Comparing Effects of Rhythmic Breathing and Lidocaine Spray on Pain Intensity During Needle Insertion Into Arteriovenous Fistula in Hemodialysis Patients: A Randomized Controlled Trial.
Anesthesiology and Pain Medicine 2023 April
BACKGROUND: Hemodialysis patients suffer from pain caused by needle insertion into the fistula site. Non-pharmacological methods may be associated with acceptable effects.
OBJECTIVES: The present study aimed to compare the effects of two interventions on pain intensity during needle insertion into the arteriovenous fistula in hemodialysis patients.
METHODS: This self-controlled, single-blind clinical trial was conducted on 54 hemodialysis subjects with arteriovenous fistula in Mashhad in 2021. In this regard, the patients were selected according to the inclusion criteria and randomly assigned to two groups (lidocaine spray and rhythmic breathing). In each group, pain intensity was assessed based on the visual analogue scale (VAS) before the intervention, followed by measuring the post-intervention pain intensity during three consecutive hemodialysis sessions every other day. Regarding the lidocaine spray group, two puffs of 10% lidocaine spray (20 mg) were sprayed on the needle insertion site five minutes before cannulation. However, the patients in another group took a long deep breath through the nose with three numbers, held their breath in the lungs for three numbers, and slowly exhaled through the mouth with three numbers two minutes before cannulation. The data were analyzed using SPSS software version 20, and Mann-Whitney U, Wilcoxon, chi-squared, and paired t -tests were run. In this study, P < 0.05 was considered significant.
RESULTS: The results represented a significant decrease in the pain severity scores of both rhythmic breathing (P = 0.023) and lidocaine spray (P < 0.001) groups after the intervention. Moreover, a more significant difference was observed between pre-and post-intervention pain intensity scores in the group treated with lidocaine spray (1.16 ± 1.56) compared to the other group (0.508 ± 1.25).
CONCLUSIONS: 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.
