The Effect of Transcutaneous Electrical Nerve Stimulation on Pain During Venous Cannulation

Not Applicable

Completed

• Conditions: Cannulation Pain
• Interventions: Procedure: Transcutaneous electrical nerve stimulation (Empi, USA)

• Registration Number: NCT01607463
• Lead Sponsor: Kyungpook National University Hospital

Brief Summary

The purpose of this study was to investigate whether transcutaneous electrical nerve stimulation (TENS) could reduce pain during cannulation of vein.

Detailed Description

One hundred patients were allocated randomly to two groups: In the active TENS group TENS was delivered via two electrodes on the venous cannulation site (radial side of the wrist of dominant forearm) 20 min prior to venous cannulation and control group received placebo (no current) TENS. Venous cannulation with a 22 gage 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

Arm && Interventions

Group	Intervention	Description
active TENS group	Transcutaneous electrical nerve stimulation (Empi, USA)	Two electrodes were attached to the radial side of dominant forearm. In the active TENS group, TENS was delivered via two electrodes on the venous cannulation site
Placebo group	Transcutaneous electrical nerve stimulation (Empi, USA)	Two electrodes were attached to the radial side of dominant forearm. In the placebo group the TENS device had no current output although the power "on" indicator light remained active.
