Which procedure is definitive for removing a suspected airway foreign body in a choking toddler?

• A. Rigid bronchoscopy.
• B. Flexible bronchoscopy.
• C. MRI.
• D. Ultrasound.

Answer: (A)

When a toddler is choking with a suspected airway foreign body, the procedure that can definitively remove it must provide direct visualization of the airway, control of the airway, and a built-in way to retrieve the object. Rigid bronchoscopy does all of this in a single, controlled setting. It is performed under general anesthesia with the airway secured, allowing the clinician to directly see the trachea and bronchi and to use specialized forceps to grasp and remove the object. The rigid scope creates a stable conduit for ventilation and suction, which is crucial in a small child who can deteriorate quickly if the airway becomes blocked or edematous. Because of the larger and sturdier channel, the instrument allows effective retrieval of a broad range of objects and can manage bleeding or secretion without losing airway control. This combination of reliable visualization, airway security, and immediate extraction capability makes rigid bronchoscopy the definitive approach for removing a suspected airway foreign body in a choking toddler.

Flexible bronchoscopy can be useful in certain diagnostic or less-urgent situations, but it lacks the robust airway control and retrieval capability required for a definitive removal in young children. MRI and ultrasound do not provide the means to remove a foreign body and are not appropriate for acute airway obstruction—MRI is time-consuming and not suitable for emergent management, while ultrasound is not effective for visualizing or retrieving most airway foreign bodies.
