Tachycardia-polyuria syndrome after swan-ganz catheterization in liver transplant patient - A case report -

ABSTRACT

Background@#Tachycardia-polyuria syndrome is characterized by polyuria occurring because of tachycardia with a heart rate of ≥ 120 beats/min lasting ≥ 30 min. We report such a case occurring after swan-ganz catheterization.Case A 41-year-old male was scheduled for living-donor liver transplantation. After general anesthesia, atrial fibrillation occurred during swan-ganz catheterization, and polyuria developed 1 h later. During the anhepatic phase, the patient’s heart rate increased further, and cardioversion was performed. After a normal sinus rhythm was achieved, the patient’s urine output returned to normal. @*Conclusions@#The patient’s polyuria seemed related to the iatrogenic atrial fibrillation occurring during swan-ganz catheterization. Although we did not measure atrial natriuretic peptide, an increase in its concentration may have been the main mechanism of polyuria, as natriuresis was observed.
