Intracranial Pressure and SvjO2

摘要: Intracranial pressure monitoring gives insight into pathophysiological derangement of intracerebral hemodynamics. It may be used to direct and titrate therapy targeted towards optimizing cerebral perfusion oxygenation, by manipulation water blood content the intracranial cavity. Noninvasive methods are increasingly investigated but suffer challenges in accuracy pragmatic use. The various invasive approaches include ventricular system brain, which remains gold standard. Intraparenchymal a range fiberoptic piezoelectric transducers. Combination devices allow brain oxygen tension or compliance monitoring. Limitations revolve around infection risk fluid channel transduction, as well drift problems parenchymal devices. Jugular bulb saturation (SvjO2) cranial venous outflow combination with Fick principle provides an estimate adequacy meet metabolic demand. With intermittent sampling continuous catheter measurement techniques, it can also provide jugular estimates arteriovenous difference lactate. Its limitations reside its averaging cortical supply versus demand, limits sensitivity regional problems.
