The Incidence and Importance of Intracranial Hypertension in Head-Injured Patients
The incidence and significance of intracranial hypertension in head injury has been a controversial issue. DANDY (6) among others believed that brain swelling and increased intracranial pressure (ICP) were the rule and were the most common causes of death in head-injured patients. In contrast, BROWDER and MEYERS (3), who measured lumbar subarachnoid pressure several times in the same patient, observed marked intracranial hypertension infrequently; and many patients who died did not have increased ICP any time during the course of their illness. Although these contradictory observations were made more than 40 years ago, and ICP has been measured directly and continuously in a large number of head-injured patients in the past decade, there is still disagreement among investigators on the frequency of intracranial hypertension and its contribution to morbidity and mortality.
