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. They tend to be very formal affairs with truly known to the patient himself) a strict protocol to be followed. The above guidelines have been in use for the past 16 years and A hospital ethical resuscitation policy should contain the during this period no medical or nursing staff have objected to following guidelines: their use.

Resuscitation should be abandoned after 15 minutes Termination of resuscitation attempts If resuscitation does not result in a relatively early return of spontaneous circulation then one of two options must be considered: ● Termination of further resuscitation efforts ● Support of the circulation by mechanical means, such as cardiac pacing, balloon pumping, or cardiopulmonary bypass. The decision to terminate resuscitative efforts will depend on a number of factors discussed below. Evidence of cerebral damage The environment and access to emergency medical Persistent fixed and dilated pupils, unrelated to previous drug services therapy, are usually, but not invariably, an indication of serious cerebral damage, and consideration should be given to Cardiac arrest occurring in remote sites when access to abandoning resuscitation in the absence of mitigating factors. Generally speaking, if the interval is greater than five minutes then the prognosis is poor unless mitigating factors, such as hypothermia or previous sedative drug intake, are present.

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.
