I read the article, and while it seems good it's a little outside of my area of expertise. However, as it was written by a former Ranger PA who's now in med school, it seems credible enough to post.
The MARCH algorithm is synonymous with Tactical Combat Casualty Care (TCCC). It is a simple acronym for remembering the necessary steps in priority for saving lives in combat. M-massive hemorrhage, A-airway, R-respiratory, C-circulation, and H-hypothermia.
...It is fantastic to see programs like TCCC and its associated methods (MARCH) making their way into civilian medicine and EMS. I know the author was well intentioned and wanted to share a great way to approach the trauma patient. It seems he was trying to take some standard EMS trauma care knowledge, apply the concept of MARCH, in order to improve on the current approach. I truly appreciate his efforts. However, there should be an understanding of why the point of injury care/battlefield medicine protocols are written in such a way and the evidence that supports it.
