BackgroundPatients undergoing hemodialysis experience constant fear and anxiety due to the pain of the insertion of dialysis needles, which might lead to certain physiological and psychological complications for them in the long term. It is therefore essential to control their pain through a simple, safe method.ObjectiveThe present study was conducted to determine the effect of the topical application of lavender essential oil on the intensity of pain during the insertion of dialysis needles in hemodialysis patients.DesignThis open crossover study was conducted on 34 hemodialysis patients with arteriovenous fistula (AVF) admitted to the dialysis unit of one of the hospitals of Semnan University of Medical Sciences in 2013. The intensity of pain was measured in all the patients in three different states during the insertion of arterial needles for hemodialysis: (1) The topical application of 100% lavender essential oil, (2) no intervention, (3) placebo (with water).Main Outcome MeasuresPain intensity was measured in this study through the numeric rating scale (NRS) of pain.ResultsThe findings showed that the mean±SD of pain intensity was 2.91±1.69 with the topical application of lavender, 4.59±2.02 in the no intervention state and 4.18±1.66 with the placebo state. Statistical tests showed a significant difference between the patients' intensity of pain in the three different states (p=0.001).ConclusionBased on the findings of the study, the topical application of lavender decreases moderate intensities of pain during the insertion of dialysis needles. Accordingly, lavender oil may be an option to reduce pain by insertion of hemodialysis needles.Copyright © 2015 Elsevier Ltd. All rights reserved.
