The relationship between initial intracranial pressure and the findings of the first computed tomography scan on admission was assessed in 100 consecutive moderate-to-severe head injury patients using a method of multiple regression analysis. Intracranial pressure was measured through a slender subarachnoid catheter with a transducer. Thirty-nine checkpoints of computed tomography findings, including a shift of midline structure, the status of ventricles or cisterns, and the amount of subarachnoid hemorrhage, were investigated. The results were as follows: (1) The computed tomography findings that contributed to estimating intracranial pressure were the appearance of cisterns, the size of a subdural hematoma (number of slices), ventricular size, status of subarachnoid hemorrhage, status of cerebral contusion, magnitude of midline shift, and ventricular index, in that order. (2) Approximately 80% of predicted cases of intracranial pressure were included within the range of measured intracranial pressure +/- 10 mmHg. When the predicted intracranial pressure was less than 30 mmHg, the discrepancy between both intracranial pressures was small. It is concluded that an equation using several computed tomography findings gives a reasonably accurate intracranial pressure for the initial stage of severe head injury.
