I second the fact that the drunks in the ER are an excellent source of suture experience. However, I do have a word of warning in the form of my most traumatizing experience in med school:
It was my 3rd week in trauma surgery and I was happily suturing away on a drunk with suspected schizo whose ETOH levels indicated a likely comatose state(even if he was an elephant). Then out of nowhere, in one swift display of superman strength, he flails wildly out of his restraints, knocking down everything in sight, also managing to bury the suture needle in my forearm. After everything dies down and said drunk is tied down again(this time not with the "soft" restraints), the resident appears and announces that he's not schizo after all, but is likely suffering from the advanced stages of HIV encephalopathy - due to his viral count of 18 million😱
It was like slow motion to me, I look down at my arm and look up to see the staff looking at me like I'm already dead. Long story short, I took those damn HIV cocktails for 6 weeks(highly unpleasant- understand the noncompliance now) until my labs came back negative 😀 It's funny now, but I was completely convinced I was going to die.
Anyway, this story isn't meant to scare anyone, but don't be stupid like me- those drunks are walking disease vectors(HIV, Hep, etc.) approach with caution.
It's better to be lucky than good any day of the week!😉
