Abstract:Objective To investigate the effect of preoperative incentive spirometry education on pulmonary function after total hip replacement.Methods 60 patients undergoing hip replacement were randomly divided into incentive spirometry education group (30 cases),the routine nursing group (30 cases).Weobserved pulmonary function recovery time,complications of lung and non-pulmonary complications.Results The time of IS return to preoperative volume was (9.3±2.1)hours inexperiment group,and(15.4±2.8)hours in control group,there was significant difference between two groups (P=0.03),Inexperiment group,there was 1 case of pulmonary complications in experimentgroup,and 3 cases in control gourp.There was no significant differences between two groups (P=0.604).In experiment group,5 cases hadnon-pulmonary complication,and 8 cases in control group,there was no significant differences between two groups (P=0.530).0.5 hours after operation,arterial oxygen saturation in experiment group was (94±0.8)%,and (92.5±0.96)% in the control group,the difference was statistically significant (P=0.041).Conclusion Preoperativeincentive spirometry education can promote the recovery of pulmonary function of patients with total hip replacement,but it still needs further study with large samples to assess effects on pulmonary complications and non pulmonary complications.
