tissue ischemia | is a restriction in blood supply to tissues, causing a shortage of oxygen and glucose needed for cellular metabolism (to keep tissue alive)/ generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue |
Vacuum-assisted closure (V.A.C.) | is a simple technique where a piece of foam with an open-cell structure is inserted into the wound, and a wound drain with lateral perforations is laid atop it |
wound | an injury to living tissue caused by a cut, blow, or other impact, typically one in which the skin is cut or broken.syn: injury, lesion, cut, gash, laceration, tear, slash |
wound contraction | is a process that may occur during wound healing when an excess of wound contraction, a normal healing process, leads to physical deformity characterized by skin constriction and functional limitations |
aerobic | relating to, involving, or requiring free oxygen. |
anaerobic | relating to, involving, or requiring an absence of free oxygen. |
asepsis | the absence of bacteria, viruses, and other microorganisms.-the exclusion of bacteria and other microorganisms, typically during surgery |
asymptomatic | (of a condition or a person) producing or showing no symptoms. |
bacteriostasis | abb. Bstatic, is a biological/chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise. Depending on their application, Bstatic antibiotics, disinfectants, antiseptics and preservatives can be distinguished |
