Drawing up medication safely involves preparing the vial, instilling air, withdrawing the correct dose, and removing air bubbles to ensure accuracy and sterility.
Step-by-Step Guide
1. Prepare Your Workspace and Supplies
Gather all necessary items: the medication vial or ampule, the correct syringe and needle, alcohol prep pads, and a sharps container. Wash your hands thoroughly with soap and water or use an alcohol-based hand rub to prevent contamination
2. Inspect the Medication
Check the vial for cracks, expiration date, and any discoloration or particulate matter. For multi-dose vials, ensure the discard date is within the recommended timeframe
3. Clean the Vial
Remove the vial cap and wipe the rubber stopper with an alcohol prep pad for at least 30 seconds. Allow it to air dry before inserting the needle
4. Prepare the Syringe
Remove the syringe from its packaging without touching the needle. Pull back the plunger to draw in air equal to the volume of medication you plan to withdraw
5. Instill Air into the Vial
Insert the needle into the center of the vial and gently push the air into the vial. This prevents a vacuum from forming, making it easier to withdraw the medication
6. Withdraw the Medication
Turn the vial upside down with the needle still inside. Keep the needle tip below the fluid level and slowly pull back the plunger to draw the prescribed dose
7. Remove Air Bubbles
Hold the syringe upright, tap gently to move bubbles to the top, and slowly push the plunger until all air is expelled, allowing only a drop of medication to escape to maintain accuracy
8. Change Needles if Necessary
If using a filter needle for an ampule, replace it with a standard injection needle before administration to prevent glass particles from entering the patient
9. Administer or Prepare for IV
Attach the syringe to the injection site or IV line as instructed. For IV medications, flush the line with saline before and after administration, following proper technique
10. Dispose of Supplies Safely
Discard all used needles, syringes, and vials into a sharps container. Ensure the lid is closed to prevent accidental injury
Key Safety Tips
- Always verify the medication and dose before drawing up.
- Avoid touching the needle or allowing it to contact any surface.
- Draw air into the syringe equal to the volume of medication to prevent vacuum issues.
- Work in a clean, well-lit area to maintain sterility.
- Following these steps ensures that medication is drawn up accurately, safely, and in a sterile manner, minimizing the risk of contamination or dosing errors
