Abstract
The aim of this report is to present first experience in comparing the cour se of brain tissue oxygen pressure values (PtiO(2)) to changes in jugular v ein oxygen saturation (SjvO(2)), intracranial pressure (ICP), and cerebral perfusion pressure (CPP) after severe brain injury. PtiO(2) monitoring was done using a polarographic Clark type microcatheter (LICOX pO(2) probe) (GM S, Kiel, Germany) with a diameter of 0.5 mm and a sensitive area 7.9 mm lon g inserted in a right frontal position. The microcatheter was connected to a LICOX pO(2) device. A fiber-optic catheter was used to measure SjvO(2) an d placed into the right internal jugular vein. The ICP monitoring was perfo rmed with a fiber-optic intraparenchymal device (Camino Laboratories, San D iego, Calif.) inserted in a left frontal position. Consistent correlations could be noticed between reduced PtiO(2) and higher ICP and lower CPP level s. However, the absolute value of a single SjvO(2) data point seemed to be less relevant diagnostically than its trend over a period of time. Owing to their experience, the authors suppose that PtiO(2) monitoring will be a ve ry important and reliable tool in the treatment of brain injury in the futu re, especially in its correlation to ICP and CPP.
