Postpartum Haemorrhage (PPH)

This prospective observational, non-interventional, single-center study aims to evaluate whether the viscoelastic parameter PLTEM, derived from ROTEM® sigma testing (EXTEM-A5 minus FIBTEM-A5), can accurately estimate platelet count in obstetric patients with thrombocytopenia and/or severe postpartum hemorrhage. The study will include pregnant women older than 18 years managed during labor and delivery at the Hospital General Universitario Gregorio Marañón, Madrid (Spain). The primary objective is to validate the clinical usefulness of PLTEM as a rapid point-of-care tool to support clinical decision-making regarding neuraxial anesthesia and transfusion management in obstetric emergencies.

abnormal bleeding after childbirth. This condition is called abnormal bleeding and becomes a condition known as postpartum hemorrhage (PPH) when worsens. Abnormal bleeding is defined as the loss of more than 500 milliliters (about two cups) of blood after a vaginal birth, or more than 1,000 milliliters (about four cups) after a cesarean section. It is a serious and potentially life-threatening complication that requires immediate medical treatment. What you need to know: * Signing this form does not mean you will have an emergency postpartum bleeding. * We will only include you in the study IF abnormal bleeding happens after your birth. * If abnormal bleeding does happen, your doctors will first try the usual treatments that work in accordance with the hospital's PPH protocol. * The study device (called Alma system) would only be used if the usual treatments do not stop the bleeding. Treatment Schedule - Recruitment \& Consenting * Screening and enrolment. * Treatment of PPH with Alma system. * Alma Survey * Follow up examination post treatment procedure (after removal of Alma system and before subject discharge from the hospital). * 6-week postpartum follow-up examination.
