Swiping of oral cavity not to be done in foreign body ingestion in children because
Airway obstruction is treated with a sequential approach, staingwith the head-tilt/chin-lift maneuver to open and suppo the airway, followed by inspection for a foreign body, and finger-sweep clearance or suctioning if one is visualized. Blind suctioning or finger sweeps of the mouth are not recommended. A nasopharyngeal airway or oropharyngeal airway can be inseed for airway suppo if indicated.A conscious child suspected of having a paial foreign-bodyobstruction should be permitted to cough spontaneously until coughing is no longer effective, respiratory distress and stridor increase, or the child become unconscious.(Refer: Nelson's Textbook of Pediatrics, SAE, 1st edition, pg no. 492)
