Special Injection Techniques

[01dragonslayer]

The purpose of the below injection techniques is to seal the injected compound deep within the muscle, by allowing no exit path back into the subcutaneous area and skin. While using these techniques is not essential to performing a proper injection, they will allow the user to minimize oil loss due to seepage.

• Z-track Technique: A technique utilized to prevent leakage of the injected substance post-injection.
• Air Bubble Technique: A technique utilized to prevent leakage of the injected substance post-injection.

Z-track Technique​

The Z-track method requires temporarily displacing the skin & subcutaneous tissue prior to injection and immediately releasing the tissue post-injection. In order to perform the Z-track method, prepare your syringe and be ready to inject. Once the syringe is in hand, use your free hand to pull the skin at the injection site ½-1 inch away from its original location. While continuing to hold the skin in this stretched position, administer the injection into the original location. Immediately after removing the syringe from the injection site, release the skin which was being held in place. The Z-track method works best at locations where there is a greater amount of lose skin. Utilizing locations with taut skin will be more difficult.

Air Bubble Technique​

The air bubble technique involves injecting a small amount of air at the end of an injection. In order to perform this technique prepare your syringe and be ready to inject. When the syringe is in hand, pull ½ cc/mL of air into the syringe. Just prior to and throughout the injection, make sure the needle is pointing down, so that the air floats to the top of the barrel (near the plunger) and is the last thing to be injected into the muscle, as it is this small air bubble which will help to seal off the opening and prevent leakage. This is also used by some to make sure all of the liquid they are injecting is out of the needle.
