Patients who have overdosed on an Angiotensin II receptor blocker drug.
Patients are required to have central venous access.
Patients who are >18yo or who are > 14yo and > 50 kg
Have been adequately fluid resuscitated (i.e., > 30ml/kg within first 3 hours).
Have normal to supra cardiac output (Do not use in states of decreased LV systolic function).
Have failed to achieve goal MAPS on 2 or more vasopressors at doses >2 mcg/kg/min of norepinephrine (NE) equivalents (e.g. Norepinephrine, high dose epinephrine, vasopressin). Angiotensin II should NOT be used as a first line treatment.
In extreme situations angiotensin II may be considered especially when the patient has contraindications for VA ECMO.
There is no FDA approval for children <18yo. For patients 14 yo – 17 yo parents should be informed of the use of a non-FDA approved drug and writtenconsent obtained and placed in the patient chart prior to administration.
Any use outside the above parameters including patients <14yo or <50kg must also be approved by the CMO or their delegate. Written consent required prior to initiation.
Contraindications:
Allergy to mannitol or angiotensin II.
Patients with active bleeding AND hemoglobin < 7 mg/dl
Angiotensin II should NOT be used as a rescue therapy for moribund patients (i.e. expected not to survive >12 – 24 hours).
Current use of Angiotensin II Receptor Blocker or Angiotensin-Converting Enzyme Inhibitor
Patients receiving total NE equivalent dose > 1 mcg/kg/min are unlikely to benefit from angiotensin II. Use should be avoided in these patients.
Angiotensin II is a RESTRICTED formulary medication. All other use requires approval by the CMO or their designee.
