BACKGROUND
The venous cannulation procedure was widely used in many clinical procedures; however, it is associated with pain or discomfort.
OBJECTIVES
The purpose of this study was to investigate whether transcutaneous electrical nerve stimulation (TENS) could reduce pain during cannulation of vein.
METHODS
One hundred patients were allocated randomly to 2 groups. In the active TENS group, TENS was delivered via 2 electrodes on the venous cannulation site (radial side of the wrist of dominant forearm) 20 minutes before venous cannulation, and the control group received placebo (no current) TENS. Venous cannulation with a 22-gauge cannula was performed. During venous cannulation, the pain intensity (0 = no pain, 10 = worst pain imaginable) was measured. Any side effects during study periods were recorded.
RESULTS
The incidence of pain during venous cannulation was similar between the 2 groups. However, pain intensity was significantly lower in the active TENS group than placebo group (P < 0.01). There was no significant difference in the side effects such as erythema and itching between the groups.
CONCLUSIONS
TENS may be a suitable option for reducing the pain intensity during venous cannulation. ClinicalTrials.gov identifier: NCT01607463.
背景
静脉插管操作在许多临床操作中广泛应用；然而，它会引起疼痛或不适。
目的
本研究旨在调查经皮电刺激神经疗法（TENS）是否能减轻静脉插管过程中的疼痛。
方法
100例患者随机分为两组。在主动TENS组中，在静脉插管前20分钟通过2个电极在静脉插管部位（优势前臂手腕桡侧）给予TENS，对照组接受安慰剂（无电流）TENS。使用22号套管进行静脉插管。在静脉插管过程中，测量疼痛强度（0 = 无疼痛，10 = 可想象的最严重疼痛）。记录研究期间的任何副作用。
结果
两组静脉插管期间疼痛发生率相似。然而，主动TENS组的疼痛强度明显低于安慰剂组（P < 0.01）。两组之间在红斑和瘙痒等副作用方面无显著差异。
结论
TENS可能是减轻静脉插管期间疼痛强度的合适选择。ClinicalTrials.gov标识符：NCT01607463。
