Severe traumatic brain lesions in Sweden. Part 2: Impact of aggressive neurosurgical intensive care.
During a 6 year period (1977-1982), 425 patients were treated in the Department of Neurosurgery, University Hospital of Lund, for severe traumatic brain lesions (coma greater than 6 hours). From 1983 a more aggressive management protocol was introduced including early recording of intracranial pressure (ICP) and 162 patients were included in the study 1983-1984. A dangerous increase in ICP in spite of adequate surgical treatment and moderately controlled hyperventilation was the incentive for barbiturate coma therapy in selected patients. In the first part of the study overall mortality was 48% whereas 39% of the patients reached good recovery/moderate disability 6 months after injury. During the second part of the study the corresponding figures were 35% and 54%, respectively (in both cases p less than or equal to 0.01). In the group of patients with focal intracranial mass lesions mortality decreased from 59% to 46% (p less than or equal to 0.05) and good recovery/moderate disability increased from 30% to 42% (p less than or equal to 0.05). Improvement in outcome was even more pronounced in patients with no-mass lesions, mortality decreased from 30% to 12% and good recovery/moderate disability increased from 56% to 80% (p less than or equal to 0.05 and p less than or equal to 0.01, respectively). No change occurred in age distribution or in the types of intracranial lesions that could explain these improvements. It is concluded that aggressive neurosurgical intensive care significantly improves outcome in patients with severe traumatic brain lesions.
