What is The Baseline Diameter of the Inferior Vena Cava Measured by Sonography Increases With Age in Normovolemic Children about?

## Objectives: To evaluate normative sonographic measurements of the inferior vena cava (ivc) diameter in healthy pediatric patients. ## Methods: We performed a prospective observational study of a convenience sample of healthy patients between the ages of 0 and 22 years presenting to a pediatric emergency department. exclusion criteria included abnormal vital signs, pregnancy, or illnesses thought to influence volume status. during quiet respiration, the maximum and minimum ivc diameters were measured in the sagittal plane distal to the hepatic vein-ivc junction. as second measurements, the maximum diameters of the ivc and aorta were measured in the transverse plane distal to the insertion of the left renal vein into the ivc. ## Results: From february 2013 through april 2014, 63 children (51% female; mean age, 11 years) were enrolled. there were 20 children in each age group of 2 to 7, 7 to 12, and 12 to 22 years. the correlations between ivc and aortic diameters as a function of age were calculated using the spearman rank correlation coefficient. the correlation coefficients were all statistically significant (p < .001): sagittal maximum ivc diameter (0.81), sagittal minimum ivc
