About this trial
This randomized, double-blind, placebo-controlled trial evaluates whether oral furosemide 40 mg, initiated 12 hours postpartum, reduces hospital length of stay compared to placebo (folic acid 5 mg) in postpartum women with severe preeclampsia. Secondary outcomes include need for rescue antihypertensive medications, weight reduction, and metabolic safety (hypokalemia, renal function). A total of 186 participants (93 per arm) will be enrolled across two hospitals in Honduras.
