Immobilisation is key in packaging. It minimises serious pain (using bone splinting), serious morbidity (spinal cord injury) and mortality (dislodgment of formed clots). Splinting limb fractures minimises pain by eliminating unnecessary movement at fracture sites. Bringing bones back into anatomical alignment precludes the mobile ends of fractured bones from damaging blood vessels, causing further haemorrhage, and also reduces the area into which any torn blood vessels can bleed. ‘Clot and cord’ management can be grouped together, as the measures taken to prevent spinal cord damage also minimise clot disruption. Traditionally in the UK, spinal cord immobilisation involves the use of a cervical collar and blocks secured to a rigid spinal board with the patient log-rolled onto and off the board. However, in a consensus statement from the Faculty of Prehospital Care in 2013, Moss et al. (2013) have stated that the long spinal board should be used only as an extrication device, and not for patient transfer to hospital. While safeguarding against cord injury, the log-rolling required to move the patient onto and off the board risks causing further haemorrhage from disrupting the clots formed naturally (typically over a period of 10 minutes) by the patient’s coagulation cascade after trauma.
