Raised intracranial pressure (ICP) has been consistently associated with poor neurological outcome. Our purpose was to systematically review the literature to estimate the association between ICP values and patterns and short- and long-term vital and neurological outcome. ⋯ Refractory ICP and response to treatment of raised ICP could be better predictors of neurological outcome than absolute ICP values. Limitations in the design of the studies analyzed precluded identification of the role of ICP monitoring in predicting short- and long-term outcomes.

Case Reports
Aminophylline for the treatment of symptomatic bradycardia and asystole secondary to cervical spine injury.
Bradycardia is a common complication of cervical spine damage in the weeks following injury, occurring in up to 100% of patients in some studies. Cardiac arrest and asystole have been reported in as many as 15% of these patients and cardiac events are the main cause of death within the first year. We describe the case of a 25-year-old African-American male involved in a motor vehicle collision who suffered C6-C7 subluxation. ⋯ There is limited evidence for the use of methylxanthines in the treatment of bradycardia associated with spinal cord injury. In patients with recurrent asystolic events or symptomatic bradycardia the use of these agents should be considered.

A 38-year-old man with severe head trauma complicated by paroxysmal severe intracranial pressure elevation associated with tachypnea, tachycardia, diaphoresis, and extensor posturing was diagnosed as suffering from paroxysmal autonomic instability with dystonia (PAID). These events were unresponsive to standard medical therapy, which included morphine, fentanyl, labetalol, lorazepam, metoprolol, and clonidine. ⋯ Dexmedetomidine may be a novel pharmacologic agent to aid in abrogating PAID.

Randomized Controlled Trial
Continuous low dose diclofenac sodium infusion to control fever in neurosurgical critical care.
Aim of this randomized prospective clinical trial is to compare two methods of antipyretics and evaluate their efficacy in controlling fever during the acute phase of brain damage. ⋯ Low dose DCF infusion is a potential useful strategy for a successful control temperature better than intermittent NSAIDs dosing, minimizing potentially brain-damaging effects of fever.

No experimental data has been published on the long-term effects of decompressive craniotomy in hypertensive rats with space-occupying cerebral infarction. The aim of the present study was to investigate the efficacy of decompressive craniectomy in a middle cerebral artery occlusion (MCAO) model of hypertensive rats in a prolonged period. ⋯ Although the early craniectomy is more effective than delayed craniectomy in improving short-term outcome, the latter has the similar beneficial effects as early craniectomy on long-term outcome in hypertensive rats with space-occupying cerebral infarction.
