Yes I understand but a catheter and needle is what is different

"A needle is, well, a needle. That is, it is rigid, made of surgical steel, and not meant to remain in place. A needle is something that is intended to be inserted and quickly withdrawn. Conversely, a catheter typically is a flexible tube that can be of various sizes (dependent upon its intended purpose) and is intended to remain in place for a period of time- i.e. an “indwelling catheter”)."

All I'm saying is there not taking the time to place a catheter in on the field in the initial stages. A quick injection of morphine and then a catheter likely in the ambulance or at hospital at which point he's connected to a drip.
