Résumé (français)  :

Abstract (English)  :

Women were randomly allocated by the opening of a sealed envelope before the onset of second stage of labour.

636 women were randomised. 97 were excluded from analyses. London, England.
226 study participants: 111 primigravidae, 115 multigravidae.
313 control subjects: 140 primigravidae, 173 multigravidae.
All women had full term (37 weeks completed) gestation.
Singleton pregnancies.
Induced and spontaneous labours were included.
Women who had epidural anesthesia were included.

Study group: 318 women were randomly allocated to deliver in a ’Birth E-Z’ chair. The delivery was conducted with the chair tilted back to an angle of 40 degrees. 92 women in the study group were excluded from the analyses as they did not deliver in the chair.

Control group: 318 women were randomly allocated to deliver on the bed in the dorsal position, but were allowed to be propped up with a pillow. 5 women were excluded from the analyses as they insisted on delivering in the chair.

Unfortunately the authors excluded 92 women who were randomly allocated to use the chair, but delivered in the bed, from the analyses. Five women were excluded from the control group who insisted on using the chair for delivery. These exclusions could have affected the results and the data must be interpreted with care.
’Perineal tears’ were included in review as second degree tears. It is not clear in the article if these include first degree tears.
