==Germs and Field Surgery==
Unlike the shipside facilities where you can prevent nearly all infections by simply washing your hands.  Surgery on a roller bed or table has a significant chance of necrosis if steps aren’t taken to reduce the risk.  Necrosis causes constant toxin damage and should be avoided if at all possible.  Necrosis happens at 800 germs in a body part or organ.  As long as your patient stays below that level you are fine. Necrosis is calculated independently for each body part and each organ, so if you have 400 germs in the chest and 200 each in each arm, there won’t be necrosis.  Organs track their own germ level independently of the body part they are a member of, however they often mirror each other unless Sterilizine is used.

===Items that can reduce the risk of infection===
*Latex Gloves*
*Surgical Masks*
*Surgical Apron*
*Roller Bed - Add 75 germs per step
*Tables - Add 100 germs per step
*Sterilizine
**Removes germs based on a complicated calculation.  Two spritz will nearly clear out the germ level of anyone it’s sprayed on.  If sprayed on you it will reduce your personal germ level and thus the contribution that is mitigated through the gloves/mask/apron.  If sprayed on the patient it will reduce their current germ level and thus allow you to do more steps.  
**Sterilizine will NOT reduce the level of germs in organs, if you have a patient who needs multiple things fixed for the same body part you should either predose them with >25u of Spacecillin or only fix one thing per surgery.  Note that doing the latter drastically increases the number of steps you need to do and thus increases the risk of injury to the patient from failed steps.
*Spacecillin - If there’s >25u in them they cannot get necrosis, regardless of their germ level
*The Cautery tool - Every time you finish a surgery with a cautery it resets the germ level for that limb and all organs in that limb to 0
(*)note that with gloves, mask and apron, your personal contribution to the germ level of the patient is near zero and almost all germ contribution comes from the bed/table and their starting germ level

===Items/Actions that increase the risk of infection===
*Not wearing gloves/mask/apron
*Working on the ground or on a table
*Using ghetto tools which waste steps
*Moving around.  The less you move after getting clean the fewer germs your body collects.  Assume your patient comes to you with ~200 germs on all body parts unless you sterilize them before you start.  Standing still still results in you having 120 germs thanks to ambient levels.
*Screwing up steps DO NOT contribute additional germs over and above what would normally happen for that step, however it does waste a step which you are required to re-do and thus the redone step will contribute at least 75 germs.

===Sterilizine is your friend===
Since Sterilizine can mostly reset the germ level with 2 spritz, other than the proper surgical tools and the roller bed, it is probably your most vital item to have with you.  A spray bottle with 50 units of space cleaner and 200 units of Sterilizine will cover you for almost any round.  Sterilizine will NOT reduce the germ level of organs, it only affects the germ level of limbs.

===Spacecillin is your friend===
25u of Spacecillin will prevent all necrosis no matter how high the germ number gets.  Predose the patient with ~30u of Spacecillin if there are multiple things wrong in the same body part and you’ll be fixing them in the same surgery, or if the surgery is more complex than just fixing bones.

===Infection Summary===
Basically assume anyone coming to you has ~200 germs to start with on all body parts from their movement unless you spritz them a couple of times with Sterilizine.  Wearing gloves/masks/aprons reduces your personal contribution of germs to them to nearly, but not quite, zero.  Roller beds contribute 75 germs per step.  800 germs starts necrosis unless they have at least 25u of spacecillin them.

Basically on a roller bed you can assume slightly less than 8 steps per body part before infection thanks to the starting germ level and your non-zero contribution from your own body's germs and the roller bed.  If you spritz them twice before starting surgery you can get ~10 steps in each body part without risking infection.  If the patient only has broken bones spritz them with sterilizine, otherwise pre-dose them with ~30u of Spacecillin.
