Abstract
The purpose of the study is to determine the significance of variability index of the heart stroke volume in assessing the volemic status of patients during carotid endarterectomy.
Materials and methods. The study included 60 patients who underwent carotid endarterectomy. The average age of patients is 68 ± 7.4 years. The operation was performed under general anesthesia with mechanical ventilation. Cardiorespiratory interaction was studied. The parameters of the state of central hemodynamics were recorded before and after the functional hemodynamic test with the patient’s legs raised. The patients were divided into 3 groups according to the change in the stroke volume of the heart on the test results.
Results. The 1st group included 11 patients (18%), they have a volemia deficiency in combination with a decrease in myocardial contractility, 18 patients (30%) of the 2nd group suffered deficiency of volemia, and 31 patients (52%) having satisfactory hemodynamics were included into the 3rd group. The results of the test with raising of the legs demonstrated that the changes in the SVV indicator corresponded completely to the changes in stroke volume. It was revealed that, irrespectively of the initial state of hemodynamics, the index of variability of the heart stroke volume correctly reflected the state of the volemic status of patients during carotid endarterectomy.
Findings. The rate of variability of heart stroke volume allows to evaluate the effectiveness of the infusion therapy and to control the volemic load during the carotid endarterectomy operation.
