Effect of lidocaine spray on the pain intensity during insertion of vascular needles in hemodialysis patients

Pain during insertion of vascular needles is the most stressful part of the hemodialysis treatment. Repeated painful interventions have adverse effects on the body and the spirit of these patients. Due to central role of nurses in care, they have important role in reducing the pain of these patients. This study was conducted to determine the effect of lidocaine spray on the pain intensity when the needles are inserted into vascular access for hemodialysis. A semi-experimental and double blind study was performed on 30 patients in hemodialysis ward of Semnan Fatemieh hospital. In this study, pain intensity during the insertion of hemodialysis vascular needles was measured by numerical pain scale in a one group by using Lidocaine spray and Lidocaine spray placebo. Pair T test was used to determine pain intensity mean difference between two conditions. Overall, the results showed that the mean pain intensity was 2.3±1.91 and 3.96±2.14 in two conditions using lidocaine spray and lidocaine spray placebo, respectively. However, a significant difference was found between the mean pain intensity in two conditions statistically by using paired t- test (P<0.001). Results showed that lidocaine spray is effective in reducing pain when the needles are inserted into vascular access. Therefore, based on the results of the study, it is recommended to use lidocaine spray in order to reduce pain in these patients before insertion of hemodialysis vascular needles
