We have a ketamine clinic of sorts in our VA. First VA in the country to offer it, actually. We've done nearly a thousand cases at this point without any medical events, and this in a sicker-than-average population. A poster above mentioned the prospect of a physician monitoring several cases at once, in parallel, which may be the key to profitability. We actually fill out an anesthesia record for these cases (we don't bill, but the times are used for workload tracking/staff planning purposes, so there's an Anesthesia Start and End time). We tend to hand off the cases mid-infusion to a PACU nurse so we can start the next one. Again, since we're not billing, we have just sorta kept doing it this way for efficiency. Out in the world, I wondered how it would look to have one clinician responsible for multiple patients simultaneously. From a safety perspective, I agree it would seem very safe to me to have 3-4 of these going at once; the doses are really very small. But from a regulatory standpoint, I wouldn't think you could be documenting care for them simultaneously.
