I did it a few years ago and had a good time. I was going into FM and knew I wanted more opportunities to learn suturing skills, since as an MS-III I was on a surgical team where the attendings didn't think the third year RESIDENTS had sufficient practice at suturing 😛
I did lots of suturing, I&D, foreign body puncture wounds, splinting. It was mostly fast-track stuff. Dunno if the curriculum is still the same but it was fun. Definitely go for some of the weekend overnight shifts, you'll see lots of cool stuff. You'll get pulled into the traumas once they're stabilized to sew up their 100-suture head lacerations and such like. When I was there, we worked mostly with the PAs which was fine with me. If we were on fast track with the doc we tended to get pulled into ordinary fast-track stuff like the mother-baby sore throat: "Do you have a doctor for your baby?" "Well, yeah, but since we're both sick I figured it would be quicker to just come here." 🙄
You won't be taking care of inpatient decubs, don't worry - although we did get a presentation on hyperbaric as a treatment modality for that stuff.
