Travma tahtasına bağlı oluşan basınç ve buna bağlı oluşan ağrının değerlendirilmesi ve azaltılmasına yönelik uygulanan visco elastik desteğin fizyomekanik sonuçları
Spinal backboard is routinely used in all major trauma cases. In this study, we aim to reduce discomfort and pressure pain, via enhancing the spinal backboard with viscoelastic support. Materials and Method: The inclusion criteria of this prospective study made eligible 20 volunteers. The first stage of the study was conducted in the Physical Therapy and Rehabilitation Department at Gulhane Military Medical Academy, the volunteers were asked to lie in the supine position on standard backboards with and without viscoelastic support for 5 minutes each. Occipital, scapular and sacral pressures were measured via pressure gauge matt (XSensor ®) as mm/Hg, in order to compare pressures per minute of both surface area of supported and supportless backboards. The second phase was composed of two periods of 60 minutes during while the volunteers lied supine on standard backboards with viscoelastic support and without viscoelastic support. The first 10 minutes of each periods took place in a moving ambulance, the volunteers stayed lying in the same supine position for the next 50 minutes in order to simulate real postaccident events. For evaluation of pain 10, 15, 30, 45 and 60 minutes VAS was used. Results: As a result, VAS comparison of subjects' visco elastic supported and unsupported trauma board in all interrogation minutes was statistically significant for general pain (p <0.001), occipital region (p <0.001), scapular region (p <0.001) and sacral region (p <0.001). Capillary refill pressure in the occipital region (p = 0.086), and in the scapular region (0,100) in comparison to the remaining surface of the entire surface under pressure were not significant in statistical evaluations in both visco-elastic supported and unsupported trauma board groups, but the sacral region statistical evaluation was significant (p <0.001). Conclusion: Viscoelastic support is an important tool for reducing pressure pains over the course of transport and follow up, especially when imaging times is prolonged. It is shown that patient comfort can be enhanced for a low cost and overall pain and unsuccesfull imaging attempts are thought to be reduced with decreasing pressure pains of trauma patients. Future studies should investigate viscoelastic support backboards role in pediatric trauma patients.
