MSN570 WEEK 8 CASE STUDY GUIDE AND
COMPLETE SOLUTION
An 80 year old male presents with resolving decubitus, that are now
oozing and red. The wound team has been involved. His daughter
wants information regarding his skin condition.
1. Describe the phases of wound healing. ALEX
There are four basic phases of wound healing: 1. Hemostasis, 2.
Inflammatory, 3. Proliferative, 4. Remodeling or maturation. During
Hemostasis, vasoconstriction occurs to prevent the body from bleeding
out rapidly, this is achieved by platelets delivered to the site to form a
clot. Next, the inflammatory cells are activated, and the wound starts
to close. Neutrophils, cytokines and mediators promote the
development of new blood vessels, thrombosis, and epithelialization
(desJardins-Park,et al., 2018). Fibroblasts occur during this stage and
are critical in supporting normal wound healing. Fibroblasts break
down the fibrin clot, creating a new extracellular matrix, and collagen
structures to support the other cells (desJardins-Park et al.,2018). The
inflammatory stage can last many days, and is where many chronic
wounds cannot get past. The proliferative stage is where
neovascularization and re-epithelialization occur, and granulation
tissue forms (Singh & McNaught,2017). Cells involved in this phase
include-macrophages, fibroblasts, endothelial cells, mast cells, b-cells
and myofibroblasts; these different cells help recover the structure and
function and foundation of the wounded skin (Singh & McNaught,
2017). Excess collagen will begin to degrade, and wound contraction
begins to peak, that’s where the final stage takes place. The
remodeling phase usually takes place during the 3rd week, and can last
up to 12-24 months, depending on the patient’s age, comorbidities,
etc. The
