Insights
This study introduces a low-cost device for measuring pressure in compression garments used for treating hypertrophic scars. The findings indicate consistent pressure application across most body regions, aiding in effective scar management.
Area of Science:
- Biomedical Engineering
- Dermatology
- Trauma Surgery
Context:
- Hypertrophic scarring is a common complication of childhood burns and scalds.
- Compression therapy is a primary treatment for hypertrophic scars, but optimal pressure is unknown.
- Accurate pressure measurement is crucial for effective compression therapy.
Purpose:
- To evaluate a simple, inexpensive pressure measuring device for use with compression garments.
- To assess pressure distribution under compression therapy in pediatric burn patients.
- To determine if pressure varies significantly across different body regions.
Summary:
- A novel, low-cost (<100 Euro) pressure measuring device was developed using an air-filled balloon and piezoresistive sensor.
- Calibration demonstrated accuracy from 5 to 50 mmHg (p<0.001).
- Average pressure was 26.0+/-8.5 mmHg, with no significant differences across most body regions, except the cheek (12.3+/-1.3 mmHg, p<0.01).
- Tissue consistency (soft/hard) showed minor pressure differences (p<0.05).
Impact:
- Provides a practical tool for clinicians to ensure adequate and consistent pressure application during scar management.
- Facilitates further research into optimal pressure levels and application techniques for hypertrophic scars.
- Potentially improves treatment outcomes and reduces the incidence or severity of hypertrophic scarring in pediatric burn survivors.
Background:
Burns and scalds are among the most common traumas in childhood and more than often lead to hypertrophic scarring. Compression therapy is one of the main concepts in the prophylaxis and therapy for hypertrophic scars. However, the mode of action and the optimum value for pressure are still unknown. In this study, we evaluated the possibility of measuring the pressure under compression garments with a simple pressure measuring device.
Material And Methods:
Pressure generation occurred by an air-filled balloon connected to a piezoresistive pressure sensor, which showed the pressure as a value of voltage. Calibration was possible with p
Results:
With an overall average pressure of 26.0+/-8.5 mmHg, no body region showed significantly different pressures. Only the pressure values on the cheek were significantly lower with 12.3+/-1.3 mmHg, (p
Conclusion:
We have developed a cheap (<100 Euro) and simple technique to measure the pressure during compression therapy. Further studies with a larger number of patients will follow.
