randomized double-blind clinical trial of eutectic mixture of local anesthetic creams in reducing pain during hysterosalpingography

conclusions this study does not support the use of emla for hsg. results there was no significant difference in the efficacy between emla and placebo creams in pain perception during the entire procedure. there was no significant difference in long term pain perception half an hour after the hsg performance. patients and methods eighty patients undergoing hsg as part of infertility evaluation were randomly allocated to groups receiving either emla (n = 40) or placebo cream (n = 40) in a double-blinded prospective study. fifteen minutes before hsg, 5 grams of 5% cream was applied to the uterine cervix using a cervical applicator. the degree of pain experienced by the patient was evaluated during and after hsg at five predefined steps on a visual analogue scale (vas). objectives to assess the efficacy of applying eutectic mixture of local anesthetics (lidocaine-prilocaine cream) (emla) on the uterine cervix in reducing pain during hsg. background hysterosalpingography (hsg) is considered as a primary test in infertility work up worldwide due to its reliability in evaluating abnormalities related to the uterus and fallopian tubes.
