What would be the specific long term and short term outcomes of slashing wounds in microgravity?
The scenario is that a normal adult is slashed with a knife in a microgravity environment. Assume standard atmospheric pressure and normal atmospheric composition. Assume that the injury cuts through skin and moderate amounts of muscle. Assume the wound is taken on a thigh (ample musculature).
For instance:
A lack of gravity experienced during space flight has been shown to have profound effects on human physiology including muscle atrophy, reductions in bone density and immune function, and endocrine disorders (https://www.frontiersin.org/articles/10.3389/fcell.2020.00096/full).
Weightlessness is associated with blood flow stasis in internal veins. Blood flow stasis could lead to a lack of clotting materials and nutrients for normal healing ([https://www.google.com/amp/s/www.syfy.com/syfy-wire/human-blood-acts-weird-in-zero-g%3famp][1])
Microgravity has been shown to be detrimental to wound repair. Astronauts injured in space have a harder time healing. The cells cultured in microgravity and the cells cultured on earth will differ in gene expression. Blood vessel development will be impaired in cells cultured in microgravity (caution pdf) (https://www.google.com/search?q=wound+healing+in+micro+gravity&oq=wound+healing+in+micro+gravity+&aqs=chrome..69i57.17574j0j4&sourceid=chrome-mobile&ie=UTF-8)
