Title in Portuguese
Impacto da terapia farmacológica de suporte nas variáveis hemodinâmica, de função renal e mortalidade de pacientes em sepse grave e choque séptico

Abstract in Portuguese
A sepse grave e o choque séptico são complicações decorrentes de um processo infeccioso, associados à alta mortalidade em UTI e caracterizados por disfunção cardiovascular, renal e metabólica. A terapia farmacológica (TF) visa oferecer suporte hemodinâmico e reduzir níveis glicêmicos. Nesse cenário, o presente estudo objetivou analisar o impacto da TF e da alteração glicêmica na evolução clinica do paciente em sepse grave e choque séptico nas primeiras 72 horas.Trata-se de um ensaio clínico controlado randomizado em que os pacientes (n=46) foram alocados em grupos glicêmicos intensivo (manutenção da glicemia entre 80-110mg/dl) e convencional (manutenção da glicemia entre180-220mg/dl). Os dados foram coletados no período de 2004-2006 em um Hospital Universitário do Município de São Paulo. Na análise estatística foram usados os testes t-student, Qui-Quadrado, sendo considerados significativo p<0,05. Os resultados mostraram que a amostra foi constituída por pacientes do sexo masculino (58,7%), clínicos (78,3%) que apresentaram choque séptico (78,3%) decorrente de infecções no sistema respiratório (39,1%), com disfunção cardíaca (36,9%) e que apresentaram lesão renal aguda (56,5%). A média de idade foi de 51,6 anos. Os medicamentos de suporte mais prescritos foram noradrenalina (69,6%; 56,5%), hidrocortisona (56,5%;67,4%) e insulina (67,4%;73,9%), nas 24 e 48 h. Na comparação entre os grupos, observou-se diferença estatisticamente significante (p=0,00) na média glicêmica; não houve diferença estatisticamente significantes para as variáveis FC mínima (p= 0,68), máxima (p=0,11), PAM mínima (p=0,06) e máxima (p=0,11), no DU (p=0,23), Cr (p=0,33), volume infundido de cristalóides (p=0,10) e na mortalidade (p=0,11). A instabilidade hemodinâmica no grupo convencional foi mais duradoura e os óbitos ocorreram, apenas, entre os pacientes alocados no grupo convencional. Dessa forma, os dados sugerem que o controle glicêmico intensivo favorece o restabelecimento hemodinâmico de pacientes em choque séptico e, de certo modo, os protege do desfecho mortalidade

Abstract in English
Severe sepsis and septic shock are complications that develop from an inflammatory process leading to high mortality in the intensive care unit (ICU) and characterized by cardiovascular, renal and metabolic dysfunction. The pharmacological therapy (PT) aims at offering hemodynamic support and at reducing glycemic levels. In this scenario, the present study had the objective of analyzing the impact of PT and of the glycemic alteration in the clinical evolution of severe sepsis and septic shock patients in the first 72 hours. This is a randomized control trial in which the patients (n=46) were divided into intensive glycemic group (maintenance of glycemia between 80-110mg/dl) and conventional glycemic group (maintenance of glycemia between 180-220 mg/dl). The data were collected in the 2004-2006 period in a University Hospital in the city of São Paulo. In the statistical analysis, the tests used were t-student, Qui-Quadrado, being considered meaningful p<0,05. The results showed that the sample was formed by male patients (58.7%), clinical patients (78.3%) that presented septic shock (78.3%) as a result of infection in the respiratory system (39.1%), with cardiac dysfunction (36.9%) and those that presented acute renal lesion (56.5%). The average age was 51.6 years. The most commonly prescribed support drugs were noradrenaline (69.6%, 56.5%) and hydrocortisone (56.5%, 67.4%) in the first 24 and 48 hours. In the comparison between groups, statistically significant difference was observed (p=0,00) in the glycemic average, there was no statistically significant difference for the variables: minimal FC (p=0,68), maximum (p=0,11), minimum PAM (p=0,06) and maximum (p=0,11), DU (p=0,23), CR (p=0,33), volume infundido de cristalóides (p=0,10) and mortality (p=0,11). The hemodynamic instability in the conventional group lasted longer and deaths occurred only among the conventional group patients. Therefore, the data suggest that the intensive glycemic control favors the hemodynamic recovery of septic shock patients and, in a way, protects them from death
