[Second trimester termination of pregnancy with gemeprost: a review of 306 cases]

Prostaglandin analogues provide an effective method for induction of abortion in the second trimester of pregnancy. The clinical outcome and the risk of complications were evaluated in a group of women having a medical termination of pregnancy with gemeprost.

Three-hundred and six women undergoing second trimester termination of pregnancy, between January 1998 and July 2002 in our center, were studied. All women were given 1 mg vaginal gemeprost every 3 h up to a maximum of 3 doses in the first 24 hours. If the abortion did not occur within the first 24 hours after initiation of treatment, they were given a 2(nd) course of gemeprost. Outcome measures included failure of the 1st course of gemeprost, length of hospital stay after expulsion of conceptus, heavy blood loss with or without necessity of uterine packing or blood transfusion, and failure of induction.

There was a significant difference, with better results in women with previous deliveries (vaginal or abdominal), as to the failure to abort after the 1(st) course of PG (P<0.01). Length of hospital stay, complications and failure of induction were independent from parity. Twelve (3.9%) women failed to abort with gemeprost and required other methods for abortion.

The study confirms the efficacy of gemeprost for mid-trimester termination of pregnancy, although it is a risky and costly procedure, requiring hospitalisation and is associated with higher complication rate than the first trimester surgical abortion.
