Abstract
Background: Pelvic Circumferential Compression Device (PCCDs) aids in temporary stabilisation of pelvic injuries, in a decrease of pelvic volume and thereby assisting in haemostasis. It is known that if PCCDs are applied for extended duration, damage to tissue can occur. This research helps to quantify the pressure exerted by two different PCCD (SAM Sling® and T-POD®) at four locations (anterior, right, left and sacral) in healthy volunteers.
Methods: SAM sling® and T-POD® were applied randomly on healthy volunteers and mean pressures was measured at locations (anterior, right, left and sacral) by pressure cuffs.
Results: A significant variation was noted in the pressure exerted by both PCCDs at the four locations. Pressures exerted at anterior locations were less than tissue damaging pressure of 9.3 kPa for both SAM Sling® and T-POD®. For volunteers with higher BMI the pressure exerted at right and left greater trochanter was greater than the tissue damaging pressure of 9.3 kPa for both SAM Sling® and T-POD®. However, the SAM-Sling® produced higher mean pressures on the left location as compared to the right location while T-POD® produced higher mean pressures on the right location as compared to the left location. This can be attributed to the different closing mechanism of both the PCCDs. Pressure exerted at the sacral location was always greater than the tissue damaging pressure of 9.3 kPa for both the PCCDs.
Conclusion: The results of this study in healthy volunteers presented that application of PCCD is associated with the development of high mean pressure at the right greater trochanter, left greater trochanter and sacral region and may lead to formation of pressure sores. However further research with a higher number of volunteers and testing of the results of this study in acute clinical scenario is needed to ascertain these findings from the current study.
