Most important: Document it!
As doctors you have a certain leeway and are allowed a little flexibility in your approach to treatment as long as one doesn't get reckless. So if moving into uncharted territory, document it on all case files what you are doing and why.

Often I get into scenes where I would or would not like to operate a patient while many others would take a contrary stand. I make sure the rationale of my decision is on paper. That makes you medicolegally safe as well as allows you individual thinking.
