The introduction of the MET may put the selection on a more experienced and scientific footing. The final decision maker should be the senior doctor in Guidelines approved by the medical staff committee at charge of the patient’s management. That senior doctor, Frenchay Hospital, Bristol however, will usually want to take cognisance of the opinions and There can be no rules; every patient must be considered wishes of the patient and the relatives and the views of the junior individually and this decision should be reviewed as doctors, family practitioner, the MET if available, and nurses who appropriate—this may be on a weekly, daily, or hourly basis. The decision should be made before it is needed and in many Once the decision not to resuscitate has been made, it patients this will be on admission.

The decision to terminate resuscitative efforts will depend on a number of factors discussed below.

The patient must be examined neurologically before each increment discount estrace 2mg, and the traction force must be reduced immediately if the neurology deteriorates purchase 2 mg estrace with mastercard. Manipulation under general anaesthesia is an alternative method of reduction, but, although complete neurological recovery has been reported after this procedure, there have been adverse effects in some patients and manipulation should 22 Early management and complications—II only be attempted by specialists. Halo traction is a useful alternative to skull calipers, particularly in patients with incomplete tetraplegia, and conversion to a halo brace permits early mobilisation. Skull traction is a satisfactory treatment for unstable injuries of the cervical spine in the early stages, but when the spinal cord lesion is incomplete, early operative fusion may be indicated to prevent further neurological damage. The decision to operate may sometimes be made before the patient is transferred to the spinal injuries unit, and if so the spinal unit Figure 5. Another indication for operation is an open wound, such as that following a gunshot or stab injury. Skull traction is unnecessary for patients with cervical spondylosis who sustain a hyperextension injury with tetraplegia but have no fracture or dislocation. In these circumstances the patient should be nursed with the head in slight flexion but otherwise free from restriction. The thoracic and lumbar spine Most thoracic and lumbar injuries are caused by flexion-rotation forces. Conservative treatment for injuries associated with cord damage is designed to minimise spinal movement, and to support the patient to maintain the correct posture. In practice a pillow under the lumbar spine to preserve normal lordosis is sometimes used. Dislocations of the thoracic and lumbar spine may sometimes be reduced by this Figure 5.
