This review examines vasoactive agents for severe burn shock and septic shock, highlighting synthetic angiotensin-II (AT-II) as a potential new therapy. Research is needed to confirm its effectiveness in burn patients.
Area of Science:
- Critical Care Medicine
- Trauma Surgery
- Pharmacology
Background:
- Severe burn injuries often lead to shock, requiring vasoactive agents for hemodynamic support.
- Existing therapies like catecholamines and vasopressin have limitations, prompting exploration of novel agents.
- The renin-angiotensin-aldosterone system (RAAS) is frequently dysregulated in burn and septic shock.
Purpose of the Study:
- To review current vasoactive agents used in acute burn shock resuscitation.
- To explore the potential role of synthetic angiotensin-II (AT-II) in managing burn and septic shock.
- To discuss the physiological rationale and existing data for synthetic AT-II in shock.
Main Methods:
- Narrative review of existing literature on vasoactive agents in burn and septic shock.
- Analysis of the pathophysiology of burn injury and its impact on the RAAS.
- Evaluation of available data on synthetic AT-II in distributive shock populations.
Main Results:
- Catecholamines and vasopressin are standard but have drawbacks.
- Synthetic AT-II shows promise in improving hemodynamics in other distributive shock cases.
- Limited data currently exists on synthetic AT-II specifically for acute burn shock and septic shock in burn patients.
Conclusions:
- Synthetic AT-II presents a potential therapeutic option for severe burn and septic shock.
- Further research is crucial to establish the safety and efficacy of synthetic AT-II in burn populations.
- Understanding RAAS dysregulation in burn shock is key to optimizing treatment strategies.

Burn Injuries
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
