Abstract
PURPOSE: This study evaluates the capacity of ultrasonography as a diagnostic method to confirm the proper positioning of central venous catheter (CVC) when compared to the current gold standard, chest radiography (CR). METHODS: A prospective study was performed including children from 0 to 14 incomplete years, who underwent CVC placement between March and May 2018 at a teaching hospital in Brazil. A four-chamber view of the heart was performed with ultrasound during a rapid injection of saline solution to identify hyperechoic images and confirm the central position of the catheter. After that, a CR was performed. The diagnostic quality of ultrasound was evaluated based on accuracy, sensitivity, specificity, positive and negative predictive values. RESULTS: A total of 21 patients were analyzed. The mean age was 3.95 ± 4.01 years. The preferred puncture site was the right internal jugular vein (71.4%). Ultrasound accuracy to detect CVC positioning was 81%. Sensitivity, specificity and positive and negative predictive values were 33%, 100%, 100% and 79%, respectively. CONCLUSION: Ultrasound is a reliable method for detection of CVC positioning. Even so, with the four-chamber cardiac view, this method is unable to identify catheters inside heart chambers, therefore, needing to confirm the positioning with CR.
