Vasopressin has been used in neonates for refractory hypotension. Elevation in liver enzymes due to mesenteric mucosal hypoperfusion has been associated with the use of vasopressin in adults. We present a case of a neonate that develop elevated liver enzymes in association with vasopressin use and migration of umbilical venous catheter.

Vasopressin has been used in neonates for refractory hypotension. Elevation in liver enzymes due to mesenteric mucosal hypoperfusion has been associated with the use of vasopressin in adults., We present a case of a neonate that develop elevated liver enzymes in association with vasopressin use and migration of umbilical venous catheter (UVC).
A male infant on day 10 of life developed Gram-negative sepsis and refractory hypotension. Vasopressin drip (0.04 units/kg/h) was added to dopamine and epinephrine drips infused through an UVC. Vasopressin was discontinued on day 14 of life (total 4 days of continuous drip) as infant's blood pressure improved. [Table 1] depicts the serial serum liver enzyme levels.
We postulated that a combination of UVC migration and vasopressin infusion has resulted in the transient elevation of liver enzymes. UVCs are commonly placed in neonates for intravenous access. The preferred location of the tip of the UVC is the cephalad portion of the inferior vena cava or at the inferior vena caval-right atrial junction., We noticed the caudal migration of UVC. [Figure 1] shows the comparison on the position of UVC. In addition to anasarca noted on second X-ray, the UVC is noted to have migrated caudally, represented by asterisk. Liver ultrasound [Figure 2] showed UVC in the right hepatic vein with normal Doppler study.

Hepatic injuries have been reported in associated with UVC., Despite of abnormal liver function tests, we did not note any structural damage to the liver on US with preserved circulation. Vasopressin is a potent vasoconstrictor that may lead to hypoxic liver injury resulting in elevated enzymes. We postulated that a combination of UVC migration and vasopressin has resulted in transient elevation in the liver enzymes in this neonate.
In conclusion, UVC position and liver enzymes should be monitored closely when vasopressin is used in neonates.
