Aim: In this study, we aimed to evaluate the relationship of inferior vena cava (IVC) respiratory variation with hypernatremia due to fluid response, and to evaluate its applicability in determining SNa levels in these patients. Material and Methods: Geriatric patients with dehydration and hypernatremia were included in the study. In the inferior vena cava (IVC) measurement, the diameter of the IVC was measured for each patient by different emergency physicians using experienced and trained sonography. This prospective, cross-sectional and observational study was conducted as a double centre study from January to July 2020. Results: The evaluation was performed on 103 patients. Of the 103 dehydrated patients included in the study, 78 (75.7%) had mild hypernatremia (Serum Sodium (SNa)145-154 mEq/L), and 25 (24.3%) patients had severe hypernatremia (SNa>155 mEq/L). When patients with hypernatremia were divided into two groups as mild and severe, the diagnostic efficiency of the VCI diameter, IVCCI parameters and the ROC curve and AUC, cut-off, sensitivity and specificity were discriminately analyzed to guide the patient's condition in the patient follow-up. For the VCI diameter parameter, the AUC, cut-off, sensitivity and specificity were 0.893 %, 14.7%, 65.2% and 95.2%, respectively. IVCCI AUC, cut-off, sensitivity, and specificity were 0.756, 56.19, 73.9% and 70%, respectively. Discussion: IVC and IVCCI can be used to identify patients with dehydration-induced hypernatremia and determine disease severity, and moreover, they can be used as a useful tool in the assessment of adequate fluid volume replacement in the follow-up of these patients.
