Abstract

Background: Spontaneous rupture of membranes is a common phenomenon in the labor process but remains one of the key issues in obstetric practice. Assessing the risk of complications due to delayed termination of pregnancy in cases of spontaneous ruptured membranes with a cervix ≤3cm plays a significant role, thereby helping to indicate the appropriate method of pregnancy termination. The objective of the study is to evaluate the relationship between some factors and the method of pregnancy termination in the above group of patients. Objectives:1. Describe the clinical characteristics, ultrasound findings, and the rate of cesarean section after rupture of membranes. 2. Investigate some factors related to the rate of cesarean section. Materials and method: The study involves pregnant women with a gestational age ≥ 37 weeks, experiencing rupture of membranes with a cervical dilation ≤ 3 cm, who were admitted to and terminated of pregnancy at the Can Tho Obstetrics and Gynecology Hospital. The research method used is a case series report. Results: The cesarean section rate after rupture of membranes was 43.3%. The majority of patients were aged 25-34 years (43 cases, accounting for 47.8%); the cesarean section rate was higher in the group aged < 35 compared to those aged ≥ 35 (OR=1.91, CI 95% 0.34-10.06; p = 0.44). Most of the cases were primiparous (47 cases, accounting for 70.1%; the cesarean section rate was higher in primiparous women compared to multiparous women, with a statistically significant difference (OR = 4.17, CI 95% 1.21-14.36, p = 0.018). There were 18 cases with an AFI ≤ 5 (20%). The cesarean section rate was 3 times higher in the group with a Bishop score ≤ 3 compared to the group with a Bishop score ≥ 4 (p = 0.009). Conclusion: Primiparous and a Bishop score of 0–3 were associated with a higher risk of cesarean section in cases of ruptured membranes with a cervix ≤ 3 cm.
