Umbilical venous catheters (UVCs) and umbilical arterial catheters (UACs) are marked at intervals indicating the distance in centimetres (cm) from the tip. When inserting umbilical catheters, clinicians estimate the depth to which they should insert them using birth weight1 or shoulder, umbilicus length,2 and secure them at this depth as indicated on the catheter. Complications occur more frequently with umbilical catheters when the tip is incorrectly positioned.3 ,4

We suspected that the marks on UVCs and UACs might not accurately indicate the …
