Hypothesis:
A second injury in the same body region is associated with lower mortality than a second injury in a different body region, independently of injury severity and body region.
Methods:
The population consisted of 15,200 patients with two or more injuries from level I trauma centers in Quebec. The mortality odds ratio of having a same-region second injury (SR) as opposed to a different-region second injury (DR) was assessed.
Results:
Patients with a SR had 43% lower odds of mortality when compared to patients with a DR.
Conclusion:
A second injury in the same body region is associated with lower mortality than a second injury in a different body region.

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
