Cord clamping is delayed by 1-3 minutes in neonates because?

Appeared in: Chitranjjan National Cancer Institute Kolkata - 2021

Explanation

Delayed cord clamping allows for placental transfusion, where a significant amount of blood (80-100 mL) transfers from the placenta to the newborn.
This process increases the neonate's blood volume and, most importantly, boosts their iron stores.
Higher iron stores help prevent iron-deficiency anemia in the infant for the first several months of life.
For preterm infants, DCC also reduces the risk of intraventricular hemorrhage and necrotizing enterocolitis.

Option A: Delayed cord clamping does not impact the mother's hemoglobin status or risk of postpartum hemorrhage.
Option B: Placental separation is a physiological process driven by uterine contractions after the baby is born, not by the timing of cord clamping.
Option C: Delayed cord clamping can slightly increase the risk of hyperbilirubinemia (jaundice) because of the higher red blood cell volume that needs to be broken down. The benefits of DCC, however, generally outweigh this manageable risk.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Benefits of Delayed Cord Clamping (DCC) as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in advocating for and implementing delayed cord clamping in eligible newborns, ensuring the baby is kept warm and stable during the process.
Patient education is key. Nurses should inform parents about the benefits of DCC and also about the slightly increased risk of jaundice, explaining the signs to watch for and the availability of phototherapy if needed.
What if? If a newborn requires immediate resuscitation due to distress (e.g., poor tone, inadequate breathing), immediate cord clamping is necessary to move the baby to the resuscitation area without delay. In such cases, the need for immediate medical intervention outweighs the benefits of DCC.

How to Approach the Question

Identify the core concept: The question asks for the reason ('because') behind the practice of delayed cord clamping.
This is a factual recall question based on obstetric and neonatal best practices.
Evaluate each option based on physiological principles.
Option A (maternal anemia): Consider the direction of blood flow. Blood flows from placenta to baby, so it wouldn't benefit the mother.
Option B (placental separation): Recall that uterine contractions, not cord status, cause the placenta to detach.
Option C (jaundice): Think about bilirubin metabolism. More blood means more red cells to break down, which would increase, not prevent, bilirubin levels.
