The Umbilical cord stump, left behind after omphalotomy. Omphalotomy is the medical procedure that involves the cutting of the umbilical cord after childbirth. [1] The word omphalotomy is derived from the prefix omphal(o)-, from the Ancient Greek word ὀμφαλός (omphalós), meaning navel, and the suffix-tomy, also from Ancient Greek, meaning incision.
Often a deterioration of the fetal heart rate is a leading sign, but the cardinal sign of uterine rupture is loss of fetal station on manual vaginal exam. Intra-abdominal bleeding can lead to hypovolemic shock and death. Although the associated maternal mortality is now less than one percent, the fetal mortality rate is between two and six ...
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.
A Cochrane review suggests that active management (use of uterotonic drugs, cord clamping and controlled cord traction) during the third stage of labour may reduce severe bleeding and anemia. [51] However, the review also found that active management increased the patient's blood pressure, nausea, vomiting, and pain.
The embryo is surrounded by the thin membranes of the amniotic sac, the umbilical cord is seen in the center, attaching the embryo to the placenta. The umbilical cord develops from and contains remnants of the yolk sac and allantois. It forms by the fifth week of development, replacing the yolk sac as the source of nutrients for the embryo. [2]
Reasons for the operation include, but are not limited to, obstructed labor, twin pregnancy, high blood pressure in the mother, breech birth, shoulder presentation, and problems with the placenta or umbilical cord. [2] [3] A caesarean delivery may be performed based upon the shape of the mother's pelvis or history of a previous C-section.
The ear is built to function like a "conveyor belt" by sloughing off dead skin and earwax that naturally pushes its way out. This system tends to work well without much need for assistance.
Umbilical cord prolapse is when the umbilical cord comes out of the uterus with or before the presenting part of the baby. [2] The concern with cord prolapse is that pressure on the cord from the baby will compromise blood flow to the baby. [2] It usually occurs during labor but can occur anytime after the rupture of membranes. [1] [5]
