Summary
Beta-blockers, particularly propranolol, effectively manage the severe hypermetabolic response following burn injuries. This treatment reduces inflammation, improves healing, and mitigates harmful physiological effects in burn patients.
Area of Science:
- Burn Injury Management
- Pharmacology
- Metabolic Response
Background:
- Severe burns trigger chronic inflammation and a persistent hypermetabolic state.
- This state, linked to elevated catecholamines and cortisol, causes immunosuppression, poor wound healing, muscle breakdown, and liver dysfunction.
- Beta-blockers are primary agents for mitigating these adverse effects.
Purpose of the Study:
- To review pharmacological mechanisms of beta-blockers in managing burn injuries.
- To evaluate the safety and efficacy of beta-blockers in burn patient care.
Main Methods:
- A literature search of the PubMed database was conducted.
- Relevant articles included randomized controlled trials, original research, and meta-analyses.
- Studies focused on pediatric and adult burn patients.
Main Results:
- Propranolol reduced insulin resistance, lipolysis, proteolysis, cardiac workload, and bone loss.
- It also decreased myocardial stress, resting energy expenditure, and central fat deposition.
- Propranolol remains the most effective therapy for burn-associated hypermetabolism.
Conclusions:
- Beta-blockers, especially propranolol, are crucial in managing the hypermetabolic response post-burn.
- Propranolol demonstrates significant efficacy in reducing multiple morbidities associated with severe burns.
- Further research is exploring adjunctive therapies like anabolic agents and exercise.

1.1K
β-receptor blockers significantly impact the cardiovascular system by counteracting catecholamine-induced sympathetic responses. These medications decrease heart rate, contractility, and cardiac output, potentially leading to cardiac depression, life-threatening bradycardia, and death. Therapeutically, β-blockers function as mild antihypertensives and are utilized in treating angina pectoris and cardiac arrhythmias. However, nonselective β-blockers inhibit β2-receptors in...

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

β receptors are classified into three subclasses: β1, β2, and β3. β1 receptors are primarily located in the heart and kidneys. When they get activated, they increase heart rate, contractility, and renin release. This process enhances blood pressure and aids in stress management. In contrast, β2 receptors are situated mainly in the lungs, blood vessels, and skeletal muscles. Upon activation, they trigger smooth muscle relaxation, causing bronchodilation and...

Third-generation β-blockers, such as labetalol and carvedilol, represent a significant advancement in managing cardiovascular conditions. Unlike conventional β-blockers, which can induce peripheral vasoconstriction, third-generation drugs block α1 adrenoceptors. This promotes vasodilation through several mechanisms, such as increased nitric oxide production, inhibition of calcium ion entry, opening of potassium ion channels, and antioxidant action. Labetalol, for instance, is...

β-adrenergic antagonists, or β-blockers, modulate the sympathetic nervous system by targeting β-adrenoceptors and inhibiting catecholamine-mediated sympathetic responses. β-blockers differ in their adrenoceptor subtype affinity, lipophilicity, and α-blocking capabilities. The history of β-blocker development began with the prototype, dichloroisoprenaline, which exhibited partial agonist activity. As a result, propranolol was developed as a pure antagonist but...

3.1K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
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...
