Midodrine and albumin as a possible “winning pair” in managing paracentesis-induced circulatory dysfunction: a clinical case report.

BACKGROUND: Paracentesis-induced circulatory dysfunction (PICD) is a “silent killer syndrome” occurring after large volume paracenteses (LVPs). We here report an unusual case of PICD induced by right heart failure recognized and managed successfully. CASE PRESENTATION: A 60-year-old woman was admitted to our Emergency Department for worsening dyspnea and hypoxia. Her medical history enclosed a chronic heart failure with reduced ejection fraction and post-stroke dysarthria associated to right hemiplegia. Clinical and laboratory examination defined a severe rightheart failure unresponsive to high-dose diuretic therapy. Diagnostic and therapeutic paracentesis was thus performed determining, initially, a progressive normalization of the abdominal volume, followed, subsequently, by a severe hypotension associated with an acute kidney injury (AKI) combined with severe hyponatremia associated with a normal cardiac output. In the hypothesis of a PICD, abdominal drainage and diuretic therapy were interrupted, reninemia sampling was performed, resulting in diagnostic, and treatment with albumin and norepinephrine was started. The latter was tapered and then replaced with Midodrine that conferred the possibility to reach clinical and laboratory stability, allowing relocation in a cardiological rehabilitation. PICD represents an independent predictor of mortality. Midodrine’s prophylactic use in PICD has been suggested as a cheaper alternative to albumin, as it appears to improve renal perfusion and reduce ascites with better clinical handling, as demonstrated in our patient. CONCLUSIONS: Our clinical case wants to show how not all PICDs are secondary to hepatic dysfunctions with Midodrine playing a possible therapeutic role by counteracting the pathophysiological mechanism in a rapid and non-invasive way, representing a valid therapeutic option in adjunction to albumin.
