GENERAL MEASURES · Abruptio placentae is an emergency, but there is usually time to obtain advice yby telephone and arrange safe transportation to the hospital. Panic is p pnot helpful. If the placenta separation is slight, you may be able to return home for g , y ybed rest and close observation after examination. · Hospitalization required (except for mild cases). The mother will be carefully ) ymonitored for symptoms of shock and signs of fetal distress, which include gabnormal heart rates.
