The purpose of the study. Optimization of anesthesia by using the low-opioid anesthesia technique for thoracoplasty in children.
Materials and methods. Analyzed the course of anesthesia in 48 patients aged 3 to 14 years, operations for pectus excavatum in children. The distribution of patients into groups was carried out depending on the technique of anesthesia. Group 1 (main) consisted of 25 children who underwent general anesthesia using low doses of fentanyl, sevoflurane and propofol. group 2 (control) - 23 children who underwent general anesthesia with fentanyl and propofol. Echocardiography was used to determine hemodynamic parameters. The dynamics of changes in the level of cortisol in the blood and the concentration of catecholamines (adrenaline, norepinephrine, dopamine) in the blood was studied.
Results. In children of the first group, during the introductory period of anesthesia, there was a decrease in CI, an increase in heart rate and UPS. Stroke index (SI), mean arterial pressure (MAP),
cardiac index (CI) changed insignificantly compared to the previous stage of the study. In the children of the second group in the most traumatic stages of the operation, there was an increase in SI, HR, and AI. In the most traumatic stages of the operation and after the operation in children of the first group, there was a tendency to increase cortisol, in the second group of patients, an increase in cortisol was noted.
