What complication can arise if tumescent anesthesia is not adequately used during thermal ablation?

The increased risk of paresthesia is a significant complication that can arise if tumescent anesthesia is not adequately utilized during thermal ablation. Tumescent anesthesia is used to create a better environment for the procedure by providing a volume of fluid that distends the tissue and facilitates the delivery of the thermal energy.

When tumescent anesthesia is insufficient, there may not be enough sedation or local analgesia to adequately numb the area being treated, leading to discomfort or pain during and after the procedure. This pain can disrupt the procedure's effectiveness and may lead to post-operative complications. Additionally, inadequate anesthesia can result in nerve irritation due to heat exposure, thus increasing the likelihood of paresthesia, which is a common issue where patients experience abnormal sensations such as tingling or numbness in the treated areas.

Proper tumescent anesthesia not only enhances patient comfort but also minimizes the risk of such complications, enabling a smoother procedure and recovery.
