Hematoma formation after venipuncture impairs elderly skin barrier function, reducing hydration and elasticity. These sites require specialized moisturizing care, irrespective of erythema intensity.
Area of Science:
- Geriatric Medicine
- Dermatology
- Nursing Care
Background:
- Hospitalized elderly patients are susceptible to skin barrier dysfunction.
- Venipuncture is a common procedure in elderly care, often leading to hematoma formation.
- Understanding the impact of hematoma on skin integrity is crucial for effective patient care.
Purpose of the Study:
- To evaluate the effect of venipuncture-induced hematoma on skin barrier function in elderly patients.
- To compare skin barrier parameters between hematoma sites and surrounding non-hematoma skin.
- To inform improved skincare protocols for hospitalized elderly individuals.
Main Methods:
- Inclusion of 50 elderly patients (median age 84 years).
- Assessment of skin barrier function including transepidermal water loss (TEWL), sebum levels, stratum corneum hydration, skin elasticity, and skin pH.
- Comparison of these parameters between hematoma sites and adjacent non-hematoma sites.
- Correlation analysis with skin erythema intensity.
Main Results:
- No significant differences in TEWL or sebum levels between hematoma and non-hematoma sites.
- Significantly lower stratum corneum hydration and skin elasticity at hematoma sites compared to non-hematoma sites.
- Significantly higher skin pH at hematoma sites.
- No significant correlation found between study variables and skin erythema intensity.
Conclusions:
- Hematoma formation following venipuncture negatively impacts the skin barrier function in elderly patients.
- Reduced skin hydration and elasticity, along with altered pH, characterize hematoma sites.
- These findings underscore the need for targeted moisturizing skincare for hematoma sites, regardless of erythema severity.
