Under normal circumstances, the placenta to the uterine wall far from the uterine opening or else migrates out of the way as the pregnancy progresses. In certain cases, the placenta may partially or completely cover the cervix. This is called a placenta previa. it can cause hemorrhagic bleeding, HIE, and birth trauma.
Types of Placenta Previa
Further, some women have what is named a low-lying placenta, which is when the placenta is very near to, but not hindering, the cervical opening. This often transfers upward in the uterus throughout pregnancy without medical interference.
|Multiparity||Prior Uterine surgery|
|Cocaine use||Advancing age(> 35 years)|
|Erythroblastosis||Low socioeconomic status|
|Non-white Ethnicity||Short interpregnancy interval|
|Infertility treatment||Multiple gestation (large surface area of placenta)|
The reason of placenta previa are unidentified. But 1 in 500 woman suffer from placenta previa is more common in woman who have had more than one child, a caesarean birth, surgeries on the uterus and or triplets or twins.
Naturally, the initial sign of placenta previa is bleeding during the second half of pregnancy. The bleeding can differ from nominal to plentiful.
Several women with placenta previa will stop bleeding and then start again. Contractions may or may not be present. An ultrasound needs to check the diagnosis of placenta previa.
If the baby is < 37 weeks gestation or preterm and bleeding is not found/has subsided, then instant delivery is pointless, and the Pregnant lady may be treated on an outpatient basis. Doctor should sensibly monitor mother with placenta previa and offer emergency care if their bleeding becomes more tenacious. If the baby is > 37 weeks gestation or mature and the mother is in labor pains, or if haemorrhaging is present, instant delivery of the fetus via C-section is essential to stop hypoxic-ischemic encephalopathy and other injuries.
Treatment for placenta previa depends on severity. Bed rest is most important. sexual abstinence. a C-Section or blood transfusion maybe needed in critical cases.
