RESUMO

Abstract Background and objective: Sugammadex is the first selective relaxant binding agent. When compared with neostigmine, following sugammadex administration patients wake earlier and have shorter recovery times. In this study, we hypothesized that fast and clear awakening in patients undergoing general anesthesia has positive effects on cognitive functions in the early period after operation. Methods: Approved by the local ethical committee, 128 patients were enrolled in this randomized, prospective, controlled, double-blind study. Patients were allocated to either Sugammadex group (Group S) or the Neostigmine group (Group N). The primary outcome of the study was early postoperative cognitive recovery as measured by the Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE). After baseline assessment 12-24 h before the operation. After the operation, when the Modified Aldrete Recovery Score was ≥9 the MMSE and 1 h later the MoCA tests were repeated. Results: Although there was a reduction in MoCA and MMSE scores in both Group S and Group N between preoperative and postoperative scores, there was no statistically significant difference in the slopes (p > 0.05). The time to reach TOF 0.9 was 2.19 min in Group S and 6.47 min in Group N (p < 0.0001). Recovery time was 8.26 min in Group S and 16.93 min in Group N (p < 0.0001). Conclusion: We showed that the surgical procedure and/or accompanying anesthetic procedure may cause a temporary or permanent regression in cognitive function in the early postoperative period. However, better cognitive performance could not be proved in the Sugammadex compared to the Neostigmine.


Resumo Justificativa e objetivo: Sugamadex é o primeiro agente de ligação relaxante seletivo. Após a administração de sugamadex, os tempos de despertar e de recuperação dos pacientes são menores, em comparação com neostigmina. Neste estudo, a hipótese foi que um despertar mais rápido e claro dos pacientes submetidos à anestesia geral tem efeitos positivos sobre as funções cognitivas no pós-operatório imediato. Métodos: Após a aprovação do Comitê de Ética local, 128 pacientes foram incluídos neste estudo prospectivo, randômico, controlado e duplo-cego. Os pacientes foram designados para o grupo sugamadex (Grupo S) ou grupo neostigmina (Grupo N). O desfecho primário do estudo foi a recuperação cognitiva no pós-operatório imediato, de acordo com a mensuração da Avaliação de Montreal da Função Cognitiva (MoCA) e com o Mini Exame do Estado Mental (MMSE), após a avaliação inicial 12-24 h antes da operação. Após a operação, quando o escore de recuperação de Aldrete modificado era ≥ 9, o teste MMSE e, uma hora depois, o teste MoCA foram repetidos. Resultados: Embora tenha havido uma redução nos escores de MoCA e MMSE tanto no Grupo S quanto no Grupo N, entre os escores pré- e pós-operatório não houve diferença estatisticamente significativa nas reduções (p > 0,05). O tempo para atingir TOF 0,9 foi de 2,19 min no Grupo S e de 6,47 min no Grupo N (p < 0,0001). O tempo de recuperação foi de 8,26 min no Grupo S e de 16,93 min no Grupo N (p < 0,0001) Conclusão: Mostramos que o procedimento cirúrgico e/ou procedimento anestésico de acompanhamento pode causar uma regressão temporária ou permanente da função cognitiva no pós-operatório imediato. No entanto, um desempenho cognitivo melhor não pode ser provado no grupo sugamadex em comparação com o grupo neostigmina.
