Brief Summary:
We hypothesize that midodrine treatment of refractory hypotension in patients otherwise ready for discharge from the ICU shortens duration of receiving IV vasopressors and SICU length of stay without increasing MGH length of stay or putting the patient at risk of being readmitted to an ICU.

Condition or disease Intervention/treatment Phase
Hypotension Critical Illness Drug: Midodrine Drug: Placebo Phase 3

Detailed Description:
Persistent hypotension in critically ill patients remains a major barrier to discharging patients from the intensive care unit (ICU). In our hospital, in patients with adequate tissue perfusion, midodrine has been observed to treat hypotension in order to wean continuous intravenous (IV) vasopressors and therefore promote ICU discharge. There are several possible etiologies of hypotension in the ICU. The most frequently seen causes include septic shock, hypovolemia, adrenal insufficiency, and idiosyncratic reactions from medications. For patients whose reversible causes of hypotension have been addressed but still require vasopressors, midodrine may prove to be a useful adjunctive medication to successfully increase blood pressure. No previous studies have examined the use of midodrine for the treatment of hypotension in an ICU setting. Therefore, we are investigating a new indication for midodrine as the treatment of hypotension in critically ill patients.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time until discontinuation of IV vasopressors [ Time Frame: IV vasopressors expected to be discontinued 1 day to 7 days after starting midodrine ]
    Measured hours from initiation of midodrine until discontinuation of IV vasopressors


Secondary Outcome Measures :
  1. ICU length of stay [ Time Frame: Patients are expected to be discharged from the SICU 5 to 7 days after starting midodrine ]
    Measured number of days from initiation of midodrine until discharge ready from the ICU

  2. Hospital length of stay [ Time Frame: Patients are expected to be discharged from the hospital 2 to 4 weeks after starting midodrine ]
    Measured number of days from initiation of midodrine until discharged from hospital

  3. Rates of ICU readmission [ Time Frame: Expected that patients will be followed 1 to 2 weeks after discharge to assess rates of readmission ]
    Number of patients initiated on midodrine that are readmitted back to ICU after being discharged to floor

  4. Rates of hypertension, bradycardia, and hemodynamically significant tacharrythmias [ Time Frame: Rates of side effects will be followed while patient is on midodrine which is expected to be 5 to 7 days ]
    Measured rates of hypertension (increase in systolic blood pressure to values higher than those set by the primary team or greater than 160 mmg), bradycardia (decrease in heart rate to values lower than those set by the primary team or less than 40 BPM), hemodynamically significant tachyarrythmias (greater than 20 mmhg decrease in systolic blood pressure).
