Background & Aims:
Periprocedural blood component(s) prophylaxis is common in patients with cirrhosis undergoing invasive procedures. We evaluated whether a rotational thromboelastometry (ROTEM)-guided algorithm could reduce prophylactic transfusions without increasing bleeding complications.
Methods:
In this randomized controlled trial, adults with cirrhosis scheduled for invasive procedures with abnormal international normalized ratio and/or platelet count values requiring preprocedural correction as per standard local practice were randomized 1:1 to a ROTEM-guided or standard-of-care (SOC) transfusion strategy. The primary efficacy outcome was the proportion of procedures that required prophylactic transfusion of blood components(s). The primary safety outcome was major procedure-related bleeding. Secondary outcomes included type and volume of blood products transfused, transfusion reactions, thrombosis, and 28-day mortality.
Results:
A total of 114 procedures in 99 patients were screened with 57 randomized (28 in ROTEM, 29 in SOC). Forty-four procedures (77%) were classified as having a high bleeding risk. Prophylactic blood products were administered before 20 procedures in the ROTEM group compared with 28 in the SOC group (71% vs 97%; P < .01). The pattern of blood product use differed between the groups, with less fresh frozen plasma and more cryoprecipitate in the ROTEM group than in the SOC group. There was no difference in procedure-related bleeding (no major bleeding was recorded), thrombosis, transfusion-related complications, length of stay, or mortality between the 2 groups.
Conclusions:
ROTEM-guided transfusion significantly reduced blood product use without compromising safety in patients with cirrhosis undergoing invasive procedures. These findings support a more conservative, goal-directed approach to periprocedural hemostatic management in patients with cirrhosis.
