Background: The aim of induction of labor is to initiate labor when maternal and fetal conditions necessitate delivery before the onset of spontaneous contractions. The success of this obstetric practice is highly dependent upon the condition of the cervix. Cervical ripening is a complex process that results in physical softening and distensibility of the cervix, ultimately leading to partial cervical effacement and dilatation. Objective: The purpose of the current study was to compare the effectiveness and safety of the pessary to intravaginal dinoprostone gel for induction of labor. Results: A total of 200 women were included in the study, of whom100 received dinoprostone pessary and 100 dinoprostone intravaginal gel. Tachysystole was diagnosed by the research team in 33 women, (4.5%) of those received the pessary and (2.4%) of those received gel (Table 4). In Caesarean section for suspected fetal compromise associated with uterine Tachysystole was performed in seven women in the pessary group and one in the gel group. There was no correlation between the initial Bishop score and the occurrence of uterine Tachysystole. (4.1%) women in the pessary group had a postpartum haemorrhage with estimated volume of ≥ 1000 mL compared to (2.2%) women in the gel group (P = 0.08). Conclusion: In this retrospective study, use of dinoprostone vaginal pessaries for induction of labour resulted in no advantage compared with dinoprostone intravaginal gel and clinically significant tachysystole appeared more common.
