Comparing Effects of Rhythmic Breathing and Lidocaine Spray on Pain Intensity During Needle Insertion Into Arteriovenous Fistula in Hemodialysis Patients: A Randomized Controlled Trial.

The lidocaine spray group had a larger difference in the pre-and post-intervention pain intensity scores than the rhythmic group; however, the difference was not significant. The rhythmic breathing can be used by nurses as a non-pharmacological method with low complications in hemodialysis departments because of declining pain.
