<abstract xmlns="http://www.w3.org/1999/xhtml"> Background: Rotational thrombelastometry (ROTEM) is a real-time clotting test that provides insight into clotting factors, the fibrinolytic system and platelet function. We obtained the longitudinal values on ROTEM in normal pregnancy and in puerperium.Material and Methods: After ethics committee approval and subject informed consent, citrated blood was sampled from healthy pregnants four times during pregnancy and one time postpartum. As controls we used nonpregnant women undergoing voluntary blood donation. Extem and Intem tests and basic coagulation test were carried out.Results: We included 112 women in our study, 55 non-pregnant women (controls) and 57 healthy pregnants with 5 samplings. The values of maximum clot firmness (MCF - in EXTEM and INTEM) were significantly higher up to 34th-36th week of pregnancy than those in non-pregnant subjects. MCF in 6th-7th week after delivery was significantly higher in both tests. Clotting time (CT) in pregnant women was significantly shorter (EXTEM) compared to non-pregnant subjects.
