Abstract
Objetivos: determinar os principais fatores associados à ocorrência de infecção do sítio cirúrgico em pacientes submetidas a histerectomia total abdominal (HTA) no Instituto Materno ¾ Infantil de Pernambuco (IMIP). Métodos: realizou-se um estudo de corte transversal incluindo todas as pacientes submetidas a histerectomia total abdominal no IMIP no período de janeiro de 1995 a dezembro de 1998, desde que tivessem retornado no 7º e no 30º dia pós-operatório para controle de infecção (n = 414). A freqüência de infecção do sítio cirúrgico (definida pelos critérios do CDC, 1998) foi de 10% (42 casos). Calculou-se o risco de prevalência (RP) de infecção do sítio cirúrgico e seu intervalo de confiança (IC) a 95% para as seguintes variáveis: idade, obesidade, hipertensão, diabetes, doença maligna, tipo de incisão, tempo cirúrgico e antibioticoprofilaxia. Realizou-se análise de regressão logística múltipla para determinação do risco ajustado de infecção. Resultados: encontrou-se aumento significativo do risco de infecção do sítio cirúrgico para as seguintes variáveis: idade >60 anos (RP = 2,39; IC-95% = 1,15-4,94), obesidade (RP = 3,2; IC-95% = 1,83-5,59), duração da cirurgia >2 horas (RP = 2,36; IC-95% = 1,32-4,21) e associação com diabetes (RP = 6,0; IC-95% = 3,41-10,57). Por outro lado, o risco de infecção esteve significativamente diminuído quando utilizou-se antibiótico profilático (RP = 0,38; IC-95% = 0,21-0,68). Não se encontrou associação estatisticamente significativa de infecção com o tipo de incisão, a indicação da cirurgia por patologia maligna e a presença de hipertensão. Conclusões: os fatores associados a risco aumentado de infecção do sítio cirúrgico pós-HTA no IMIP foram: idade >60 anos, obesidade, diabetes e duração da cirurgia >2 horas. A antibioticoprofilaxia apresentou efeito protetor, com diminuição do risco de infecção.
Purpose: to determine the main factors associated with the occurrence of surgical site infection in patients submitted to total abdominal hysterectomy at the Instituto Materno ¾ Infantil de Pernambuco (iMIP). Methods: a cross-sectional study was conducted, enrolling patients submitted to total abdominal hysterectomy at IMIP who returned to postsurgical consultation for infection control, between January, 1995 and December, 1998 (n = 414). The frequency of surgical site infection (defined according to the CDC criteria, 1998) was 10% (42 cases). Prevalence risk (PR) of infection (dependent variable) and its 95% confidence interval (CI) were calculated for independent variables: age, obesity, hypertension, diabetes, malignant pathology, type of incision, duration of surgery and antibiotic prophylaxis. Multiple logistic regression analysis was used to determine adjusted risk of infection. Results: a significantly increased risk of infection was found for the following variables: age >60 years (PR = 2.39, 95% CI = 1.15-4.94), obesity (PR = 3.2, 95% CI = 1.83-5.59), duration of surgery >2 hours (PR = 2.35, 95% CI = 1.32-4.21) and diabetes (PR = 6.0, 95% CI = 3.41-10.57). On the other hand, risk of infection was significantly reduced when antibiotic prophylaxis was administered (PR = 0.38, 95% CI = 0.21-0.68). Type of incision, malignant disease and hypertension were not associated with infection. Conclusions: the factors associated with increased risk of surgical site infection after total abdominal hysterectomy at IMIP were: age >60 years, obesity, diabetes and surgical duration >2 hours. Antibiotic prophylaxis showed a protective effect with reduction of risk of infection.
