DIC Syndrome
Conditions
Brief summary
Evaluation of the use of thromboelastometry for early identification of the underlying coagulopathy and to guide individualized transfusion therapy to prevent DIC development during ICU stay after cesarean section in women with placenta previa who require a massive blood transfusion.
Detailed description
Placenta previa is defined as complete or partial implantation of the placenta in the lower segment of the uterus, Patients present with bleeding per vagina occurring usually in the second and third trimester. Bleeding in placenta previa is associated with maternal morbidity and mortality. Transfusion therapy is integral in the acute management of major obstetric hemorrhage. The most important pregnancy related condition leading to bleeding with high mortality and morbidity rates is DIC. Patients exhibit a tendency for severe bleeding associated with the consumption of platelets and coagulation factors. Massive blood transfusions are listed as the main maternal morbidity indicators6.Therefore, early detection of these predictors of DIC and timely intervention of this life-threatening condition is very important. DIC is a clinical-laboratory diagnosis, and laboratory changes need to be interpreted with knowledge of the patient's underlying disorder. Several laboratory parameters are analyzed together as part of a diagnostic algorithm that includes: Prothrombin time (PT), Activated partial thromboplastin time (aPTT), the platelet count, fibrinogen level, and a marker of fibrin degradation, e.g., D-dimer or the soluble fibrin monomer (SFM) 8. None of these markers are taken in isolation, and a combination of results at different time points is particularly helpful in determining the presence of DIC, owing to the multifaceted nature of DIC9, These reasons highlight a strong need for the development of a point-of-care testing system to accurately and reliably diagnose DIC. Thromboelastography (TEM) provides an extended reflection of clot initiation, propagation, and lysis in whole blood. TEM uses three tests: FIBTEM to reveal impaired fibrinogen function, INTEM to reveal coagulation factor deficiency and EXTEM to reveal extrinsic pathway defects
