Fatores associados à maior mortalidade e tempo de internação prolongado em uma unidade de terapia intensiva de adultos

OBJETIVO: A unidade de terapia intensiva e sinonimo de gravidade e apresenta taxa de mortalidade entre 5,4% e 33%. Com o aperfeicoamento de novas tecnologias, o paciente pode ser mantido por longo periodo nessa unidade, ocasionando altos custos financeiros, morais e psicologicos para todos os envolvidos. O objetivo do presente estudo foi avaliar os fatores associados a maior mortalidade e tempo de internacao prolongado em uma unidade de terapia intensiva adulto. METODOS: Participaram deste estudo todos os pacientes admitidos consecutivamente na unidade de terapia intensiva de adultos, clinica/cirurgica do Hospital das Clinicas da Universidade Estadual de Campinas, no periodo de seis meses. Foram coletados dados como: sexo, idade, diagnostico, antecedentes pessoais, APACHE II, dias de ventilacao mecânica invasiva, reintubacao orotraqueal, traqueostomia, dias de internacao na unidade de terapia intensiva, alta ou obito na unidade de terapia intensiva. RESULTADOS: Foram incluidos no estudo 401 pacientes, sendo 59,6% homens e 40,4% mulheres, com idade media de 53,8±18,0 anos. A media de internacao na unidade de terapia intensiva foi de 8,2±10,8 dias, com taxa de mortalidade de 13,46%. Dados significativos para mortalidade e tempo de internacao prolongado em unidade de terapia intensiva (p 11, traqueostomia e reintubacao. CONCLUSAO: APACHE >11, traqueostomia e reintubacao estiveram associados, neste estudo, a maior taxa de mortalidade e tempo de permanencia prolongado em unidade de terapia intensiva.
