Cirrhosis, Operative Trauma, Transfusion, and Mortality: A Multicenter Retrospective Observational Study.

Abstract

Background: In trauma patients with cirrhosis who require laparotomy, little data exists to establish clinical predictors of the outcome. We sought to determine the prognosticators of mortality in this population.Methods: We performed a 10-year review at four, busy Level I trauma centers of patients with cirrhosis identified during trauma laparotomy. We compared vital signs, laboratory values, and transfusion requirements for those who survived versus those who died. A linear regression was then conducted to determine the variables associated with death in this population.Results: A total of 66 patients were included and 47% (31/66) died. The model for end-stage liver disease (MELD) score was low (7.8 in Lived, 10.2 in Died). Packed red blood cell (PRBC) transfusion at six hours was greater in those who died; those receiving > 6 units of PRBCs at 6 hours had an increased likelihood of death (odds ratio OR 5.8 (95% CI 1.9, 17.4)). All patients receiving ≥ 17 units of PRBCs died. We found an association between lower preoperative platelets (PLTs), higher preoperative international normalized ratio (INR) and partial thromboplastin time (PTT), lower preoperative pH (presence of profound acidemia), increased intraoperative crystalloid use, and increased intraoperative blood product administration to be associated with death (p < 0.05).Conclusions: Cirrhotic trauma patients requiring laparotomy should be considered to have a high chance of mortality if they receive six or more PRBCs, are acidotic (pH ≤ 7.25) at the time of hospital arrival, or have coagulopathy at the time of admission (INR > 1.2, PTT > 40).
