Risk factors for postpartum hemorrhage following cesarean delivery.

Objective: To identify risk factors for postpartum hemorrhage (PPH) following cesarean delivery (CD).

Methods: A retrospective study of all women who underwent CD in a university-affiliated tertiary hospital (2014-15). PPH was defined as any of the following: clinical PPH (≥1000 ml estimated blood loss), hemoglobin (Hb) drop ≥3 g/dl (the difference between pre-CD Hb level within a 24 h prior to the delivery) and post-CD (nadir level during the first 72 h after CD)) or the need for blood products transfusion.

Risk factors for post-partum hemorrhage following vacuum assisted vaginal delivery.

Objective: To identify risk factors for post-partum hemorrhage (PPH) following vacuum assisted vaginal delivery (VAVD).

Study Design: A retrospective study of all women with singleton pregnancies who underwent VAVD in a tertiary hospital (2012-2014). PPH was defined as any of the following: ≥500 ml estimated blood loss, hemoglobin drop ≥3 g/dl (difference between pre- and post-VAVD hemoglobin levels) or the need for blood products transfusion.
