Audit of the effectiveness of cervical preparation with Dilapan prior to late second-trimester (20-24 weeks) surgical termination of pregnancy.

The aim of this audit was to evaluate the efficacy of cervical preparation with Dilapan dilators prior to late second-trimester surgical termination of pregnancy. The first audit cycle showed that after cervical preparation consisting of one or two Dilapan dilators, with or without misoprostol, on the day before or the day of the procedure, there were nine cases of cervical and uterine damage. The second audit cycle showed that cervical preparation, which consisted of two or three Dilapan dilators, on the day before the procedure improves cervical preparation and reduces the risk of damage to the uterus and cervix.
