What percentage of lidocaine is typically found in tumescent anesthesia solutions?

In tumescent anesthesia solutions, the concentration of lidocaine typically found is either 0.05% or 0.1%. These low concentrations are specifically chosen to minimize systemic effects while providing effective local anesthesia, especially for procedures like liposuction and other dermatological surgeries. The lower percentage helps to ensure that the patient experiences minimal pain during the procedure, while still allowing for a significant volume of fluid to be administered, which aids in tissue distension and hemostasis. The choice of concentration is critical to achieving the intended anesthetic effect whilst maintaining patient safety.
