Application of modified postural drainage in treating stubborn pulmonary infection after cardiothoracic surgery

Objective To explore application effect of modified postural drainage on treating stubborn pulmonary infection after cardiothoracic surgery.Methods Totals of 88 patients with stubborn pulmonary infection after cardiothoracic surgery were chosen,and randomly divided into the experimental group (n =47)and the control group (n =41).The control group received conventional drug therapy and nutritional support treatment,while the experimental group received modified postural drainage method in addition.Two groups'treating time,rehabilitation conditions,antibiotic use time were compared.Results Fifteen days after modified postural drainage,41 cases in the experimental group and 21 cases in the control group had smaller lesion,and the difference was statistically significant (x2 =32.19,P ＜ 0.01).The score of physical function,physical role,general health condition,vitality,and psychological health in SF-36 scale was respectively (52.22 ±9.27),(56.87 ± 9.22),(58.69 ± 7.54),(49.33 ± 8.25),(53.28 ± 7.89) in the experimental group,and (41.54 ± 10.11),(44.28 ± 10.41),(45.22 ± 8.29),(33.21 ± 9.57),(42.74 ± 8.03) in the control group,and the differences were statistically significant (t =3.45,2.65,4.21,3.54,2.58,respectively;P ＜0.05).There were no obvious adverse reactions in both groups.Conclusions Modified postural drainage,better than simple drug therapy,can promote the recovery of stubborn pulmonary infection after cardiothoracic surgery.
