Etiological analysis and intervention of postoperative respiratory failure in patients with lung cancer / 解放军医学杂志

ABSTRACT

Objective To explore the causes,prevention and treatment of postoperative respiratory failure in patients with lung cancer.Methods The clinical data of 659 patients,admitted in Changzheng Hospital from Jan.2000 to Dec.2006,with lung cancer and suffered from postoperative respiratory failure were analyzed retrospectively.Preoperative lung function,past medical history,the etiology and preventive procedures,and the treatment methods for postoperative respiratory failure were also reviewed.Results Postoperative respiratory failure was occurred in 42 of 659 cases,the incidence was 6.4%,and all the 42 cases occurred in 1 to 5 days after operation.The major etiopathogenisis of postoperative respiratory failure included respiratory infection,bronchial asthma,operative wound,postoperative incision pain,preoperative cardiopulmonary dysfunction,etc.The respiratory failure was controlled in 37 of the 42 cases by mechanical ventilation and symptomatic treatment.Two cases died of multiple organ failure,another 2 cases died of respiratory distress syndrome and 1 case died of severe respiratory tract infection,the mortality was 11.9%.The preoperative lung function indexes of patients with postoperative respiratory failure were significantly lower than that of those patients without postoperative respiratory failure(P
