Trends in Use of Midodrine in the ICU: A Single-Center Retrospective Case Series

Objectives: Midodrine is an oral alpha-agonist approved for orthostatic hypotension. The use of midodrine as a vasopressor sparing agent has steadily increased in the ICU despite limited evidence for its safety in that setting. We describe the trends in use and reported side effects and complications of midodrine in multidisciplinary ICUs of a tertiary care institution. Design: Single-center retrospective case series. Setting: Medical and surgical ICU patients from January 2011 to October 2016 at Mayo Clinic, Rochester. Patients: Adult patients admitted to any ICU who received midodrine for hypotension were eligible. Interventions: None. Measurements and Main Results: We reviewed the mean arterial pressures and cumulative vasopressor dose before and after midodrine administration and assessed for reported complications. During the study period, a total of 1,119 patients were initiated on midodrine, 56% in surgical ICUs, 42% in medical ICUs, and 2% in the number of patients on vasopressors 24 hours after initiation of midodrine (663 to 344; p
