What could cause profuse bleeding in a 27-week pregnant woman with a history of placenta previa?

Hello,

Welcome to icliniq.com.

I understand your concern.

According to your description and scan report (attachment are removed to protect the patient's identity), the placenta is low-lying and coverning the os (the opening of the uterus into the cervix), the baby is around 26 weeks old, and the membranes have ruptured. The baby is now hospitalized for emergency treatment. If the placenta is low-lying, it may bleed profusely if it has already bled twice, which is very concerning. If the membranes truely ruptured, there is a risks of infections, chorioamnionitis, stillbirth, extreamly difficult survival of developing baby because baby's lung are to weak to take breath and survive even with neonatal support. If the placenta still coverning the external os and membrane has ruptured, she requires emergency surgery to avoid life-threatening bleeding. Dexamethasone injections for baby's lung maturation can be given, but it depends on how long they can wait for the second dose because this situation is extreamly dangerous and requires immediate intervention. This case requires multidisciplinary discussions, support, intervention, and counseling of patients and attendants regarding all risks of baby survival and infections, the mother's heavy bleeding need for blood transfusion, and hysterectomy in severe conditions.

I hope you could understand severity of condition and need urgent multidisciplinary attention and intervention.

Thank you.
