All surgery requires the set of medical tools in the Operating Theatre, along with a table (a surgical table gives no negative results). For the most part, only medical doctors and the Chief Medical Officer can perform advanced surgery.
For every step there are ghetto analogues. Using them lowes chances of performing a step correctly, wounding your patient. Hover your cursor over the item's picture to see its name. Next to the items are the success rates.
General
Step 1: Place the patient onto the operating table.
If there is no table, you can use: any table (80%), any bed (70%), ask them to lie on the floor (50%). Chances of successfully completing every step will be reduced.
Step 1.5: (Optional) Use a tank of anesthetic and a breath mask to make your patient sleep.
Step 2: Place drapes or bedsheet over the part of body you are operating.
Step 3: Switch to help intent.
Step 4: Aim at the appropriate body part (important!).
Step 5: Do the surgery.
Step 6: Wake up the patient and kick them out.
Additionally, how to do self-surgery
Step 1:Get yourself an roller bed
Step 2: Adquire the surgery tools required for operation. Usually they are on Surgery.
Step 3: Hold the tool you need (drapes count as tools) in hand. This is important
Step 4: Lay yourself on the roller bed (click + drag on the roller bed)
Step 5: Use the tool on yourself (click on yourself)
Step 6: Get up (resist/click on roller bed)
Step 6.5: Get another surgical tool
Step 7: Repeat step 4-6.5 and step 4 again until operation is complete.
Step 8: Done!
