This paper is the English translation of their Japanese paper which appeared in Nippon Rinsho Geka Ikai Zasshi entitled as "Basic Study on Spinal Anesthesia in 1953".

Hypertrophied lingual tonsils are rare, but may cause difficulty or inability in tracheal intubation during induction of general anesthesia. A 39-yr-old woman was scheduled for resection of symptomatic hypertrophied lingual tonsils. ⋯ However, transnasal fiberoscopic monitoring could guide the orotracheal fiber into the trachea for intubation. When an anesthesiologist can predict the abnormality of lingual tonsils, this combination might be recommended for difficult airway and intubation.
