The demonstrations and aseptic technique are awesome, however I must add to never recap by holding. Please use the scoop method to prevent distractions causing needle stick.
This video is not that old, I am surprised that the technician is not wearing a mask or goggles. It is for the protection of the technician but also the patient receiving that drug...
@b4yonce I'm in high school so I'm not an expert on this; however, I do believe that the venting needle is to equalize the pressure inside the vial as you insert fluid contained in the diluent syringe. Hope that helps. Again, I'm only in high school so I could be wrong.
Use the 'fishing' method to recap a needle--chase the cap with the needle on the syringe and then use the tabletop to 'click' it back into the cap. Capped needles are less of a problem than uncapped needles, unfortunately.
Some drugs expel gas on reconstitution, so a vent provides escape for pressure build-up. But, the most significant use of a vented needle is for use in cytotoxic anti-neoplastic or chemotherapy preparations to draw up reconstituted liquid by preventing toxic, aerosolized materials from leaving the container during filling.
Yes, it's good to hold the vial and syringe in a 90 degree angle or close to it if you're working in a vertical flow hood so you don't block the airflow.
Yeah never re-cap a needle. Even if the only risk is a sterile needle scratches you that requires filling an accident report if you do. There are self-sheathing needles if you can't keep a waste box in the cabinet.
Good thing you're using the the ring and pinky fingers otherwise you might stick yourself in one of the other fingers that are attached to your body, who know what might happen then.
