Ans. is 'a' i.e., Foreign body "Choking and coughing episodes accompnied by wheezing are highly suggestive of airway foreign body" - Nelson "Foreign body aspiration should always be considered as a potential cause of stridor and airway obstruction in children". --- O.P. Ghai Foreign body aspiration o Infants and toddlers use their mouths to explore their surroundings. So, they are very prone to aspirate a foreign body. o The most common age group is 6 months to 4 years. o Most common foreign body aspirated is nuts (peanuts). o Most airway foreign bodies lodge in a bronchus (right more than left). Clinical manifestions Three stages of symptoms may results : - 1. Stage I - Initial event --> Violent paroxysm of coughing (most common symptom), choking, gagging and wheeze immediately after aspiration. If obstruction is complete, child may be unable to vocalize (aphonia) and there may be cyanosis. If obstruction is incomplete drooling and stridor may occur. 2. Stage H Asmptomatic --> The foreign body becomes lodged, reflex fatigue and immediate irritating symptoms subside. This stage is most tracherous and account for a large percentage of delayed diagnosis and overlooked foreign bodies. 3. Stage III - Complications --> Obstruction, erosions or infection can cause fever, hemoptysis, pneumonia and atelectasis. The most serious complication offoreign body aspiration is complete airway obstruction.
