Abstract
In recent years there has been an increase in the number of victims of road traffic accidents and emergencies that require the surgical treatment with reliable and safe anesthesia. The routine procedure with mechanically controlled concentration of inhalation anesthetic was compared with automated control of inhalation anesthetic and oxygen concentrations on the exhale (Et-control) during low-flow inhalation anesthesia (LFA). A prospective, randomized study included 80 patients who underwent surgery for the pathology of the spine and the spinal cord of varying severity, extent and localization. The study objective was to compare LFA course and sevoflurane consumption under mechanical and automated control of the anesthetic concentration in exhaled gas mixture during traumatic interventions on vertebra. The study showed that LFA with the automated control of exhaled anesthetic and oxygen concentrations 2 times lowers inhalation anesthetic consumption and considerably lowers the cost of anesthesia. This technique in high-risk operations, including neurosurgery, allows controlled anesthesia with optimal concentration of anesthetic and minimal hemodynamic response of the patient, while maintaining the quality of the general anesthesia.
