Which of the following is listed as a contraindication for the Combitube?

• A. Esophageal diseases
• B. Under 16 years old
• C. Over 7 feet tall
• D. Under 5 feet tall

Answer: (A)

Esophageal diseases are a contraindication for the Combitube because this device is inserted blindly and can place a cuff into the esophagus. In patients with esophageal pathology (like strictures, ulcers, varices, or prior esophageal surgery), inflating the esophageal cuff or forcing the tube into a diseased esophagus risks perforation, further injury, or compromising airway management. When such disease is present, a safer airway approach—typically endotracheal intubation with visualization or another appropriate device—is preferred. Height or pediatric age thresholds aren’t the limiting contraindications in this context, so they aren’t the reason for excluding use.
