ABSTRACT
Introduction: Ultrasound of inferior vena cava and its indexes have been related to central venous pressure in adults. There are no studies in Cuba that relate these parameters to each other in a population of critical pediatric patients.Objective: To correlate the values of the central venous pressure with the sonographic indices of inferior vena cava in critical pediatric patients.
Methods: An observational, prospective, case-series study was conducted with 50 patients admitted to the Pediatric Intensive Care Unit of Octavio de la Concepción de la Pedraja Provincial Pediatric Hospital, from May 2017 to May 2018. These patients had spontaneous breathing or mechanical ventilation. 22 demographic, hemodynamic and ultrasound variables were analyzed. Pearson's coefficient was used to express correlations. An ROC curve was created to determine the extreme points of central venous pressure through ultrasound measurements of the inferior vena cava.
Results: The collapsibility index of inferior vena cava showed strong negative correlations with the central venous pressure r= -0.686. Cut-off points of 25.9% and 11.1% were defined to estimate the central venous pressure ≥ 12 cm H2O, with an area under the 0.94 and 0.89 curve for each ultrasound index.
Conclusions: A strong correlation was identified between the central venous pressure and inferior vena cava indices obtained by ultrasound in critical pediatric patients. This study is very useful as advice on fluid response therapy.
