My sister was recently advised that a risk of leaving the cord to pulse is increasing the baby's blood volume to such an extent as to create an increased risk of jaundice that the baby won't be able to handle. is there any research to this effect? it seems to me to be an answer given off the cuff by a doctor not entirely willing to try something 'new'. Wondered if there is some info I'm not coming across.
There has never been any randomised study evaluating the risks of severe jaundice in relation to the time of cord clamping. However, having a personal experience of thousands of births with late cord clamping and cord cutting (after the delivery of the placenta), I can confirm that, on the contrary, the risk of jaundice is dramatically reduced when there is no interference with the physiological processes. The interpretation is that when mother and newborn baby are not distracted at all during the hour following birth (cutting the cord is a distraction), when they don't feel observed, and when they are not guided in a warm place with the lights off, there is a high probability that the baby will be fast at finding the breast. The suction of the nipple plus the early consumption of colostrum stimulate the bowel movements so that the pigments are quickly eliminated instead of being reabsorbed into the bloodstream and making the jaundice more intense.
