How to draw medicine from dural puncture needle

When pouring local anesthetic into the bag, some anesthesiologists break open the ampoule and pour it directly. This is also wrong, because when the ampoule is opened, there will be small broken glass shards, which will be poured directly into the box, and the broken glass shavings will be poured together.

Many people still use bupivacaine for spinal anesthesia. I remember that the director told me that the cerebrospinal fluid should not contain too many things. Due to the production process, we should minimize unnecessary steps. I usually use the 3 ml syringe in the puncture bag, install the filter inside, and ask the nurse to help me open the ampoule and then aspirate the liquid. This can reduce the time that the liquid in the ampoule is in contact with the air, and can filter the falling glass fragments.
