RESUMEN
This is the protocol for a Campbell systematic review. The objectives are as follows: Our proposed systematic review and meta-analysis will integrate the evidence available from all sources to answer the following questions: (1) to what extent can information, behavioral and monetary interventions reduce energy consumption of households in residential buildings? (average treatment effect of interventions) (2) what is the relative effectiveness of interventions? (account for heterogeneity in treatment effects across and within studies) (3) how effective are combinations of different interventions?
RESUMEN
OBJECTIVE: To evaluate the efficacy of high-dose oral misoprostol for mid-trimester pregnancy interruption. METHODS: We reviewed our experience with high-dose oral misoprostol for mid-trimester pregnancy interruption from November 1995 to May 1999. Patients undergoing labor induction for intrauterine fetal demise or medically indicated pregnancy termination at 13-32 weeks of gestation with a non-dilated cervix were evaluated. Patients received 400 microg misoprostol orally every 4 h. Women undelivered within 24 h were considered failures and were treated with high-dose oxytocin as previously described. For comparison, a group of women treated with high-dose oxytocin were evaluated. RESULTS: Forty-seven pregnancies were managed with misoprostol (n = 23) or high-dose oxytocin regimen (n = 24). Both groups were similar with respect to induction indication, gestational age, maternal age/parity, laminaria use, and initial cervical dilation. Induction-to-delivery interval (mean +/- SD) was significantly shorter in the misoprostol cohort (15.2 +/- 6.7 h) compared with those treated with oxytocin (21.7 +/- 11.0 h; p = 0.02). Additionally, a significantly greater percentage of women treated with misoprostol delivered within 24 h (91.0%) compared with the oxytocin group (62.0%; p = 0.04). Adverse outcomes and side effects were not significantly different between the study groups. CONCLUSION: High-dose oral misoprostol is more effective than concentrated oxytocin infusion for mid-trimester pregnancy interruption.
