Q: Which of the following is a good predictor of postpartum hemorrhage (PPH)? (select one)
A) low fibrinogen
B) hypotension
C) tachycardia
D) low hematocrit
Answer: A
Low blood pressure and tachycardia usually do not manifest in pregnant patients till late and are a poor indicator of ongoing PPH (choice B and C). On the same token, in severe acute hemorrhage, it takes time before hematocrit shows a drop in the laboratory (choice D).
A fibrinogen level below 200 mg/dL is a reliable predictor of severe PPH, where massive blood transfusion or surgical/procedural intervention is required (choice A).
