Another example: the medication for toothaches known as Cavit.
Cavit comes as a pre-mixed paste, or a powder you mix with clove oil. Purpose: to temporarily fill a cavity until a dentist can be seen. Problem: mostly, it’s worthless. It requires expertise to insert the pellet of goo into the cavity successfully. Which requires experience. Most captains I’ve spoken with say their initial experiences with cavit have been fails, so they never gain the expertise.
It’s not enough to know what the medication is meant for, or theoretically know how to use it. You have to actually have practice going into the spit-swilled mouth of a frightened man with a pointy object to gain the expertise to use it. I may be wrong, but most medical training classes don’t teach cavit application. Experience and expertise are not gained.
If there are captains out there with success stories. I’d like to hear them.
