Predictive Performance of Shock Index for Postpartum Hemorrhage During Cesarean Delivery

( Int J Obstet Anesth . 58;2024:103957. https://doi.org/10.1016/j.ijoa.2023.103957) Postpartum hemorrhage (PPH) is a significant obstetric emergency that accounts for ∼20% of maternal deaths globally. In cesarean deliveries (CD), PPH is often described as blood loss >1000 mL, with reported rates ranging from 4.8% to 30%. High-risk pregnancies, like those with advanced maternal age, assisted reproductive technology, multiple pregnancies, or placenta accreta spectrum disorders, are major contributors to the rising rates of PPH. Although there are risk assessment tools available for PPH, they are not universally proven, and around 60% of cases of PPH happen in women who lack risk factors.
