Résumé : |
"Objective To compare pain perception using 3 anesthetics (eutectic mixture of local anesthetics [EMLA], vapocoolant spray, and ice) compared with a control (no anesthetic) during botulinum toxin type A (BTX-A) injections for lower limb spasticity. Design A placebo-controlled, single-blinded study where each study patient served as their own control. Setting Spasticity clinic. Participants Subjects (N=30) with ankle spasticity who visited the clinic for BTX-A injections in the gastrocnemius muscle were consecutively sampled. Intervention The gastrocnemius muscle was divided into 4 quadrants and 1 of the 3 different anesthetic agents was applied to each quadrant with 1 quadrant using no anesthetic, control. Main Outcome Measures Numerical Rating Scale (NRS) and the Wong-Baker FACES scale. Results Pain perception using the NRS and FACES scale was significantly lower using ice and EMLA compared with control and spray conditions (P<.05 pain perception using emla and ice was similar. these results indicate that patients experience minimal to moderate during btx-a injections.> Conclusions Pain relief offered by EMLA and ice was comparable, suggesting that ice is a more convenient option because of brief application time (compared with EMLA). Spray may have made the patients more sensitive to pain and alternative approaches for using vapocoolant should be considered." |
