Induction of abortion with 15(S)-15-methyl PGF2alpha (Tham) vaginal suppositories.

The repeated administration of vaginal suppositories containing 1 mg 15(S)-15 methyl PGF2alpha (Tham) sucessfully induced abortions in 60 of 62 patients. Among patients who successfully aborted, the mean abortion time was 19.0 hours. The mean abortion time was not related to gestational age or parity. Sixty (96.8 precent) aborted within 48 hours, and 53 (85.5 percent) aborted within 24 hours. Gastrointestinal side effects occurred for 33.9 percent of the patients. Diarrhea was the most frequent side effect. The abortion was complete for 40.3 percent of the patients.

A comparison of D & C and vacuum aspiration for performing first trimester abortion.

In a study of techniques for first trimester abortion conducted at Kandang Kerbau Hospital in Singapore from September 1973 to April 1975, 420 physically healthy gravidas were randomly assigned to one of two treatment groups either by D & C or vacuum aspiration. Half of the patients in each group were 6 to 10 menstrual weeks' gestation and half were 11 to 12 week's gestation. The numbers of women with one or more complications were the same for the two treatment groups, but were significantly less when termination was carried out at 11 to 12 weeks' gestation. Estimated blood loss was significantly lower for patients treated by VA (32.3 ml) than for patients treated by D & C (39.0 ml) at 6 to 10 week's gestation, but the difference in blood loss was not statistically significant at 11 to 12 weeks' gestation. Time from insertion to removal of the speculum was significantly less with VA than D & C at 6 to 10 weeks' gestation but not at 11 to 12 weeks' gestation. Since vacuum aspiration is at least as safe as D & C, and appears to be more convenient and costeffective, it should on the basis of this experience be accepted over D & C as the standard method for treatment of first trimester abortion.

Estrogen-progesterone withdrawal bleeding in diagnosis of early pregnancy.

This study was designed to evaluate the efficacy of an exogenous estrogen-progesterone preparation for inducing "withdrawal bleeding" in non-pregnant women, a procedure used in some areas for the diagnosis of early pregnancy. Three hundred patients not desiring to be pregnant and with no signs of pregnancy other than menses delayed by 14 days or less were randomly assigned to treatment or control groups. The treatment group received an intramuscular injection of 50 mg progesterone and 3 mg oestradiol benzoate in oil. The control group received no hormonal injection. There was no significant difference between the two groups in the incidence of uterine bleeding within 7 days. Thus, the hormonal preparation was ineffective in inducing "withdrawal bleeding". Its use as a diagnostic test for pregnancy is not recommended.

A comparison of the clip and ring techniques for laparoscopic sterilization of postabortion and postpartum patients.

The spring-loaded clip and the tubal ring techniques of laparoscopic female sterilization are compared for ease of performance, safety and effectiveness at the Kandang Kerbau Hospital in Singapore. The two techniques were randomly assigned to 299 postpartum patients and 300 postabortion patients. The assigned procedure could not be performed for two of the ring cases and three of the clip cases. Bleeding and equipment problems made laparotomy necessary in two clip cases and equipment problems caused a change in technique in the other clip case. Hydrosalpinx and adhesions were responsible for a change to laparotomy in the two ring cases. Surgical difficulties, chiefly the result of equipment problems, were significantly higher for both postpartum and postabortion clip procedures. Complications and complaints reported immediately after surgery and at the 7- to 21-day follow-up visit were low for all four groups. For both postabortion and postpartum patients, six- and 12-month data show that pregnancy rates are significantly higher for patients sterilized with the clip than with tubal rings.
