ABSTRACT
JUSTIFICATIVA E OBJETIVOS: Sepse é a principal causa de morte em pacientes tratados em unidade de terapia intensiva (UTI). O objetivo deste estudo foi avaliar etiologia, fatores prognósticos e mortalidade de pacientes sépticos tratados nas UTI de Passo Fundo, Brasil. MÉTODO: Foram avaliados 971 pacientes consecutivos prospectivamente, entre agosto de 2005 e fevereiro de 2006, 560 foram selecionados pela presença de síndrome da resposta inflamatória sistêmica (SIRS) e acompanhados por 28 dias ou até a alta ou óbito. Os pacientes foram classificados de acordo com a etiologia da SIRS e adicionalmente classificados como tendo SIRS, sepse, sepse grave e choque séptico. O prognóstico foi avaliado por meio dos escores APACHE II e SOFA. A mortalidade foi comparada em diferentes etiologias de sepse e parâmetros APACHE II e SOFA. RESULTADOS: Dos 971 pacientes admitidos nas UTI, 560 desenvolveram SIRS (58 por cento). A causa mais freqüente de internação foi doença neurológica (28,9 por cento), o mais freqüente local de infecção foi o trato respiratório (71,6 por cento), e os germes mais prevalentes foram os bacilos gram-negativos (53,2 por cento). O escore APACHE II médio foi 18 ± 9 e o escore SOFA médio foi 5 ± 4. O tempo médio de permanência foi 6 (3-11) dias e a taxa de mortalidade foi 31,1 por cento: 6,1 por cento para SIRS não infecciosa, 10,1 por cento para sepse, 22,6 por cento para sepse grave e 64,8 por cento para choque séptico. CONCLUSÕES: Sepse é um importante problema de saúde que leva a uma taxa extremamente alta de mortalidade nas UTI de Passo Fundo, Brasil.
BACKGROUND AND OBJECTIVES: Sepsis is the main cause of death in patients treated in intensive care units (ICU). The aim of this study was to evaluate etiology, prognostic factors and mortality of septic patients treated in ICU of Passo Fundo, Brazil. METHODS: Out of 971 consecutive patients prospectively evaluated from August 2005 to February 2006, 560 were selected due to presence of systemic inflammatory response syndrome (SIRS) and followed for 28 days or until discharge or death. Patients were categorized according with the etiology of SIRS and further classified as having SIRS, sepsis, severe sepsis and septic shock. Prognosis was assessed by means of Apache II and SOFA. Mortality was compared in different etiologies of sepsis, APACHE II and SOFA scores, parameters. RESULTS: Of the 971 patients admitted to the ICU, 560 developed SIRS (58 percent). The most frequent cause of internation was neurological disease (28.9 percent), the most frequent site of infection was the respiratory tract (71.6 percent), and the most prevalent pathogens were gram-negative bacilli (53.2 percent). Mean APACHE II score was 18 ± 9, and mean SOFA score was 5 ± 4. Median ICU stay was 6 (3-11) days and overall mortality rate was 31.1 percent: 6.1 percent for non-infectious SIRS, 10.1 percent for sepsis, 22.6 percent for severe sepsis, and 64.8 percent for septic shock. CONCLUSIONS: Sepsis is an important health problem that leads to an extremely high mortality rate in the ICU of Passo Fundo, Brazil.
