IntroductionThere is variability in clinical practice regarding the number of radiographic views required to accurately determine umbilical venous catheter (UVC) tip position. Some units prefer performing a single anteroposterior (AP) view and others do both AP and lateral views. The aim of this study was to compare the need for one versus two radiographical views to accurately determine UVC tip position.MethodsRadiographs of 382 infants (all gestations) from two level six neonatal units were included in the study. Patients with congenital anomalies and those who had adjustment of UVC position between AP and lateral films being performed were excluded. Six clinicians reviewed anonymized AP only images and documented UVC tip position. Subsequently, they reviewed both AP and lateral views and again documented the UVC tip position. Results were compared to the expert consensus which was taken from the consensus of two paediatric radiologists.ResultsThe study population had a mean gestational age of 32.8 weeks and birth weight of 2190 g, with 58% males. The UVC tip positions were accurately determined 76% times by the AP view alone and 82% times by using both the AP and lateral views (P < 0.001). The low placed UVC tip position which is the most inappropriate for use was more accurately determined by two images (78% times) rather than single image (70% times) (P < 0.001).ConclusionsUtilising both AP and lateral views was superior in accurately determining UVC tip position to AP view alone.
