What happens if i cough during total thyroidectomy surgery?

Not Good.: Very likely that your procedure will be performed under general anesthesia. Your anesthesiologist will be able to keep you “still”; generally speaking, coughing during the procedure would be very unusual. Most good anesthesiologists will also try to minimize coughing/straining even when patients are waking up ( i call this no “bucking around” time). Best wishes with your upcoming procedure.

You won't: You won't cough because you'll be under anesthesia.
