Hypoglycaemia in neonates can be caused by malposition of the umbilical artery catheter (UAC). If the tip of the umbilical arterial catheter is located next to the origin of the great abdominal vessels glucose infusion is mainly directed into the coeliac trunk and superior mesenteric artery. Direct stimulation of the pancreatic gland might then result in hyperinsulinaemic hypoglycaemia. Generally, UAC position is controlled by x-ray. When using ultrasound for location of the UAC the exact topography and especially the relation of the tip of the UAC to the great vessel lumina can be documented precisely.
新生儿低血糖可能由脐动脉导管（UAC）位置不当引起。如果脐动脉导管尖端位于腹主动脉大分支起始部附近，葡萄糖输注主要进入腹腔干和肠系膜上动脉。这可能直接刺激胰腺，进而导致高胰岛素血症性低血糖。一般来说，UAC位置通过X线控制。使用超声定位UAC时，可以精确记录其确切的局部解剖结构，尤其是UAC尖端与大血管管腔的关系。
