Treatment for such injuries is based on cold water compresses and oral analgesics (dipyrone is the rule, but the use of potent analgesics, such as tramadol hydrochloride may be required). When painkillers do not control the pain, nerve anesthetic blockade (lidocaine 4.0 mL for adults) may be employed [1–4]. Based on our past experience, we suggest using serial application of topical commercial anesthetics with 0.25% lidocaine and 0.25% prilocaine in order to greatly decrease or eliminate the pain, these drugs take effect in about half an hour and last for several hours [1, 4]. They are easy to apply, does not interfere with the approach adopted for this kind of accident, and it is especially useful for children and patients whose lesion sites do not allow blockades.
