Can anyone with professional experience tell me what the best emergency wound packing material is? I am thinking in terms of a material that won't leave any fibers behind when removed. There must be a best practice type of gauze or something that can be used to that effect. I saw some wound packing gauze that comes in small plastic bottles, but I don't think that is for bloodstopping on larger deeper wounds, but I could be wrong. I know about QC Combat Gauze but I am trying to find something that has no expiration date.
