Hemodynamic Status in Patients Undergoing Surgical Correction of Severe Scoliosis under Different variants of Anesthetic Protection

Abstract

To study the laws of hemodynamic changes in patients undergoing staged surgical correction of severe scoliosis ander with different variants of anesthetic protection. Material and Methods. Non-invasive monitoring of basic parameters of central and peripheral hemodynamics by impedance cardiography was performed in 59 patients with severe scoliosis undergoing surgery under anesthetic protection with different hypnotic components of general anesthesia. Results. It was defined that main factors determining the patient's hemodynamic status during surgical scoliosis correction were the following: intraoperative position, duration of exposure, and intensity of cardiodepressive and vasodilative effects of drugs used for anesthetic protection. The study has shown that inhalation anesthesia with sevoran in comparison with total intravenous anesthesia with propofol is associated with more adverse hydration status of the lungs, which increases the risk of respiratory and pulmonary-cardiac insufficiency. Conclusion. Non-invasive impedance cardiography for the real time assessing the hemodynamic state of patients may appear to be crucial in selection of anesthesia components.
