Lost quibble
Dear Jack,
You are not Doctor Kildare. You really cannot perform surgery and manage the anesthetic at the same time unless you are doing the procedure under local. Trust me on this. This is the reason I have not only a job but a profession. I had four years of med school and four years of residency to enable me to take care of patients during surgery. Please don't blow me off in this fashion ever again kthx.
You contaminated yourself when you injected his 'anesthetic' into his IV. You needed to go back out and re-scrub. You've contaminated they entire surgical field and the wound and your patient will ultimately die of sepsis.
You 'anesthetized' your patient after he was prone. A situation necessitating the intubation of a prone patient is something that gives anesthesiologists nightmares (not to mention lawsuits) and yet you merely left Ben with a nasal cannula. How do you expect to secure his airway? Or, since you're planning on killing him anyway, is this a moot point? A ruse the assembled Others are too stupid to notice while dear old Ben hypoventilates his life away? Hypercarbia could be the cause of your tachycardia there, dude.
But they noticed when he got tachycardic, didn't they? Even though we both know that it wouldn't happen that quickly, between heartbeats. 'Blood loss that will kill him in an hour'? And how were you planning to replace that? Do The Others have a cell saver? They don't even appear to have suction so the answer to that is 'no'. However, since spinal tumors are often very, very bloody, the hypotension you've caused with your bloodletting might make the dissection a bit easier. Provided your patient doesn't die from hypovolemic shock, that is.
I will admit that it might barely be possible to do the procedure under spinal with sedation. The problem there is the patient would be awake, which Ben clearly wasn't, and the spinal might wear off before you're finished. Awkward that.
I am hoping that you've simulated tachycardia-via-hypovolemia with an epinephrine-containing injection. If so, good fake out and thank you for upholding your Hippocratic Oath, although you're skating pretty damned near the edge.
There's probably more to say but since I was watching through eyes battered by headache I'm going to leave the chastisement here. In short, it looked like a scene out of Veterinarian's Hospital. Do better next time, please.
luv,
scrubs
