Comparação do efeito analgésico entre etoricoxib 90 mg e dipirona sódica na exérese de pterígio primário com transplante autólogo de conjuntiva. Arquivos Brasileiros de Oftalmologia, São Paulo, v. 72, n. 5, p. 661-664, 2009.0004-2749e- 1678-2925http://repositorio.bc.ufg.br/handle/ri/17615Purpose: To compare the analgesic effect between dipyrone, 90 mg etoricoxib, and placebo after excision of primary ptery- gium with conjunctival autograft. Methods: Prospective, ran- domized, double-masked clinical trial. Three groups of 26 pa- tients (one eye per patient) were submitted to surgery and re- ceived the study drugs for five days after surgery. A scale of pain was used, graduated from zero to ten, for patient evalua- tion in the first, third and fifth postoperative days. The pain was classified as absent (zero), mild (1 to 3), moderate (4 to 7) and severe (8 to 10). Statistical analysis was performed with the SPSS, version 11.5. Results: A statistically significant dif- ference was found between etoricoxib and dipyrone in the first and third postoperative days (p=0.001 and p=0.01; respecti- vely). Etoricoxib was superior to placebo only in the first pos- toperative day (p=0.04). There was no significance in the com- parison between dipyrone and placebo. Conclusions: Anal- gesia of etoricoxib was superior to placebo in the first pos- toperative day and to dipyrone in the third and fifth days after excision of primary pterygium with conjunctival autograft. There was no significant difference between dipyrone and placebo in all time points.porAcesso AbertoDor pós-operatóriaConjuntiva/transplantePterígioAnalgesiaPlaceboDipirona/uso terapêuticoPiridinas/uso terapêuticoPain, postoperativePterygiumConjunctiva/transplantationPlaceboAnalgesiaPyridi- nes/therapeutic useDipyrone/therapeutic useArtigo10.1590/S0004-27492009000500012
