Résumé (français)  :

Objectif : déterminer si il y a moins d’extractions instrumentales lorsque le second stade du travail se déroule sur une chaise d’accouchement [obstetrical birth chair] que lorsqu’on utilise la position allongée classique, pour des nullipares.

Essai clinique randomisé utilisant des enveloppe cachetées pour l’affectation des groupes.

Lieu : grand hôpital universitaire [teaching hospital]

Patientes : 1250 nullipares, singletons, foetus vivant en position céphalique, sans anesthésie péridurale, arrivant à dilatation totale.

Intervention : les interventions consistent à mener second et troisième stade du travail soit dans des sièges d’accouchement EZ (birth-EZ chair), soit sur lit classique d’accouchement, en fonction de la randomisation.

Mesure primaire : extractions instrumentales. Mesures secondaires : durée du second stade du travail, traumatismes périnéaux, pertes de sang, avis des femmes, état néonatal.

Résultats : pas de réduction générale des extractions instrumentales lorsque la naissance à lieu sur des sièges. Cependant il y a réduction des extractions instrumentales pour anomalie du rythme cardique foetal. Il n’y a pas d’amélioration pour les traumatismes périnéaux ou les douleurs périnéales puerpérales. Les hémorragies post-partum sont plus fréquentes dans le groupe des sièges d’accouchement.

Abstract (English)  :

OBJECTIVE--To determine whether nulliparae whose second stage of labour is conducted in an obstetric birth chair have a lower incidence of instrumental delivery than those using a conventional delivery bed.

DESIGN--Randomized controlled trial using sealed, opaque envelopes for allocation.

SETTING--Delivery ward in a busy teaching hospital.

PATIENTS--1250 nulliparae with a singleton live fetus with cephalic presentation, without epidural anaesthesia, who had achieved full dilatation.

INTERVENTION--Intention to conduct second and third stages of labour in either the Birth-EZ chair or the conventional delivery bed, as randomly allocated.

MAIN OUTCOME MEASURES--Primary measure: vaginal operative delivery; principal secondary measures: duration of second stage, perineal trauma, blood loss, women’s views, and neonatal status.

RESULTS--Delivery in the birth chair did not result in a reduction in operative delivery, overall. However, there was a reduction in vaginal operative delivery for fetal heart rate abnormality. There was no beneficial effect on perineal trauma or puerperal perineal pain. Post-partum haemorrhage was more frequent in the birth chair group.

CONCLUSIONS--Delivery in the birth chair does not offer any obvious advantage to women over delivery on a bed.
