To evaluate the silastic cupped obstetric vacuum extractor, a retrospective study was made of 100 women in whom vacuum extraction was attempted, comparing them to 50 women in whom rotational forceps delivery was attempted. The vacuum extractor far more frequently failed to achieve delivery alone compared to the forceps (54% cf 4% respectively). However, in most failure cases (94%) descent and/or rotation of the fetal head occurred allowing a liftout forceps delivery. Apart from episiotomy, maternal trauma was not a problem with vacuum extraction. There were two neonatal deaths in the study groups, one following delivery by caesarean section for failed vacuum extraction and failed forceps and one following vacuum extraction of a markedly pre‐term infant. Neonatal morbidity was otherwise minor but was more common in the vacuum extraction group, consisting mainly of ex‐tracranial haematomata and jaundice.
