Các yếu tố nguy cơ nhiễm khuẩn bệnh viện của các nhiễm khuẩn bệnh viện trên 671 bệnh nhân thường gặp tại khoa Hồi sức tích cực Nhi. Kết quả nghiên cứu cho thấy các yếu tố nguy cơ nhiễm khuẩn bệnh viện tại khoa hồi sức tích cực Nhi cho từng loại nhiễm khuẩn bệnh viện gồm có viêm phổi bệnh viện là có đặt nội khí quản
nhiễm khuẩn huyết bệnh viện là đặt thông tĩnh mạch trung tâm
nhiễm khuẩn vết mổ là phẫu thuật phẫu thuật đường tiêu hóa, loại phẫu thuật nhiễm bẩn, có đặt dẫn lưu trên 5 ngày
nhiễm khuẩn tiết niệu là có đặt thông tiểu trên 3 ngày.Objective: identify risk factors of common types of nosocomial infection for in pediatric intensive care unit. Study design: A prospective cohort study was carried out in Children's Hospital No.1 within 14 months. The enrolled patients in pediatric intensive care unit were longitudinally followed with main variables: demographic, nutrition status, underlying disease, PRISM, intervenbon, drug use and nosocomial infection. Risk factors were analysed with the logistic regression. Results: There were 671 patients enrolled in the study. The incidence of nosocomial infection was 23%, in which the nosocomial pneumonia (NP) was 49,4%, nosocomial bloodstream infection (NBI) was 24,4%, surgical site infection (SSI) was 11,1%, urinary tract infection (UTI) was 5,8%. The risk factors for each type of nosocomial infection were intubation (RR=22,3 (2,6 - 192,3)), length of intubation >
5 days (RR=8,9 (2,7 - 30,0)), H2 receptor antagonist (RR=3,0 (1,1 - 7,8)) for NP
central venous catheter (RR=4,1 (1,6 - 10,4), length of central venous catheter >
3 days (RR=6,4 (1,3 - 30,9), venotomy (RR=11,2 (4,7 - 26,9)), parenteral nutrition (RR=3,4 (1,6 - 7,4) for BSI
gasffointestinal surgery (RR= 6,6 (1,7 - 55,3), dirty and contaminated surgery ((W=3,2 (1,0 - 14,3)), drainage (RR=3,8 (1,0 - 14,3), length of drainage >
5 days (RR= 5,1 (1,1 - 26,6) for SSI
bladder catheter (RR=1,13 (1,1 - 1,2), length of bladder catheter >
3 days (RR=1,4 (1,1-1,8). Conclusion: The risk factors for each type of nosocomial infection included intubation, length of intubation >
5 days, H2 receptor antagonist for NP
central venous catheter, length of central venous catheter >
3 days, venotomy, parenteral nutrition for BSl
gastrointestinal surgery, dirty and confaminated surgery, drainage, length of drainage >
5 days for SSI
bladder catheter, length of bladder cattieter >
3 days. These results will support the more effective implementation of control measures for each type of nosocomial infection in pediatric intensive care unit.
