Erratum: External Cephalic Version: Is it an Effective and Safe Procedure?

External cephalic version (ECV) is a procedure for modifying the fetal position and achieving a cephalic presentation. The objective of the ECV is to offer an opportunity for cephalic delivery to occur, which is widely known to be safer than breech or cesarean section. ECV is usually performed before the active labor period begins. Factors associated with a higher ECV success rate include1,4: multiparity, a transverse presentation, black race, posterior placenta, amniotic fluid index higher than 10 cm.
However, ECV is not an innocuous procedure and may present7,11 intraversion complications such as premature rupture of membranes, vaginal bleeding, transitory changes of fetal heart rate, cord prolapse, abruptio placentae, even stillbirth.
In this article, we analyzed ECVs performed under analgesia and tocolysis. To date, no video report has been published showing how to perform this procedure with analgesia and tocolysis. The main objective of this study is to show how ECV is performed. We also describe some key actions that could improve the procedural success. As a secondary objective, we analyzed the results of ECV obtained following the specific protocol with tocolysis and analgesia and compared the results with the literature. We also analyzed factors associated with ECV success rate, type of delivery and a comparison of the type of delivery in ECV pregnant women with non-ECV pregnant women were also included.

external cephalic version: is it an effective and safe procedure?

External cephalic version (ECV) is an effective procedure for reducing the number of cesarean sections. To date, there is no video publication showing the methodology of this procedure. The main objective is to show how to perform ECV with a specific protocol with tocolysis before the procedure and analgesia. Moreover, we describe and analyze the factors associated with successful ECV, and also compare to deliveries in the general pregnant population.
A retrospective and descriptive analysis of ECV carried out at the Hospital Clinico Universitario Virgen de la Arrixaca in Murcia (Spain) between 1/1/2014 and 12/31/2018 was assessed. The latest data available of labor deliveries in the local center, which is the biggest maternity department in Spain, were from 2018.
320 patients were recruited and 3 pregnant women were lost during the study. ECV was carried out at 37&#177;3 weeks gestation. ECV was successful in 82.5% (N=264). 19 complications were reported (5.9%): 8 vaginal bleeding (2.5%), 9 fetal bradycardia (2.8%), 1 preterm rupture of membranes (0.3%) and 1 cord prolapse (0.3%). A previous vaginal delivery increases the success rate of ECV ORadjusted=3.03 (1.62-5.68). Maternal Body Mass Index (BMI) affects the success of ECV ORadjusted=0.94 (0.89-0.99). Patients with BMI&#62;40 kg/m2 have an ORadjusted=0.09 (0.009-0.89) compared with those with BMI &#60;25 kg/m2. If ECV was successful, the cesarean delivery index is 22.2% (17.5-27.6%), the eutocic delivery index is 52.1% (46.1-58.1%) and the instrumented vaginal delivery index is 25.7% (20.7-31.2%). There are no differences in cesarean and eutocic delivery indexes after successful ECV. However, a successful ECV is associated with a 6.29% increase in the instrumented delivery rate (OR=1.63).
ECV is an effective procedure to reduce the number of cesarean sections for breech presentations. Maternal BMI and previous vaginal delivery are associated with ECV success. Successful ECV does not modify the usual delivery pattern.

Three hundred and twenty patients were recruited between January 1, 2014 and December 31, 2018. Three patients were lost during the follow-up after the ECV because delivery was not carried out in our hospital.
Statistics were derived from the raw data. To study the differences between groups, unpaired Student&#39;s t-tests were used for quantitative variables and chi-square tests for dichotomous variables. All tests were two-tailed at a 0.05 significance level.
