ABSTRACT
Objective:To investigate the correlation between single-breath counting (SBC) and standard measures of pulmonary function in patients with spinal cord injury, to evaluate the value for predicting pulmonary function. Methods:Forty-two patients (24 with cervical injury and 18 with thoracic injury) were selected from October, 2018 to February, 2019 in outpatients and inpatients. SBC and standard laboratory spirometer tests were performed separately. The correlation of the outcome of SBC and lung function indicators including forced vital capacity (FVC), forced respiratory capacity in the first second (FEV1), FEV1/FVC, slow expiratory vital capacity (EVC) and all the predicted values on the percentage (%pred) were analyzed. A receiver operating characteristic (ROC) curve was constructed according to the lung function classification criteria. Results:The outcome of SBS was correlated with FVC, EVC as well as the percentage of predicted values (r = 0.723 to 0.760, P < 0.01 for the whole patients; r = 0.549 to 0.657, P < 0.01 for cervical ones; r = 0.623 to 0.847, P < 0.01 for thoracic ones), and was also correlated with FEV1 as well as the percentage of predicted values (r = 0.622 to 0.760, P < 0.01 for whole patients and cervical ones). The area under the ROC curve was 0.864 to 0.941. Conclusion:There is a good correlation between SBC and standard lung function for patients with spinal cord injury, suggesting an assistive diagnostic value for patients with reduced lung function.
ABSTRACT
Objective To observe the short-term effect of comprehensive pulmonary exercise on the impaired respiratory function of convalescence patients suffered from cervical spinal cord injury. Methods From November, 2011 to December, 2016, 100 patients with cervical spinal cord injury (C3-C6,ASIA A-D) were randomly divided into control group(n=50)and observation group(n=50).The control group received rou-tine rehabilitation training,and the observation group added comprehensive pulmonary exercise.They were ex-amined with forced vital capacity(FVC),forced expiratory volume in first second(FEV1),maximum expiratory flow rate with remaining 25% vital capacity (MEF25%) and maximum ventilation volume (MVV) before and two months after intervention. Results The FVC,FEV1,MEF25% and MVV improved significantly in the observation group(t>4.110,P<0.001),and the D-value was more in the observation group than in the control group before and after intervention(t>4.390, P<0.001). Conclusion Comprehensive pulmonary exercise has short-term effect on pulmonary function in convalescent patients survived from cervical spinal cord injury.
