Background: Caesarean section can be performed before labour, during first and second stages of labour. Present study was aimed to compare fetomaternal outcome in women undergoing caesarean section in first stage vs second stage of labour at a tertiary hospital. Material and Methods: Present study was prospective, comparative study, conducted in pregnant women, between 21-35 years of age, Singleton, term pregnancies, low risk & fit for vaginal delivery underwent emergency LSCS. Pregnant women were divided into 2 groups as group 1 (LSCS in the first stage of labour) & group 2 (LSCS in the second stage of labour). Results: Maternal complications such as blood transfusions (4 % vs 7 %), bladder high up (1 % vs 10 %), hematuria (2 % vs 17 %), unintended extensions (2 % vs 14 %), wound dehiscence (3 % vs 11 %) & febrile morbidity (4 % vs 16 %) were more among women underwent LSCS in second stage of labour, difference was statistically significant. Neonatal morbidities such as Apgar Score <7 at 5 min (2 % vs 6 %), Neonatal septicaemia (2 % vs 10 %), Intubation not for meconium (1 % vs 7 %), NICU stay >24 hrs (2 % vs 19 %) were more in women underwent LSCS in second stage of labour, difference was statistically significant. Fetal injuries (2 %) were noted only in women who underwent LSCS in second stage of labour. Conclusion: Maternal complications (blood transfusions, hematuria, unintended extensions, wound dehiscence & febrile morbidity) & neonatal morbidities (Apgar Score <7 at 5 min, Neonatal septicaemia, Intubation not for meconium & NICU stay >24 hrs) were more in women underwent LSCS in second stage of labou
