The setting is the year 2020, and the character is a genetically engineered human with an amped up metabolism and immune system (and if that doesn't give away the fandom, nothing will).
The situation is this: he's had a kidney traumatically removed, and was awake for the entire procedure (paralyzed but not unconscious). The people who performed the surgery aren't the greatest when it comes to sanitation and sterilization, and afterward they put him in a damp, filthy basement with just a bandage over the roughly stitched incision and no antibiotics. They also have the means to completely disable his super-immune system, leaving him weak and more susceptible to infection than a normal human. He's found in the basement at some point up to 24 hours later.
Firstly, how exactly would I describe the amount of pain involved in the procedure itself? I've known people before whose anesthesia was messed up for minor surgery, and they've told me what it felt like, but am I correct in thinking there's going to be a difference between minor leg surgery and major invasive abdominal surgery?
Second, would sepsis have set in by the time he's found? What kinds of issues would he be looking at with the combination blood loss/kidney loss/infection? Could his other kidney begin to fail, or would that take longer than 24 hours? Assuming a major septic infection and a compromised immune system, what's the absolute longest he could survive with antibiotics?
I do have the unfair advantage of being able to turn his immune system back on whenever I want/need to, and once I do that he's pretty well guaranteed to survive, so basically what I'm trying to figure out is just how sick I can get him before I absolutely have to make him better.
Google searches have included: sepsis, septicemia, kidney removal surgery, traumatic nephrectomy, renal failure, and surgery without anesthesia.
Thanks tons in advance for anyone who can help me out.
