Abstract
Seventy-six severely head-injured patients, 67% of whom had Glasgow Coma scores of five or less on admission, were managed according to an intensive treatment regime which included controlled hyperventilation (under full muscular paralysis), high-dose steroids, dehydrating agents, diuretics and hypnotics (Althesin and thiopentone). Intracranial pressure (ICP) was measured throughout the period of controlled ventilation. Treatment was directed to keeping the mean ICP below 25-30 mmHg and to the prevention of increases in ICP during chest physiotherapy and other noxious stimulation. Six months after injury 46% of patients had died and 4% were vegetative survivors, whilst 43% had made a good recovery or were only moderately disabled. Features associated with worse than average prognosis were: low coma score, pupillary abnormalities, respiratory dysrhythmia and ICP greater than 30 mmHg. Spontaneous hyperventilation was a relatively good initial feature. These results support the employment of intensive care in severely head-injured patients, particularly those with diffuse brain injury.
