Analyzing Risk Factors for Wound Infection in Slow-Healing Leg Wound

This case study examines the risk factors associated with wound infection in a patient with a slow-healing leg wound. It explores local factors such as oxygenation, venous and arterial insufficiencies, and the risk of exposure to infection due to frailty and reduced eyesight. Systematic factors including age, comorbidities, medications, and nutrition are also analyzed. The case highlights how these factors can compromise the immune system, delay healing processes, and increase the susceptibility to wound infection. References to relevant research articles are included to support the analysis. Desklib provides access to this and other solved assignments to aid students in their studies.

Local Factors
Oxygenation
Oxygen is essential for all wound healing processes. However, several systematic
conditions such as comorbidities such as the one presented by the patient might affect vascular
flow, impeding tissue oxygenation (Bui, Edwards, & Finlayson, 2016; Kihla, NgundeMbianda,
Nkwelang, & Ndip, 2014). The poor perfusion creates a hypoxic which predispose the tissues to
necrotic effects and infection.
Venous and Arterial Insufficiencies
Impaired vascular flow such as the one experienced by arthritis patient hinders blood flow and
interferes with wound oxygenation (Bui et al., 2016; Kihla et al., 2014). Reduced oxygenation is
a risk factor to wound infection.
Infection
Norma appears physically frail, unsteady on her feet, needs a walking frame and has reduced
eyesight. These factors might interfere with personal hygiene and expose the wound to infection
(Bui et al., 2016).
Systematic Factors
Age
Increased age increases the risk of impaired wound healing and exposes the wound to
infection (Bui et al., 2016; Kihla et al., 2014). Old-aged patients such as Mrs. Noma experience
altered inflammatory responses such as reduced macrophage phagocytic, lymphocytic, and other
immune responses capacity. Also, old age is associated with delayed angiogenesis and collagen

deposition and reduced remodeling which work in tandem to increase the risk of wound
infection.
Comorbidities and Medications
Mrs. Noma medical history shows her immune system is already compromised thus
exposing the chronic wound to infection (Bui et al., 2016; Kihla et al., 2014). The diseases Mrs.
Noma has suffered from have to be treated with medication, including the current Barret
esophagus. Medication such as antibiotics and NSAIDs (aspirin, ibuprofen) affect wound healing
and expose the wound to infection (Bui et al., 2016).
Nutrition
Poor nutrition induces reduced wound healing (Kihla et al., 2014). In old-people such as
Mrs. Noma, chances are her nutritional aspect has been affected by her old age and responsibility
to her son Michael.
