All surgery requires a set of medical tools, typically found in the Operating Theatre, along with an operating table.

Surgical Tools and Alternative Procedures

Information about most tools used in surgery can be found here.
Synthetics and IPC Surgeries can be found here.

Surgery Speed and Failure

For every tool there are ghetto analogues. The percentages listed next to them show how efficient they are speed wise compared to the basic tools (on TG the percentages used to simply mean success rate until Oct 2019). For example, if it says "50%" the step takes double the time to complete. These percentages stack with the percentage point bonus or malus from using different tables or chemicals (see Beginning of any Operation).

However, the slowness is capped to 2x the original time the step would have taken. A step that takes 10 seconds would cap at 20 seconds, for example. Every second after that cap will instead add 1 percentage point into the odds of a failure. Failing may cause extra damage or other effects.

So for example:

• Say a surgery step takes 10 seconds by default, but you use a pen (25%) instead of a hemostat and do it on the floor (50%) instead of a surgery table.
• Now the surgery is slowed to 40 seconds, but since it's capped at 20 seconds it takes 20 seconds.
• Those 20 extra seconds that were removed when we capped it to 20 seconds is now your chance to fail.
• Result: The step takes 20 seconds and has a 20% chance to fail.

Beginning of any Operation

Step 1: Undress the part of the patient that needs surgery. You can do this by dragging them onto yourself, and then clicking the clothes you want to remove from them in the pop-up.

• Important: The uniform the patient is wearing usually covers both legs, arms, groin and torso. Helmets, eyewear and masks always obscure the eyes, make sure to remove them if working on the eyes.

Step 2: Place the patient onto the operating table. Do this doing a

shove a person onto the table and tell them to rest, though they might not appreciate this.

• If there is no operating table, you can use: Stasis bed (-10%), any table (-20%), any bed (-30%), ask them to lie on the floor (-50%). The speed of completing every step will be reduced.

Step 2.1 (Optional) Splash on, spray or apply a patch with Miner's Salve (+10%), Sterilizine (+20%), alcoholic drinks (up to +46%), or Honey (+60%) for faster surgery speed.

• The stronger the alcohol, the more effective! The formula is: 0.1*(booze power/65). For example: Ethanol gives +10% surgery speed, Manly Dorf +15%, Bacchus' Blessing +46%.

Step 2.2: (Optional) Use a tank of anesthetic and a breath mask to make your patient sleep. This has no surgical benefits however.

Step 3: Place drapes or bedsheet over the part of body you are operating.

• If you done step 1 wrong, it will tell you that you must remove clothing first. If you continue without fixing, you will stab your patient instead of doing surgery.

Step 4: Turn off

Do the surgery (see the steps below!). Afterwards congratulate the patient and kick them out. Failed steps will autorepeat.

To abort a surgery, hold a cautery in one hand and drapes in the other, and use the drapes on the patient.

Procedures requiring no research or computer

Organ Manipulation

This surgery covers operations to remove/insert organs (brain, heart, appendix), lizard/cat tails, cyber implants and alien embryos.
The body part to target depends on which procedure you want to do.
See below for details about each procedure.

Procedure	Ghetto Analogues
Step 1: Scalpel: make an incision.	(65%) (45%) (75%) Any other sharp item (30%)
Step 2: Retractor: retract the skin.	(45%) (35%)
Step 3 (Head/Chest only): Circular Saw: saw through bones.	(65%) (50%) (50%) (35%) (25%) (75%) Any other sharp item (20%)
Step 4: Hemostat: clamp the bleeders.	(60%) (35%) (15%)
Step 5: Scalpel: make an incision.	(65%) (45%) (75%) Any other sharp item (30%)
Step 6 Remove: Hemostat: remove something.	(55%) (35%)
Step 6 Insert: Hands: insert something.
Step 7: Cautery: seal the wound.	(90%) (70%) (45%) (20%)

Ordinary organs that require Organ Manipulation

These organs are present in every normal human, and can be removed or transferred through the Organ Manipulation surgery type.

Brain

The source of consciousness, and where the player actually resides. Removing the brain from a body will make it unrevivable through normal means. The brain can also be inserted into an MMI to allow it to speak, and to prepare it to be inserted into a Cyborg or an AI. Or it can be transferred into another body, which can then be revived.

Changelings' brains are vestigial, and they can survive without them. Beheading a changeling will not prevent one from reviving.

Target: Head

Note: Brains can also be removed by beheading the target and using a sharp object on the head to extract the brain.

Heart

Required for basic survival, removing it will cause a heart attack, dealing huge amounts of oxygen damage until a new, beating, heart is inserted, or death. This can be delayed with epinephrine, if you need more time.

On their own, hearts only beat for a short time when removed from a living body. To get a heart beating again, click on it while it's in your hand.

Heart attacks can also be induced by Initropidril, and a heart attack may continue if you insert a still heart in a patient. In either case, to restore the heart to normal functionality, the patient needs to either be defibrillated or receive an electric shock.

Target: Chest

Eyes

They're required for sight. Removing them will, obviously, turn the patient blind. Some races' eyes can see in the dark.

Target: Eyes

Ears

Required for hearing. Removing them will make the patient deaf.

Target: Head

Liver

Required for processing reagents. Removing the liver will cause the patient to take heavy toxin damage. Some starting jobs give you a liver with special benefits.

Target: Chest

Lungs

Required for breathing. Removing the lungs will cause the patient to suffocate, regardless of air or internals. Some species have mutant lungs that don't need air: transplanting them onto an breathing race will transfer this property.

Target: Chest

Stomach

Required for eating and drinking.

Target: Chest

Tongue

Affects speech. Lacking a tongue will make speech very hard to comprehend, while mutant tongues such as lizards' or flypeoples' will give the patient the race's speech quirks. Abductors' tongues carry over their telepathy, but they prevent normal speech.

Target: Mouth

Appendix

Removing it cures appendicitis and prevents it in the future, too.

Target: Groin

Other organs that require Organ Manipulation

There are also non-natural organs which can be added to give bonuses or to harm the patient in a few cases.

Cybernetic Implants

These offer benefits to the patient at the cost of being very vulnerable to EMPs, with malfunctions ranging from eye-flashing to heart attacks. Cybernetic implants always require the Organ Manipulation type surgery, even for arms. Cybernetic implants can be printed by Robotics or the medbay techfab after research.

Target: Chest/Head/Eyes/Arms

Cybernetic Organs

Cybernetic organs replace organs entirely. You need to remove the corresponding organ first to make room for the cybernetic organ. They are vulnerable to EMPs. Cybernetic organs can be printed by Robotics or the medbay techfab after research.

Target: Chest/Eyes

Xenomorph Embryo

An alien larva growing inside the patient. If not removed quickly enough, it will gib the patient and try to escape, growing into a dangerous Xenomorph.

Target: Chest

Romerol Tumor

A latent infection in the patient's head, caused by Romerol. If the patient dies while affected by Romerol, he will eventually rise as an aggressive Zombie. This will repeat as long as the infection lasts; removing it surgically, cutting the head off, or gibbing the corpse will prevent resurrection.

Romerol is infective, and anyone hit by a zombie while unprotected will also acquire a Romerol Tumor.

Target: Head

Prosthesis Organ Manipulation

Augmented limbs have special surgery steps for Organ Manipulation that are completed with mechanical tools. Unlike all other procedures, this can be performed on yourself with self-surgery.

Target: Head, chest, groin, arms

Procedure	Ghetto Analogues
Step 1: Screwdriver: unscrew the shell.	(75%) (50%) Any other sharp item (30%)
Step 2: Hands: open the hatch.

Step 4: Multitool: prepare electronics.	(10%)
Step 5: Hemostat: manipulate organs/remove implant.	(65%)
Step 6: Wrench (chest and head only): wrench the bolts.	(10%)
Step 7: Screwdriver: screw the shell.	(75%) (50%) Any other sharp item (30%)

Alien Organ Manipulation

Used to remove or add organs from Xenos.

Step 5 Remove: Hemostat: remove something.	(55%)
Step 5 Insert: Hands: Insert something.
Step 6: Cautery: seal the wound.	(90%) (70%) (45%) (20%)

Lobectomy

This surgery is an extended organ manipulation, cutting open the chest cavity and removing a disfunctional lobe within the lungs. This restores health to the lungs, and makes them operable, if they weren't before. Be warned, however, that this surgery can only be done once per set of lungs. Can only be performed if the patient's lungs are above 60 damage, which is a tad past severe damage thresholds. Do NOT confuse this surgery with lobotomy!

Target: Chest

Procedure	Ghetto Analogues
Step 1: Scalpel: make an incision.	(65%) (45%) (75%) Any other sharp item (30%)

Step 5: Scalpel: excise the damage lung node. (95%)	(45%) (45%) (25%)
Step 6: Cautery: seal the wound.	(90%) (70%) (45%) (20%)

Coronary Bypass

This surgery is an extended organ manipulation, cutting open the chest cavity and grafting a bypass onto the patient's heart. This restores health to the heart, and makes it operable, if it was not before. Be warned, however, that this surgery can only be done once per heart, and that incising the heart and attaching the graft are not guaranteed successes. Keep bandages on hand in the event of failing the step, which will result in massive amounts of bleeding. Can only be performed if the heart has more than 60 damage (tad past severe damage threshold).

Target: Chest

Step 6 Hemostat: attach heart graft. (90%)	(35%) (15%) (5%)
Step 7: Cautery: seal the wound.	(90%) (70%) (45%) (20%)

Hepatectomy

Removes damaged parts of the liver so that the liver may regenerate properly. A liver healing surgery, similar to Coronary Bypass and Lobectomy. This liver surgery only shows up as an option when liver damage is above 50 and the liver itself is not failing.

Target: Chest

Procedure	Ghetto Analogues
Step 1: Scalpel: make an incision.	(65%) (45%) (75%) Any other sharp item (30%)
Step 2: Retractor: retract the skin.	(45%) (35%)

Step 5: Scalpel: incise. (90%)	(45%) (45%) (25%)
Step 6: Scalpel: remove damaged liver section. (95%)	(65%) (45%) (35%)
Step 7: Cautery: seal the wound.	(90%) (70%) (45%) (20%)

Failing the last scalpel step will deal damage to the liver.

Gastrectomy

Removes a piece of your duodenum, attaching your stomach back to your lower intestines. A stomach healing surgery, similar to Coronary Bypass, Lobectomy and Hepatectomy. This surgery will appear only if your stomach has at least 50 damage, and will help you be able to digest food again without disgust.

Upgradable Surgery

These surgeries are available roundstart but can be upgraded to better or different versions by researching certain nodes and then syncing a connected operating computer.

Tend Wounds

The tend wounds surgeries all share the same steps. They can be upgraded by researching certain nodes, and then syncing the operating computer with research database. There are "bruises", "burn" and "Mixture" versions. By default only "bruises" and "burn" are available. The basic versions of this surgery can be performed anywhere, but the upgraded versions require an operating table with an adjacent and synced operating computer.

The target is healed by this surgery, without any chemicals being involved. Useful for healing dead bodies for revival. This works on patients with clothes on, but it's only 55% as effective.

Target: Chest

Procedure	Ghetto Analogues
Step 1: Scalpel: make a careful incision (does not cause damage or bleeding).	(65%) (45%) (75%) Any other sharp item (30%)
Step 2: Hemostat: repair damage to the target (automatically repeats until fully healed).	(65%) (55%)
Step 3: Cautery: seal the wound.	(90%) (70%) (45%) (20%)

• Step 2 will heal at least 5 damage each time it's repeated, with an added bonus the more damaged the patient is. This the bonus healing becomes higher with higher tiers of research, ranging from (patient's damage / 75) to (patient's damage / 12.5). The bonus is much lower on dead patients.
• Without any research the heal is 5 damage plus a bonus from damage. ("bruises" and "burn" versions only).
• With Improved Wound-Tending Surgery researched and synced, it will heal 5 damage plus a higher bonus from damage ("bruises" and "burn" versions only).
• With Advanced Surgery researched and synced, it will heal 5 damage plus an even higher bonus from damage ("bruises" and "burn" versions only).
• With Advanced Surgery researched and synced, you'll be able to do the "mixture" version (tend physical wounds), which heals 3 brute and burn plus a bonus from damage, but the step takes much shorter time than the other two versions.
• With Experimental Surgery researched and synced, "tend physical wounds" will heal 3 brute and burn plus a better bonus from damage.
• With Alien Surgery researched and synced, "tend physical wounds" will heal 1 brute and burn plus a very high bonus from damage.
• Failing the hemostat step will deal some of the damage it would have healed.
• You can hold a Health Analyzer in your other hand to see your patient's remaining wounds while treating them.

If research was completed in the middle of surgery, you must restart the surgery to get the upgraded version.

Advanced Surgery
