I will give first aid pointers to the best of my ability when things come up. Not sure I want to be responsible for a first aid blog or thread though...this hunting/backcountry stuff is my getaway from work also!
The important thing about first aid is usually the knowledge you have more often than the kit. I carry a very small first aid kit which is tailored to dealing with serious things and has virtually nothing that you will find in a regular kit from REI. I consider some preventative toiletries and water treatment as more important first aid (e.g. lip balm, sun protection hat, blister lube, tick tweezers on the 1 1/2 oz Leatherman, water filter or tablets, etc.). Sometimes people can do more harm than good by suturing closed dirty wounds or wounds directly over exposed bone for instance, or wounds that have been open too long before receiving care. Also, there is some art component to medicine where the general rules become more blurry. For instance, wounds on the face and scalp and in a young healthy person, which don't go beyond the fatty layer, can often be sutured successfully as a primary repair safely long after 6 hours has passed.
I am often hesitant to give people specific medical information frequently, because every situation is different, and sometimes this means only giving enough information to be dangerous over the phone or internet. I have had to take care of some fairly large wounds in the field for a time (esp. 2nd degree burns...ugh) having been with the Marines/Navy, but would rather not have done so in these more austere situations/locations had there been a choice. So, rather than give specific information for every situation, I feel like it may be more helpful to tell you what I would do in general and why if you're interested. I am always open to learning new things as well.
Generally, I do not bring sutures and would not recommend bringing sutures on a typical backcountry hunt...unless you are packing in by horse and providing the medical coverage for a larger group for an extended wilderness stay. I do not bring Quickclot type preps and so of course wouldn't recommend these either.
Also, in response to one of the comments above,generally if you are doing CPR on a backcountry hunt, you are screwed. I suppose, if someone falls off a ledge or into a river and quits breathing, needing a couple of rescue breaths followed by some brief chest compressions and warming, or gets hit by lightening, then it could come in handy, but this would be a rare situation. In situations such as these, all you can do is help the person though even if your CPR skills are a bit rusty or nonexistent...in an emergency you can't make them any worse by trying to help them breath or by stopping bleeding or by keeping them warm and comfortable. Just don't move someone with a suspected serious neck injury if at all possible.
