Does an anesthetic injection through non-infected tissue require SBE prophylaxis?

Anesthetic injections through non-infected tissues typically do not require antibiotic prophylaxis for subacute bacterial endocarditis (SBE). This aligns with guidelines established by organizations such as the American Heart Association, which specify that antibiotic prophylaxis is generally recommended only in specific situations involving invasive procedures that involve access to the bloodstream or in patients with particular underlying cardiac conditions.

In the case of a simple anesthetic injection into healthy tissue without any signs of infection or ongoing surgical procedures that would introduce bacteria into the bloodstream, the risk of an SBE event occurring is significantly lower. Therefore, standard practice does not necessitate antibiotic prophylaxis for such injections, affirming that it is safe to proceed without additional antibiotics in these circumstances.
