E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Demonstrate that with concomitant and synchronous use of supracervical balloon and vaginal misoprostol for induction of labour, vaginal delivery is achieved in less time compared with vaginal misoprostol alone. |

|
E.2.2 | Secondary objectives of the trial |

1- Evaluar la capacidad de maduración cervical y progresión al trabajo de parto. 2- Evaluar la necesidad y dosis de fármacos para la maduración y estimulación del parto. 3- Evaluar la necesidad de analgesia para el parto. 4- Evaluar los efectos adversos durante el trabajo de parto y resultados perinatales. 5- Evaluar la vía y tipo de parto. |

E.4 | Principal exclusion criteria |
1- Exclusion criteria pre-randomization: - Patient refusal to participate in the trial - Misoprostol contraindication acording to the misoprostol leaflet: - Severe Preeclampsia - Prematurity (<37 weeks gestation dated by first trimester ultrasound) - Previous cesarean section or previous uterine surgery - Intrauterine growth restriction - Whenever placement of supracervical balloon might lead to an increase in the risk of infections and chorioamnionitis: - Premature rupture of membranes - Maternal colonization with Streptococcus agalactiae at any time during the pregnancy - Other infrequent situations that may act as a confounder factor: - Multifetal gestation - Breech presentation - Stillbirth
2- Exclusion criteria postrandomization - Maternal leaving of the study during induction - Adverse effects secondary to the supracervical balloon, such as pain or maternal discomfort |
1- Criterios de exclusión prealeatorización - Negativa de la paciente a participar en el ensayo - Las indicaciones que no contempla el prospecto del misoprostol para la inducción del parto: - Preeclampsia grave - Prematuridad (< 37 semanas de gestación datada por ecografía durante el primer trimestre de embarazo) - Cesárea o cirugía uterina corporal previa. - Retraso de crecimiento intrauterino - Siempre que se considere que la colocación de un balón supracervical pueda condicionar un aumento en la tasa de infecciones y corioamnionitis: - Inducciones por rotura prematura de membranas - Colonización materna por Streptococcus agalactiae detectada por cultivo positivo en cualquier momento del embarazo o durante las 5 semanas previas a la inducción - Otras situaciones que por su pequeño volumen no representan resultados significativos y pueden actuar como factor de confusión: - Gestación múltiple - Presentación de nalgas - Óbito fetal
2- Criterios de exclusión postaleatorización - Abandono del estudio durante la inducción - Aparición de reacciones adversas al balón supracervical, tales como dolor o disconfort. |
