Abstract

Study Objective: To determine the effect, if any, of a propofol-based sedation technique on the reproductive outcomes of patients undergoing embryo transfers with donor oocytes. These ova recipients form a unique subgroup, whose clinical outcomes are unrelated to direct anesthetic effects on their reproductive tracts.Design: Retrospective chart review.Setting: A 1200-bed university medical center.Patients: 117 patients who received fresh embryo transfer cycles between January 1991 and December 1995.Measurements and Main Results: The anesthesia records of 106 women who donated ova were reviewed for propofol usage during the transvaginal needle aspiration of the ova. The medical records of the 117 patients who received these donated embryos were reviewed for cumulative embryo scores, clinical pregnancy rates, and implantation rates. Fourteen patients received ova from women who were sedated with fentanyl and midazolam during ovum retrievals, while 103 patients received ova from women who had been given fentanyl, midazolam, and propofol in doses of 1.87 mg/kg to 8 mg/kg. The pregnancy rate among all patients who received ova from women who received propofol (44 of 103 = 42.7%) was 14.1 % greater than those whose ovum donors did not receive propofol (4 of 14 = 28.6). 78.6% of both propofol and nonpropofol-exposed groups had cumulative embryo scores of greater than 50. Among patients who became pregnant, 52.3% of propofol-exposed and 50% of nonpropofol-exposed cases had greater than 20% implantation rates.Conclusions: There is no evidence from our data that the administration of propofol during the aspiration of ovarian follicles for oocyte donation had a negative impact on the oocytes as measured by cumulative embryo scores, probability of a clinical pregnancy, or implantation rate.
