Methods: This is a triple-blind interventional study in which trauma patients with limb wounds enter the study. Distilled water impregnated gauze will be used for the control group and 2% lidocaine impregnated gauze will be used for the intervention group. The gauze will be placed on the wound for 5 minutes. The pain will be assessed with VAS. Results: A total of 180 people were enrolled in the study, which followed a normal distribution (Pv = 0.079) by Kolmogorov-Smirnov statistical test. The mean age of the participants is 32.02± 13.97 years. The pain intensity of patients in the case group based on VAS at the time of admission was 7.92 ±0.64. The severity of pain in patients after lidocaine-impregnated gauze anesthesia is 7.54±0.91. The severity of pain in patients based on VAS at the time of admission was 7.82± 0.61. The severity of patients' pain after anesthesia with lidocaine-impregnated gauze was 3.51±1.51. In the case group, the topical injection of lidocaine was repeated for anesthesia for all patients, while in the control group, the injection was repeated only for 3 patients. Pv≤0.0001) Conclusion: the pain intensity after anesthesia is significantly different and in the anesthesia group with local the injection has dropped dramatically
