Effect of gradual training methods of breathing function on pre-operative pulmonary-function of patients with scoliosis

Abstract

Objective To improve indexes of pre-operative pulmonary function and operative tolerance,as well as to avoid accidental risks during operation by using gradual training methods of breathing function for patients with scoliosis.Methods Totals of 70 patients with scoliosis from July 2011 to July 2012 were chosen and trained with gradual methods of breathing function for 7 to 10 days.One nurse was in charge of guidance,evaluation and recording.Indexes of pulmonary function,including breathing capacity,maximal ventilatory capacity and percentages among predicted value,were compared before and after training.Results Average maximal ventilatory capacity and training frequency were respectively (1 877.22 ± 672.21)ml and (320.60 ±123.40) times/d after training,both higher than (1 466.12 ± 720.10) ml and (102.40 ± 48.20) times/d before training,and the differences were statistically significant (t =4.02,6.88,respectively; P ＜ 0.01).There was no statistically significant difference of pulses and degree of blood oxygen saturation before and after training.Breathing capacity and its percentage among predicted value,maximal ventilatory capacity and its percentage among predicted value were respectively (2.48 ± 0.70) L,(70.40 ± 12.34) ％,(58.21 ± 10.01) L and (90.44 ± 15.40) ％ after training,all of which were higher than (1.80 ± 0.65) L,(62.34 ± 10.17) ％,(47.02 ± 11.32)L and (83.80 ± 13.20)％ before training,and the differences were statistically significant (t =3.51,2.88,4.15,3.33,respectively; P ＜ 0.01).Conclusions Gradual training methods of breathing function on patients with scoliosis can improve their pre-operative pulmonary function,which provides technical support for patients' adoption to operations,reduction of risks and further training of breathing function,thus worthy of promotion.
