Foam overlays significantly reduce pressure in children, preventing pressure sores. Optimal protection shifts from the occipital to the sacral area as children age, requiring age-specific pressure relief strategies.

Area of Science:

  • Biomedical Engineering
  • Pediatric Nursing
  • Rehabilitation Medicine

Background:

  • Pressure sores are a concern in pediatric care.
  • Standard mattresses may not adequately relieve pressure in children.
  • Age-related changes in body structure influence pressure distribution.

Purpose of the Study:

  • To evaluate the effectiveness of 2-inch and 4-inch convoluted foam overlays in reducing interface pressures in children.
  • To identify age-dependent pressure points in pediatric patients.
  • To inform pediatric pressure injury prevention strategies.

Main Methods:

  • Interface pressures were measured on 13 healthy children (10 weeks to 13.5 years).
  • Measurements were taken on a standard mattress and 2-inch and 4-inch foam overlays.

  • Pressure points assessed included occipital, sacral, and scapular areas.

    • Main Results:

    • Significant pressure reduction was observed with foam overlays compared to standard mattresses (p < .001).
    • Highest pressures were initially recorded on the occiput, decreasing with overlay use.
    • Pressure migrated to the sacral area in older children and those with larger body surface area.

    Conclusions:

    • Convoluted foam overlays are effective in mitigating interface pressures in pediatric populations.
    • Pressure distribution and peak pressure sites change with age in children, shifting from occipital to sacral areas.
    • Pediatric pressure injury prevention requires age-specific interventions distinct from adult protocols.
