Incentive spirometry versus routine chest physiotherapy for prevention of pulmonary complications after abdominal surgery
We entered 876 patients into a clinical trial aim ed at preventing pulmonary complications after abdominal surgery . Patients either received conventional chest physiotherapy or were encouraged to perform maximal inspiratory manoeuvres for 5 min during each hour while awake , using an incentive spirometer . The incidence of pulmonary complications did not differ significantly between the groups : incentive spirometry 68 of 431 ( 15.8 % , 95 % CI 14.0 - 17.6 % ) , and chest physiotherapy 68 of 445 ( 15.3 % , CI 13.6 - 17.0 % ) . Nor was there a difference between the groups in the incidence of positive clinical signs , pyrexia , abnormal chest radiographs , pathogens in sputum , respiratory failure ( PO2 less than 60 mm Hg ) , or length of stay in hospital . We conclude that prophylactic incentive spirometry and chest physiotherapy are of equivalent clinical efficacy in the general management of patients undergoing abdominal surgery
