Objective To investigate the clinical characteristics ,pathogenic bacteria detection rate and drug sensitivity situation of pulmonary infection in surgical trauma inpatients .Methods The characteristics ,pathogenic clinical examination and treatment method of pulmonary infection among traumatic inpatients in Fengdu County Hospital of Traditional Chinese Medicine from June 2013 to December 2014 were retrospectively analyzed .Results The clinical symptoms of pulmonary infection were usually atypical .
