Point-of-care Coagulation Monitoring: Current Status of Viscoelastic Techniques

摘要: Hemostasis monitoring is becoming increasingly important in the management of bleeding patients operating room (OR) and intensive care unit (ICU) order to improve outcome reduce costs treatment. It has been shown cardiac surgery that frequent reassessment coagulation status transfusion according well-structured algorithms reduced blood loss component use when compared with regimens based on clinician discretion [1, 2]. Routine laboratory tests (e.g., prothrombin time [PT]/interna-tional normalized ratio [INR], activated partial thromboplastin [aPTT], fibrin-ogen) measure clotting times factors recalcified plasma after activation different activators. Platelet numbers are given complete overall assessment. Although values obtained by routine testing accurate, standardized, have used for a long time, their questioned assessment severely patient because measured plasma, no information platelet function available, there delay 30–60 min from sampling obtaining results.
