Demarcation Ring

Ring of Demarcation: Sign of Live Birth

The ring of demarcation, also known as the umbilical cord scar, is a red line that appears at the base of a newborn's umbilical cord towards the end of the first 24 hours of life. This physiological sign is one of the indicators confirming that the child was born alive.

Immediately after birth, the umbilical cord connects the fetus to the mother, providing essential nutrition and oxygen. However, as time passes after birth, the umbilical cord ceases to be functional and begins to gradually dry out. This process causes changes in the umbilical cord itself and leads to the formation of a demarcation ring.

The demarcation ring occurs due to contraction of the vessels that previously provided blood supply to the umbilical cord. The contraction of these vessels results in restricted blood flow and ultimately the formation of a bright red line at the base of the umbilical cord. This usually occurs between 12 and 72 hours after the baby is born.

The presence of a demarcation ring is an important sign of live birth. Doctors and medical staff can use it as one of the indicators to determine whether a baby was born alive or stillborn. In combination with other clinical and physiological signs, the ring of demarcation helps medical professionals make appropriate conclusions about the health of the newborn.

It is important to note that the presence of a demarcation ring is not the only indicator of live birth. Doctors also look at other signs such as breathing, heart rate, movement and response to stimuli. The combination of these signs allows us to determine how healthy the child is and how adapted to life outside the womb.

In conclusion, the ring of demarcation is a red line that appears at the base of a newborn's umbilical cord during the first 24 hours of life. This sign is one of the indicators that helps determine that the child was born alive. When combined with other clinical signs, the ring of demarcation helps health care professionals assess the overall health of the newborn and guide appropriate care.

The ring of demarcation is a red line that appears towards the end of the first days of a newborn’s life and is located at the base of the umbilical cord. The presence of a demarcation ring is one of the important signs of live birth and indicates that the child was born naturally.

In the first days of a child's life, the umbilical cord has not yet completely fallen off, and its remains form a demarcation ring that gradually disappears over time. This occurs due to the fact that the remnants of the umbilical cord begin to decompose under the action of enzymes secreted by the child’s body.

In addition, a ring of demarcation may be a sign of certain diseases, such as intrauterine infection or fetal growth restriction. Therefore, it is important to monitor the condition of the newborn and if any deviations from the norm appear, consult a doctor.

However, there is no need to worry about the presence of a demarcation ring in a newborn. This is normal and should not cause concern. The main thing is that the child is healthy and develops normally.
