Several conditions and risk factors can lead to fetal distress or non-reassuring fetal status, [1] including: Low amniotic fluid (oligohydramnios) If there is too little amniotic fluid around the baby in the uterus, the baby can have trouble moving around in the uterus and its growth and temperature can be impacted.
[1] [4] While typically rupture occurs during labor it may occasionally happen earlier in pregnancy. [3] [1] Diagnosis may be suspected based on a rapid drop in the baby's heart rate during labor. [1] [4] Uterine dehiscence is a less severe condition in which there is only incomplete separation of the old scar. [1]
Uterine atony is the failure of the uterus to contract adequately following delivery. Contraction of the uterine muscles during labor compresses the blood vessels and slows flow, which helps prevent hemorrhage and facilitates coagulation.
The vessels are hence normally protected by Wharton's jelly, which prevents rupture during pregnancy and labor. [10] 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 .
Globally it occurs about 8.7 million times and results in 44,000 to 86,000 deaths per year making it the leading cause of death during pregnancy. [ 4 ] [ 2 ] [ 10 ] About 0.4 women per 100,000 deliveries die from PPH in the United Kingdom while about 150 women per 100,000 deliveries die in sub-Saharan Africa . [ 2 ]
