Monitoring of Adequate Course of General Anesthesia (MoDA)
A Comparison of Efficacy of Clinical Parameters With Auditory Evoked Potentials in Monitoring of Adequate Course of General Anesthesia
Clinical monitoring is the most common method of adjustment of the appropriate level of general anesthesia. However, the episodes of intraoperative awareness are still reported, suggesting that clinical observations may not be sufficient in some cases. The objective of the study was to compare the efficacy of clinical and instrumental neuromonitoring with auditory evoked potentials in intraoperative analysis of the proper level of general anesthesia.
The patients scheduled for elective surgery were included into the study, and randomly divided into two groups. Patients in the first group (TIVA group) underwent intravenous, in the second group (VA group) underwent volatile anesthesia. The adequacy of anesthesia was analyzed with standard clinical parameters. All the participants were instrumentally monitored with AAI index. After the anesthesia patients received a questionnaire with the questions regarding possible intraoperative awareness.
