The hemodynamic effects of intravenous digoxin-binding fab immunoglobulin in severe preeclampsia: a double-blind, randomized, clinical trial.

Objective: An endogenous digitalis-like factor (EDLF) has been implicated in the pathophysiology of preeclampsia (PE). This hypothesis is supported by two cases of preeclampsia in which administration of digoxin immune Fab (DIF) reduced mean arterial pressure (MAP).

Study Design: To study this observation further, we performed a double-blind, placebo-controlled, randomized clinical trial to examine the effects on MAP of intravenous DIF given after delivery in 26 subjects with severe preeclampsia.
