Precautions for using Yankauer suction tube

When using the Yankauer suction tube, the core objective is to strike a balance between efficient suction and tissue preservation. Here are some key clinical considerations:

1. Choose the appropriate size
• Adult vs. Child: Adult sizes have a larger tip. If used in surgeries performed on children or in confined spaces (such as dental procedures), this may obstruct the field of vision or damage tissue. In these cases, a smaller suction tube specifically designed for pediatric use should be used.

2. Strictly Adjust the negative pressure
• Pressure control: Suction pressure should not be too high. Adults should generally be adjusted to 100-150 mmHg, and children should have even lower pressure. Excessive pressure can easily lead to tip blockage and increases the risk of tissue damage and tube removal injury.
• Testing: Always test the suction power with sterile water before use to ensure it is working properly.

3. Standard Operating Procedures
• Utilize the Vent: The vent on the handle is crucial. Block the vent with your finger to suction, and release it to stop. Remember to release your finger when not suctioning; this allows for precise control and prevents the suction tip from adhering to surrounding tissue.
• Avoid Forceful Operation: Be gentle, especially in vulnerable areas such as the pharynx and esophagus. Never use the suction tube tip to poke or forcefully separate tissue, as this can cause perforation or bleeding.

4. Be Aware of the Risk of Blockage
• Note the Material: The transparent plastic tube body allows for easy observation. If suction suddenly becomes difficult or blood return is slow, check immediately.
• Prompt Flushing: If the suctioned material is viscous (such as sputum or blood clots), immediately flush the lumen with sterile saline to prevent coagulation and blockage.

5. Strict Aseptic Techniques
• Single Use: Modern suction tubes are mostly single-use aseptically packaged. Use immediately after opening and discard. Re-sterilization is strictly prohibited (unless it is made of a specific re-sterilizable metal material).
• Operating Area: Maintain sterility during suctioning. Do not touch non-sterile areas.

6. Tube Removal and Finishing
• Disconnection Before Removal: Before removing the tube, loosen the connection or turn off the negative pressure source. Wait until suction disappears before removing the suction tube to avoid damaging the mucosa.
• Proper Disposal: After use, discard directly into a medical waste container (sharps box or yellow trash can). Do not allow the suction tube tip to protrude to avoid injuring others.
