[Management of persistent posterior occipital presentation. 253 extractions by forceps]

A retrospective study of the notes of 253 deliveries was carried out in the two maternity units attached to the University of Rennes between 1980 and 1985. This followed a review of the literature on delivery of babies presenting with a persistent occipito posterior position. Tarnier's forceps were used in each case with full rotation of the presenting part carried out or else delivery in the occipito posterior position. There were five cases of failed forceps. We have not been able to show that there was a significant statistical difference as far as the neonatal state of the babies was, because to the methods of delivery. On the other hand, there was a greater frequency of urinary-vaginal lesions after full rotation. We therefore suggest that a trial of forceps delivery should be carried out in the operating theatre when the optimal obstetrical conditions have been fulfilled, so long as the manoeuvres are carried out technically easily and so long as Caesarean section is resorted to if all the obstetrical conditions are not fulfilled, or if it seems difficult to deliver the baby with a forceps.
