Surgery Type: Description: (What it fixes) How to: Target Zone:
Bone Repair Surgery This surgery is used for mending broken bones and fractures. Scalpel->Hemostat->Retractor->Bone Gel->Bone Setter->Bone Gel->Cautery Everywhere besides the Eyes and Mouth.
Internal Bleeding Surgery This surgery mends the torn/ripped arteries and veins within the body to stop internal bleeding. (Note that you can use quickclot to fix internal bleeding. This saves a lot of time, but be careful since it causes brute damage and bleeding which needs bandaging.) Scalpel->Hemostat->Retractor->Fix-o-Vein->Cautery Everywhere.
Facial Reconstruction Surgery This surgery fixes the facial deformities gained from combat.i.e Unknown as Squad marine. Scalpel->Hemostat->Retractor->Cautery Mouth.
Amputation Removal of a limb or a limb stump. Bone Saw Limbs: Legs, Arms, Hands, Feet.
Limb Replacement Surgery The replacement of missing limbs with robotic ones. You can also reattach a robotic limb to just a hand or foot stump. Scalpel->Retractor->Cautery-> Now attach a robotic limb. Limbs: Legs, Arms, Hands, Feet.
Internal Organs Surgery Mending collapsed lungs and other broken organs.
  • If the patient has robotic organs replace the Trauma Kit step with Nanopaste Nanopaste (Steps in parenthesis are only necessary for chest and skull surgeries.)
Scalpel->Hemostat->Retractor->(Bone Saw->Retractor)->Advanced Trauma Kit->(Retractor->Bone-Gel->Bone-Gel)->Cautery Chest.
Eye Surgery Mending the eyes. i.e Blindness Scalpel->Retractor->Hemostat->Cautery Eyes.
Foreign Object Removal Removal of unknown objects from the body such as implants and shrapnel from bullets. (Steps in parentheses are only needed for chest and skull surgeries). Scalpel->Hemostat->Retractor->(Bone Saw->Retractor)->Hemostat->(Retractor->Bone-Gel->Bone-Gel->)Cautery Everywhere besides the Mouth and Eyes.
Alien Embryo Surgery The removal of an alien embryo. Scalpel->Hemostat->Retractor->Bone Saw->Retractor->Hemostat->Retractor->Bone-Gel->Cautery Chest.
Brain Damage Surgery Fixing up the brain. The use of fix-o-vein depends if only there is severe brain damage. Otherwise getting rid of the bone chips with the hemostat should fix it. Scalpel->Hemostat->Retractor->Bone Saw->Retractor->Hemostat->Fix-O-Vein->Retractor->Bone-Gel->Bone-Gel->Cautery Head.
Organ Removal/Transplantation Surgery Removing an organ from the body and transplanting a new organ.
  • If the patient has robotic organs replace the Trauma Kit Advanced Trauma Kit step with Nanopaste Nanopaste. (Steps in parenthesis are only required if the organ took damage during transport or transplantation into the subject.)
Scalpel->Hemostat->Retractor->Bone Saw->Retractor->Scalpel->Hemostat->New Organ->Fix-O-Vein->(Advanced Trauma Kit)->Retractor->Bone-Gel->Cautery Chest and Head.

Combining Surgeries

Very often people will come in with multiple problems at once. For instance, you might have a patient who has a fractured skull, brain damage, and shrapnel in their head. Performing three separate surgeries is very time consuming when other marines may be waiting. It is possible to condense the surgery down to one in such a manner:

  • Broken skull, brain damage, and head shrapnel removal surgery
  1. Scalpel Cut an incision while aiming with 'Help' intent at the head
  2. Hemostat Stop bleeders in the head
  3. Retractor Open up the incision for further surgery
  4. Bone Saw Cut through the skull
  5. Retractor Open up the skull
  6. Hemostat Here it gets a bit tricky, use a hemostat repeatedly to pull out bone chips and shrapnel until you get a message that nothing more can be found in the brain. Both types of removal can take several rounds or attempts.
  7. Fix-O-Vein Advanced Trauma Kit Use the FixOVein and Trauma Kit to repair hematomas and damage to the brain and eyes if necessary
  8. Use the Health Analyzer to check that the patient does not have brain damage! If the patient still has brain damage go back and use the hemostat and FixOVein more until the Analyzer shows no brain damage.
  9. Retractor Close the skull back up
  10. Bone Gel Use bone gel on the damaged bones in the skull
  11. Bone Setter Piece together the broken or fractured skull
  12. Bone Gel Add bone gel once more
  13. Cautery Seal up the incision
  14. Use the Health Analyzer again to see if the patient needs antibiotics or anti-toxins and administer them as needed

What about an infected marine with a broken chest, internal bleeding, and a ruptured lung? Here you'll want to use medication from the vendors in medbay in order to tackle the problems at hand.

  • Alien embryo removal, ruptured lung, and broken chest surgery (with a side of internal bleeding)
  1. First use one Quick-clot and one Dexalin Plus injectors to stop internal bleeding and to halt suffocation damage from the ruptured lung. While you can stop internal bleeding surgically, in the vast majority of cases a quick jab with Quick-clot is preferable. Keep a couple of Dex+ injector on hand to keep the patient from dying from the ruptured lung.
  2. Scalpel Make an incision quickly
  3. Retractor Ignore bleeders and rearrange organs. Removing the larva ASAP is the top priority right now
  4. Bone Saw Cut open the rib cage
  5. Retractor Separate the rib cage
  6. Hemostat Begin pulling out the alien embryo
  7. Advanced Trauma Kit Repair the ruptured lungs and any other damaged organs, note that a mechanical heart requires Nanopaste to fix
  8. Hemostat Now stem the bleeders with the hemostat
  9. Retractor Close up the rib cage
  10. Bone Gel One application of bone gel for the cut rib cage. Cut rib cages and skulls require one application of bone gel after they've been pushed back together.
  11. Bone Setter Set the broken bones in the chest
  12. Bone Gel An application for the set bones. In general remember that fixing a broken bone requires one application of bone gel before the setting and one after.
  13. Cautery Cauterize the incision, your patient should be recovering nicely now
  14. Again, use the Health Analyzer to double-check your work and to dispense spaceacillin or dylovene as needed

General Tips

  • Wash your hands to help reduce infection chance. A space cleaner bottle on yourself works too.
  • Anesthesia is important to successful surgery, make sure to put a mask on the patient's face, an anesthesia tank on their back, and turn their internals on.
  • If in a rush, you can give your patients ~30u of oxycodone for quick surgeries without anesthesia. You need to work quick though.
  • Patients can often times tell you where they need surgery if an advance scanner is not available.
  • Triage cases properly, alien embryo cases and lung ruptures take priority over brain damage cases which in turn take priority over simple bone fractures in limbs.
  • Internal organ damage can oftentimes be fixed with peridaxon turning some surgeries into simpler, faster bone repair surgeries.
  • Use the Health Analyzer to check for brain damage during brain surgery to confirm that you've fixed everything.
  • Use the Health Analyzer to confirm that a patient's bone fractures are all gone after performing all required bone repair surgeries.
  • Use the Health Analyzer to check for post-op infection that should be treated with spaceacillin.
  • If no other options are available, roller beds and tables can be used to perform surgery.
  • Basic Laser Scapels are available from research which are essentially faster scapels. Make sure to ask the researcher for them! An even better scapel is also available on the Planet somewhere too..
  • Infected wound detected in subject [Insert Location Here]. Disinfection of wounds recommended means that the patient has a infected wound that needs to be treated with gauze/advanced brute kit, surgery and spaceacillin won't work at all.
