title: Prospective, observational study of the depth of anesthesia during oocyte retrieval using a total intravenous anesthetic technique and the Bispectral index monitor.
abstract: Fifty patients scheduled to undergo IVF received a standard anesthetic of fentanyl and propofol for induction, followed by propofol infusion, with Bispectral index values and modified Ramsey sedation scores recorded at 5-minute intervals for the duration of anesthesia care. Moderate sedation was found only transiently during the first 5-10 minutes of the oocyte retrieval, but thereafter the level of sedation increased, with deep sedation and general anesthesia measured in all patients as determined by both the Bispectral index scores and lack of response to painful stimulation.
