The bedside nurse will secure the umbilical catheter to the abdomen by placing a cut piece of. Appropriate placement of the tip is in either a low (元-L4) or high (T6-T10) position. Preparation of a complete UVC insertion kit should occur well in advance of a planned home birth and should be complete and readily available for every home. This lies in the free edge of the falciform ligament and is also continuous with the ligamentum venosum (the remnant of the ductus venosus).Īn umbilical artery catheter (UAC) is passed through either one of the umbilical arteries and descends to the iliac artery before ascending to the aorta. The ideal UVC tip position is outside the heart at the junction of inferior vena cava (IVC) and right atrium (RA) 1, 4, 5, 6, 7. ![]() The umbilical vein closes soon after birth (<7 days) and becomes the round ligament of the liver. The UVC is usually inserted by skilled medical staff at a distance previously calculated using anthropometric measures or formulas and nomograms usually based on birth weight (BW) 2, 3. Misplacement can occur amongst other places, in normal anatomy, at the level of the left portal vein and at the level of the hepatic veins. The correct position of the tip of the UVC is at or close to the inferior cavo-atrial junction. Optimal UVC position was defined as a catheter tip measuring between 0.5 cm below and 1.0 cm above the right hemidiaphragm medially on an AP radiograph (Visage 7, Visage Imaging Inc, USA). The ductus venosus begins at the left portal vein and enters the IVC closely related to the hepatic veins. ![]() The umbilical vein is found with the two umbilical arteries and travels to the inferior vena cava (IVC) via the left portal vein and ductus venosus. An umbilical venous catheter is used for vascular access in a neonate. ![]()
