Insights
Acute stridor in children can mimic croup but may indicate anaphylaxis. Prompt recognition of allergic triggers and adrenaline treatment are crucial for life-saving outcomes in pediatric emergencies.
Area of Science:
- Pediatric Emergency Medicine
- Allergy and Immunology
- Critical Care
Background:
- Acute stridor in children is often misdiagnosed as croup.
- Anaphylaxis can present with symptoms similar to croup, including stridor.
- Timely diagnosis and treatment are critical for managing pediatric stridor.
Abstract:
Acute stridor is frequently equated with croup in pediatric contexts; however, other conditions, such as anaphylaxis, may present with remarkably similar clinical and radiographic characteristics. This article presents two pediatric cases of acute stridor initially managed as croup but ultimately diagnosed and treated as anaphylaxis induced by seafood ingestion. Both patients experienced recovery following the administration of intramuscular adrenaline. These cases underscore the necessity for increased vigilance and comprehensive history-taking when evaluating pediatric acute stridor. Identifying allergic triggers and administering timely treatment can be lifesaving.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Respiratory Failure-IV
Allergic Reactions: Anaphylaxis
Diphtheria
