Dan, sounds like a rough few days. I, like her docs, am at a loss. They did all the right things. They gave her stress steroid doses for the perioperative period. A taper is not typical when she had been off regular steroids for a prolonged period. Many surgeons are now of the opinion that the covering steroids during surgery are not necessary and are "overkill" to prevent the rare adrenal insufficiency up to a year after stopping them. But, her surgeon did give them. I certainly had covering steroids during surgery within the first year, and I felt that the benefit outweighed any minimal potential risk.
I think that the fever was sort of a red herring, since it pointed them toward the notion of sepsis, especially since it continued to rise. In all likelihood, it was a separate issue. Like you mentioned before, it may well be her innate reaction to surgery.
But, when she crashed while all the while there was no evidence of sepsis, adrenal insufficiency is a good suspect. However, the crash scenario with sepsis is similar and they often give steroids for septic shock.
So, I think the jury is still out on this. I also think it is an excellent idea to bring in the endocrine specialist to consult.
The problem is that physiology is so complex that there are any number of things that go wrong to set you on a course of rapid decline. It is not always easy to figure out what set the cascade in motion. Often, the treatment is the same regardless.
You guys have my sympathies. I know exactly what that percutaneous drainage with fluoroscopic guidance is like. Even nearly 2 decades later I remember it like it was yesterday. They had to go in twice because they said my fascia was "extra tough" and would not puncture with the larger drain. I did have an abscess (about the size of a grapefruit), so it was quite tender in there.
The adrenals are interesting glands and they do not react the same in all of us. They are mediated by the pituitary, and it is difficult to tell if you are suppressed, since it does not become apparent until you are under serious stress, like the trauma of surgery. It is not uncommon for individual patients not to follow the rule book!
