骨盆骨折常由高能量创伤引起，死亡率高达10%，并发症严重。骨盆固定器应用于疑似骨盆损伤，以稳定骨折，减少出血和加强填塞。捆绑器必须以足够的力固定骨盆，以达到这种效果。本研究的目的是量化专有和即兴骨盆绑定器的能力，以保持一个目标的张力随着时间的推移。MethodsThe三个专有和三个即兴绑定器的能力，以保持约束力为2小时进行了测试。使用单轴材料试验机将每种粘合剂拉伸至150 N，然后保持位移2小时;记录每种粘合剂随时间的张力下降。保持张力高于130 N的能力，2小时后被设置为度量的粘合剂performance.ResultsThe中位数张力在2小时以上的SAM骨盆吊带II和T-POD骨盆稳定装置，并低于130 N的普罗米修斯骨盆夹板，现场权宜骨盆夹板（FES）和个人服装系统，多地形模式战斗裤粘合剂。2小时后，简易FES中的张力约为目标130 N;然而，在40%的测试中，它保持在130 N以上。结论在2小时的测试期间，固定器维持足够张力以治疗骨盆骨折的能力各不相同。FES在我们的测试制度下表现良好;由于成本和重量相对较低，它是严峻环境下专有粘合剂的良好替代品。
IntroductionPelvic fractures often result from high-energy trauma and are associated with a 10% mortality rate and significant morbidity. Pelvic binders are applied in suspected pelvic injury to stabilise fractured bone, decrease bleeding and potentiate tamponade. A binder must hold the pelvis with sufficient force for this effect to be achieved. This study aims to quantify the ability of proprietary and improvised pelvic binders to hold a target tensile force over time.MethodsThe ability of three proprietary and three improvised binders to hold a binding force for 2 hours was tested. A uniaxial materials testing machine was used to tension each binder to 150 N and then hold the displacement for 2 hours; the drop in tension over time was recorded for each binder. The ability to hold tension above 130 N after 2 hours was set as the metric of binder performance.ResultsThe median tension at 2 hours was above 130 N for the SAM Pelvic Sling II and T-POD Pelvic Stabilisation Device and was below 130 N for the Prometheus Pelvic Splint, field-expedient pelvic splint (FES) and the Personal Clothing System-Multi-Terrain Pattern Combat Trousers binders. The tension in the improvised FES after 2 hours was approximately at the target 130 N; however, in 40% of the tests, it held above 130 N.ConclusionsBinders varied in their ability to maintain sufficient tension to treat a pelvic fracture over the 2-hour testing period. The FES performed well under our testing regime; with relatively low cost and weight, it represents a good alternative to proprietary binders for the austere environment.
