Management of Severe Hypotension with Midodrine

Appropriate Use of Midodrine

• The American College of Cardiology recommends noradrenaline (norepinephrine) as the vasopressor of choice for severe hypotension (SBP < 80 mmHg), particularly in trauma or shock settings 1, 2
• Midodrine can be considered for intradialytic hypotension, where it has shown efficacy in maintaining blood pressure during hemodialysis 3, 4

Recommended Approach for Severe Hypotension

• For trauma or shock-related severe hypotension, a restricted fluid replacement strategy should be attempted first to achieve SBP of 80-90 mmHg, followed by noradrenaline if fluid resuscitation fails 1, 5
• For orthostatic or dialysis-related hypotension, midodrine (5-10 mg) can be administered 30 minutes before dialysis or anticipated orthostatic challenge 3, 4

Safety Concerns and Monitoring

• The American Heart Association recommends using midodrine with caution in patients with congestive heart failure (CHF) or those taking negative chronotropic agents (beta-blockers, digoxin, non-dihydropyridine CCBs) 4
• Concomitant use of midodrine with other alpha-adrenergic agents like ephedrine or pseudoephedrine should be avoided 4
