EVALUATION OF LABOR INDUCTION OUTCOME USING A MODIFIED DOUBLE-BALLOON FOLEY CATHETER AT SOC TRANG HOSPITAL FOR WOMEN AND CHILDREN IN 2025
Main Article Content
Abstract
Background: Labor induction is increasingly used worldwide and may be performed by mechanical or pharmacological methods. The modified double-balloon Foley catheter is a low-cost mechanical option. Objectives: To evaluate labor induction outcomes using a modified doubleballoon Foley catheter and analyze factors associated with successful induction. Materials and methods: A prospective descriptive interventional study with analytical components was conducted among 182 pregnant women at the Delivery Department of Soc Trang Hospital for Women and Children from May to August 2025. Success was defined as a post-catheter Bishop score ≥ 7 within a maximum catheter retention time of 24 hours; failure was defined as not meeting this criterion or requiring pregnancy termination before assessment because of obstetric indications. Results: The induction success rate was 82.97% (95% CI: 76.73%-87.79%); the vaginal delivery rate was 61.54%. Significant associated factors included pre-induction Bishop score ≥ 3, cervical canal length ≤ 30mm, gestational age of 37-38 6/7 weeks, and neonatal birth weight ≤ 3500g. Conclusion: The modified double-balloon Foley catheter achieved a high cervical ripening success rate and low maternal and neonatal complication rates; findings should be interpreted considering the singlecenter design, convenience sampling, and absence of a control group.
