Summary
Viscoelastic tests like thromboelastography (TEG) and rotational thromboelastometry (ROTEM) assess blood clotting. This review examines their use in guiding transfusions during hepatic surgery to reduce blood product needs.
Area of Science:
- Anesthesiology
- Hematology
- Surgical Sciences
Background:
- Viscoelastic tests, including TEG and ROTEM, offer point-of-care assessment of hemostasis.
- Previous studies suggest TEG/ROTEM can reduce transfusions in certain surgical contexts.
- Hepatic surgery patients face high risks of blood loss and coagulopathy.
Purpose of the Study:
- To systematically review evidence on viscoelastic testing in hepatic surgery.
- To evaluate the efficacy of TEG/ROTEM in guiding blood product administration.
- To assess the impact on transfusion requirements and patient outcomes.
Main Methods:
- Comprehensive database search (MEDLINE, EMBASE, Cochrane).
- Inclusion of randomized controlled trials on viscoelastic testing for hepatic surgery.
- Independent data extraction and meta-analysis if feasible.
Main Results:
- This section is to be populated upon completion of the review.
- Expected findings relate to transfusion reduction and patient outcomes.
- Potential benefits include rationalized blood use and reduced complications.
Conclusions:
- Viscoelastic testing is increasingly available as a bedside tool.
- Evidence is needed to confirm benefits in hepatic surgery.
- This review will summarize current data on TEG/ROTEM in this setting.
