Abstract

Abstract Background Regardless the progress in perioperative care postoperative cognitive decline (PCD) has been accepted unequivocally as a significant and frequent complication of surgery in older patients. The aim of this study was to evaluate the incidence of postoperative cognitive decline and its influence on quality of life three months after surgery. Methods Observational, prospective study in a Post-Anesthesia Care Unit (PACU) in patients aged above 45 years, after elective major surgery. Cognitive function was assessed with Montreal Cognitive Assessment (MOCA); Quality of life (QoL) was assessed using SF-36 Health Survey (SF-36). Assessments were performed preoperatively (T0) and 3 months after surgery (T3). Results Forty-one patients were studied. The incidence of PCD 3 months after surgery was 24%. At T3 MOCA scores were lower in patients with PCD (median 20 vs. 25, p = 0.009). When comparing the median scores for each of SF-36 domains, there were no differences between patients with and without PCD. In patients with PCD, and comparing each of SF-36 domains obtained before and three months after surgery, had similar scores for every of the 8 SF-36 areas while patients without PCD had better scores for six domains. At T3 patients with PCD presented with higher levels of dependency in personal activities of daily living (ADL). Conclusion Three months after surgery patients without PCD had significant improvement in MOCA scores. Patients with PCD obtained no increase in SF-36 scores but patients without PCD improved in almost all SF-36 domains. Patients with PCD presented higher rates of dependency in personal ADL after surgery.

Resumo

Resumo Justificativa e objetivo Independente do progresso do tratamento no período perioperatório, o declínio cognitivo no pós-operatório (DCPO) é inequivocamente aceito como uma complicação importante e frequente da cirurgia em pacientes mais velhos. O objetivo deste estudo foi avaliar a incidência de DCPO e sua influência na qualidade de vida três meses após a cirurgia. Métodos Estudo prospectivo observacional conduzido em Sala de Recuperação Pós-anestesia (SRPA) com pacientes de idade superior a 45 anos, após cirurgia eletiva de grande porte. A função cognitiva foi avaliada com o teste de Avaliação Cognitiva de Montreal (MOCA) e a qualidade de vida (QV) com o Questionário sobre Qualidade de Vida (SF-36). As avaliações foram realizadas no pré-operatório (T0) e três meses após a cirurgia (T3). Resultados Foram avaliados 41 pacientes. A incidência de DCPO três meses após a cirurgia foi de 24%. Em T3, os escores MOCA foram menores nos pacientes com DCPO (mediana 20 vs. 25, p = 0,009). Ao comparar as medianas dos escores para cada um dos domínios do SF-36, não observamos diferenças entre os pacientes com e sem DCPO. Ao comparar cada um dos domínios do SF-36 obtidos antes e após três meses de cirurgia, os pacientes com DCPO apresentaram resultados semelhantes para cada uma das oito áreas do SF-36, enquanto pacientes sem DCPO apresentaram resultados melhores em seis domínios. Em T3, os pacientes com DCPO apresentaram níveis mais elevados de dependência na realização de atividades cotidianas. Conclusão Três meses após a cirurgia, os pacientes sem DCPO apresentaram melhora significativa dos escores MOCA. Os pacientes com DCPO não apresentaram aumento dos escores SF-36, mas os pacientes sem DCPO apresentaram melhora em quase todos os domínios do SF-36. Os pacientes com DCPO apresentaram taxas mais elevadas de dependência na realização de atividades cotidianas após a cirurgia.
