Evaluation of the conventional stretcher as a support surface

M E Lovell1, P Bradshaw

  • 1208 General Hospital RAMC(V), Liverpool, UK.

Injury
|December 1, 1993
PubMed
Summary

Conventional stretchers cause discomfort and pose risks of pressure damage, similar to other support surfaces. Mean sacral interface pressure was 40.7 mmHg, with patients noting coldness and discomfort, especially on heels and lower back.

Area of Science:

  • Biomedical Engineering
  • Orthopedics
  • Patient Comfort Studies

Background:

  • Conventional wood and canvas stretchers are widely used in healthcare settings.
  • Assessment of patient comfort and potential for tissue damage is crucial for medical devices.
  • Limited data exists on the specific interface pressures and subjective experiences associated with these stretchers.

Purpose of the Study:

  • To evaluate the comfort and risks of pressure-related and ischemic damage associated with conventional wood and canvas stretchers.
  • To quantify the interface pressures experienced by subjects using these stretchers.
  • To compare the findings to existing data on other support surfaces.

Main Methods:

  • Sixty subjects were enrolled in the study.
  • Interface pressures, specifically mean sacral interface pressure, were measured.
  • Subjective feedback on comfort, temperature, and specific areas of discomfort was collected.

Main Results:

  • The mean sacral interface pressure was recorded at 40.7 mmHg.
  • Subjects reported the stretchers felt cold and uncomfortable.
  • Discomfort was particularly noted over the heels and lower back regions.

Conclusions:

  • Conventional stretchers present similar pressure and comfort issues as other support surfaces.
  • The identified interface pressures and subjective discomfort warrant consideration in stretcher design and patient care protocols.
  • Further research may explore alternative materials or designs to improve patient comfort and reduce tissue pressure risks.
