Occult causes of non-response to vasopressors
- Primary therapy for hypotension is to treat the underlying cause, while initiation of vasopressors is a temporary adjunctive therapy
- Despite substantial vasopressor doses, some patients may not respond appropriately with improvements in hemodynamic parameters; failure to respond should lead to a cognitive pause and consideration of the occult causes of non-response to vasopressors.

Be sure and review the YouTube video, Push-Dose Pressors [Epinephrine and Phenylephrine], March 14, 2019 from CORE EM. The video shows you how to prepare syringes of the two medicines.
Every clinician responsible for caring for critically ill patients [even if it is only until the helicopter arrives (critical access hospitals)], needs to review these outstanding resources: Dr. Weingart’s EMCrit and Dr. Farkas’ Internet Book of Critical Care and PulmCrit.
