Near Infrared Spectroscopy for Detection of Cerebral Desaturation After Positioning for Neurosurgical Procedures

Czechia100 participantsStarted 2017-04-01

Plain-language summary

The occurrence of postoperative cognitive dysfunction (POCD) might be related to intraoperative cerebral desaturation. Positioning for neurosurgical procedures are associated with head rotation, elevation, flexion or extention that may affect blood brain inflow and outflow. Anatomical variations of Willis circle could affect the cerebral blood flow in extreme head position with the development of cerebral ischemia or functional changes of brain. Investigators suppose that detection of cerebral tissue desaturation and its prompt correction could modify the occurence of POCD after these procedures.
