Infrared Thermographic Measurement of Long Term Circulatory Compromise in Trenchfoot Injured Argentine Soldiers

Passive rewarming of a cold water stressed foot was evaluated in 33 recovered trenchfoot (TF) patients and 15 uninjured men. Infrared images were recorded prior to immersion, immediately following and at 1 min intervals for 20 min. Individual baseline temperature (IBT) recovery was used to separate...

Description
Summary:Passive rewarming of a cold water stressed foot was evaluated in 33 recovered trenchfoot (TF) patients and 15 uninjured men. Infrared images were recorded prior to immersion, immediately following and at 1 min intervals for 20 min. Individual baseline temperature (IBT) recovery was used to separate subjects into three groups designated Good and Poor Rewarming Controls (GRC and PRC) and Injured Subjects (Inj Sub). IBTs were significantly less (p0.001) for Inj Sub when compared to both GRC and PRC while no difference existed between GRC and PRC. It could not be determined if the poor response of Inj Sub was inherent or a result of injury. We conclude that previously injured subjects and nearly 60% of a normal population may be at significant risk for cold injury.
