Abstract
OBJETIVO: determinar a eficácia do spray de lidocaína a 10% aplicado no colo uterino antes da execução da histeroscopia diagnóstica para reduzir a dor e o desconforto causados pelo exame. MÉTODOS: Participaram do estudo 261 pacientes atendidas consecutivamente, entre março de 2004 e março de 2005. As pacientes foram randomizadas para dois grupos: um grupo recebendo aplicação tópica do spray de lidocaína (grupo lidocaína) e outro não recebendo nenhuma medicação antes do procedimento (grupo controle). Trinta miligramas de lidocaína spray a 10% foram aplicados na superfície do colo uterino, sendo a histeroscopia iniciada cinco minutos depois. Imediatamente após o final do procedimento a paciente respondeu um questionário sobre dor e quantificou a intensidade da dor, em centímetros, usando uma escala analógica visual não graduada. Os testes t não pareado, Mann-Whitney e chi2 foram aplicados na análise estatística, com nível de significância de 0,05. RESULTADOS: não houve diferença entre os grupos quanto à idade, paridade ou porcentagem de pacientes na menacme ou menopausa, ou quanto à indicação do procedimento e os achados histeroscópicos. Uma biópsia foi realizada em 57 das 132 pacientes no grupo lidocaína, e em 48 das 129 do grupo controle (p=0,96). O escore médio de dor foi 4,3±2,9 no grupo lidocaína, e 3,9±2,5 no grupo controle (p=0,2). Diferença no escore médio de dor foi observada somente na comparação entre pacientes na menacme e menopausa recebendo ou não a lidocaína spray, com p=0,01 e 0,04, respectivamente. CONCLUSÕES: o uso da lidocaína spray durante a histeroscopia diagnóstica não minimiza o desconforto e a dor das pacientes, e não deve ser utilizada.
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 chi2 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.
