[Successful therapy of hepatorenal syndrome with norepinephrine].

A 39-year-old female with alcoholic cirrhosis was admitted with signs of an alcoholic hepatitis. Within one week a hepatorenal syndrome (HRS) (Creatinin 5.83 mg/100 ml, Harnstoff 235 mg/100 ml) evolved in the absence of additional causes. She had a diminished water (urine volume 31 ml/h) and sodium excretion (10 mmol/l). Urine flow was increased to 131 ml/h by plasma expansion with i.v. infusion of volume and albumin and with infusion of dopamine (3 micrograms/kg/min) and, as there was no diuretic pretreatment and thus, no HRS secondary to diuretic treatment, furosemide (500 mg/24 h). However, impairment of renal function remained unchanged with this therapy. Therefore, norepinephrine (NE) therapy was initiated. A dosage of 0.1-0.12 microgram/kg/min was necessary to achieve the desired increase in the mean arterial pressure of 10-20 mm Hg. During the NE infusion the urine volume increased further to 231 ml/h, the sodium excretion raised to 44 mmol/l, and serum levels of creatinine and urea decreased to 1.91 mg/100 ml and 141 mg/100 ml, respectively. With recovering liver function the NE infusions could be discontinued after 5 days without recurrence of a HRS until discharge after 3 weeks. Beside the vasopressin analogon ornipressin, the combination of norepinephrine and dopamine seems to be useful for the therapy of HRS. Norepinephrine has the advantage of an easy accessibility in ICUs and seems to exert less side effects.
