[Tumescent anesthesia in dermatologic surgery].

Tumescent anesthesia is a local anesthetic technique that consists of the infiltration of a large volume of solution with a low concentration of the local anesthetic agent and epinephrine. Its main advantages are that it achieves adequate anesthesia and a significant reduction in intraoperative and postoperative bleeding, leading to greater ease of surgery with the added benefit that it facilitates tissue dissection. This technique can be used safely for anesthesia of large areas, given that systemic absorption of the local anesthetic and vasoconstrictor agent is limited, reducing the incidence of systemic side effects. The simplicity and numerous applications and benefits of this technique make it very useful in current dermatologic surgical practice.
