This study attempted to determine whether delivery with Kielland's forceps for deep transverse arrest is less favourable than other instruments. One hundred and forty-six women who underwent rotation and delivery with Kielland's forceps between 1994 and 1997 were matched by parity and birth weight to one of two control groups: delivery by non-rotational forceps or the vacuum extractor. No significant differences were found in maternal or neonatal outcome (vaginal lacerations, 3rd- or 4th-degree perineal tears, postpartum haemorrhage, fever, blood transfusion, duration of hospitalisation, Apgar score, asphyxia, scalp trauma, admission to the intensive care unit or neonatal hospitalisation). The incidence of heart rate abnormalities prior to instrumental delivery was similar. The 'failure to deliver' rate (8.9% after Kielland's forceps) was not different to the 7.5% and 6.8% found in each control group. These data indicate that the outcome after Kielland's forceps delivery is similar to other instrumental deliveries if performed by experienced obstetricians.
