| pubmed-article:7846755 | pubmed:abstractText | Digitalis intoxication is a common problem, mainly because of the narrow margin of safety of digoxin. These patients may have concomitant renal failure. In patients who have renal failure and who have been treated with digoxin-Fab, the elimination of the digoxin-Fab complex is significantly delayed, and there is a risk of dissociation of the complex with rebound of free digoxin and recurrence of toxicity. The high molecular weight of digoxin and digoxin-Fab complex prevents its elimination by hemodialysis or continuous arteriovenous hemofiltration. A 3-day-old newborn with digoxin overdose and acute renal failure was treated with digoxin immune Fab and peritoneal dialysis. Low levels of total digoxin were measured in the dialyzate, indicating poor elimination of the digoxin-Fab complex through peritoneal dialysis. | lld:pubmed |
