Title: Impact of intracranial pressure measurement on survival in patients with severe traumatic brain injury
Author: S. Krbila, I. Waczulikova, V. Sobona, R. Zahorec

Abstract:  Objective: The aim of the study was to assess (i) a group of patients with established intracranial pressure (ICP) sensor in severe brain injuries scoring 3 points of Glasgow Coma Scale, (ii) mortality and survival of the patients within periods of 7, 30, 180 and 270 days; and (iii) predictive value of intracranial pressure and cerebral perfusion pressure for short and long-term survival of patients with traumatic brain injury.
Material and methods: The group consisted of 61 patients with trauma brain injury scoring 3 points of Glasgow Coma Scale, continuously monitored for intracranial pressure cerebral perfusion pressure at the Intensive Care Unit setting in Nové Zámky. Follow-up period was between 7 and 270 days. Measured values and other recorded data were analysed using methods of descriptive and inferential statistics.
Results: ICP values below 20 mmHg were associated with a significantly lower risk of death of an individual patient at particular time. Accordingly, cerebral perfusion pressure values above 70 mmHg during 0-2 days were associated with a significantly higher long-term survival. Overall mortality rates within 30 days showed no peaks on survival curves. In the periods of 0-7 days, within 30 days, and between 30 and 180 days we recorded 24, 51 and 2 deaths, respectively. In the period between 180 and 270 days, mortality was zero.
Conclusion: The survival of trauma brain injury patients depends on the speed and quality of pre-hospital care and adequate follow-up treatment at specialized intensive care units. High levels of intracranial pressure and low cerebral perfusion pressure values in the early period after brain injury are closely related to mortality of patients within 30 days. Intracranial pressure monitoring may help to avoid problems and allow intervention before they become life-threatening (Tab. 4, Fig. 4, Ref. 23).
