ROSA E SILVA, Júlio César et al. Use of lidocaine spray in diagnostic hysteroscopy. Rev. Bras. Ginecol. Obstet. [online]. 2007, vol.29, n.4, pp.181-185. ISSN 0100-7203.

PURPOSE: to determine the efficacy of 10% lidocaine spray applied to the cervix before the procedure of diagnostic hysteroscopy, in order to reduce the painful process and the discomfort caused by the exam. METHODS: a total of 261 consecutive patients participated in the study, which was conducted from March 2004 to March 2005. The patients were randomly assigned to one of two groups: one group receiving topical lidocaine spray (lidocaine group - LdG) and the other, receiving no medication before the procedure (control group - CG). In the LdG patients, thirty milligrams of 10% lidocaine spray were applied to the surface of the cervix five minutes before hysteroscopy started. Immediately, after the end of the procedure, the patients from both groups were asked to respond to a questionnaire about pain and to quantify the pain, in centimeters, using a 10-cm non-graduated visual analog scale. The unpaired t test, the Mann-Whitney test and the c2 test were used for statistical analyses, considering p significant if lower than 0.05. RESULTS: there was no statistically significant difference between groups regarding age, parity or percentage of patients in menacme or menopause, or regarding the indications for the procedure and the hysteroscopic findings. A biopsy was necessary in 57 of the 132 LdG patients and in 48 of the 129 CG patients (p=0.96). The mean pain score was 4.3±2.9 in LdG and 3.9±2.5 in CG (p=0.2). A difference in the mean pain score was observed only among patients in menacme and menopause receiving or not the lidocaine spray, with p=0.01 and p=0.04 respectively. CONCLUSIONS: the use of lidocaine spray during diagnostic hysteroscopy does not minimize the discomfort and pain of the patients and therefore should not be applied.
