Yankauer Suction Tube Size

Apr 25,2025

The Yankauer suction tube is a critical instrument in medical settings, primarily used for the effective removal of fluids during surgical procedures and airway management. Its design features a rigid, curved tube with a bulbous tip, allowing for efficient suctioning while minimizing tissue trauma.


Yankauer suction tubes come in various sizes to accommodate different patient needs and clinical scenarios. The sizing is typically measured in French units (Fr), where 1 Fr equals approximately 0.33 millimeters in diameter. Common sizes include:


  • 18 Fr (6.0 mm): Often used for pediatric patients or procedures requiring a smaller diameter.


  • 20 Fr (6.7 mm): Considered the standard adult size, suitable for general surgical and emergency applications.


  • 22 Fr (7.3 mm): Used in situations requiring higher suction capacity.


The length of Yankauer suction tubes can also vary. Standard lengths range from approximately 27 cm to 31 cm, allowing clinicians to select an appropriate length based on the procedure and patient anatomy.


Additionally, some Yankauer suction tubes feature design variations to enhance functionality. For instance, the "Hi-D Big Stick" Yankauer suction catheter has a larger inner diameter, nearly twice that of traditional surgical suction tips, facilitating more efficient fluid removal and reducing the risk of clogging.


Selecting the appropriate size and design of a Yankauer suction tube is essential for optimizing suction efficiency and ensuring patient safety during medical procedures.
