Combat Trousers as Effective Improvised Pelvic Binders A Comparative Cadaveric Study

Terrorist acts occur every day around the world. Healthcare professionals are often present as bystander survivors in these situations, with none of the equipment or infrastructure they rely on in their day-to-day practice. Within several countries there has been a move to disseminate the actions to take in the event of such attacks: in the UK, , and in the USA, This paper outlines how a very basic medical knowledge combined with everyday high-street items can render highly effective first aid and save lives. We discuss and summarise modern improvised techniques. These include the ABCDE approach of treating catastrophic haemorrhage before airway management, bringing together improvised techniques from the military and wilderness medicine. We explain how improvised tourniquets, wound dressings, splinting and traction devices can be fabricated using items from the high street: nappies, tampons, cling film, duct tape and tablecloths. Cervical spine immobilisation is a labour-intensive protocol that is often practised defensively. With little evidence to support the routine use of triple immobilisation, this should be replaced with a common sense dynamic approach such as the Montana neck brace. Acid or alkali attacks are also examined with simple pragmatic advice. Analgesia is discussed in the context of a prehospital setting. Pharmacy-obtained oral morphine and diclofenac suppositories can be used to treat moderate pain without relying on equipment for intravenous/intraosseous infusion in prolonged hold situations. The differentiation between concealment and cover is summarised: scene safety remains paramount.

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.

Chinese expert consensus on echelons treatment of pelvic fractures in modern war

et al. 2018

The characteristics and treatment of pelvic fractures vary between general conditions and modern war. An expert consensus has been reached based on pelvic injury epidemiology and the concepts of battlefield treatment combined with the existing levels of military medical care in modern warfare. According to this consensus, first aid, emergency treatment and early treatment of pelvic fractures are introduced in three separate levels. In Level I facilities, simple triage and rapid treatment following the principles of advanced trauma life support are recommended to evaluate combat casualties during the first-aid stage. Re-evaluation, further immobilization and fixation, and hemostasis are recommended at Level II facilities. At Level III facilities, the main components of damage control surgery are recommended, including comprehensive hemostasis, a proper resuscitation strategy, the treatment of concurrent visceral and blood vessel damage, and battlefield intensive care. The grading standard for evidence evaluation and recommendation was used to reach this expert consensus.
