Résumé (français)  :

Nouvelle chaise obstétricale conçue pour résoudre certains problèmes de celles actuellement commercialisées. La chaise a été utilisée pour évaluer les effets sur les résultats de l’accouchement lorsque le second stade du travail se fait en position assise. 304 femmes sont assignées au hasard à accoucher sur la chaise ou en position couchée sur le dos. L’accouchement avec la chaise n’a pas eu d’effets bénéfiques sur les mères ni sur les bébés et a eu pour conséquence une perte de sang moyenne plus élevée ainsi qu’un plus haut taux d’hémorragie.

Abstract (English)  :

A new obstetric chair has been designed to overcome some of the problems of those currently available commercially. The chair has been used to assess the effects of the sitting position in the second stage of labour on the outcome of delivery in 304 women randomly allocated to be delivered either in the chair or in the conventional dorsal position. Delivery in the chair conferred no benefits to mother or baby and resulted in greater mean blood loss and a higher rate of postpartum haemorrhage.

Argument (français) :

Etude randomisée contrôlée comparant l’accouchement avec une chaise obstétricale à la position lithotomique (incluant le décubitus latéral). Aucun avantage n’est trouvé à l’utilisation de cette chaise avec laquelle on observe plus d’écoulements sanguins et d’hémorragies post-partum.

Argument (English):

Randomized controlled trial comparing delivery with an obstetric chair at the lithotomic position (including lateral decubitus). No advantage is found in the use of this chair with which there is more blood flow and postpartum haemorrhage.

Argumento (português):

Estudo controlado randomizado comparando o parto com uma cadeira obstétrica na posição litotômica (incluindo decúbito lateral). Nenhuma vantagem é encontrada no uso desta cadeira com a qual há mais fluxo sanguíneo e hemorragia pós-parto.
