Bandaging helps to maintain a healthy environment for healing open wounds. Wound healing in animals: a review of physiology and clinical In protein-depleted animals, wound healing time is increased, mature collagen develops more slowly, tensile strength is decreased and spontaneous wound disruption occurs more frequently. If a wound is not healing: Reassess if you have the correct etiology. Systemic and local factors can influence a wound's microenvironment and thereby influence the progression of healing. The desired result of wound healing is for the two sides of a wound to heal together. d. the client; will they follow your instructions and recommendations?
