Background: Early mobilization is an important therapeutic goal after total knee replacement and total hip replacement. Orthostatic hypotension and orthostatic intolerance can impede mobilization. Midodrine hydrochloride, an orally administered vasoconstrictor, may improve blood pressure and diminish the prevalence of adverse mobilization events. Methods: We conducted a pilot change-of-practice study. Two cohorts, each comprising 10 patients managed with total knee replacement and 10 patients managed with total hip replacement, were managed with blood pressure-adjusted midodrine, which was administered 3 times daily for the first 72 hours postoperatively at either a low dose (2.5 or 5 mg) or..View full abstract
