Effects of breathing exercise on preoperative pulmonary function in adolescent scoliosis patients / 中国组织工程研究

ABSTRACT

BACKGROUND: Acute respiratory insufficiency is common complication of surgical treatment of adolescent scoliosis patients. The preventive effects of breathing exercise before surgery is still uncertain.OBJECTIVE: To explore the feasibility and efficacy of breathing exercises for scoliosis patients before operation.DESIGN: Nonrandomized cross sectional study.SETTING, PARTICIPANTS and METHODS: Totally 35 hospitalized kids with scoliosis and pulmonary dysfunction aged from 9 to 15 years old were selected from Shanghai Changhai Hospital. A set of breathing exercise including which included pursed lip breathing, abdominal breathing, diaphragmatic breathing and blowing balloon was performed to these patients one week before surgery. The changes of pulmonary function were recorded and compared before and after exercises.MAIN OUTCOME MEASURES: The change of vital capacity, lung capacity, forced ventilation capacity(FVC), maximal ventilation volume(MVV) before and after breath exercises.RESULTS: All sorts of indes are improved comparing with those before exercises. The vital capacity, lung capacity, FVC and MVV were greatly improved from(1.77 ±0. 36), (2.67 ±0. 84), (2.07 ±0.46), (52.5 ± 14.0) L before exercises to(2.65 ±0. 29), (3.56 ±0.79), (2.41 ±0.41), (70. 1 ± 17.0) L respectively( t = 3.63 - 11.28, P < 0.01).CONCLUSION: Preoperative breathing exercises can improve the pulmonary functions of kids with scoliosis and improve their tolerance to surgery and prevent the postoperative respiratory insufficiency.
