Immobilisers are short backboards that can be applied to a patient sitting in a car seat whilst the head and neck are supported in the neutral position quality 100mg kamagra effervescent erectile dysfunction neurological causes. In some cases the roof of the vehicle is removed or the back seat is lowered to allow a full-length spinal board to be slid under the patient from the rear of the vehicle discount 100mg kamagra effervescent amex erectile dysfunction natural shake. A long board can also be inserted obliquely under the patient through an open car door, but this requires coordination and training as the casualty has to be carefully rotated on the board without twisting the spine, and then be laid back into the supine position. Spinal immobilisers do not effectively splint the pelvis or lumbar spine but they can Figure 2. If the correct collars or splints are (Kendrick extrication device) in not available manual immobilisation of the head is the safest position. Small children can be splinted to a child seat with good effect—padding is placed as necessary between the head and the side cushions and forehead strapping can then be applied. If lying free, the casualty should ideally be turned by four people: one responsible for the head and neck, one for the shoulders and chest, one for the hips and abdomen, and one for the legs. This team can work together to align the spine in a neutral position and then perform a log roll allowing a spinal board to be placed under the patient. Alternatively the patient can be transferred to a spinal board using a “scoop” stretcher which can be carefully slotted together around the casualty. In the flexion-extension axis, the neutral position of the cervical spine varies with the age of the patient. The relatively large head and prominent occiput of small children (less than 8 years of age) pushes their neck into flexion when they lie on a flat surface. This is corrected on paediatric spinal boards by thoracic padding, which elevates the back and restores neutral curvature. Conversely, elderly patients may have a thoracic kyphosis and for this a pillow needs to be inserted between the occiput and the adult spinal board if the head is not to fall back Figure 2. In all instances, the aim is to achieve normal cervical curvature for the individual. For example, extension should not be enforced on a patient with fixed cervical flexion attributable to ankylosing spondylitis. One alternative is a vacuum splint (adult lower limb size) which can be wrapped around the child like a vacuum mattress (see below). However, an uncooperative or distressed child might have to be carried by a paramedic or parent in as neutral a position as possible, and be comforted en route. For transportation, the patient should be supine if conscious or intubated. In the unconscious patient whose (a) (b) airway cannot be protected, the lateral or head-down positions Figure 2. The flexion can be relieved by inserting padding under the neck on the spinal board, the semirigid collar must be the thoracic spine (b). Only the physically uncooperative or thrashing patient is exempt from full splintage of the head and neck as this patient may manipulate the cervical spine from below if the head and neck are fixed in position. In this circumstance, the patient should be fitted with a semirigid collar only and be encouraged to lie still. Such uncooperative behaviour should not be attributed automatically to alcohol, as hypoxia and shock may be responsible and must be treated. If no spinal board is used and the airway is unprotected, the modified lateral position (Figure 1. In the absence of life-threatening injury, patients with spinal injury should be transported smoothly by ambulance, for reasons of comfort as well as to avoid further trauma to the spinal cord. They should be taken to the nearest major emergency department but must be repeatedly assessed en route; in particular, vital functions must be monitored. In transit the head and neck must be maintained in the neutral position at all times. If an unintubated supine trauma patient starts to vomit, it is safer to tip the casualty head down and Figure 2.
