description Background and objectives: Interleukin-6 is a predictor of trauma severity. The purpose of this study was to evaluate the effect of intravenous lidocaine on pain severity and plasma interleukin-6 after hysterectomy. Method: A prospective, randomized, comparative, double-blind study with 40 patients, aged 18–60 years. G1 received lidocaine (2 mg kg−1 h−1) or G2 received 0.9% saline solution during the operation. Anesthesia was induced with O2/isoflurane. Pain severity (T0: awake and 6, 12, 18 and 24 h), first analgesic request, and dose of morphine in 24 h were evaluated. Interleukin-6 was measured before starting surgery (T0), 5 h after the start (T5), and 24 h after the end of surgery (T24). Results: There was no difference in pain severity between groups. There was a decrease in pain severity between T0 and other measurement times in G1. Time to first supplementation was greater in G2 (76.0 ± 104.4 min) than in G1 (26.7 ± 23.3 min). There was no difference in supplemental dose of morphine between G1 (23.5 ± 12.6 mg) and G2 (18.7 ± 11.3 mg). There were increased concentrations of IL-6 in both groups from T0 to T5 and T24. There was no difference in IL-6 dosage between groups. Lidocaine concentration was 856.5 ± 364.1 ng mL−1 in T5 and 30.1 ± 14.2 ng mL−1 in T24. Conclusion: Intravenous lidocaine (2 mg kg−1 h−1) did not reduce pain severity and plasma levels of IL-6 in patients undergoing abdominal hysterectomy. Resumo: Justificativa e objetivos: A interleucina-6 (IL-6) é preditora de intensidade no trauma. O objetivo deste estudo foi avaliar o efeito da lidocaína por via venosa sobre a intensidade da dor e IL-6 após histerectomia. Método: O estudo foi prospectivo, randomizado, comparativo e duplo-encoberto em 40 pacientes, entre 18 e 60 anos. Foi administrada lidocaína (2 mg.kg−1.h−1) no G1 ou solução salina a 0,9% no G2 durante a operação. A anestesia foi com O2/isoflurano. Foi avaliada a intensidade da dor (T0: despertar e seis, 12, 18 e 24 horas), a primeira solicitação de analgésico, a dose de morfina nas 24 horas. A IL-6 foi medida antes do início da operação (T0), após cinco horas do início (T5) e 24 horas após o término (T24). Resultados: Não houve diferença na intensidade da dor entre os grupos. Ocorreu diminuição da intensidade da dor entre T0 e os outros momentos avaliados no G1. O tempo para primeira complementação foi maior no G2 (76,0 ± 104,4 min) do que no G1 (26,7 ± 23,3 min). Não houve diferença na dose de morfina complementar entre G1 (23,5 ± 12,6 mg) e G2 (18,7 ± 11,3 mg). Houve aumento das concentrações de IL-6 em ambos os grupos de T0 para T5 e T24. Não houve diferença na dosagem de IL-6 entre os grupos. A concentração de lidocaína foi 856,5 ± 364,1 ng.mL−1 em T5 e 30,1 ± 14,2 ng.mL−1 em T24. Conclusão: A lidocaína (2 mg.kg−1.h−1) por via venosa não promoveu redução da intensidade da dor e dos níveis plasmáticos de IL-6 em pacientes submetidas a histerectomia abdominal.
