Final answer:
The standard concentration of epinephrine for LA blocks is 1:100,000 to 1:200,000. Maverick recommendations are alternative concentrations that should only be followed if supported by evidence and expertise.
Step-by-step explanation:
The standard concentration of epinephrine (epi) for local anesthesia (LA) blocks typically ranges from 1:100,000 to 1:200,000. This means that the concentration of epinephrine in the anesthetic solution is 1 part epinephrine to 100,000 or 200,000 parts of the solution, respectively. The purpose of adding epinephrine to LA blocks is to prolong the effect of the anesthetic and minimize bleeding.
Maverick recommendations, on the other hand, refer to non-standard or alternative concentrations of epinephrine that may be recommended by certain clinicians or practices. These recommendations may deviate from the standard concentrations and should be followed only if they are supported by scientific evidence and the clinician's expertise.
