Summary
Lowering mouldable mattress pressure can harm the spinal cord. New mattress designs and immobilization techniques can mitigate this risk by reducing stress on the body.
Area of Science:
- Biomechanics
- Medical Device Engineering
Context:
- Mouldable mattresses, when deflated, can exert harmful forces on the spinal cord.
- Understanding the biomechanical forces during mattress deflation is crucial for patient safety.
Purpose:
- To quantify the axial forces exerted by deflated mouldable mattresses on human cadavers and volunteers.
- To evaluate the effectiveness of a prototype mattress in reducing these forces.
Summary:
- Axial forces were measured using stress gauges on a metallic manikin, cadaver (T2-L1), and volunteer volunteers' cephalic tops under reduced mattress pressure.
- Significant stress was observed, with values up to 484 N for the manikin, 150 N for the cadaver, and 102 N for volunteers.
- A prototype mattress showed improved results on metallic models but not on human subjects, indicating the complexity of in vivo biomechanics.
Impact:
- Provides critical data on the biomechanical risks associated with deflated mouldable mattresses.
- Informs the development of safer patient immobilization strategies and novel stress-reducing mattress designs.
- Enhances understanding of spinal cord stress mechanisms during medical procedures.
