Occult Causes of Non-Response to Vasopressors
vital disclaimer: the cognitive response to hypotension should not be reaching for a vasopressor. the primary therapy for hypotension is treatment of the underlying pathology
definition: patients who despite substantial vasopressor doses do not show HD parameter improvements. failure of response -> cognitive pause + consideration of reasons
considerations for non-responders:
- acidosis
- hypothyroid
- anaphylaxis
- adrenal insufficiency
- hypoCa2+
- occult bleeding
- toxicologic
- 2nd cause shock
