As a result of improved anesthetic procedures and surgical techniques, and also increases the rate of previous caesarean section and advanced maternal age, there has been a progressive increase in cesarean delivery rates in recent years all over the world, for this reason, the importance of the timing of elective cesarean delivery for term deliveries has increased. Most obstetricians are generally unaware of the consequences of their actions because they don't manage the care of neonates. Our aim in this study was to evaluate neonatal outcomes according to the weeks of gestation in selected low-risk pregnant women at 37 weeks, 38 weeks and 39 weeks to determine the most proper time for elective cesarean section with the least incidence of respiratory morbidity. The study were conducted on 300 neonates of healthy pregnant women who delivered by Elective cesarean section in Kasr El Aini Hospital and El Monera General Hospital during six months in the period from December 2012 to May 2013. All the mothers were subjected to full detailed history including: age, parity, gravidity, previous abortions, still births, neonatal deaths, excluding any chronic medical disorder or any acute problems. Primary neonatal outcome were recorded in the form of neonatal birth weight, 1minute and 5-minute Apgar score, respiratory distress, adverse respiratory outcomes (respiratory distress syndrome or transient tachypnea of the newborn), neonatal intensive care unit admission, mechanical ventilation and other complication as death.
