Thermotherapy for Reducing Pain During Arteriovenous Fistula Cannulation

Istanbul University51 enrolled

Overview

Arteriovenous fistula (AVF) cannulation is a routine procedure for people receiving haemodialysis and is frequently associated with pain. Thermotherapy has been reported as an effective non-pharmacological intervention for reducing AVF cannulation-related pain; however, the optimal application duration remains unclear.

Thermotherapy is the therapeutic application of any substance to the body that adds heat to the body resulting in increased tissue temperature. Thermotherapy increases tissue tem-perature, blood flow, metabolism, and connective tissue extensibility. Some of the benefits provided by topical heat therapy may be mediated di¬rectly in the brain. Functional brain imag¬ing research has revealed central ef¬fects of non-noxious skin warming with increased activation of the thalamus and posterior insula of the brain. In addition, innocuous tactile stimulation of the skin activates the thalamus and S2 region of the cerebral cortex. These direct effects on the brain may mitigate the sensation of pain in the brain, thereby providing pain relief. Two studies were found in the literature evaluating the effect of thermotherapy on fistula-related cannulation pain. In both studies, thermotherapy treatment was found to be effective in reducing pain. Although it is stated in the literature that thermotherapy can be applied for 5-30 minutes , research shows that it is applied for 15 minutes, 10 minutes and 20 minutes. Thermotherapy was administered in three sessions, and in one session. This randomized controlled trial was conducted to evaluate the effectiveness of different application durations (5 and 10 minutes) of thermotherapy on reducing pain during AVF cannulation for long period (12 dialysis sessions). Investigators hypothesized that the 5 minutes thermotherapy is the optimal time to alleviate the patients' fistula cannulation related pain.

Outcomes

Primary Outcomes

Change From Baseline Fistula Cannulation Related Pain

It will be assessed six times at the end of the dialysis session with Visual Analogue Scale. Visual Analogue Scale ranging from 0 (no pain) to 10 (worst pain). Pain increases the score increases. The high point describes bad outcome

Time frame: Up to 2 weeks (3 hemodialysis sessions in a week)
