Abstract

Abstract: Objectives: The primary objective of our study was to ascertain whether moistening the Brazilian formulation of vaginal misoprostol tablets increases cervical dilation before manual vacuum aspiration (MVA), compared with use of dry misoprostol, in first-trimester miscarriage. The secondary objective was to ascertain whether there was any correlation between vaginal pH and the degree of cervical dilation using a moistened or dry misoprostol tablet. Methods: In a single-centre, double-blind, randomised trial, 46 patients with first-trimester miscarriage were randomly allocated to treatment with dry or moistened (with 200 µl distilled water) 2 × 200 μg misoprostol tablets. Results: The median (range) cervical dilation in the wet and dry groups was 8 mm (6–12 mm) and 7 mm (5–10 mm), respectively ( p = .06). The median time between misoprostol insertion and carrying out the procedure did not differ between the dry (406 min, range 180–550 min) and wet (448 min, range 180–526 min) groups ( p = .1). No correlation was found between vaginal pH and cervical dilation using continuous data ( p = .57; r= 0.08; 95% confidence interval −0.02, 0.3) or dichotomous data (pH ≤5/>5; cervical dilation ≥8 mm or <8 mm; p = .8). Conclusion: No difference was observed in cervical dilation between moistened and non-moistened misoprostol use prior to MVA.
