Angiotensin II Use in Refractory Multisystem Shock: A Case Report

Area of Science:

• Critical Care Medicine
• Pharmacology
• Trauma Surgery

Background:

• Distributive (vasodilatory) shock is a frequent and challenging condition in intensive care units (ICUs).
• Treatment resistance and tachyphylaxis to standard vasopressors complicate management.
• Multisystem trauma can precipitate severe vasodilatory shock requiring aggressive interventions.

Observation:

• A 56-year-old male trauma patient presented with hemodynamic instability and multisystem injuries.
• Despite aggressive resuscitation and multiple vasopressor therapies, the patient's condition deteriorated.
• The patient developed ischemic bowel, necessitating surgical resection, with a guarded prognosis.

Findings:

• Angiotensin II (ATII), a newly approved vasopressor, was administered as a last resort.
• The use of ATII demonstrated a positive therapeutic effect in managing refractory vasodilatory shock.
• This case highlights ATII's potential utility in complex critical care scenarios.

Implications:

• Angiotensin II may offer a viable alternative for patients with vasodilatory shock refractory to conventional treatments.
• Further research into ATII's efficacy and safety in diverse critical care populations is warranted.
• This case expands the therapeutic armamentarium for managing life-threatening distributive shock.
