What factors inhibit wound healing in older adults according to Kozier et al. in Chapter 36?

Factors inhibiting wound healing in older adults include vascular changes like atherosclerosis, less flexible collagen, less elastic scar tissue, changes in the immune system, nutritional deficiencies, chronic conditions like diabetes and cardiovascular disease, and slower cell renewal.

Wound healing in older adults is inhibited by several factors. Vascular changes such as atherosclerosis and capillary atrophy reduce blood flow to wounds, impairing healing. Collagen tissue becomes less flexible with age, increasing susceptibility to damage from pressure and friction. Scar tissue also becomes less elastic. The immune system's reduced ability to form antibodies and monocytes can hinder the healing process. Nutritional deficiencies can lead to fewer red blood cells and leukocytes, which are crucial for oxygen delivery and the inflammatory response necessary for healing. Chronic conditions like diabetes and cardiovascular disease further delay healing by impairing oxygen delivery to tissues. Additionally, the rate of cell renewal decreases, leading to slower healing.
