Tracking brain states under general anesthesia by using global coherence analysis.
Time and frequency domain analyses of scalp EEG recordings are widely used to track changes in brain states under general anesthesia. Although these analyses have suggested that different spatial patterns are associated with changes in the state of general anesthesia, the extent to which these patterns are spatially coordinated has not been systematically characterized. Global coherence, the ra...
متن کاملAwareness under general anesthesia.
General anesthesia aims to eliminate patients' awareness of excruciating pain during surgery. Nevertheless, rare occurrences of patient awareness continue because the problem is not yet completely preventable. One study puts the incidence of awareness at 0.18% for patients receiving muscle relaxants and at 0.10% for patients not given relaxant drugs. Awareness experiences frighten patients and ...
متن کاملAwareness under general anesthesia.
BACKGROUND Awareness while under general anesthesia, and the later recall of what happened during surgery, can be experienced by patients as horrific events that leave lasting mental trauma behind. Patients may have both auditory and tactile perception, potentially accompanied by feelings of helplessness, inability to move, pain, and panic ranging to an acute fear of death. For some patients, t...
متن کاملAnisocoria under general anesthesia with Propofol
Anisocoria during anesthesia is very rare, but may indicate life-threatening neurologic injuries and create tremendous condition. A 23-year-old male patient was anesthetized with fentanyl and propofol. Thirty minutes after inducing anesthesia, unilateral mydriasis was detected. The duration of surgery was shortened for prompt evaluation of the pupils. At the end of the operation neither vision ...
متن کاملBrain Stimulation and General Anesthesia
006 preliminary data points to a possible effect in acute pain [8]. Other types of stimulation, such as transcranial Pulsed Current Stimulation (tPCS), are also under experimental and clinical evaluation. None of the current techniques use the high energy previously related [1]. The correct parameters of stimulation to promote anesthesia, as well as the safety and efficacy of the association of...
