My sister has a dead baby in her womb.

Hello Ma'am. The blood pressure is very high and the Dead baby in the uterus is a life threatening siituation and require immediate medical intervention. Have you asked them that what has been done for the elevated blood pressure and what should be done to evacuate the baby. Ma'am,  the Dead baby can be evacuated without surgery & the. Blood pressure comes to normal after the procedure. I advice you to ask the concerned doctor for the delay. At this high blood pressure,  any intervention is risky. First of all, the task is to bring down the blood pressure gradually not abrubtly,  and I think due to uncontrolled blood pressure, May be there is a delay. Kindly don't worry and get dishearted.  It happened to me also but everything went Very well. Have your faith in God and doctors. Regards. Bye.
