OBJECTIVES: Labor-induction methods are used in about 23% of labors. Most commonly, pharmacological methods are used to pre-induct the labor with dinoprostone - a PGE2 analog, and misoprostol - a PGE1 analog. The aim of this study was to evaluate two pharmacological methods of labor induction with the use of prostaglandins applied via an intravagi-nal insert containing misoprostol at a dose of 0.2 mg and intracervical gel containing dinoprostone at a dose of 0.5 mg. MATERIAL AND METHODS: This retrospective study was conducted on a group of 50 adult patients qualified for the pre-induction of labor. Following data were recorded: the time from the drug administration to the beginning of regular contractile function, the time from administration to amniotic fluid rupture, the time from medicament administration to the vaginal labor or caesarean section, the duration of I, II and III stages of labor, the delivery method and in the event of caesarean section - the indications for surgery. RESULTS: In comparison to dinoprostone, the misoprostol application was found to shorten the time from drug administration to amniotic fluid rupture by 14.1 hours, the time to the beginning of the first stage of labor by 11.7 hours and from the drug administration to the delivery by 17.3 hours (p-value < 0.05). The duration of the first stage of labor in the misoprostol group was shorter by 1.2 hours than in dinoprostone group (p-value < 0.05). CONCLUSIONS: Application of intravaginal insert with misoprostol at a dose of 0.2 mg appears to be a more effective method of labor induction in comparison to intracervical gel with dinoprostone at a dose of 0.5mg. Thorough analysis of these methods requires further studies.
