Review Practice Guideline GuidelineThe Brain Trauma Foundation. The American Association of Neurological Surgeons. The Joint Section on Neurotrauma and Critical Care. Pupillary diameter and light reflex.
The pupillary diameter and the pupilloconstrictor light reflex are the two parameters that have been studied extensively in relation to prognosis. Accurate measurement of pupil diameter or the constrictor response or the duration of the response has not been performed in studies on traumatic brain-injured individuals--for lack of a standardized measuring procedure. The following is recommended: 1. ⋯ Hypotension and hypoxia should be corrected before assessing pupils for prognosis. 7. Direct orbital trauma should be excluded. 8. Pupils should be reassessed after surgical evacuation of intracranial hematomas.

Review Practice Guideline GuidelineThe Brain Trauma Foundation. The American Association of Neurological Surgeons. The Joint Section on Neurotrauma and Critical Care. Recommendations for intracranial pressure monitoring technology.
In patients who require ICP monitoring, a ventricular catheter connected to an external strain gauge transducer or catheter tip pressure transducer device is the most accurate reliable method of monitoring ICP and enables therapeutic CSF drainage. Clinically significant infections or hemorrhage associated with ICP devices causing patient morbidity are rare and should not deter the decision to monitor ICP. ⋯ These devices are advantageous when ventricular ICP is not obtained or if there is obstruction in the fluid couple. Subarachnoid or subdural fluid coupled devices and epidural ICP devices are currently less accurate.

Of utmost importance in the practice of neurological critical care is the treatment of cerebral edema, when possible, and the control of life-threatening seizures. In this regard, severe traumatic head injury and refractory status epilepticus are useful clinical therapeutic paradigms. Evidence-based treatment established for these conditions has, by necessity, a wider application to other much less frequent causes of coma and acute neurological illness managed in the intensive therapy unit. Therefore, this review of pediatric neurocritical care literature in 1999 highlights central clinical reports of the medical management of severe traumatic brain injury, the benzodiazepines used in the treatment of status epilepticus, and the emerging or recently appreciated encephalopathies occurring in children.

ReviewThe early assessment and intensive care unit management of patients with severe traumatic brain and spinal cord injuries.
The assessment and management of neurotrauma have progressed significantly over the past several years. Improved understanding of the physiology of injured neural tissue and advances in technology have refined the approach to the care of patients suffering neurologic injury. ⋯ The ongoing evolution of critical care also has had a significant impact on the care of patients suffering from neurotrauma. This article reviews some current issues related to the diagnosis and management of traumatic brain injury and spinal cord injury as we head into the next millennium.

Review Practice Guideline GuidelineThe Brain Trauma Foundation. The American Association of Neurological Surgeons. The Joint Section on Neurotrauma and Critical Care. Use of barbiturates in the control of intracranial hypertension.
High-dose barbiturate therapy is efficacious in lowering ICP and decreasing mortality in the setting of uncontrollable ICP refractory to all other conventional medical and surgical ICP-lowering treatments. Utilization of barbiturates for the prophylactic treatment of ICP is not indicated. The potential complications attendant on this form of therapy mandate that its use be limited to critical care providers and that appropriate systemic monitoring be undertaken to avoid or treat any hemodynamic instability. When barbiturate coma is utilized, consideration should also be given to monitoring arteriovenous oxygen saturation as some patients treated in this fashion may develop oligemic cerebral hypoxia.
