OBJECTIVE: To investigate whether a fluid filled intra-uterine extra-amniotic Foley catheter is an effective alternative to vaginal misoprostol in inducing labor in primigravid women with post-term gestations.
PATIENTS AND METHODS: A prospective quasi-randomized controlled trial was designed and 100 primigravid women with post-term gestations were enrolled and equally allocated into two groups. A fluid filled intra-uterine extra-amniotic Foley catheter was inserted in women of group I. Women in group II received 25 microgram misoprostol vaginally every 4 h. Artificial rupture of membranes was performed for all women when their cervices reached 3-4 cm dilatation followed by oxytocin infusion if needed. The main primary outcome parameter was the induction to delivery interval. Results were tabulated and statistically analyzed.
RESULTS: No significant difference was noted in any of the demographic data between both groups. The induction to delivery interval was shorter in the Foley group (897.36 ± 116.0 vs. 960.98 ± 94.18 min; P = 0.003). There were 34 cases which needed oxytocin augmentation in group I compared to 11 cases in group II (P < 0.01). Abnormal uterine activity occurred in three cases in the misoprostol group, but none in the Foley group. Ominous fetal heart rate was noted in one case in group I but three in group II.
CONCLUSION: Fluid filled Foley catheter seems to be superior to 25 μg vaginal misoprostol regimen, when used to induce labor in primigravidae with post-term gestations with the advantage of having a shorter induction delivery interval, but more need for oxytocin augmentation.
