Overview

Multimodal monitoring is of vital importance in neurointensive care. In recent years, multimodal monitoring has gradually incorporated also the measurement of tissue oxygen in the brain tissue (PbrO₂). Measurement of (PbrO₂) provides continuous quantitative data which contributes to the correct management of treatment and important prognostic and pathophysiological data for the detection of secondary brain injuries. Even though the PbrO₂ value for hypoxia has not yet been unequivocally determined, there is apparently a direct link between low values of PbrO₂ and higher morbidity and mortality. The article describes two cases of patients with severe craniocerebral injury and subarachnoidal bleeding where measurement of PbrO₂ was applied. In the first patient, over-threshold values of PbrO₂ were obtained after two hours of targeted treatment. In the second patient, the value of PbrO₂ was higher than 15 mmHg for the whole period of measurement.

Key words:
brain tissue oxygenation – multimodal monitoring – craniocerebral injury – subarachnoidal bleeding
