Yankauer vs. Suction Catheter: Critical Differences Explained
What is the difference between Yankauer and suction catheter?
The Quick Answer
**Yankauer**: rigid plastic, curved tip with bulbous head, designed for *oropharyngeal* suctioning only. **Flexible suction catheter**: soft rubber/plastic, straight or angled tip, designed for *tracheal* suctioning through endotracheal tubes. Key distinction: Yankauer never enters the trachea; flexible catheters never should be used orally where they collapse under pressure.
Why We Ask This
Clinicians conflate these devices as interchangeable, leading to dangerous substitutions—like using a Yankauer for tracheal suctioning (impossible due to rigidity) or flexible catheters orally (ineffective due to collapse)—compromising airway safety during critical moments.
The Practical Science
Design differences reflect anatomical application: Yankauer's rigidity maintains lumen patency during oral suctioning against cheek/tongue pressure; flexible catheters navigate tracheal curves without causing mucosal injury. Each device's physical properties match its intended anatomical pathway.
In Clinical Practice
For an intubated patient with audible secretions, use a flexible catheter through the ET tube. For an awake post-op patient with oral pooling, use Yankauer orally—never substituting one for the other based on availability alone.
