About Cord Clamping and Placental Transfusion

Reputable Cord Clamping Information

At Information About Umbilical Cord Clamping, we understand that finding reliable medical information can be challenging. With this in mind, we've created an easy-to-use information guide that explains the importance of a placental transfusion via delayed cord clamping or cord milking at birth. For additional insights, be sure to check out our detailed list of cord clamping research publications.

Umbilical Cord Blood (Placental Transfusion) and Cord Clamping 

During pregnancy, the placenta acts as the baby's lungs, providing oxygen to enrich the baby's blood. Cutting the umbilical cord immediately after birth leaves most of this blood in the placenta, depriving your baby of a vital resource for continued health. However, waiting several minutes to clamp and cut the cord allows the blood to flow back into your baby's body. This makes your baby warmer, lessens the likelihood or anemia, promotes brain function, and even increases infant survival rates.

Many new studies have found cord blood to be incredibly valuable to infant health. This blood is very precious and has remarkable benefits for continued infant development. Our goal is to empower parents to seek out delayed cord clamping in order to preserve their baby's own blood in the baby's body as nature intended. We encourage families to find a provider who also believes in delayed cord clamping.

About Dr. Mercer

Dr. Judith Mercer obtained her midwifery education at Columbia University graduating in 1974 and a doctorate from The Catholic University of America in 1989. She practiced midwifery in all settings throughout her career while focusing on midwifery education and serving as program director at Georgetown from 1980 to 1990. Later moving into research, she has been funded by NIH three times for her work on the effects of delayed cord clamping for preterm and term infants and has presented her research worldwide. In 2014, she received the highest award (Hattie Hempschmeyer) from the American College of Nurse-Midwives. Currently, she is Professor Emerita at the University of Rhode Island, Research Scientist at Women & Infants Hospital, and Adjunct Professor of Pediatrics at Alpert School of Medicine, Brown University and Principal Investigator with Dr. Debra Erickson-Owens and Dr. Sean Deoni for “Effects of Placental Transfusion on Early Brain Development in Term Infants.” An early experience in her career of resuscitating an infant with cord still intact started her on her research path. Today, she shares her decades of research and experience with parents in hopes of providing the best possible beginning to life for generations of infants.
