Gas is very expensive. Use as little as possible. Low fresh-gas flows, etc. Do a spinal or regional block for everything you can. Hysterectomy? Spinal. Bowel case? Spinal. Anything urologic? Spinal.
I'm not sure how embellished this story is, but I was taught by a guy who went to a very poor area of Africa many years ago to teach a handful of nurses how to perform anaesthesia. I think the country had one anaesthetist (I think from Europe?) in the capital city; but if you didn't live near the cIpital then you were **** out of luck. In the rural regions the medical practices were proper bush medicine and some bigger cities had some physicians/nurses, but traditional healers were the core providers. If you needed a section or emergency surgery you were in deep trouble.
So my mentor fellow went over to teach some nurses how to give an anaesthetic. The idea was they could have a handful of nurses in these non-capital cities who could do the airway/spinal while the main physician/nurse did the other stuff. It was to open up these regions to visiting international surgeons to do very low-risk procedures, which had previously been restricted to the capital.
The stories he told were ridiculous. He had to teach a select number of "the best of the best" nurses how to give a safe anaesthetic in places that might not even have reliable electricity in something like 10 weeks. The nurses were selected from returning nationals who got the best score in nursing school in a nearby country (this country had no medical/nursing school and was colonised by the French). The returnees were given an outdated copy of Miller's to prepare some 3-4 months prior to the hands-on process. When he arrived he found out that not all of them could read English particularly well as their nursing school had been in French... So half of them had been learning English while reading Miller's in the space of a few months.
Resources out rural were zero. Regional or bust. No monitoring, nothing. I think they had an abundance of pethidine or similar that some altruistic hospital had shipped to them a year or so ago because it was about to expire (it was all out of date now).
Some of his students ended up being the teachers of the next generation and he'd impressed something about high-spinals onto them, because through their chinese-whisper teaching strategy over the years their treatment for anything unusual (loss of consciousness/dizzy/N+V/confusion/whatever) had evolved into placing the patient steep head-up. Any deaths were chalked up to an extreme rate of "high spinals."
An O+G surgeon went to the same country to do some humanitarian work some years later. They refused to ever do humanitarian work again after seeing the absurd mortality rate during sections in that country. I think they did CPR 4 times in their first week with 1 death on the table and 2 tubed in their brand new ICU with significant neurological deficits. O+G doc tried appealing to them re: brain perfusion in steep head-up and what the most likely cause of these patients significant haemodynamic collapse had been (rarity of pressors there at that time). They were told it was just a case of 4 high spinals...
Careful what you teach people over there!
