Abstract

One of the hazards of general anesthesia for cesarean section (C/S) is the risk of intraoperative awareness with or without recall of the event. We examined the relationship between auditory evoked potential index (AAI), end-tidal isoflurane concentration and hemodynamic parameters to evaluate the adequacy of our routine general anesthetic technique in C/S. This study was carried out in 70 parturients undergoing elective C/S. A standardized anesthetic technique was applied, including thiopentone and suxamethonium for induction, and O2, N2O and isoflurane for maintenance of anesthesia. AAI, heart rate, blood pressure, end-tidal isoflurane concentration and any clinical signs of inadequate depth of anesthesia such as movement, lacrimation and coughing or jerking were continuously monitored and recorded at 17 fixed time points during surgery and anesthesia. Mean arterial pressure and heart rate increased at intubation, but did not show a positive correlation with the AAI values during ...
