What Is a Yankauer Suction Catheter Used For? Clinical Applications Guide
What is a Yankauer suction catheter used for?
The Quick Answer
A **Yankauer suction catheter** is a rigid, curved oral suction device used to safely remove oropharyngeal secretions, blood, and debris to prevent aspiration during procedures or in compromised patients. It maintains airway patency during surgery, anesthesia, dental work, and emergency care—particularly valuable for tonsillectomies where it was originally developed.
Why We Ask This
Clinicians and caregivers often confuse Yankauer with flexible tracheal suction catheters, leading to inappropriate use in delicate airways or missed opportunities for safe oral secretion management in at-risk patients.
The Practical Science
The Yankauer's rigid plastic construction with a large-bore tip and protective bulbous head prevents mucosal trauma during suctioning. Its vented design allows controlled suction pressure regulation via thumb occlusion—critical for avoiding tissue damage while effectively clearing secretions.
In Clinical Practice
During a tonsillectomy, the surgeon uses the curved Yankauer tip to sweep the oropharynx between tissue removals, clearing blood without damaging healing tissue—enabling continuous visualization while preventing aspiration of pooled fluids.
