Injections are prepared using aseptic techniques to prevent infection. The specific preparation method depends on the type of injection and the medication being administered. Let's explore the process:
Preparing Injections: A Step-by-Step Guide
The process generally involves these key steps:
-
Gathering Supplies: This includes the medication vial, a suitable syringe, needles (often a different needle for drawing up the medication and administering it), alcohol swabs, and potentially a sharps container. The CDC emphasizes using aseptic technique throughout the entire process (CDC, Preparing Vaccines for Administration).
-
Preparing the Vial: Clean the vial's top with an alcohol swab. Allow it to dry completely before proceeding to avoid contamination.
-
Drawing the Medication: Draw the required amount of medication into the syringe, according to the prescribed dose (Drawing medicine out of a vial). Ensure accurate measurement to deliver the correct dosage. This step often involves removing excess air from the syringe. A new, sterile needle or a sterile blind hub should be attached for administration after removing the needle used for drawing the medication.
-
Inspecting the Syringe: Before administering the injection, visually inspect the syringe for any particulate matter or discoloration in the solution.
-
Administering the Injection: This step requires knowledge of the correct injection technique (intramuscular, subcutaneous, intravenous, etc.) and location. Proper techniques are crucial for effective drug delivery and to minimize discomfort and complications. (Preparing and Administering Intramuscular Injections).
Types of Injections and Considerations
Different types of injections require specific preparation methods:
- Vaccines: Vaccines often require careful handling and storage to maintain their efficacy. (Vaccine Storage and Handling Toolkit). Maintaining the cold chain is crucial for many vaccines.
- Compounded Medications: Some medications are compounded in pharmacies, and their preparation requires strict adherence to quality control standards to minimize the risk of contamination or adverse effects. (Evaluation of compounded bevacizumab prepared for intravitreal injection).
- Autologous Preparations: These are preparations derived from the patient's own tissues (e.g., platelet-rich fibrin). Their preparation involves specific laboratory procedures (Intra-articular injection of an autologous preparation rich in growth factors).
Safety and Training
Only trained and qualified personnel should prepare and administer injections. Proper training, including aseptic techniques and understanding of medication preparation, is critical to ensure patient safety (preparing injectable medications).
