Local anesthesia

1. Insert the needle into the tissue at the end of the laceration.
2. Advance the needle parallel to the laceration to the length of the needle while injecting the anesthetics continuously. Note the skin rising (and blanching if the local anesthesia is combined with a vasoconstrictor like adrenalin) as you deposit the fluid.
3. With a laceration longer than the needle, make sure to enter the skin at an already anesthetized point. Repeat at the other side of the laceration.
4. Lastly make sure to deposit anesthesia in the deeper layers of the skin.
