Prevention of accidental childhood strangulation: where is the site of obstruction?

BACKGROUND

Accidental strangulation is a preventable problem with limited scientific understanding in children. Children's clothing and household furniture have the potential to cause strangulation. Localizing the site of obstruction would provide understanding and insight to preventing this unfortunate event.

METHODS

While undergoing the application of pressure to the submental and suprahyoid region in eight patients flexible endoscopy was performed to evaluate the location of obstruction.

RESULTS

Submental pressure occluded the nasopharynx and oropharynx. Suprahyoid pressure occluded the larynx.

CONCLUSIONS

In suspension strangulation, airway obstruction appears to occur at the level of the larynx involving the epiglottis and the arytenoids. Increased knowledge regarding site of airway occlusion may help to decrease the hazard of accidental strangulation.
