Abstract

Background: Using gauze soaked in lidocaine hydrochloride (2%) can induce anesthesia to suture wounds painlessly, without causing anxiety due to fear of injection in adult patients who referred to the emergency department with limb laceration. 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

Highlights

Introduction: The use of gauze soaked in lidocaine hydrochloride (2%) can painlessly induce anesthesia to suture wounds, without causing the anxiety due to fear of injection in adult patients who were admitted to the emergency department with limb laceration
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 (P ≤0.0001) Conclusion: The pain intensity after anesthesia was significantly different in the two groups and was reduced dramatically in the local anesthesia group
A total of 180 patients were included in the study, which followed a normal distribution with P value=0.079 provided by Kolmogorov-Smirnov statistical test

Summary

Introduction

The mean of pain intensity of the patients in the case group at the time of admission was 7.92 ±0.64, based on VAS. The mean of pain severity in the patients after lidocaine-impregnated gauze anesthesia was 7.54±0.91. The mean of pain severity in the patients of the control group at the time of admission was 7.82± 0.61, based on VAS. To facilitate wound healing and to reduce the pain, available anesthetic drugs, especially amino amides such as lidocaine or prilocaine, are used.[1]. These drugs can be injected into the edges of the wound or penetrated topically. The likelihood of vasoconstriction increases the duration and intensity of local anesthesia.[3]
