PURPOSE: To determine normative data for the inferior vena cava (VCI) diameter in euvolemic children and its correlation with different somatic parameters in a pediatric population at one center in Europe. MATERIALS AND METHODS: This prospective observational study enrolled healthy children aged 4 weeks to 18y that visited our outpatient clinic. Weight, height, body surface area, and age were recorded. The children were grouped according to weight, as follows (80 children/group): < 10 kg, 10-19.9 kg, 20-29.9 kg, 30-59.9 kg, and 60-90 kg. Children were placed in a supine position and, during quiet respiration, the maximum and minimum VCI diameters were measured with M-mode ultrasonography. The collapsibility index (CI) was also automatically calculated for each subject: CI = [VCI maximum (expiratory) diameter - VCI minimum (inspiratory) diameter]/VCI maximum (expiratory) diameter. RESULTS: From May 2016 through November 2018 we retrieved data for 415 children that underwent VCI diameter evaluations. 400 children were included (mean age: 7.8y ± 5.8, mean weight: 32 kg ± 24.4, 46 % girls). The VCImax and the VCImin were significantly correlated with age (r = 0.867, p < 0.001, r = 0.797, p < 0.001), height (r = 0.840, p < 0.001, r = 0.772, p < 0.001), weight (r = 0.858, p < 0.001, r = 0.809, p < 0.001), and BSA (r = 0.878, p < 0.001, r = 0.817, p < 0.001). Correlations between the CI and age, weight, height, and BSA were not statistically significant. CONCLUSION: This prospective study provided reference values for sonographic measurements of VCI diameters in euvolemic children and might greatly assist in assessing fluid status in sick children.

OBJECTIVES: To determine if there is a difference between regional citrate and global heparinized anticoagulation on circuit lifetimes during continuous venovenous hemodialysis in children. DESIGN: Prospective "cross-over" trial. SETTING: PICU, Department of Pediatrics, University Hospital Ostrava. PATIENTS: Children 0-18 years old. INTERVENTIONS: From 2009 to 2014, 63 eligible children (age, 89.24 ± 62.9 mo; weight, 30.37 ± 20.62 kg) received at least 24 hours of continuous venovenous hemodialysis. Each child received four continuous venovenous hemodialysis circuits with anticoagulants in the following order: heparin, citrate, heparin, citrate. Circuit life ended when transmembrane pressure was greater than or equal to 250 mm Hg for more than 60 minutes. MEASUREMENTS AND MAIN RESULTS: The total mean circuit lifetime was 39.75 ± 10.73 hours. Citrate had a significantly longer median circuit lifetime (41.0 hr; CI, 37.6-44.4) than heparin (36.0 hr; CI, 35.4-36.6; p = 0.0001). Mortality was 33.33%. Circuit lifetime was significantly correlated to patient age (r = 0.606), weight (r = 0.763), and blood flow rate (r = 0.697). Transfusion rates (units of red cells per circuit of continuous venovenous hemodialysis) were 0.17 (0.0-1.0) with citrate and 0.36 (0.0-2.0) with heparin (p = 0.002). CONCLUSIONS: We showed in our study that citrate provided significantly longer circuit lifetimes than heparin for continuous venovenous hemodialysis in children. Citrate was superior to heparin for the transfusion requirements. Citrate was feasible and safe in children and infants.
