Assessment of Obese Patients
Because obese patients carry heavier body weight, specific body parts endure greater pressure when lying down or sitting. Deep skin folds are prone to moisture and increased friction, making the skin highly susceptible to damage. Accompanying metabolic issues, such as abnormal blood sugar and lipids, can also impair the skin's nutritional supply and healing ability. Consequently, obese patients have a relatively higher risk of developing pressure ulcers, making active prevention essential.
BMI Calculation and Obesity Classification BMI is the universal standard for assessing systemic obesity, calculated as Weight (kg) / Height (m)^2. To guide clinical treatment, obesity is classified as follows:
l Mild Obesity: 28.0 kg/m^2 ≤ BMI < 32.5 kg/m^2.
l Moderate Obesity: 32.5 kg/m^2 ≤ BMI < 37.5 kg/m^2.
l Severe Obesity: 37.5 kg/m^2 ≤ BMI < 50 kg/m^2.
l Extremely Severe Obesity: BMI ≥ 50 kg/m^2.
Routine Skin Fold Examinations Caregivers must provide ample assistance to thoroughly check all skin surfaces and folds, as ulcers can occur over bony prominences or on buttocks and other fat-rich tissues due to pressure. It is critical to differentiate skin fold dermatitis from early-stage pressure ulcers:
l Skin Fold Dermatitis: Often related to incontinence, occurring in folds (perineum, buttocks) as diffuse, spotty lesions with irregular edges, red/pink color, and itching or burning.
l Stage I Pressure Ulcer: Intact skin presenting with non-blanchable redness, sometimes showing purple or maroon color changes.
l Stage II Pressure Ulcer: Partial-thickness skin loss involving the dermis, presenting as a ruptured blister or open wound.
Bed and Equipment Selection
Ensure the bed matches the patient's size and weight capacity by meeting specific criteria:
l Capable of safely supporting the patient's weight while being wide enough to allow turning without hitting the side rails.
l Equipped with a breathable support surface that offers enhanced pressure redistribution, shear force reduction, and microclimate control.
l Designed with automated turning functions, as turning obese patients manually is difficult and can lead to back pressure issues.
l Wheelchairs and seats must be sufficiently wide and paired with pressure-redistributing cushions designed specifically for seated obese patients.
l Walkers, overhead trapezes, and other mobility aids should be provided to encourage independence and movement.
l Support surfaces and cushions must be routinely checked for "bottoming out" points.
Posture and Nutrition
Positioning Adjustments
l Avoid letting tubes, medical devices, or foreign objects press against the skin during posture adjustments.
l Use pillows or positioning devices to offload pressure from skin folds and prevent skin-on-skin compression.
Nutritional Support Despite their larger size, obese patients may still lack the necessary nutrition to heal pressure ulcers. Patients should be referred to a registered dietitian for a comprehensive nutritional assessment and weight control plan.
l Protein: Essential for tissue repair, immune function, and collagen synthesis (lean meats, fish, eggs, beans, dairy).
l Vitamin C: Crucial for collagen synthesis and tissue repair (citrus fruits, berries, tomatoes, leafy greens).
l Zinc: Important for wound healing and immunity (oysters, beef, poultry, beans, nuts); intake must be monitored by a dietitian as excess can inhibit healing.
l Iron: Vital for oxygen transport in the blood, aiding wound healing (lean meats, beans, nuts, leafy greens).
CIITTO Medical Solutions
Xiamen CIITTO Medical Technology Co., Ltd. focuses on the R&D and manufacturing of highend medical equipment, including medical electric transfer carts, electric hospital beds, and anti-bedsore electric nursing beds.
The Anti-Bedsore Electric Nursing Bed is explicitly designed for long-term bedridden patients. Beyond automated posture changing, it features a built-in weighing function to monitor weight changes in real-time. This provides medical staff with critical data to evaluate the patient's nutritional status and significantly lowers the risk of bedsores.
Prevention is always better than cure; utilizing the correct assistive devices can drastically reduce the incidence of pressure ulcers. If potential symptoms appear, seek medical attention promptly to formulate a personalized care plan.
