Background and Goal of Study: Tumescent Local Anaesthesia (TLA) is a technique consisting of subcutaneous infiltration of large volumes of a dilute local anaesthetic solution, usually lidocaine with epinephrine, producing surgical area tumescence (swelling and firmness). It permits surgical procedures to be performed with less pain and less blood loss. TLA was described in 1987 by Klein for liposuction. Since then, TLA has been widely used in several surgical fields. TLA is a concern for anesthesiologists, as the recommended maximum doses of local anaesthetic are largely surpassed by the surgeon, reaching doses of 55 mg/kg of lidocaine, exceeding the defined limit of 7 mg/kg.1 The anaesthesiology literature on this topic is scarce. This review study aims to assess the safety evidence of TLA regarding local anaesthetic dosage.Materials and Methods: A literature review was conducted using PubMed database, with no publications date restrictions, using the keywords tumescence, lidocaine and dosage.Results and Discussion: 13 articles were identified, 4 published in the last 5 years. TLA advantages include performance of the procedure without general anaesthesia, reduction in blood loss and efficacious and extended postoperative analgesia. Overall, maximum safe doses of lidocaine are not consensual, varying from 28 to 55 mg/Kg, according to the solution used, addition of epinephrine and possible association with liposuction. Since lidocaine absorption is very slow in this technique it is rarely associated with neurologic or cardiac toxicity. However, the peak of absorption of the anaesthetic solution occurs after 4 to 12 hours of infiltration, and the absorption continues beyond 24 hours, requiring rigorous vigilance of the patient in the immediate postoperative period. In addition, epinephrine toxicity can also occur.1-3Conclusion: In conclusion, TLA can be considered a safe alternative or combined technique of anaesthesia and analgesia in certain procedures. To maximize safety, all anesthesiologists should be aware of the pharmacokinetics and toxicity of tumescent lidocaine, in order to recognize and treat potential complications.
