About

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

Full 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

Placebo group

Placebo Comparator group

Description:

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.
