Abstract
Background of the study: Most of the patients bitten by centipedes see the doctor about the pain resulting from the centipede venom. At present, treatment for centipede bites is administered as pain relievers given orally or as muscular or venous injections, cold and warm compresses, and infiltrate local anesthetic into the wound area. Nowadays, anesthetic in forms of spray primarily designed for mucous membranes has been experimented to relieve pain on human skin in many studies and the results have been found to be effective. This study compared the effectiveness between applying lidocaine spray and using local lidocaine injection to reduce pain from centipede bites.
Materials and methods: This study was conducted as a prospective and observational study and was a quasi-experiment in patients aged 18 years old and over visiting the Emergency Department at Somdejprajaotaksin Maharaj Hospital from centipede bites during the period from 1 June 2020 to 31 August 2020 with a total of 52 cases using simple random sampling by assigning the sample into 2 groups using the questionnaire. The first group were patients treated with lidocaine spray on the wound area while the other group were treated using local lidocaine injection. The effectiveness was measured by the evaluation of pain scores before the treatment and 15 minutes after the treatment using a numeric rating scale and the Wong-Baker Faces Pain Rating Scale.
Results: The means of the pain scores that changed after the treatment of lidocaine spray and local lidocaine injection were 4.38 ± 1.52 and 4.35 ± 1.62. Using the independent t-test, it was found that the effectiveness of treating centipede bites between applying lidocaine spray and using local lidocaine injection was not different at p > 0.05. In addition, based on the paired t-test, both the use of lidocaine spray and the local injection of lidocaine could reduce the pain of patients receiving treatment at p < 0.05.
Conclusion: Treating patients with lidocaine spray and injecting lidocaine in or around the wound can reduce pain similarly. Nonetheless, spraying lidocaine is an easy option to do with less suffering from treatment for patients and fewer costs of treatment. Using lidocaine spray, therefore, can be used in primary medical treatment while waiting to see the doctor.
