Estimating Platelet Counts with ROTEM PLTEM in Laboring Women with Low Platelets or Heavy Bleeding

Official title: Prediction of Platelet Function Using Viscoelastic Test (ROTEM® Sigma) in Obstetric Anesthesia: an Prospective Observational Study

Run by Hospital General Universitario Gregorio Marañon · NCT07616349 · Data updated 2026-11-12

This study tests whether the PLTEM value from ROTEM sigma testing can quickly estimate platelet count in pregnant women with low platelets or severe postpartum hemorrhage to help decisions about anesthesia and transfusions.

Is this trial a fit for you?

Likely a good fit

Pregnant women aged 18 or older managed during labor and delivery who have suspected or confirmed thrombocytopenia (platelets <120x10^9/L) or severe postpartum hemorrhage (>1500 mL).

Probably not a fit

Patients without thrombocytopenia or severe hemorrhage or those whose PLTEM does not correlate with platelet count may not benefit from this approach.

What this trial studies

This is a prospective, single-center, observational study conducted at Hospital General Universitario Gregorio Marañón in Madrid. It will measure PLTEM, calculated as EXTEM-A5 minus FIBTEM-A5, to see how well it reflects platelet count in obstetric patients with thrombocytopenia and/or severe postpartum hemorrhage. No interventions are performed; the study observes current clinical management and outcomes. The goal is to determine if PLTEM can serve as a rapid point-of-care tool to support neuraxial anesthesia decisions and transfusion strategies in obstetric emergencies.

Why it matters

Potential benefit: If PLTEM reliably estimates platelet count, clinicians could make quicker, safer decisions about anesthesia and blood product use during obstetric emergencies.

How similar studies have gone: ROTEM-based platelet assessments have shown promise in other settings, but validation in obstetric patients is limited and still evolving.
