Rotational thromboelastometry‐guided blood component use in cirrhotic children undergoing invasive procedures: Randomized controlled trial

This randomized controlled trial (RCT) was conducted with the aim to evaluate the efficacy and safety of using ROTEM-based transfusion strategy in cirrhotic children undergoing invasive procedures.This was an open-label, RCT which included (i) children under 18 years of age with liver cirrhosis; (ii) INR between 1.5 and 2.5; and/or (iii) platelet count between 20 × 10A total of 423 invasive procedures were screened for inclusion of which 60 were randomized (30 in each group with comparable baseline parameters). The volume of total blood components, fresh frozen plasma (FFP) and platelets transfused was significantly lower in ROTEM as compared to conventional group. Only 46.7% of children in ROTEM group received a blood component compared to 100% in conventional group (p .001). The requirement of FFP (ROTEM: 43.3%, Conventional: 83.3%, p = .001) was significantly lower in the patients receiving ROTEM-guided transfusions. There was no difference in procedure-related bleed and transfusion-related complications between the two groups. ROTEM was cost-effective (p = .002) despite the additional cost of the test.ROTEM-based transfusion strategies result in lower blood component transfusion in cirrhotic children undergoing invasive procedures without an increase in risk of procedure-related bleed. ROTEM-guided transfusion strategy is cost-effective.
