Pelvic Binding Device from Resistance Band and Bed Sheet

Abstract

Background Pelvic injuries are common in blunt injury mechanisms. Unstable pelvis fracture results in an increased pelvic volume that can accommodate a large volume of blood and rapid death. The pelvis can be stabilized with a binder or sheet to limit this expansion and control hemorrhage.
Objective To compare a pelvic binding device from resistance band and bed sheet and compare its effectiveness with commercial pelvic binding device.
Method Experimental study for comparing pelvic binding device from resistance band and bedsheet. Between 1st May -30th September 2021, twenty- four emergency medicine residents of Phramongkutklao hospital were enroll. This study was done in two consecutive parts. Firstly, the volunteers pulled the 25 kg resistance exercise band until reach an appropriate tension 150 N that able to hold the fracture. The stretching length were recorded. Secondly, the resistance band was assembled to bed sheet for creating a pelvic binding device. Then the volunteers were asked to apply the device to simulated patient with appropriate length. The time of applying was recorded comparing with commercial pelvic binding device (T-test).
Results The length that volunteers pulled the resistance band to reach 150 N was 12.22 ± 0.04 cm. The time for applying the pelvic binding device made from resistance band was 68.21 seconds, comparing to commercial device at 68.01 seconds (P-value 0.290).
Conclusion The pelvic binding device made from resistance band and bed sheet is effective for holding the pelvic fracture. The time use for applying this device comparing to commercial device was not different.
