Twenty one patients who underwent prolonged surgical procedures over 10 hours under total intravenous anesthesia with droperidol, fentanyl and ketamine were studied to evaluate post-operative hepatic and renal functions as judged by serum levels of GOT, GPT, BUN and creatinine. They were divided into two groups. Ten patients of the PGE1 group were given PGE1 at a rate of 0.035 micrograms.kg-1.min-1 during anesthesia, and the remaining eleven of the control group were not given PGE1. ⋯ In both groups, post-operative s-GOT and s-GPT levels were increased significantly compared with pre-operative values, but there was no significant difference between the two groups. Serum BUN levels of the 7-10 the post-operative days were increased significantly in the PGE1 group, but those of the control group were not. These data suggest that our method of total intravenous anesthesia with droperidol, fentanyl and ketamine, when applied even for prolonged surgical procedure over 10 hours, would have beneficial effects on the post-operative hepatic and renal functions.

We investigated the roentgenogram of the epidural catheter in 82 patients in whom the injection of local anesthetics had no effect. Contrast medium 0.5 ml was injected through the epidural catheter and antero-posterior roentgenogram was taken. The roentgenograms were categorized into three patterns, according to the relationship of the catheter to the pedicle of lamina, or to the spread of contrast medium. ⋯ The catheter was thought to be misinserted intravascularly. In other 35 cases, catheter ran laterally on the pedicle of lamina, or the spread of medium 2 mins after the injection was indicated by a dumpling-shape even when the tip was in the vertebral column. In these cases, the catheter was thought not to be outside the epidural space.

A 9 year old male previously diagnosed as progressive muscular dystrophy whose serum CPK5430IU.l-1 was very high received general anesthesia. Before anesthesia, dantrolene sodium 2 mg.kg-1 was given. Anesthesia was induced with thiamylal 100 mg and vecuronium bromide 3 mg. ⋯ She was placed on a ventilator and observed carefully. The endotracheal tube was removed 150 minutes after the induction of anesthesia. In these two cases, sevoflurane and vecuronium bromide were used safely.

Ninety-nine elective abdominal surgeries were performed under high dose epidural fentanyl anesthesia. PGE1 (0.02 microgram.kg-1.min-1 = 0.02 gamma) was administered to 34 patients (0.02 gamma group), and PGE1 (0.05 gamma) was administered to 16 patients (0.05 gamma group). PGE1 was not administered to 49 patients (control group). ⋯ The forearm-fingertip temperature gradient was lower in the 0.02 gamma and 0.05 gamma groups than in the control group. The incidence of postanesthetic shivering was significantly lower in the 0.05 gamma group than in the other groups. These results suggest that; 1) PGE1 (0.02 gamma and 0.05 gamma groups) affects the peripheral blood flow and peripheral temperature, and 2) PGE1 (0.05 gamma group) significantly affects the incidence of postanesthetic shivering.

Postoperative pain relief and sedation with epidural midazolam-saline or midazolam-bupivacaine were studied in 46 patients after elective upper abdominal surgery. They were divided into 6 groups. In each group, 10 ml saline, 10 ml saline+midazolam 0.05 mg.kg-1, 10 ml saline+midazolam 0.1 mg.kg-1 (saline group), 0.25% bupivacaine 6 ml, 0.25% bupivacaine 6 ml + midazolam 0.05 mg.kg-1 or 0.25% bupivacaine 6 ml + midazolam 0.1 mg.kg-1 (bupivacaine group) was administered via epidural catheter for complaint of pain. ⋯ Midazolam level was lower than that of sedation level. There were no significant differences between saline group and bupivacaine group, but the pain relief effect was slightly stronger in bupivacaine group. It is concluded that epidural saline - midazolam or 0.25% bupivacaine - midazolam is useful for postoperative pain relief after upper abdominal surgery.
