Anesthesia monitoring tips and devices
Paulius Čerkauskas, Algirdas Bieliauskas
AIM: To review scientific and clinical researches on monitoring the depth of anesthesia.
Materials and methods: Systematic literature review was done.
Results: Comparing usual and actual physiological changes during induction of anesthesia helps to predict patient’s anesthesia quality and optimization anesthetic dosage. Several different devices are used in clinical practice to monitor anesthesia: Electromyography (EMG), compressed spectral array (CSA), Lower Esophageal Contractility (LOC), Entropy, Bispectral Index (BIS), Electroencephalogram (EEG), Heart rate variability (HRV). These devices differ by algorithms and mechanisms, but still are advantageous in clinical practice of anesthesiologist.
Conclusions: There are many competitive devices, which can be used to monitor efficacy of anesthesia, however to determine the most accurate device further clinical trials must be performed.
Key words: Depth of anesthesia monitoring, Anesthetics, Control of anesthesia.
