title: Gamete intrafallopian transfer. Comparison of epidural vs. general anesthesia.
abstract: OBJECTIVE
  To investigate the reproductive outcome of laparoscopic gamete intrafallopian transfer (GIFT) performed under epidural vs. general anesthesia.
  
  
  METHODS
  Retrospective analysis of 110 consecutive laparoscopic GIFT procedures performed under general or epidural anesthesia. All patients underwent controlled ovarian hyperstimulation employing human menopausal gonadotropin and gonadotropin releasing hormone agonist, given either in the midluteal or early follicular phase. Data were retrieved concerning age, diagnosis, estradiol levels and maximum follicular diameter at the time of human chorionic gonadotropin injection, percentage of mature oocytes retrieved and number of oocytes transferred. These variables were compared using the independent means t test. Pregnancy rates and outcome between the general and epidural anesthesia groups were compared with the chi 2 test.
  
  
  RESULTS
  Of the 110 procedures, 84 were performed under general anesthesia, whereas 22 were done using epidural anesthesia. Four procedures started with epidural anesthesia and were converted to general anesthesia because of upper abdominal discomfort. The success rate of epidural anesthesia, therefore, was 85% (22/26). There were no significant differences in the confounding variables between the general and epidural anesthesia groups. However, patients receiving epidural anesthesia had a significantly higher pregnancy rate, 59.1%, and a live birth rate of 40.9% as compared to 31.0% and 21.4%, respectively, for the general anesthesia group.
  
  
  CONCLUSIONS
  Laparoscopic GIFT can be performed safely under epidural anesthesia. Because of the higher pregnancy and live birth rates, epidural is the anesthetic of choice for GIFT. However, a prospective, randomized study is needed to confirm the above observation.
