False
What imaging technique is commonly used to diagnose placenta abruptio?
Ultrasound
Types Placenta abruptio is classified into
Revealed : bleeding is revealed through the vagina
Concealed : no visible blood in the vagina. But there is internal bleeding
Mixed : both
What is the typical management for mild cases of placenta abruptio?
Monitoring and bed rest
What is the role of tocolytics in treating placenta abruptio?
Tocolytics are used to relax the uterus and reduce contractions.
What is a possible consequence of untreated severe placenta abruptio?
Maternal shock or death
What is the term for the area where the placenta detaches from the uterus in cases of abruptio?
Retroplacental hemorrhage
What is the preferred mode of delivery in cases of severe placenta abruptio?
Cesarean section
Active management of placenta abruptio
Analgesic such as pethidine 100 mg is given and blood is taken for necessary investigations. Blood is also cross-matched immediately and at least 6 units should be requested. In the meantime an intravenous infusion of plasma could be commenced if bloodisnotimmediatelyavailable.

Heamorrhage
oxytocic infusion containing 20 units of syntocinon in 500 ml 5% dextrose.
Coagulation defects
Forearlydetectionof coagulation defects, clotting time should be done every 2-4 hours. Ifthe patient continues to bleed afterdeliveryandtheclottingtimeismorethan10 minutes, coagulation defect is invariably the cause. Fibrinolysin test and platelet count should also be performed. The bedside clotting time
observation is done by placing 2ml of blood in a drytesttubeandregularlyinvertthetubebetween the finger and thumb. The fibrinogen level will in coagulation defect fall below 100-150mg/100 ml (normal level in pregnancy is between 300- 700mg/lOOml).Ifhypo-orafibrinogenaemia is confirmed from the above tests which include clotting time, fresh blood or pure
