Which is a contraindication for Combitube use?

• A. Under 16 years old
• B. Severe facial trauma
• C. Allergic to latex
• D. History of COPD

Answer: (A)

The essential point is that Combitube use is not appropriate for pediatric-sized airways. This device is designed and validated for adults, with cuffs and dimensions that fit an adult oropharynx and airway anatomy. In children under 16, the airway is smaller and more delicate, and the dual-lumen, blind-insertion design increases the risk of misplacement, airway trauma, or gastric insufflation. For this reason, being under 16 is an absolute contraindication.

Other options don’t represent absolute contraindications. Severe facial trauma can complicate placement but isn’t an automatic rule against using a blind airway device in all cases; clinicians may still use alternative tools if needed. Latex allergy can be managed with latex-free equipment, so it isn’t a contraindication. A history of COPD doesn’t by itself prevent Combitube use, as the device can still provide ventilation if placed correctly.
