Despite the existence of commercially available devices that monitor anesthetic depth
through the patient s electrical brain activity (EEG), reliability and robustness issues stop them from becoming part of routine surgical practice.
defined using multiple noxious stimuli during isoflurane/oxygen anesthesia.
Among the chapter topics are the relevance of sleep neurobiology for cognitive neuroscience and anesthesiology, the neurobiology of consciousness, memory formation during general anesthesia, monitoring anesthetic depth
, and three chapters on the psychological, philosophical, and medicolegal consequences of intraoperative awareness.
Parameters evaluated during anesthesia included heart rate, respiratory rate, anesthetic depth
, and electrocardiogram readings.
61) Any time paralytic drugs are used in surgery, the necessity of adequately maintained anesthesia is that much more important, as the drugs restrict the patient's ability to verbally communicate sensation, or physically respond to assessments of anesthetic depth
Those patients identified as at risk should be informed and anesthetic depth
should be monitored using multiple modalities.
Dreaming during anesthesia and anesthetic depth
in elective surgery patients: a prospective cohort study.
In the OR it appears that the PSA 4000 may serve as a reliable indicator of anesthetic depth
The study was conducted at the University of Florida in Gainesville and Aspect Medical Systems' BIS(TM) monitoring technology was used to measure anesthetic depth
Muscle tone of the neck is reported as a useful indicator of anesthetic depth
According to Sami Ervio, Managing Director of Datex-Ohmeda's European Sales Companies, "The addition of BIS reflects our commitment to offering our customers the best and most complete range of clinical parameters to address all of the components of anesthetic depth
as part of the System 5 solution for anaesthesia.
In sequence, we increased FiO2 to 100 percent, increased PaCO2, increased mean arterial pressure, increased pump flow, increased anesthetic depth
, administered nitroglycerin, and transfused packed red cells if hematocrit was less than 20 percent.
