- Brief Summary
A new thromboelastometry analyser (ClotPro, Enicor GmbH, Munich, Germany) with improved technology was developed. This device has an improved new-generation viscoelastometric testing technique and enables the detection and assessment of factor deficiencies, low fibrinogen, platelet contribution (to whole blood coagulation), heparin and direct oral anticoagulants effects, fibrinolysis and antifibrinolytic drugs. This study aims to determine reference ranges for the ClotPro device for all paediatric age groups.
- Detailed Description
Viscoelastic testing as a relatively novel method to assess coagulation status appears favourable in reducing blood product transfusions. The tests are performed on whole blood instead of plasma, which saves time and gives a quick sight at the interaction between cellular and plasmatic clotting factors.
Reviews of the literature suggest that transfusions of packed red blood cells (pRBC), plasma, and platelets are all decreased in patients whose transfusions were guided by viscoelastic tests rather than by clinical judgement or conventional laboratory tests.
The benefits of viscoelastic coagulation monitoring have been described in many fields of surgery and intensive care. Current literature and a guideline for the treatment of massive haemorrhage in perioperative bleeding and trauma patients recommend the use of viscoelastic tests to guide haemostatic resuscitation.
