Perioperative Management of Intracranial Catastrophes

Abstract

The management and evaluation of neurosurgical intracranial catastrophes require a multidisciplinary approach to optimize outcome. Intracranial pathology must be rapidly evaluated. Clinically, the patient's mental status, the degree and extent of focal neurologic deficits, and the dynamic nature of any changes in clinical status are assessed. The CT scan is invaluable for diagnosing and monitoring the progress and extent of intracranial pathology. Medical therapy for the control of intracranial hypertension must be undertaken simultaneously. This begins with provision of an adequate, protected airway and support of cardiopulmonary function. Specific measures to control intracranial hypertension include hyperventilation, osmotherapy, CSF removal, seizure control, autonomic control, sedation (primarily thiopental), muscle relaxation, mild hypothermia, and, if indicated, steroids. The goal of intraoperative management is physiologic support of systemic and cerebral hemodynamics. There should be a smooth transition from the discovery of the patient in extremis through the period of medical stabilization, operative intervention, and ultimate delivery of the patient to the intensive care facility for extended treatment.
