Oestrogen supplementation, mainly diethylstilbestrol, for preventing miscarriages and other adverse pregnancy outcomes.

BACKGROUND: Laboratory evidence in the 1940s demonstrated a positive role of placental hormones in the continuation of pregnancy. It was suggested that diethylstilbestrol was the oestrogen of choice for prevention of miscarriages. Observational studies were carried out with apparently positive results, on which clinical practice was based. This led to a worldwide usage of diethylstilbestrol despite controlled studies with contrary findings. OBJECTIVES: To determine the effects of antenatal administration of oestrogens, mainly diethylstilbestrol, on high risk and unselected pregnancy as regards miscarriages and other outcomes. SEARCH STRATEGY: We searched the Pregnancy and Childbirth Group Specialised Register of controlled trials in November 2002. SELECTION CRITERIA: Randomised and quasi-randomised trials were included. DATA COLLECTION AND ANALYSIS: Both reviewers extracted data from the studies identified that met the selection criteria, and the data were analysed using the RevMan software. MAIN RESULTS: Miscarriage, preterm labour, low birthweight and stillbirth or neonatal death were not positively influenced by the intervention (diethylstilbestrol) as compared to the control group. Diethylstilbestrol in utero exposure led to increased rate of miscarriage and preterm birth. There was also an increase in the numbers of babies weighing less than 2500 grams. The maternal outcome in terms of pre-eclampsia was not influenced. Exposed female offsprings have a non-significant trend towards more cancer of the genital tract and cancer other than of the genital tract. Primary infertility, adenosis of the vagina/cervix in female offsprings, and testicular abnormality in male offsprings were significantly higher in those exposed to diethylstilbestrol before birth. REVIEWER'S CONCLUSIONS: There was no benefit with the use of diethylstilbestrol in preventing miscarriages. Both short and long-term adverse outcomes in exposed offsprings were demonstration of the harm that this intervention caused women and their offspring during its usage.

Peritoneal non-closure at caesarean section.

BACKGROUND: It has been suggested that the peritoneal suture might be omitted during caesarean section without adverse effects. OBJECTIVES: The objective of this review was to assess the effects of non-closure as an alternative to closure of the peritoneum at caesarean section on intra-operative and immediate postoperative outcomes. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group trials register. SELECTION CRITERIA: Controlled trials comparing leaving the visceral and/or parietal peritoneum unsutured at caesarean section with a technique which involves suturing the peritoneum in women undergoing elective or emergency caesarean section. DATA COLLECTION AND ANALYSIS: Trial quality was assessed and data were extracted by two reviewers. MAIN RESULTS: Four trials involving 1194 women were included. Non-closure of the peritoneum saved operating time (weighted mean difference of -6.12 minutes, 95% confidence interval -8.00 to -4.27) with no significant differences in postoperative morbidity, analgesic requirements and length of hospital stay. There was a consistent, although nonsignificant, trend for improved immediate postoperative outcome if the peritoneum was not closed. REVIEWER'S CONCLUSIONS: There seems to be no significant difference in short term morbidity from non-closure of the peritoneum at caesarean section.

Rectal misoprostol in the prevention of postpartum hemorrhage: a placebo-controlled trial.

OBJECTIVE: This study investigated the effectiveness of rectal misoprostol in preventing postpartum hemorrhage. STUDY DESIGN: In a randomized, placebo-controlled study, 550 women were randomly allocated to rectally receive 400 microg misoprostol or nonidentical placebo after normal vaginal delivery. Any excessive bleeding was actively managed with conventional oxytocic agents. Blood loss was measured directly. RESULTS: The baseline variables were similar. Blood loss of > or = 1000 mL occurred in 4.8% (13/270) of the misoprostol group and 7% (19/272) of the placebo group. Additional oxytocic therapy was required by 3.3% and 4.7%, respectively. No predominance of side effects, particularly shivering, was noted in the misoprostol group. CONCLUSIONS: Postpartum use of 400 microg rectal misoprostol was well tolerated and associated with a statistically nonsignificant trend toward less postpartum hemorrhage. The early active management of excessive bleeding with conventional oxytocic agents may have reduced the potential of the study to detect differences between the groups.

Randomized comparison of rectal misoprostol with Syntometrine for management of third stage of labor.

BACKGROUND: The search for an effective, easily stored, affordable uterotonic agent in preventing postpartum hemorrhage is of importance, especially in the developing world. The objective of this study was to randomly compare the effectiveness of rectal misoprostol with Syntometrine in the management of the third stage of labor. METHODS: Four hundred and ninety-one low risk women in labor were randomly allocated to receive either misoprostol 400 microgram rectally or Syntometrine 1 ampuole intramuscularly, and postpartum blood loss was estimated as the principal end point. Comparisons were by the chi-square test or Fisher's test and relative risks with 95% confidence intervals for categorical data, and the Mann-Whitney test for ranked continuous variables. RESULTS: The baseline characteristics in terms of hemoglobin estimation in antenatal clinic, mean age, parity, and duration of labor in the 250 patients who received Syntometrine and 241 patients who received misoprostol were similar. However, there was a significant difference in the pre-delivery blood pressure of the two groups because of the non-protocol exclusion of women with elevated blood pressure allocated to receive Syntometrine. Duration of third stage of labor, blood loss postpartum and hemoglobin estimation post partum were all similar. Postpartum diastolic hypertension was more common in the Syntometrine group (p= 0.002). No other apparent side effect was noted in either group. CONCLUSION: Misoprostol rectally for management of the third stage of labor merits further investigation.
