[Monitoring of analgesia and amnesia during the general anesthesia in surgeries made on the lungs]
Abstract:
Somatosensorially evoked and auditorially evoked potentials (SSEP and AEP) were evaluated in 75 patients in different stages of general anesthesia during surgical procedures made on the lungs. N19-P23 latent increases of SSEP denoted an adequate level of analgesia. The AEP evaluation is recommended for monitoring the amnesia status during general anesthesia. N1 depression, long-latent N2 and P300 as well as disappearance of AEP and intracerebral asymmetry inversion with predominance of the bioelectric activity in the right cerebral hemisphere are regarded as objective signs of amnesia induction.
