A influência do Delirium no tempo de ventilação mecânica em pacientes críticos: uma revisão sistemática
Conteúdo do artigo principal
Resumo
O delirium consiste em um estado confusional agudo e de curso flutuante representando uma manifestação da disfunção cerebral que pode estar associado com diferentes manifestações clínicas. Os pacientes com delirium têm sido estudados, pois tem apresentado maior tempo de ventilação mecânica e de internação em unidade de terapia intensiva. O objetivo do estudo foi realizar uma revisão de literatura acerca da influência do delirium no tempo de ventilação mecânica, sedação e na mortalidade de pacientes internados em unidade de terapia intensiva. Nos métodos foi realizada uma busca por estudos nas bases de dados: PubMed e Embase, com os descritores delirium, intensive care unit and mechanical ventilation. Nos resultados foram incluídos oito artigos, um recebeu graduação A e sete receberam graduação B na escala de Oxford. Os principais resultados foram: Os pacientes com delirium apresentaram maior gravidade, maior tempo de ventilação mecânica, maior tempo de sedação e maior mortalidade. Conclui-se que o delirium parece estar associado ao maior tempo da ventilação mecânica, maior dosagem de sedação e de mortalidade nestes pacientes.
