| Description | Tissue oxymetry has been recently recognized as a useful tool in early detection of ischemic events in patients after subarachnoid hemorrhagie (SAH). During the years 2006 – 2010 we used tissue oxymetry monitoring in more than 70 patients after the aneurysmal SAH. We used the Licox system. We applied the probe to the region of the vessel with aneurysm. PbtO2 in the groups HH1,2, (n = 28), HH3 (n = 17) and HH4,5 (n = 30) are similar untill 7th day after SAH (around 22 mmHg), than around 11th day the values in group HH1,2 increase to about 32 mmHg, values in the group HH 3 continued at same levels while the values in the group HH 4,5 decreased to approximately 8 mm Hg. Good outcome is associated with PbtO2 values which are higher then 20 torr. All patients HH 1,2 had a favorable outcome and no signs of clinical vasospasm. Response of PbtO2 values to FiO2 manipulation may differ between patients with and without vasospasm. Good outcome is associated with PbtO2 values which are higher than 20 mmHg. Patients HH 1,2 had all good outcome and did not benefit from this type of monitoring. Our current observations show that the brain tissue oximetry might be advantageous in the early detection of ischaemic changes in severe SAH cases and is complimentary to TCD. |
