Background: Pregnancy and delivery are considered as normal in women. Some of the deliveries put the mother and baby's life at risk requiring caesarean section but sometimes it is also performed on request. Negative obstetric and perinatal outcomes are more likely after a cesarean section.  Objectives: Our research was done to demonstrate how operating time affects the immediate neonatal outcome.   Methodology: The study included 200 women having a singleton pregnancy, a full term cesarean delivery, and no underlying medical conditions (uncomplicated pregnancy), fetal distress or neonatal congenital anomalies. The neonates were assessed and evaluated through Apgar score.   Results: the duration from incision of the skin till clamping the cord was ranged between 3 and 22 minutes, and the duration from incision of the uterus till clamping of the cord was ranged between .5 to 4 minutes. No significant correlation between Apgar score of the neonates, either after 1 minute or 5 minutes, and the U-C interval. 13 neonates developed Transient Tachypnea of Newborn (TTN) and transferred to NICU. Gestational age ranged between 38 and 40 weeks, with mean of 38.740± 0.753 weeks. TTN was developed in 7 males and 6 females. no significant relation between BMI and development of TTN. no significant correlation between the S-C interval and the development of TTN. No statically significant correlation between development of TTN and U-C interval. Conclusion: Gestational Age is a predictor for the development of TTN; CS is preferred to be done at 39 weeks. Increase the duration from the uterine incision till the cord clamp increase the probability of TTN occurrence.
