T. Raveh et al., EFFICACY OF THE TOPICAL ANESTHETIC CREAM, EMLA, IN ALLEVIATING BOTH NEEDLE INSERTION AND INJECTION PAIN, Annals of plastic surgery, 35(6), 1995, pp. 576-579
To assess the efficacy of the topical anesthetic cream, EMLA, in allev
iating the pain produced by infiltration of local anesthetic prior to
surgical skin biopsies, a randomized, double-blind, placebo-controlled
study was performed on 54 patients undergoing 162 excisional biopsies
, Both pain induced by needle insertion and pain induced by local inje
ction were significantly diminished after topical application of EMLA
cream. However, part of the effect was placebo, because the placebo oi
ntment (Vaseline) also produced significant pain alleviation.
