In this study, we aimed to evaluate the effect of administering lidocaine as a local anesthetic at the puncture site prior cannulation on reduction of pain during intravenous cannulation (IVC).
A total of 77 patients were divided into two groups as the patients who received a local anesthetic prior IVC procedure ( = 40) and the control group ( = 37). Patients' demographic data, including age, gender, height, weight and body mass index, IV gauge, IV site, heart rate (HR), and oxygen saturation (SpO) were recorded and analyzed. Patients in both groups scored the pain they felt during IVC through the visual analog scale (VAS) and the verbal descriptor scale (VDS).
No statistically significant difference was found between the two groups in terms of the demographic features. There was no significant difference between the two groups in terms of the cannula gauges and site of IVC. The mean post-IVC HR value was statistically significantly higher compared to pre-IVC in the control group ( = 0.032), while no difference was found between the mean pre- and postprocedure HR in the lidocaine group. The mean VAS score was significantly lower in the lidocaine group compared to the control group ( < 0.001). There was a significant difference between the groups in terms of the current VDSs. The rate of the patients reporting mild pain was statistically significantly higher in the lidocaine group compared to the control subjects ( < 0.001).
According to the results of this study, lidocaine HCL-impregnated padded dressing prior IV cannulation significantly reduced pain sensation during IVC.
本研究旨在评估在静脉穿刺部位预先给予利多卡因局麻药对减轻静脉穿刺（IVC）疼痛的效果。
将 77 例患者分为两组，一组在 IVC 术前给予局部麻醉（n = 40），另一组为对照组（n = 37）。记录和分析患者的人口统计学数据，包括年龄、性别、身高、体重和体重指数、IV 规、IV 部位、心率（HR）和血氧饱和度（SpO）。两组患者均通过视觉模拟评分（VAS）和口头描述评分（VDS）对 IVC 过程中的疼痛进行评分。
两组患者的人口统计学特征无统计学差异。两组患者的套管规和 IV 部位无统计学差异。与 IVC 前相比，对照组的 IVC 后 HR 值明显升高（ = 0.032），而利多卡因组的 HR 值在 IVC 前后无差异。利多卡因组的平均 VAS 评分明显低于对照组（ < 0.001）。两组的当前 VDS 存在显著差异。利多卡因组报告轻度疼痛的患者比例明显高于对照组（ < 0.001）。
根据本研究结果，在 IV 套管前使用利多卡因浸渍的软垫敷料可显著减轻 IVC 过程中的疼痛感觉。
