" Comparing the Effect of Using Lidocaine Spray and ShotBlocker on Pain Level during Intramuscular Injection: A Randomized Control Trial"

Abstract

Background: Intramuscular injection is a common nursing practice in clinical settings. Although their therapeutic advantages, but can also cause pain in patients. It is necessary to reduce pain caused by intramuscular injection. The aim of this study was to comparing the effect of using lidocaine spray and shotblocker on pain level during intramuscular injection.
Methods: A randomized controlled trial was conducted in emergency department at Imam Al-Sadiq General Hospital in AL-Hilla city, during a period between December, 2023 to June, 2024. Data were collected through interviewing using the visual analog scale, scio-demographics and medical data. The researcher uses a simple random sample where patients choose a color from a sealed envelope consisting of three colors. 150 patients who receive diclofenac sodium, divided into three groups, 50 in each of the lidocaine, shotblocker and control groups. Both a descriptive statistical analysis such as (frequencies, percent, standard deviation and mean of score) and inferential statistical analysis such as (independent Sample t-test, analysis of variance, post Hoc testes and Eta Square). The significant level at p-value < 0.05.
Results: There are statistically significant differences in pain scores among ShotBlocker, lidocaine and control groups (p = .000). The ShotBlocker group compared to the lidocaine group (mean difference of -1.18, p=.000), and the control group (mean difference of -3.92, p=.000). The lidocaine group compared to the ShotBlocker group (mean difference of 1.18, p .000), and the control group (mean difference of -2.74, p = .000). The control compared to the lidocaine group (mean difference of 2.74, p =.000), and the ShotBlocker group (mean difference of 3.92, p =.000).
Conclusions: The application of ShotBlocker and lidocaine showed effectiveness pain reduction during intramuscular injection but ShotBlocker was more effective.
Recommendations: Using ShotBlocker as an effective non-pharmacological method to reduce pain during intramuscular injection.
