What does a medical student do in the ER?

We can do all kinds of things in the ER under the loose supervision of one of the attendings. I have done 10+ cases of sutures, many staple sutures of head lacerations, rectal exams, pelvic exams, nasogastric tube placement, IV lines, blood draws, assist with intubations, CPR, cyst debridement, assist with traumas, assist with central line placements, and many others.etc. Many of these things we do unassisted and on our own. 

Most of these procedures depend on the confidence that the doctors have in your ability and your assertiveness. I love doing these procedures and get excited every time I get to do one. I imagine after doing many of these they would become less and less exciting.
