Gas gangrene (also known as clostridial myonecrosis [1]) is a bacterial infection that produces tissue gas in gangrene. This deadly form of gangrene usually is caused by Clostridium perfringens bacteria. About 1,000 cases of gas gangrene are reported yearly in the United States. [2] Myonecrosis is a condition of necrotic damage, specific to ...
Gangrene itself happens when the tissue loses blood flow and becomes deprived of oxygen and nutrients. Without proper blood supply, cells in the affected area start dying, leading to decay. There are different types of gangrene, including dry, wet, and gas gangrene, depending on the underlying cause and the conditions of the tissue.
Chemical weapons have since washed up on shorelines and been found by fishers, causing injuries and, in some cases, death. Other disposal methods included land burials and incineration. After World War 1, "chemical shells made up 35 percent of French and German ammunition supplies, 25 percent British and 20 percent American". [96]
Both dry gangrene and gas gangrene can lead to this type of necrosis. If superimposed infection of dead tissues occurs, then liquefactive necrosis ensues (wet gangrene). [9] Caseous necrosis can be considered a combination of coagulative and liquefactive necrosis, [6] typically caused by mycobacteria (e.g. tuberculosis), fungi and some foreign ...
The German gas attack at Wulverghem on 30 April, caused the defenders 562 gas casualties and 89 gas fatalities but German raiding parties, looking for mine entrances to destroy, were repulsed with small-arms and artillery fire. A second attempt by the Germans on 17 June caused about the same number of gas casualties but the British again easily ...
If all devitalised tissue was removed, and there was no dead tissue left behind, the patient would not develop gas gangrene. If the patient already had gangrene, then he could only be saved by excision of all dead tissue, although even then he might die from multiple organ failure caused by release of powerful toxins. [15]
By late July 1915, 30 gas artillery batteries had been deployed to the German front lines, each equipped with several thousand gas shells. The use of gas was intended to dispose of the Russian garrison, which lacked adequate gas protection or masks. [2] The final assault plan called for multiple infantry units to advance after the gas had ...
German gas attacks were made at night or in the early morning, when the wind was favourable and darkness made it difficult for the defenders to see the gas cloud. [20] [b] Phosgene made the gas cloud more poisonous and the Germans tried to increase the concentration of the gas by discharging it quickly, though this reduced the duration of the ...
