Question

air bubbles are present in the medication in the syringe that has been withdrawn from an ampule?

Answer 1

When air bubbles are present in the medication in the syringe that has been withdrawn from an ampoule we should gently but firmly tap syringe to remove air bubbles. The proper method involves removing the cap from the needle and drawing up into syringe amount of air equal to the volume of medication to be withdrawn. (For example, when we need to draw up 3 mL of fluid, we should draw up 3 mL of air). Insert the needle into the upright vial through the center of the rubber cap, the sterility of needle should be maintained. Inject air into the vial. While holding onto plunger, we should invert vial and remove the desired amount of medication and withdraw the needle. Hold syringe and vial at eye level and determine that correct dosage is drawn into the syringe.
