I regularly cure IB from people as a medic sometimes as synth. I prefer to od them to 52.5 with tribica and then kelotane/bica. The tricord will help offset higher od amounts. As a synth surgery is usually faster.
Only say that you should get permission to proceed with OD as although you are not harming them, you have the potential to do so if some bald medic walks by and gives them more bica. Then they panic and you have a kelo/bica od.
Also read into ghetto surgery much more. Being able to save a key role because you can crowbar open a ribcage is important. I have to do it at least twice a round.
Rest of the answers are good for me. Liked the story too.
