Abstract
OBJECTIVE To know the risk factors about lung infection in patients after tracheal intubation general anesthesia and take control measures.METHODS All the patients with tracheal intubation general anesthesia from Jan to Dec in 2007 were investigated retrospectively.RESULTS Among 2914 operation cases,471 cases were of tracheal intubation general anesthesia and 95 cases were infected(20.17%).The infection rate was 5.38%(24 hours) and 41.67%(24 hours).Sputum culture: G-bacteria accounted for 57.65%,G+ bacteria 28.83%,fungi(13.52%).CONCLUSIONS The infection rate increase with longer intubation time.Mechanical ventilation is a risk factor of lung infection.The measures to control infection include shortening intubation hours,reducing mechanical ventilation and strictly sterilization and isolation.
