The Sensitivity and Specificity of Rotational Thromboelastometry (ROTEM) to Detect Coagulopathy During Moderate and Severe Postpartum Hemorrhage: A Prospective Observational Study

( Int J Obstet Anes . 2022;49:103238) Viscoelastometric hemostatic assays, such as rotational thromboelastometry (ROTEM), offer rapid, point-of-care identification of coagulopathy during postpartum hemorrhage (PPH). Previous studies investigating the use of ROTEM have used a Delta ROTEM device. This study investigates the use of the ROTEM Sigma device, identifying the sensitivity, specificity, and positive or negative predictive values in patients with PPH.
