Midodrine for the Treatment of Refractory Hypotension

Phase 3
Completed
Conditions
Critical Illness
Hypotension
Interventions
Drug: Placebo
Registration Number
NCT01531959
Lead Sponsor
Massachusetts General Hospital
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.

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.

Time Until Discontinuation of IV VasopressorsFrom initiation of the study drug until discontinuation of IV vasopressors, assessed up to 400 hours

Measured hours from initiation of midodrine until discontinuation of IV vasopressors

Secondary Outcome Measures
NameTimeMethod
Hospital Length of StayFrom initiation of midodrine until hospital discharge, assessed up to 90 days

Measured number of days from initiation of midodrine until discharged from hospital

Rates of ICU ReadmissionUp to 2 months after ICU discharge

Number of patients initiated on midodrine that are readmitted back to ICU after being discharged to floor

Rates of Hypertension, Bradycardia, and Hemodynamically Significant TacharrythmiasFrom initiation of the study drug until discontinuation of the study drug, an average of 59 hours.

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).

ICU Length of StayFrom initiation of midodrine until ICU discharge, assessed up to 45 days

Measured number of days from initiation of midodrine until discharge ready from the ICU
