During residency, rotated at hospital which exclusively treated cancer patients. Breast surgeons were very busy, high volume. 2 that I can recall were insistent that anything short of a mastectomy or reconstruction should be a ‘Mac case’. From us, it meant putting patients under proposal getting about 150-200 mcg/kg/min and face mask, that’s it. I didn’t like it because these cases could take two to three hours, and if patient obstructed and jaw thrust wasn’t effective then I would place an oral airway. Lots of obese patients with MP3-4 and shi**y neck extension. I figure that if they aren’t responding to surgical stimuli, then they likely have a wide open LES and abolished airway protective reflexes, not an ideal situation. Even an LMA could questionably serve to block some of what may be aspirated, definitely better than nothing.
If I brought it up, the surgeons would say they don’t want the patients nauseous and that the ‘Mac anesthesia prevented this’ as opposed to gas. The anesthesia attendings were all hospital employed, so If I told the surgeons that it’s still a general case at time out, I would get smirks from everyone in the room and corrected that my attendings call it MAC so it’s MAC. If they saw any airway device they assumed we were using gas and freaked.
Ideally, I feel the risks are minimized with use of a supraglottic device like the igel while using that level of propofol. But my attending would just mutter and walk off. ‘Don’t rock the boat’.
Also, I have noticed that for younger patients, it does not reliably prevent response to stimulation even with large initial bolus doses and it’s a fine plane between a good IV propofol anesthetic and apnea. Bad situation to tube the patient midway through a case.
