Survival time and acting capability after fatal injury by sharp weapons.

Autopsy reports from 109 victims of fatal injury from sharp weapons were investigated with regard to type and number of lesions, blood loss, degree of alcohol intoxication, survival time and acting capability after the injury. Of the 13 who died immediately, nine had penetrating lesions of the heart. This group also had the highest number of lesions. Sixty-four victims survived for some time. The survival time increased with decreasing number of lesions. The greatest blood loss and the highest blood alcohol concentrations were found in those who survived between 0.5 h and 1 h. Twenty-four victims were able to make physical efforts after the injury and the movements varied from a few steps to the running of several hundred meters. Decisive factors for decrease in survival time and acting capability are penetrating lesions to the heart and the great vessels, and multiplicity of injuries.
