General anaesthesia for gamete intra-fallopian transfer.

A retrospective survey was undertaken of all patients who had gamete intra-fallopian transfer (GIFT) under general anaesthesia at this hospital over an 18-month period. Of 47 patients, 21 (44.7%) became pregnant although only 10 (21.3%) proceeded to term. All of those who proceeded to term had had enflurane as part of their general-anaesthetic technique. Although a number of the patients who received halothane became pregnant, none proceeded beyond the second trimester. It would appear that the use of halothane may be inadvisable for general anaesthesia for this procedure.
