That's country specific, maybe you should use port and starboard. Really though, just use _your_ left and right as most people do, because as has been mentioned, the standard is for doctors to refer to and visualise left and right from the patients perspective - so every time you do something different they have to transform, translate or clarify which increases chance of mistakes.
