Abstract:
OBJECTIVE To explore the factors and effective preventive method of nosocomial lower respiratory(infection) after general anesthesia through trachea intubation.METHODS Using bacterial culture and identification technique to detect the samples collected from pipe and the sides of anesthetic machine,from disposable virus/(bacteri)a respiratory filter and buccal and bronchial secretion of patients with general anesthesia through trachea(intubation.) RESULTS Eight of 15 anesthetic machines without disinfection were with positive bacterial culture.All sides of virus/bacteria respiratory filter,and buccal and bronchial secretion of patients during operation had same(bacteria.) No bacteria growth was found in anesthetic machine and disposable virus/bacteria respiratory filter used after operation.The same bacteria as from buccal secretion were isolated from anesthetic machine in patients(without) using virus/bacteris respiratory filter.CONCLUSIONS The(results) showed the anesthetic machine is more easy to be contaminated by patients,and the reuse of anesthetic machine is an important factor for nosocomial(lower) respiratory infection after general anesthesia through trachea intubation.Intensifying periodic disinfection of(anesthetic) machine and using virus/bacteria respiratory filter can prevent contamination between anesthetic(machine) and patients and decrease nosocomial lower respiratory(infection) after operation.
