R06.1

Clinical Causes: Infections like croup or epiglottitis Allergic reactions causing airway swelling Foreign body obstruction in the airway Laryngeal or tracheal tumors Vocal cord paralysis or dysfunction Trauma or injury to the airway Congenital abnormalities such as laryngomalacia Inflammatory conditions including relapsing polychondritis Anaphylaxis leading to airway swelling

Key Symptoms: Sudden onset of high-pitched breathing sounds, especially during inhalation Difficulty breathing or shortness of breath Struggling to breathe or increased effort to breathe Cyanosis, or a bluish tint to lips or face in severe cases Changes in voice, including hoarseness or muffled sounds Occasional cough that may accompany breathing difficulties Restlessness or anxiety due to breathing struggle Difficulty swallowing if swelling involves the throat

Diagnosis Path: Thorough medical history evaluation Physical examination focusing on the neck, throat, and respiratory system Endoscopic procedures like laryngoscopy or bronchoscopy to visualize the airway Imaging studies such as X-rays or CT scans to identify structural abnormalities or obstructions Laboratory tests if an infectious or allergic process is suspected

Treatment Protocols: Emergency interventions like oxygen therapy to ensure adequate oxygenation Medications such as corticosteroids to reduce inflammation and swelling Epinephrine for severe allergic reactions featuring airway swelling Airway management procedures, including intubation or tracheostomy in critical cases Addressing the root cause, like removing a foreign object or treating infections Surgical options in cases involving structural abnormalities or tumors Supportive care including hydration and monitoring respiratory status
