The aim was to review of cases of induction of labor and to identify rate, methods, and outcome in primigravidae and multigravidae. Materials and Methods: This was a retrospective study of medical charts review of cases of induction of labor-managed at King Abdulaziz University Hospital. During the study period 2,583 delivered and 150 cases had induction of labor. Patients details, clinical presentations, diagnosis, gestational age, method of induction, and mode of delivery identified, and outcomes were recorded. Results: During the study period 2,583 delivered in this institution and a total number of cases admitted for induction were 151 cases. The rate of induction was 5.8%. The range of age 19 to 46 years with a mean of 29.9 ± 5.87 years. The range of gravidity was 1 to 14 with a mean of 2.9 ± 2.14. The range of gestational age was 27 to 43 weeks with a mean of 39.3 ± 2.72 weeks. Only 15.2% had cesarean section and 88.8% of multigravidae and of 77.4% primigravidae had vaginal delivery. Vaginal dinoprostone was given in 69.5% and oral misoprostol in 30.5%. In 26.63% of cases oxytocin was added. Bishop score were less than 3 in all cases. Age, gestational age, and duration was statistically significant in primigravidae vs. multigravida with a p value < 0.05. The mode of delivery here was statistically different between the two group with a p value < 0.035. The admitting diagnosis for induction of labor in 28.5% of cases were postdated, 19.9% were GDM or 11.9% hypertensive patients, and only 6.6% were PROM. The others were only 17 cases, induced due to chronic medical illness. No statistically significant difference in fetal weight was seen with a p value < 0.966, and with an Apgar score at five minutes or NICU admission or maternal complications. Apgar score at one minute was less than 7 in primigravidae more than multigravidae, with a p value < 0.017, as well as the number of patents who had episiotomy with a p value < 0.001. Conclusion: Induction of labor is beneficial and safe, even with low Bishop score less than 3; the rate of failure and outcome are similar in both primigravidae and multigravidae.
