We evaluated efficacy of maximum surgical blood order schedule (MSBOS) using analysis of cross-match to transfusion ratio (C/T ratio) during 1 year after applying MSBOS to operations in our operating room. The MSBOS used was based on our trial reported in 1990. ⋯ Analysis with C/T ratio was very useful to recognize the present status of preparations of blood for surgery preoperatively. MSBOS should be re-evaluated regularly because of changes of operative environment such as surgeon, operative method, preoperative condition of patients, and so on.

We studied the protective effect of prostaglandin E1 (PGE1)-induced hypotensive anesthesia on gastric mucosa in 30 elective surgical patients. Three groups, each composed of 10 patients, received PGE1, nitroglycerin or none during general anesthesia. ⋯ In the PGE1 group the viscosity and pH increased significantly and rapidly (P less than 0.05) as compared with the other groups. This suggests that PGE1 offers prophylactic effect against postoperative acute gastric mucosal lesion (AGML).

The effects of intravenous nicardipine on the neuromuscular blockade produced by single bolus injection of vecuronium were studied in surgical patients undergoing tracheal intubation. We measured the mechanical response of the abductor pollicis muscle to stimulation of the ulnar nerve in a train-of-four sequence at 2 Hz and recorded the amplitudes of the first response (T1). Anesthesia was induced with thiopental 5 mg.kg-1 with or without nicardipine 10 micrograms.kg-1 followed by injection of vecuronium in a dose of either 0.1 or 0.15 mg.kg-1. ⋯ These values were significantly shorter than those observed in patients without nicardipine administration (n = 10, P less than 0.05), and were not significantly different from the values in patients who had received vecuronium 0.15 mg.kg-1 (n = 10). On the other hand, the time for 25% recovery in T1 was uninfluenced by nicardipine. Present study indicates that nicardipine pretreatment possibly shortens the onset time after minor or moderate dose of vecuronium.

The author designed a cart which can safely carry and accommodate Selectatec vaporizers (Ohmeda). The cart consists of ten parking brackets on which Selectatec vaporizers can be mounted and their support arms with castors. An anesthetic machine which has a Selectatec manifold allows easy removal and replacement of vaporizers, but there are several troublesome regulations regarding conveyance and accommodation of vaporizers. By the use of the cart, all these problems were completely solved and the advantage of the centralization of many vaporizers was accomplished.

Randomized Controlled Trial Comparative Study Clinical Trial
[Heat conservation during abdominal surgery].
Intraoperative hypothermia is a major problem in anesthetic management. We compared the heat conserving effect of a forced air warming system (Bair Hugger, Augustine Medical Inc.) with that of a warming blanket. Sixteen patients undergoing abdominal surgery were studied. ⋯ Temperature were measured every one hour over three hours. The BH group showed significantly higher temperatures than WB group. Bair Hugger system is an efficient way to maintain intraoperative body temperature.
