The term "umbilical cord" or just "umbilical" has also come to be used for other cords with similar functions, such as the hose connecting surface-supplied divers to their surface supply of air and/or heating, or space-suited astronauts to their spacecraft. Engineers sometimes use the term to describe a complex or critical cable connecting a ...
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 resulting in the presence of shunts to move oxygenated blood and ...
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.
The amnion is the innermost layer and, therefore, contacts the amniotic fluid, the fetus and the umbilical cord. [5] The internal pressure of the amniotic fluid causes the amnion to be passively attached to the chorion. [4] The chorion functions to separate the amnion from the maternal decidua and uterus. [4]
Overt umbilical cord prolapse requires rupture of membranes. This is the most common type of cord prolapse. occult umbilical prolapse: descent of the umbilical cord alongside the presenting fetal part, but has not advanced past the presenting fetal part. Occult umbilical prolapse can occur with both intact or ruptured membranes.
The findings suggest deferred clamping of the umbilical cord likely reduced the risk of death in premature babies by a third, compared to immediate clamping.
The baby was found swaddled in a towel inside a basket and breathing weakly with the umbilical cord still attached around 3 a.m. on Tuesday, Jan. 21, News 4 (WOAI) San Antonio reported on Jan 24.
In velamentous cord insertion, the vessels of the umbilical cord are improperly inserted in the chorioamniotic membrane, and hence the vessels traverse between the amnion and the chorion towards the placenta. [1] [11] Without Wharton's jelly protecting the vessels, the exposed vessels are susceptible to compression and rupture. [1] [9]
