A little background on me, first: I am a CST, I've been scrubbing and assisting in the OR for a little over seven years now. I am currently taking pre-reqs for nursing school and I should hopefully be getting my RN, BSN within the next two years. I have scrubbed and assisted in thousands of surgeries- ranging from phacoemulsifications to spine 360's, CABGs, bowel resections, hearts, transplants of all kinds, etc.
It is very rare that a circulating nurse scrubs
in. The only time this really happens is if another scrub tech or assistant is unavailable, because as a circulator, you cannot leave your unsterile position in the operating room- what happens if we need something that isn't in the room? That's when the circulator goes and gets whatever is needed, and opens it onto the field!
So, if you are concerned about your wrist and retracting, I really think you will be fine; the only thing is, 70% of circulating is charting-- not good for carpal tunnel/ tendonitis.... You will definitely have to lift heavy patients, their limbs, and equipment on a daily basis. A 400+ lb patient is commonplace in our OR (Houston, TX, bariatrics) , so there is a lot of muscle required to be in the operating room.
Good luck with your future endeavors!!!
