A 28-year-old woman presents for diagnostic laparoscopy for pelvic pain. During laparoscopy, the surgeon announces that she intends to proceed to hysterectomy for multiple uterine myomata. The anesthesiologist then declares that he will "wake the patient up" rather than allow the surgeon to proceed, due to lack of consent for the procedure, and questionable medical necessity.

Can the anesthesiologist "tell" the surgeon what to do?
Who is in charge when two physicians on the team disagree?

An otherwise healthy 54-year-old man presents for radical retropubic prostatectomy, and expresses interest to his anesthesiologist in having postoperative epidural narcotic pain management. The anesthesiologist believes it provides superior pain control, but is informed by the surgeon that the patient "is not to have an epidural."

Is the anesthesiologist obliged to "take an order" from the surgeon? 
Should the anesthesiologist provide the anesthetic he feels is best, regardless of the surgeon's input?

A 55-year-old man has a 3-month history of chest pain and fainting spells. You feel his symptoms merit cardiac catheterization. You explain the risks and potential benefits to him, and include your assessment of his likely prognosis without the intervention. He is able to demonstrate that he understands all of this, but refuses the intervention.

Can he do that, legally? Should you leave it at that?

A 64-year-old woman with MS is hospitalized. The team feels she may need to be placed on a feeding tube soon to assure adequate nourishment. They ask the patient about this in the morning and she agrees. However, in the evening (before the tube has been placed), the patient becomes disoriented and seems confused about her decision to have the feeding tube placed. She tells the team she doesn't want it in. They revisit the question in the morning, when the patient is again lucid. Unable to recall her state of mind from the previous evening, the patient again agrees to the procedure.

One of your clinic patients is a 35-year-old man with AIDS on Medicare who is an active intravenous drug user. He uses heroin and cocaine, but he never shares needles and is reliably present at all his clinic visits. He admits that he is often unable to take his medicines regularly when he is using drugs. He is asking about antiretroviral therapy with protease inhibitors. You have just read that HIV viral resistance to protease inhibitors occurs rapidly when patients are unable to take their medicines reliably.

Should you prescribe protease inhibitors to this patient?

Your patient with cryptococcal meningitis eventually agrees to be tested for HIV and her test comes back positive. Due to her opportunistic infection she receives the diagnosis of AIDS.

Should she be reported to the department of public health?
