Filter by:Awake craniotomy require a cooperative patient during resection neurosurgery phase. Anesthesiologist should guarantee analgesia, sedation, nausea and vomiting prevention, while maintaining normal vital parameters. Neurosurgeon could be help by Intraoperative electrocorticography to maximise lesion resection and avoiding neurologic sequelae. Propofol and remifentanyl have been largely used. Dexmedetomidine represents an alternative. However little is known about the role of dexmedetomidine on Intraoperative electrocorticography.
General anesthesia interferes with the whole cerebral cortex at different levels. The goal was to investigate the impact of general anesthesia on different regions of the cerebral cortex by recording the brain's electrophysiological activity using QEEG and BIS during general anesthesia for 40 patients undergoing orthopedic surgeries under general anesthesia to see whether our hypothesis, that there is a topographically-dependent impact of general anesthesia on different regions of the cerebral cortex, is valid or not. The patients were randomly divided into 2 groups of 20 patients to compare the effect on the brain function monitoring (QEEG vs BIS) of the intravenous anesthesia (propofol) with the halogenated anesthesia (sevoflurane). And finally, we compared the two brain function monitoring techniques, BIS and QEEG.
Patients with COPD have lower capability of activating their muscles. At the cortical level, force production is not only controlled by contralateral primary motor cortex but also by ipsilateral motor cortex. The aim of this study is to determine whether ipsilateral areas are functionally impaired in COPD.
