The Optimum Time for Cord Clamping after Vaginal Delivery in Term Pregnancy

Abstract

Given the benefits for most newborns and in conjunction with other professional organizations, the American College of Obstetricians and Gynecologists now recommends delaying umbilical cord clamping in newborns born after a full gestation period and premature infants for at least 30-60 seconds after birth. Late umbilical cord clamping appears to be a useful procedure for premature babies. For newborns born after a full pregnancy, delayed cord clamping helps to increase hemoglobin levels at birth and improves iron stores in the first months of life, which may have a positive effect on growth. Before 1950, the term early clamping was called umbilical cord clamping within one minute of birth, and the later clamp was known as umbilical cord clamping more than 5 minutes after birth. After several small studies of postpartum blood volume change, it was reported that 80-100 ml of blood passed from the placenta to the newborn baby in the first 3 minutes after birth; 90% of the blood volume was transferred during the first breaths of healthy embryos. Some randomized case studies based on a control group of postnatal and premature infants; physiological studies of blood volume, oxygenation and arterial pressure have had positive effects for immediate cat versus delayed umbilical cord picking. It should be noted that late umbilical cord clamping for premature newborns.
