　概要を見る

We investigated the changes in sedative level during induction of anesthesia using a single volatile anesthetic, sevoflurane, compared with the changes when propofol and sevoflurane were used. We used a bispectral index (BIS™) monitor (Aspect, Newton, USA) to monitor the sedative level. Thirty patients were randomly divided into one group receiving sevoflurane alone (S group, n= 15) and another group receiving propofol and sevoflurane (PS group, n=15). The S group received 5% sevoflurane with nitrous oxide 6 l ·min-1 and oxygen 3 l · min-1 via a face mask, while the PS group received propofol 1.5 mg · kg-1 iv followed by step-wise increasing sevoflurane up to 5%. Induction times, as assessed by loss of eyelash reflex, were 32 s in the PS group and 65 s in the S group. The decrease in the BIS value was smooth in the S group, whereas it increased transiently and varied greatly in the PS group. Two patients in the PS group showed body movement during induction of anesthesia, and the BIS values in both cases transiently exceeded 60. BIS monitor is useful for monitoring the sedative level during induction of anesthesia, and induction using a single volatile anesthetic such as sevoflurane is smooth.

　概要を見る

A survey of unexpected cardiac arrests, excluding those associated with cardiac surgery, that had occurred during anesthesia and surgery in the period 1980-1999 was conducted. There was no significant difference between the number of such cardiac arrests that occurred in the 1980s (29/36, 159, 0.080%) and the number in the 1990s (33/37, 643, 0.088%). According to the classification by Keenan et al., there were 3 cases (0.0083%) in the 80s and 4 cases (0.0106%) in the 90s that occurred due to anesthetic management. Cardiac arrests due to surgery itself significantly decreased from 21 cases in the 80 s to 6 cases in the 90s, probably due to proper treatment for massive bleeding, a decrease in the number of cases of anaphylactic shock, and the development of novel anesthetics. Conversely, cardiac arrests due to preoperative conditions of the patients significantly increased from 5 cases in the 80 s to 23 cases in the 90s. This increase seems to be due to an increase in the number of severe and multiple injuries and an increase in complicated major surgery. The increase in number of cases due to preoperative conditions also depends on coronary spasm and cardiac conduction insufficiency. Taking into consideration the improvement in intraoperative monitoring and the development of novel anesthetics in the 90s, greater efforts should be made by anesthesiologists to reduce the incidence of cardiac arrest due to anesthetic management, and preoperative evaluation of surgical patients needs to be reconsidered.
