When I did ED clinicals (and ICU, L & D, and floor) I did something that no one had ever heard about; but worked great for me and some people that have I told.
I go in and introduce myself to the charge nurses, helped with room checks; then go and find the supply carts and went and restock EVERY room with medical supplies. Then go and find the linen cart and restock every room with linens. I did this at the beginning of every shift; and halfway through the shift, and usually towards then end if I had time.
The charge nurses saw what I did and took me to the Residents in charge of the shock/trauma rooms and told them that whenever they had good things I was to be involved in it.
The Charge nurses would overhead page me when good things were coming in; a few of the residents would have me shadow them and I would be with them when they answered the radios and phones when trauma and medical alerts were called in (only things we had to call in there).
As I was cleared for different things in class I got to do intubations in the ED, I needle decompressed 2 chests (in 1 shift). I helped to do 2 chest tubes; and a couple shifts later when it really got busy I did a chest tube on one side while the resident did one on the other side.
I got to do a needle stick (can't remember the proper name for it) for a pericardial tamponade; the Resident that was guiding me told me it was only his 2nd one; and the only reason he let me do it was the charge nurse threatened him if he wasn't nice to me LOL. Which I later had to do in the street so it was really helpful to do in the ED before hand.
I was in the room when resident cut open a chest and I got to do open chest heart massage.
I had a few residents and staff doc's ask how much I bribed the Charge nurses, and I responded I was just nice to them. A couple of new residents watched me when they saw me on the schedules and started doing the same things. Nurses treated them nicer after that.
Even other medic students in my class told me it was a waste of time and I was crazy to do it; but out of 18 students in my class I was the only one to Needle decompress a chest in the ED or stick a pericardial tamponade or do a chest tube. Only 3 of us got tubes in the ED.
