ABSTRACT

Objetivo: Avaliar o efeito preemptivo com nepafenaco 0,1% em pacientes submetidos à fotocoagulação da retina para tratamento da retinopatia diabética proliferativa. Métodos: Trinta pacientes foram submetidos à fotocoagulação com laser de argônio em ambos os olhos. O olho contralateral de cada paciente foi o controle. O nepafenaco e o placebo foram utilizados 30 minutos antes da aplicação do laser. Ambos os olhos foram fotocoagulados no mesmo dia. A intensidade da dor foi avaliada por meio da escala analógica visual e da escala descritiva de dor. Resultados: A análise da interação instilação versus nepafenaco mostrou que os pacientes do grupo placebo apresentaram níveis de dor semelhantes em ambos os olhos, e os do grupo nepafenaco apresentaram redução importante do nível de dor no olho em que foi instilado a suspensão de 0,1% quando comparado ao olho contralateral que recebeu placebo (p=0,023). Conclusão: Este estudo sugere que a suspensão de 0,1% de nepafenaco foi útil na analgesia preemptiva de pacientes submetidos à fotocoagulação de retina quando comparada ao placebo. .

The contralateral eye of each patient was the control. The nepafenac and placebo were used 30 minutes before the application of the laser. Both eyes were photocoagulated in the same day. Pain intensity was assessed by visual analog scale and descriptive pain scale Results: The analysis of the interaction instillation versus nepafenac showed that patients in the placebo group had similar levels of pain in both eyes, and the nepafenac group had significant reduction in pain in the eye that was instilled suspension of 0,1% when compared to the contralateral eye which received placebo (p = 0.023). Conclusion: This study suggests that a suspension of 0,1% nepafenac helpful for preemptive analgesia in patients undergoing retinal photocoagulation compared to placebo. .
