Background  To test whether an acute transfusion practice of packed red blood cells (pRBC) : fresh-frozen plasma (FFP) 1 : 1 would be associated with reduced mortality in acute bleeding multiply injury.

Methods  Retrospective analysis using the TR-DGU database (Trauma Registry of the Deutsche Gesellschaft für Unfallchirurgie 2002–2006) on primary admissions with substantial injury (Injury Severity Score > 16) and massive transfusion (> 10 pRBCs). Seven hundred thirteen patients were divided into three groups according to the pRBC : FFP ratio transfused, that is, (i) pRBC : FFP > 1·1; (ii) pRBC : FFP 0·9–1·1 (1 : 1); and (iii) pRBC : FFP < 0·9, and mortality rates were compared.

Results  Four hundred ninety-seven (69·7%) of patients were male, the mean age was 40·1 (± 18·3) years. Injury characteristics and pathophysiological state upon emergency room arrival were comparable between groups. Out of 713, 484 patients had undergone massive transfusion with pRBC : FFP > 1·1, 114 with pRBC : FFP 0·9–1·1 (1 : 1), and 115 with pRBC : FFP < 0·9 ratios. Acute mortality (< 6 h) rates for pRBC : FFP > 1·1, pRBC : FFP 0·9–1·1 (1 : 1), and pRBC : FFP < 0·9 ratios were 24·6, 9·6 and 3·5% (P < 0·0001), 24-h mortality rates were 32·6, 16·7 and 11·3% (P < 0·0001), and 30-day mortality rates were 45·5, 35·1 and 24·3% (P < 0·001). The frequency for septic complications and organ failure was higher in the pRBC : FFP 0·9–1·1 (1 : 1) group, ventilator days and length of stays for intensive care unit and overall in-hospital were highest in the pRBC : FFP < 0·9 ratio group (P < 0·0005).

Conclusions  An association between pRBC : FFP transfusion ratios and mortality to favour early aggressive FFP administration was observed. Further investigation is necessary prior to recommending routine 1 : 1 or more aggressive FFP use in exsanguinating patients.
