title: Outcome of the second labour in patients whose first labour was prolonged: the Dublin experience.
abstract: This observational study examined the outcome of the second delivery in patients whose first labour was prolonged. The onset of labour was defined as that time when the diagnosis of labour was made on admission to the delivery unit. The first labour was defined as prolonged when delivery occurred more than 12 h later. The study was confined to those patients (n = 66) who had a prolonged first labour with a single, live fetus and cephalic presentation during 1984-1987 and who had a subsequent labour. Sixty-one of the 66 patients (92%) delivered vaginally, and 5 were delivered by emergency caesarean section. Forty-six (70%) delivered within 6 h of admission. Although all 66 had received oxytocin in their first labour, only 8 (12%) required oxytocin in their second labour. Fourteen (82.4%) of the 17 patients with a previous caesarean section had a vaginal delivery. These results indicate that compared to the first labour the duration of the second labour and the oxytocin requirements in the second labour were significantly reduced. These findings are reassuring for patients who have had a long difficult first labour.
