We evaluated the effects of intraoperative remifentanil dosage on postoperative analgesic consumption in 106 patients undergoing CPA tumor removal with propofol-remifentanil anesthesia. The low-dose group was defined as total intraoperative remifentanil dosage/body weight/surgical duration <0.66μg/kg/min (n=61), and the high-dose group as ≥0.66μg/kg/min (n=45). In the low-dose group, the number of patients who required postoperative analgesics gradually decreased, while that in the high-dose group remained high from postoperative day (POD) 1 to POD 3. There were no differences in the number of patients who did not require any postoperative analgesics from POD 1 to POD 3 between the low- and high-dose groups. In addition to intraoperative high dose remifentanil, the younger patient age was a factor that prolonged the postoperative analgesic consumption.
