Background:
When snake breeders are bitten by rare snakes, deciding whether to administer snake antivenom can be challenging.
Case Presentation:
A 50-year-old man was bitten on the right finger by Boiruna maculata. The next day, his right upper limb exhibited pronounced local manifestations of envenomation. At the first consultation, a dark purple bleeding spot and a necrotic site were present under the fang marks at the bitten finger and his affected limb showed extensive swelling and redness. Snake antivenom was not administered because it was difficult to identify the snake and obtain the antivenom. We performed the pressure immobilization technique to his limb. The patient's symptoms peaked in severity on the second day of illness. He was discharged with marked improvement.
Conclusions:
We have experienced a case of snakebite envenomation by Boiruna maculata.

Local Anesthetics: Mechanism of Action
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
