Perioperative mortality and morbidity in Japan from Jan. 1 to Dec. 31, were studied retrospectively. Committee on Operating Room Safety of Japanese Society of Anesthesiologists (JSA) sent confidential questionnaires to 774 Certified Training Hospitals of JSA and received answers from 60.2% of the hospitals. We analyzed their answers with a special reference to the age group. ⋯ The mortality rates in these groups were 0.00, 0.00, 0.00, 0.17, 0.07, 0.05, and 1.48, and no death was found in cases under 5 years of age. The two cases of death in G group were due to too high anesthesia levels in spinal anesthesia. Other causes including overdose of anesthetics, toxic effect of local anesthetic, improper management of airway, and incompatible blood transfusion were preventable with the anesthesiologists' effort in protocol development and skilled assistance.

Case Reports
[Usefulness of epidural administration of ketamine for relief of postherpetic neuralgia].
Four patients with postherpetic neuralgia had their pain alleviated by epidural administration of ketamine. No oral non-steroidal anti-inflammatory drugs and anti-depressant drugs were effective in all cases. ⋯ When these patients stated that they did not feel pain reduced, they received epidural infusion of ketamine at doses from 5 mg to 20 mg with lidocaine or bupivacaine and their postherpetic neuralgia was controlled. Therefore with these cases, we suspect that epidural administration of ketamine, an antagonist for N-methyl-D-aspartic acid receptor, could be an effective and useful alternative treatment in a patient with refractory postherpetic neuralgia.

Case Reports
[Two patients treated with intra-aortic balloon pump counterpulsation after subarachnoid hemorrhage].
Intra-aortic balloon pump counterpulsation (IABP) was used to treat two patients with symptomatic vasospasm after subarachnoid hemorrhage. One could not tolerate triple H therapy (hypertensive hypervolemic hemodilution) because of poor cardiac function and another suffered acute myocardial infarction after aneurysm surgery followed by cardiac failure. IABP increased cerebral blood flow and prevented cerebral infarction in the former case but this could not reverse cerebral ischemia in the latter. IABP may be one choice for patients with vasospasm after subarachnoid hemorrhage.

A retrospective study was performed to determine the influence of age on hemodynamics and awakening time in total intravenous anesthesia (TIVA) using propofol and buprenorphine combined with continuous epidural anesthesia for abdominal surgery. Thirty-five patients (36-87 yr) were allocated to the following five groups by age: 36-49 yr, 50-59 yr, 60-69 yr, 70-79 yr and 80-87 yr. All patients were premedicated with midazolam i.m. ⋯ Two patients in each group required analgesics within 20 hours. Neither nausea, respiratory depression nor awareness was found. We suggest that the combination of TIVA and continuous epidural anesthesia would be useful to maintain stable hemodynamic state and to obtain early recovery time, especially in the elderly.

Case Reports
[Anesthetic management of a morbidly obese patient undergoing laparoscopic gastric bypass surgery].
We describe a successful anesthetic management of a morbidly obese patient, weighing 170 kg, height of 170 cm and body mass index of 58.8 kg.m-2, who received gastric bypass surgery performed using laparoscopic assist. After arriving in the operating room, an epidural catheter was inserted into the epidural space at the T 7-8 intervertebral space. ⋯ Anesthetic management and recovering from anesthesia were uneventful. For propofol anesthesia, infusion rates determined using the corrected body weigh, was preferable for morbidly obese patients.
