Injecting a needle requires careful preparation and precise technique. This process varies depending on the injection type (e.g., intramuscular, subcutaneous) and the medication being administered. Always follow your doctor's or healthcare provider's instructions and any accompanying medication guidelines. This information is for general knowledge and should not be considered medical advice.
Preparing for Injection
- Gather supplies: Sterile needle and syringe (appropriate size for injection type and medication), alcohol swab, cotton ball or gauze, sharps container for disposal, and the medication itself. The specific supplies will vary depending on the type of injection and the type of medication. See the reference for specific instructions on the type of syringe/needle to use. (See references from MSKCC, Dupixent, and Immunize.org for examples)
- Hand hygiene: Wash your hands thoroughly with soap and water.
- Prepare the injection site: Cleanse the injection site with an alcohol swab, allowing it to air dry completely. The location of the injection site varies depending on the type of injection – intramuscular injections are given into the muscle, while subcutaneous injections are given under the skin. (See references from CDC, MN Health, and Alberta Health for examples on site selection).
Injection Techniques
The technique varies significantly based on the injection type. For example:
- Intramuscular (IM) Injection: Involves inserting the needle at a 90-degree angle into a muscle. Rapid injection of the medication is common (See reference from the video).
- Subcutaneous (SQ) Injection: Involves pinching the skin to create a fold, then inserting the needle at a 45-degree or 90-degree angle, depending on the patient's body fat, into the subcutaneous tissue (beneath the skin). (See references from MSKCC and Alberta Health)
Specific steps are detailed in the provided references, including visual aids for proper technique. (See references from MSKCC, Dupixent, Minnesota Health, Alberta Health, and Immunize.org)
Post-Injection
- Withdraw the needle: Remove the needle quickly and smoothly at the same angle it was inserted.
- Apply pressure: Apply gentle pressure to the injection site with a cotton ball or gauze to prevent bleeding or bruising.
- Dispose of sharps: Properly dispose of the used needle and syringe in a sharps container immediately.
Safety Considerations
- Always use sterile supplies: To minimize the risk of infection. (See CDC reference)
- Proper injection technique: To ensure the medication is delivered correctly and to avoid complications. (See references from all sources for varying techniques)
- Seek professional help: If you are unsure about any aspect of the injection process, consult a healthcare professional. (See references mentioning the necessity of professional guidance)
- Needle Exchange Programs: For individuals who inject hormones or other medications, accessing a needle exchange program is crucial for obtaining sterile supplies and safe disposal methods. (See Fenway Health reference)
