The airlock technique is a method used to reduce pain during intramuscular injections. This technique involves injecting a small bubble of air (usually 0.2-0.3 ml) into the syringe after the medication. This air bubble creates a "lock" that prevents the medication from leaking back out through the needle track, which can cause pain.
Here are the key points:
- Purpose: Reduce pain associated with intramuscular injections.
- Procedure: Inject the medication first, then follow with a small amount of air.
- Mechanism: The air bubble prevents the medication from flowing back up the needle track.
Examples:
- The airlock technique is often recommended for medications that are irritating or staining, such as bortezomib.
- It is also used for injections into the ventrogluteal muscle, which is a common site for intramuscular injections.
Research:
Studies have shown that the airlock technique can be effective in reducing pain during intramuscular injections, especially when administered in the ventrogluteal site.
In conclusion, the airlock technique is a simple and effective method to minimize pain during intramuscular injections.
