Trench foot
Trench foot can be prevented by keeping the feet clean, warm, and dry. It was also discovered in World War I that a key preventive measure was regular foot inspections; soldiers would be paired and each made responsible for the feet of the other, and they would generally apply whale oil to prevent trench foot. If left to their own devices, soldiers might neglect to take off their own boots and socks to dry their feet each day, but if it were the responsibility of another, this became less likely. Later on in the war, instances of trench foot began to decrease, probably as a result of the introduction of the aforementioned measures; of wooden duckboards to cover the muddy, wet, cold ground of the trenches; and of the increased practice of troop rotation, which kept soldiers from prolonged time at the front.
Transdermal continuous oxygen therapy
Animal studies conducted in 2004-2005 have demonstrated the effectiveness of TCOT on Rabbit ear wounds. A recently published study documented two prevented amputations which have shown TCOT to be highly effective on diabetic foot ulcers, venous stasis and decubitus ulcers and a study completed in 2010 by Dr. Gary Sibbald documented the effectiveness of TCOT on 9 diabetic foot ulcer patients. Manufacturers of devices used in TCOT have published several additional cases whereby treatment using TCOT prevented previously scheduled amputations.
