ABSTRACT
OBJECTIVE: To compare anesthesia quality and sevoflurane consumption during standard and extended intraoperative monitoring. MATERIALS AND METHODS: 74 patients were included in prospective randomized study. Patients had spinal pathology of varying severity, extension and localization. A comparative evaluation of standard and extended (with entropy) monitoring was performed during low-flow inhalation anesthesia with the automated control of the anesthetic concentration and exhaled oxygen fraction (Et-control). RESULTS: Monitoring depth of anesthesia based on entropy enables more accurate dosing of inhaled anesthetics. CONCLUSIONS: The study revealed that the use of entropy monitoring in high-risk surgery alleviates providing the controlled anesthesia with the optimal inhalation anesthetic concentration and minimal hemodynamic reactions of the patient.

Selection of inhalation anaesthetic when low-flow anaesthesia with automated control. A comparative evaluation of low-flow (0,5 l/min) and inhalation anaesthesia with sevoflurane and desfluranom with automated control of the concentration of inhaled anaesthetic on the exhale (Et-control), with the use of advanced monitoring in 76 patients operated on for the pathology of the spine and spinal cord is given. It was found that when using continuous measuring the achievement of the target concentration of the anaesthetic sevoflurane is faster in the group. Total consumption of desflurane was two times higher. Hemodynamic, SPI index were stable at all stages of the operation in both groups.
