Abstract:
Objective To evaluate the performance of the target controlled infusion(TCI) system with midazolam during combined spinal and epidural anesthesia. Methods Twenty female patients scheduled for selective lower abdominal or pelvic surgery under combined spinal and epidural anesthesia were enrolled in this study. They use combined spinal and epidural anesthesia with target controlled infusion of midazolam sedation. Midazolam plasma concentration was set at 100ng/ml. Blood pressure,heart rate, pulse oxygen saturation were monitored during anesthesia and operation. We use BIS as a pharmacodynamic value of midazolam sedation. Blood samples were taken from radial arterial for analysis of plasma midazolam concentration during infusion. Midazolam plasma concentration were tested by high performance liquid chromatography. Results MDPE of target controlled infusion with midazolam with Burher parameters was 38.7%, MDAPE was 38.7%,and wobble is 24.9% in Chinese female patients. Conclusions Burher parameters of midazolam target controlled infusion system should be correct, then can be used for our country female patients conscious sedation accurately.
