Background: There is widespread concern about increasing proportion of births by caesarean section. Many factors can affect the likelihood of success of vaginal birth after caesarean section. The purpose of this study was to evaluate the effect of birth weight on the success of labour in women with previous one caesarean section.
Material & Methods: This cross-sectional study was carried out in department of Obstetrics & Gynaecology, Women and Children Hospital, Abbottabad, from March 2012 to March 2013. One hundred women were included who had previous one caesarean section and were now in their pregnancy with single fetus at term. These women were in spontaneous labor and consented to undergo trial of scar. Patients were grouped according to birth weight as Group-1 <3 Kg, Group-2 with 3.1-3.5 Kg and Group-3 with 3.6-0 Kg. Age in years, period of gestation in weeks and birth weight were recorded.
Results: The mean age of patients was 28.9 (range 25 to 40 years). The mean gestation was 38(37 to 41 weeks). Out of 100 parturient, 59 (59%) had birth weight 2.5-3 Kg while 25(25%) had 3.1-3.5 Kg and only 16(16%) had birth weight 3.6-4 Kg. The overall success rate for vaginal delivery after previous caesarean was highest for Group-1, and lowest for Group-3, suggesting a strong correlation of birth weight with success of vaginal birth after caesarean section.
Conclusion: The chances of success of vaginal birth after caesarean section increases with lowering birth weight.
