Abstract
AIM
The aim of this study was to assess the effects of alkane vapocoolant spray in reducing pain during arteriovenous access cannulation in adult patients undergoing hemodialysis.
BACKGROUND
Developing and applying various approaches for pain relief remain important responsibility for nurses.
METHODS
This study was designed as an experimental study with a cross-over design. Thirty-eight patients on hemodialysis volunteered to undergo cannulation of their arteriovenous access, after the application of vapocoolant or placebo spray or no intervention. Subjective and objective pain levels were assessed, along with various physiological parameters pre- and post-cannulation.
RESULTS
Statistically significant between-group differences were observed in subjective pain at the venous (F = 4.97, p = 0.009) and arterial (F = 6.91, p = 0.001) puncture sites. The mean arterial site subjective pain scores were 4.45 ± 1.31 (no treatment), 4.04 ± 1.82 (placebo), and 2.98 ± 1.53 (vapocoolant spray). Significant between-group differences were observed in objective pain scores during arteriovenous fistula puncture (F = 5.13, p = 0.007). The mean objective pain scores after arteriovenous fistula puncture were 3.25 ± 2.66 (no treatment), 2.17 ± 1.76 (placebo), and 1.78 ± 1.66 (vapocoolant spray). Post-hoc test results indicated vapocoolant spray application was associated with significantly lower pain scores than no treatment or placebo. Patient blood pressure and heart rate recordings did not differ among the interventions.
CONCLUSION
Vapocoolant application was significantly more effective than the placebo or no treatment in reducing the pain of cannulation in adult patients undergoing hemodialysis.
