I'll stick to what I know. Anesthesia. There are plenty of my colleagues that have never operated on a generator run OR, with an oxygen concentrator, without an aline, limited blood, truly dependent on surgical blocks, having to truly triage, and function as the ER and ICU, and experienced a real mascal. And to be willing to do it day after day after day. Those that have are the exception and should be really valued. Most have zero interest in that. Anesthesia is going to be a real problem.
I disagree (also an anesthesiologist).
All I can tell you is what I experienced and observed deployed to the busy and well-equipped Role III in Kandahar, and deployed as OIC of a FRSS with just about a dozen people and a couple tents and no other real support.
I graduated from an inservice residency that was solid (albeit dependent upon out-rotations at civilian hospitals) but it had no trauma experience. I had to count elderly hip fractures as "trauma" to get my numbers to graduate, it was that low. Then I went to a small command where I was 1 of 1 + 3 CRNAs and did outpatient stuff for 3 years while moonlighting locally for some sicker/complex patients. No trauma though.
Then I went to Kandahar and the anesthesia was ... easy. Trauma is easy. Access, tube, blood. Maybe some regional. Out the door hours later.
I was one of four US active duty anesthesiologists. We also had one Navy reservist anesthesiologist (essentially a civilian deploying from an academic hospital), and one Australian anesthesiologist (who practiced at a civilian hospital). We all did just fine from day 1.
The truth is that nobody in the military is getting any meaningful trauma experience. Certainly nobody in the entirety of the USA (military or civilian) is getting experience with the kind of combat trauma seen in theater. For all the hype over civilian trauma center gun & knife clubs, it's all handguns and MVAs and falls ... absolutely none of the high velocity rifle wounds or dirt-encrusted blast amputations seen in combat zones. But it doesn't matter, because trauma is easy. Any good anesthesiologist can do it, and do it well.
The difficulty of working in an austere environment is also overblown. Doctors are smart people. They can adapt. At my current job, we do ERCPs in a GI suite with a propofol TIVA, endotracheal tube + Mapleson circuit + wall O2. It might as well be in a tent. Lots of non-OR anesthesia is done without a machine or the usual stuff.
The FRSS I was deployed with had some equipment issues. The oxygen generators were not real reliable and getting FiO2 over 60-70% from them wasn't always possible. The compressor to refill the (tiny) tanks we had didn't always work. But that doesn't make the anesthetic
harder - you just make do. It's odd to think that a civilian anesthesiologist would struggle with that.
What makes a good trauma anesthesiologist in
any locale is the same thing that makes a good anesthesiologist: experience. Lots of cases, lots of sick patients, lots of big surgeries. Me being a USUHS grad who went to Kerkesner and C4 and NTTC wasn't what equipped me to do well with combat trauma. Me being a prolific moonlighter to double or triple my case load, plus do bigger cases with sicker patients that weren't coming to the Navy hospital - that was the real factor.
And I'm not a surgeon, but I'd rather see a busy civilian vascular surgeon in a combat Role 2 or Role 3 than an active duty vascular surgeon who maybe does a 5 or 6 cases per month.
