Stress hormone response was investigated during midazolam/fentanyl/oxygen/air anesthesia combined with epidural anesthesia in six patients undergoing abdominal total hysterectomy (group MF). A control group of six patients received nitrous oxide/oxygen/sevoflurane anesthesia combined with epidural anesthesia (group C). We evaluated plasma concentrations of ACTH, cortisol, aldosterone and beta-endorphin during the control period, 10 min, 60 min after incision, and in the recovery room. In group C, plasma concentrations of ACTH, cortisol, aldosterone and beta-endorphin increased significantly 60 min after incision compared with control concentrations. But in group MF, they did not increase significantly during anesthesia. In the recovery room there were significant differences compared with preinduction concentrations in both groups. It is concluded that midazolam/fentanyl anesthesia combined with epidural anesthesia is more effective than nitrous oxide/oxygen/sevoflurane anesthesia combined with epidural anesthesia to control the stress response to surgery.
