Objective: Compare the effectiveness and safety of the ECV when the procedure is performed by senior experienced obstetricians or by super-specialized professionals who composed a dedicated team. Design: Longitudinal prospective analysis. Setting: 1st of January of 2018 and 31st of December of 2019. Population: Pregnant women with non-cephalic presentation and no contraindication for vaginal delivery. Methods: Longitudinal prospective analysis of ECV performed in a tertiary hospital. From 1/1st/2018 to 10/1st/2019, ECV were performed by two senior experienced obstetricians who composed the dedicated team for ECV, designed as Group A. From 10/1st/2019 to 12/31st/2019, ECV was performed by two seniors obstetricians, designed as Group B. Ritodrine was administered during 30 minutes just before the procedure. Propofol was used for sedation. Main Outcome Measures: ECV success rate, ECV complication rate, cesarean section 24 h after ECV. Results: 186 pregnant women were recruited (150 patients in group A and 36 patients in group B). ECV success rate increased from 47.2% (31.7-63.2) in Group B to 74.0% (66.6-80.5) in Group A. The greatest increase in the success rate of ECV was seen in nulliparae, from 38.5% (21.8-57.6) in group B to 69.1% (59.4-77.6). Complications rate decreased from 22.2% (11.1-37.6) in Group B to 9.3% (5.5-14.8) in Group A. Conclusions: The introduction of an experienced dedicated team improves ECV success rate, especially in primiparas, and it also reduces ECV complications rate.
