“…In terms of the components of the GCS scale, a motor score of 2 or less was associated with the lowest survival. 5 Certain associated injuries, when combined with TBI carry an especially high mortality, including great vessel (50% mortality), liver (39%), bowel (37%), spleen (34%), lung (34%), spine (26-32%), and various skeletal injuries (18-29%). 21 Of note, many of these "high mortality" concurrent injuries tend to be associated with either blood loss and hemorrhage (i.e., femur fracture, splenic/hepatic laceration) or hypoxia (i.e., pulmonary injury).…”
