Abstract
The pattern of cervical dilatation during labour in 100 patients with previous lower segment caesarean section (LSCS) was determined in a prospective partographic study. Eighty-four subjects delivered successfully by vaginal route. The mean initial dilatation rate (IDR) and average dilatation rate (ADR) were 0.884 cm/hour and 1.255 cm/hour respectively. The mean IDR and ADR of the patients who delivered vaginally were 0.96 cm/hour and 1.41 cm/hour respectively, while of those who required repeat LSCS mean IDR was 0.44 cm/hour and mean ADR was 0.42 cm/hour. Hence ADR in cases who required repeat LSCS was significantly slower as compared to those who delivered vaginally (p < 0.01). Most (87.5%) of the cases who required repeat LSCS crossed the alert line as compared to 34.5% of patients who delivered vaginally. The mean admission delivery interval (ADI) was 9.45 +/- 4.29 hours in patients with no previous vaginal delivery and 8.02 +/- 4.83 hours in patients with previous vaginal delivery. The mean durations of 1st and 2nd stages of labour were 11.8 +/- 5.35 hours and 29.4 +/- 27.3 minutes respectively. It is concluded that partographic evaluation is an important aspect in management of labour of such patients.
