ABSTRACT

OBJECTIVE To explore the risk factors of lower respiratory tract nosocomial infection in geriatrics patients after abdominal operation and the measures of prevention and control.METHODS The medical records of the 470 cases with abdominal operation from Jan 2003 to Sep 2006 were investigated retrospectively with prospective monitoring.RESULTS Among 470 cases,119 suffered from hospital infection,62 suffered from lower respiratory tract hospital infection,the infection rate being 13.19% and occupied 52.10% of the total number of the hospital infection in the abdominal operation.CONCLUSIONS Invasive operation,such as nasogastric tube,intubation,inhaling oxygen,sputum drawing out,cannulization,tracheotomy,and use of respirator after operation,lying in bed,vomit,using proton pump inhibitors,and underlying diseases are the causes of the lower respiratory tract hospital infection.To enhance the monitoring and control of the risk factors,we can decrease the rate of lower respiratory tract infection and mortality in geriatrics patients after abdominal operation.
