Aetiology and prognostic implication of severe jaundice in surgical trauma patients

Pronounced postoperative jaundice occurs not infrequently in trauma patients. The aim of this study was to elucidate the implication of early, pronounced jaundice (serum-bilirubin >100 micromol x l(-1)) for 30-day survival of such patients.

From 1995 through 2001, 53 surgical trauma patients developing pronounced postoperative jaundice were identified. Nine were excluded from the study because of major hepatobiliary injury or pre-existing liver disease. The clinical course and laboratory chemistry profiles of the remaining 44 patients were analysed.

Thirty-one patients survived and 13 died within 30 days of trauma. Non-survivors had higher age, higher injury severity score (ISS) and lower probability of survival (PS) (P < 0.05) than survivors. ISS averaged 34 in survivors and 45 in non-survivors. Survivors and non-survivors received a mean of 46 (range 10-97) and 55 units of blood (range 11-128), respectively (P = 0.366). Systemic hypotension, local infections and sepsis were common in both groups. Bilirubin levels peaked around the 11th day in survivors (median 189 micromol x l(-1)). In non-survivors, serum bilirubin values rose progressively, reaching maximum levels at time of death (median 231 micromol x l(-1)). These patients died in a setting of sepsis and multiple organ failure.

Large endogenous production of bilirubin because of rapid breakdown of transfused and extravasated blood can cause pronounced jaundice in multitransfused trauma patients. In such patients, serum bilirubin rising >100 micromol x l(-1) does not by itself signal poor outcome. However, progressive pronounced jaundice outlasting the trauma incident by 10-12 days portends fatal outcome for the patient.
