ABSTRACT

BACKGROUND: Fluid administration to increase stroke volume index (SVi) is a cornerstone of haemodynamic resuscitation. We assessed the accuracy of SVi variation during a calibrated abdominal compression manoeuvre (ΔSVi-CAC) to predict fluid responsiveness in children. METHODS: Patients younger than 8 yr with acute circulatory failure, regardless of their ventilation status, were selected. SVi, calculated as the average of five velocity-time integrals multiplied by the left ventricular outflow tract surface area, was recorded at four different steps: baseline, after an abdominal compression with a calibrated pressure of 25 mm Hg, after return to baseline, and then after a volume expansion (VE) of 10 ml kg-1 lactated Ringer solution over 10 min. Patients were classified as responders if SVi variation after volume expansion (ΔSVi-VE) increased by at least 15%. RESULTS: The 39 children included had a median [inter-quartile range (IQR)] age of 9 [5-31] months. Twenty patients were fluid responders and 19 were non-responders. ΔSVi-CAC correlated with ΔSVi-VE (r=0.829; P<0.001). The area under the receiver operating characteristic curve (ROCAUC) was 0.94 [95% confidence interval (CI), 0.85-0.99]. The best threshold for ΔSVi-CAC was 11% with a specificity of 95% [95% CI, 84-100] and a sensitivity of 75% [95% CI, 55-95]. ROCAUC of respiratory variation of IVC diameter (ΔIVC) was 0.53 [95% CI, 0.32-0.72]. CONCLUSION: ΔSVi-CAC during abdominal compression was a reliable method to predict fluid responsiveness in children with acute circulatory failure regardless of their ventilation status.

ABSTRACT

OBJECTIVE: To compare management of injured children in an adult trauma center (TC) with competencies in pediatric trauma care (2005-2007) and in a pediatric-only trauma center (2010-2012). STUDY DESIGN: A before-after retrospective study. PATIENTS AND METHODS: Fifty-nine children between 1 and 15 years of age admitted to the adult TC (2005-2007) were compared to 56 children admitted to the pediatric TC (2010-2012). Epidemiological data, severity scores, early outcome, and care duration in trauma resuscitation before whole-body CT were collected and compared between the two periods. RESULTS: This study found no significant differences between the two periods in terms of care duration before the whole-body CT scan (28 min [18-40] vs 26.5 min [21-36], P=0.89) and early mortality (eight children [13.5%] vs ten children [17.8%], P=0.35). CONCLUSION: With no differences in early management of injured children demonstrated, this study validates the organization within our pediatric trauma center. The effectiveness of management of children between 1 and 15 years of age with severe trauma seems to be similar in the two contexts.
