Determinar la eficacia de la versión externa previa tocólisis con terbutalina en disminuir las presentaciones de nalgas en el momento del parto.
Material y métodosEstudio prospectivo observacional en gestaciones únicas a término no complicadas, diagnosticadas de presentación de nalgas. No se excluyen cesáreas previas. Tocólisis con terbutalina.
ResultadosRealizamos 43 intentos de versión externa, con un porcentaje de éxito del 55,8% de los casos. Observamos un aumento de la eficacia si se realiza antes de la semana 38 (80%) que a partir de ésta (42,9%), con unas diferencias estadísticamente significativas (p < 0,05). No se encuentran diferencias estadísticamente significativas en el porcentaje de éxito valorando la variedad de nalgas o paridad. No se han observado complicaciones en los 43 intentos.
ConclusionesLa versión externa es un método válido y con baja incidencia de complicaciones para disminuir las presentaciones de nalgas en el momento del parto.
To evaluate the efficacy of the external cephalic version in decreasing the frequency of breech presentations at delivery.
Material and methodsWe performed a prospective, observational study in subjects with a single breech fetus at term without clinical complications. External cephalic version attempts were performed with previous tocolysis with terbutaline. Patients who had previously undergone cesarean section were not excluded.
ResultsForty-three external cephalic version attempts were made, of which 55.8% were successful. There was a statistically significant (p < 0.05) increase in the effectiveness of external cephalic version attempts made before 38 weeks' gestation (80%) compared with attempts made at ≥ 38 weeks (42.9%). No statistically significant differences in the success rate were found between groups in parity or type of breech. No complications were observed in the 43 attempts.
ConclusionsExternal cephalic version is effective in reducing the number of breech presentations at delivery and has a low complication rate.
