All that follows is from the above resource.

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.
