The cord can be clamped at different times; however, delaying the clamping of the umbilical cord until at least one minute after birth improves outcomes as long as there is the ability to treat the small risk of jaundice if it occurs. [18] Clamping is followed by cutting of the cord, which is painless due to the absence of nerves.
The umbilical arteries are actually the anterior division of the internal iliac arteries, and retain part of this function after birth. [3] The umbilical arteries are one of two arteries in the human body, that carry deoxygenated blood, the other being the pulmonary arteries. The pressure inside the umbilical artery is approximately 50 mmHg. [4]
Controlled cord traction (CCT) consists of pulling on the umbilical cord while applying counter pressure to help deliver the placenta. [5] It may be uncomfortable for the mother. Its performance requires specific training. Premature cord traction can pull the placenta before it has naturally detached from the uterine wall, resulting in hemorrhage.
In a subgroup of premature babies born before 32 weeks of pregnancy, 44.9% (449/1001) with immediate cord clamping experienced hypothermia after birth, compared to 51.2% (509/994) of those with ...
In humans, the circulatory system is different before and after birth. The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels. A major difference between the fetal circulation and postnatal circulation is that the lungs are not used during the fetal stage ...
Casey Merrell, 32, began creating artwork from umbilical cords after the birth of her first son. "I wasn't certified or trained yet — I had barely even heard of it," Merrell says of creating ...
The medial umbilical ligament, cord of umbilical artery, or obliterated umbilical artery is a paired structure found in human anatomy. It is on the deep surface of the anterior abdominal wall , and is covered by the medial umbilical folds ( plicae umbilicales mediales ).
Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the often protruding scar left by the detachment of the umbilical cord. This is located in the center of the navel, sometimes described as the belly button. Around the cord remnant is the "umbilical collar", formed by the dense fibrous umbilical ring ...
