I assume it comes with practice, but since this is the pre-med forum....you might want to ask this in one of the medical forums...then, actual surgical attendings, fellows or residents would be able to answer your question, with the right answer.
Actually that's incorrect. The specialty forums are for questions of interest to residents/fellows/attendings in those specialties. Any question asked by a pre-med or medical student gets moved right back to those forums.
Honestly, we come here to look for questions we can answer, so this is the proper place.
Ok...tremors.
Everyone's got them. Even surgeons. My hands are pretty steady (I don't see a tremor) but as one of my attendings used to say, "we all have tremors, I just don't want to know how much of one you have".
The "tricks" to hiding them?
- cut back on caffeine and other stimulants
- try to not be nervous (easier said than done and when in residency, I was always nervous with a new attending and my hands would shake)
- beta blockers if really bad
- resting your hand on the patient
- using the correct size instruments
In the vast majority of cases a normal resting tremor is not going to preclude you from being a surgeon; heck, even a significant tremor doesn't in most cases. Microvascular work? That's an issue but so few people do that work, that its not going to be a problem for most people.
All in all, a tremor is normal. Everyone has one. It won't stop you from being a surgeon as long as you can control it to some degree.
