The purpose of this study was to characterize the cause of death in severely injured trauma patients in order to define potential responses to resuscitation. Prospective analysis of 190 critically-injured patients who underwent massive transfusion protocol activation (MTP) or received massive transfusion (MT; greater than 10 units of packed red blood cells (pRBC)/24 hours). Cause of death was adjudicated into one of four categories: 1) Exsanguination, 2) Early physiologic collapse, 3) Late physiologic collapse, and 4) Non-survivable injury. 190 patients underwent MT or MTP with 76 deaths (40% mortality) of which 72 deaths were adjudicated to one of four categories: 33.3% died from exsanguination, 16.6% died from early physiologic collapse, 11.1% died from late physiologic collapse, while 38.8% died from non-survivable injuries. Patients who died from exsanguination were younger and had the highest RBC:FFP ratio (2.97 ± 2.24), although the early physiologic collapse group survived long enough to use the most blood products (p<0.001). The late physiologic collapse group had significantly fewer penetrating injuries, was older, and had significantly more crystalloid use, but received a lower RBC:FFP ratio (1.50 ± 0.42). Those who were determined to have a non-survivable injury had a lower presenting GCS, fewer penetrating injuries, and higher initial blood pressure reflecting a preponderance of non-survivable traumatic brain injury. The average survival time for patients with potentially survivable injuries was 2.4 hrs versus 18.4 hours for non-survivable injuries (p<0.001). Severely injured patients requiring MTP have a high mortality rate. However, no studies to date have addressed the cause of death after MTP. Characterization of cause of death will allow targeting of surgical and resuscitative conduct to allow extension of the physiologic reserve time therefore rendering previously non-survivable injury potentially survivable.
