Effect of lidocaine gel on pain from copper IUD insertion: a randomized double-blind controlled trial.

What Was Tested

Researchers studied Copper (Supplement) in this randomized controlled trial publication.

To determine the effect of lidocaine gel on pain from TCu-380AIUD insertion.

Why It Was Studied

Further study has been recommended on the effects of lidocaine (xylocaine) gel on IUD insertion pain in the recent Cochran review.

Kruskal-Wallis and linear regression in SPSS-13 were used to identify effect of lidocaine gel on the pain.

Who Took Part

The study group was 96 women.

The age groups tagged for this paper are young adults and adults, women only.

At a health center in Tabriz, Iran, 96 women were allocated into 3 groups using block randomization with 6 and 9 block sizes considering allocation concealment.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

The women were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.

As a double-blind Copper (Supplement) study, the assignments were hidden from both participants and investigators until the end.

Immediately after IUD insertion, pain during the insertion was measured using 0-10 cm visual analogue scale.

What Was Measured

The subject headings attached to it are Anesthetics, Local, Gels, Intrauterine Devices, Copper, Lidocaine, Pain and Prosthesis Implantation.
