Accuracy of chest radiography for positioning of the umbilical venous catheter
Jornal de Pediatria, 2017
Objectives: To evaluate the accuracy of the simultaneous analysis of three radiographic anatomical landmarks-diaphragm, cardiac silhouette, and vertebral bodies-in determining the position of the umbilical venous catheter distal end using echocardiography as a reference standard. Methods: This was a cross-sectional, observational study, with the prospective inclusion of data from all neonates born in a public reference hospital, between April 2012 and September 2013, submitted to umbilical venous catheter insertion as part of their medical care. The position of the catheter distal end, determined by the simultaneous analysis of three radiographic anatomical landmarks, was compared with the anatomical position obtained by echocardiography; sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. Results: Of the 162 newborns assessed by echocardiography, only 44 (27.16%) had the catheter in optimal position, in the thoracic portion of the inferior vena cava or at the junction of the inferior vena cava with the right atrium. The catheters were located in the left atrium and interatrial septum in 54 (33.33%) newborns, in the right atrium in 26 (16.05%), intra-hepatic in 37 (22.84%), and intra-aortic in-one newborn (0.62%). The sensitivity, specificity and accuracy of the radiography to detect the catheter in the target area were 56%, 71%, and 67.28%, respectively.

The use of plain radiographs provides limited information on the placement of peripherally inserted central catheters (PICCs). Moreover, changes in upper extremity positioning cause migration of the catheters in neonates. This study aimed to investigate the use of echocardiography for determining catheter tip position, compared with plain radiographs, in low birthweight (LBW) infants in a tertiary neonatal intensive care unit. Methods: The study examined the placement of 109 catheters in 89 infants born between September 2010 and December 2012. The placement of these catheters was controlled by echocardiography, with the patient's shoulder in adduction and the elbow in flexion. The number of catheter tips, echocardiographically identified within the heart, was expressed as a percentage of the total catheters deemed to be well positioned on plain radiographs. Results: The number of catheter tips that were echocardiographically identified within the heart was significant (25%, p < 0.001). Twenty-three catheters were repositioned to be outside of the heart, without any complications. Conclusion: This study demonstrated the value of echocardiography for identifying the positioning of catheter tips in LBW infants. Echocardiography, coupled with initial plain radiographs, should be the gold standard for assessing PICC tip positions in those infants.

In critically ill neonates, umbilical arterial (UAC) and umbilical venous (UVC) catheters are frequently necessary. Catheter position is usually verified by roentgenography (R) which generates ionizing radiation and requires deleterious patient manipulation. We employed 2-dimensional echocardiography (2-DE) to localize UAC and UVC catheters in 55 neonates (birth weights .65

Systemic hypotension is common in very low birthweight preterm infants but the nature of the precipitating cause may be unclear. Targeted neonatal echocardiography (TnEcho) is being increasingly used to support hemodynamic decisions in the neonatal intensive care unit (NICU), including identifying impairments in the transitional circulation of preterm infants, providing timely re-evaluation after institution of therapies and evaluating the placement of indwelling catheters. We present a case of a preterm infant with systemic hypotension and low cardiac output secondary to a large transatrial shunt induced by a malpositioned umbilical venous catheter. Repositioning of the line led to resolution of the hemodynamic disturbance and clinical instability, highlighting the utility of TnEcho in the NICU.

AimSafe tip placement of umbilical venous catheters (UVCs) in sick neonates is critical in minimising risk. We aimed to demonstrate the utility of clinician‐performed ultrasound (CPU) in identifying UVCs that are placed within small intrahepatic portal vessels or within the heart despite the appearance of being well placed on X‐ray.MethodsThis was a retrospective observational study of preterm and term neonates who had a UVC placed and the position assessed by X‐ray and/or CPU according to the Royal Prince Alfred Hospital level 3 neonatal intensive care unit (NICU) guideline. Cases were identified by exporting the records of all admissions between 1 April 2015 and 30 June 2016 from the NICU's data collection database. Paper‐based medical records, NICU's data collection database records and the ultrasound reporting system were reviewed to determine X‐ray and CPU findings.ResultsA total of 157 neonates had 169 UVCs placed. CPU was performed in 77% (111). In 15 cases (14%), UVC...
Umbilical venous catheter position: evaluation by ultrasound
European Radiology, 2011
Objective Umbilical venous catheter (UVC) insertion is frequently performed in critically ill neonates, with catheter position evaluated by an abdominal radiograph. The position of the catheter can be difficult to assess based on supine film alone. We aimed to determine whether ultrasound enables precise evaluation of the catheter tip position. Methods We prospectively evaluated UVC position in 75 neonates by ultrasound and supine abdominal radiograph. Distance from the catheter tip to the diaphragm was measured for both modalities. Anatomical location of the catheter was recorded for both studies. The Student's t-test was used to compare the means of the differences in catheter position on radiograph and ultrasound. Results In 46 patients there was no difference in the distance between the catheter tip and the diaphragm on ultrasound and radiograph. In 29 babies there was a difference of 1-to-7 mm. Ultrasound identified malposition of the catheter in three cases in which the position of the catheter on the plain film was deemed acceptable. Conclusions Our study suggests that ultrasound is reliable and may replace plain radiograph for the identification of the UVC position, preventing complications from malposition, and reducing exposure to ionizing radiation.

Background Chest radiography after peripherally inserted central catheter insertion in infants is the reference standard method for verifying catheter tip position. The utilisation of ultrasound (US) for catheter placement confirmation in the neonatal and paediatric population has been the focus of many recent studies. Objective In this systematic review we investigated the diagnostic accuracy of US for peripherally inserted central catheter tip confirmation in infants in the neonatal intensive care unit (NICU) Materials and methods We conducted a systematic literature search of multiple databases. The study selection yielded eight articles, all of which had acceptable quality and homogeneity for inclusion in the meta-analysis. Sensitivity and specificity values were reported together with their respective 95% confidence intervals (CI). Results After synthesising the eligible studies, we found that US had a sensitivity of 95.2% (95% CI 91.9-97.4%) and specificity of 71.4% (95% CI 59.4-81.6%) for confirming catheter tip position. Conclusion Analyses indicated that US is an excellent imaging test for localising catheter tip position in the NICU when compared to radiography. Ultrasonography is a sensitive, specific and timely imaging modality for confirming PICC tip position. In cases where US is unable to locate malpositioned PICC tips, a chest or combined chest-abdominal radiograph should be performed.
