Which local anesthetic is preferred for patients with liver impairment?

The preferred local anesthetic for patients with liver impairment is Mepivacaine. This is due to its unique metabolic pathway, which minimizes the burden on liver function. Mepivacaine is metabolized primarily by the kidneys rather than the liver, making it a safer choice for individuals with liver issues.

In terms of the other options, Lidocaine and Bupivacaine are both metabolized in the liver, which can pose a risk for patients with compromised liver function because their elimination from the body can be impaired. Articaine, while it does have some advantages, is also metabolized partially in the liver and could introduce complications in patients with liver impairment. Thus, Mepivacaine’s renal metabolism makes it the most suitable option among the local anesthetics listed for patients with liver problems.
