Abstract

Arteriovenous fistula puncture pain is a serious problem for patients undergoing dialysis and a good indication for topical anesthetics. No previous study has compared lidocaine/prilocaine cream (EMLA) with lidocaine tape for pain relief during arteriovenous fistula puncture in patients undergoing maintenance hemodialysis. To this end, we conducted a multicenter randomized crossover study including 66 patients (mean age, 65.8 years; males, 57.6%) undergoing maintenance hemodialysis thrice/week. Subjects were assigned to Sequence EL (EMLA administration followed by lidocaine, with 1-week wash-out) or Sequence LE (reverse administration, first lidocaine then EMLA). All subjects completed the study. At each puncture site, 1 g EMLA (25 mg lidocaine + 25 mg prilocaine) or one sheet of lidocaine tape (18 mg lidocaine) was applied 1 h or 30 min prior to arteriovenous fistula puncture, respectively. The primary endpoint was puncture pain relief, which was measured using a 100-mm visual analog scale. The secondary endpoints included quality of life, which was measured by SF-36, and safety. EMLA produced a 10.1-mm greater visual analog scale improvement than lidocaine tape (P = 0.00001). However, there was no statistically significant difference in the quality of life between the two groups, and no significant carryover/period effect was observed in any analysis. Further, no drug-related adverse events were observed. Taken together, these results suggest that EMLA cream is superior to lidocaine tape for the relief of arteriovenous fistula puncture pain in patients undergoing maintenance hemodialysis.
