TABLE 4.
Demographics and resuscitation for all survivable injured patients versus those with anatomically non-survivable injuries to identify predictive factors for anatomically non-survivable injuries. There is a preponderance of blunt injury, depressed GCS, and elevated blood pressure in the non-survivable injured group.
