Effects of respiratory training on pulmonary function and circulatory function in patients after thoracotomy

Objective To investigate the effects of respiratory training on pulmonary function and circulatory function in 100 patients with thoracotomy. Methods From November 2016 to January 2017, 50 patients with thoracic surgery were selected as the control group, and from February to June 2017, 50 patients with thoracotomy were assigned to the experimental group. The control group were given postoperative rehabilitation guidance according to the routine nursing care, while the experimental group received standardized respiratory health education and breathing exercises such as slow and deep respiration, pursed lips breathing, cough training, respiratory training apparatus and so on. The differences of pulmonary function, circulation function and complications after operation were compared between the two groups. Results There were no statistical significance in the differences of vital capacity (VC) , forced expiratory volume in one second (FEV1) , forced expiratory volume in one second/forced vital capacity (FEV1/FVC) , maximum ventilatory volume (MVV) and respiratory rate between the two group before operation (P>0.05) . After operation, VC, FEV1, FEV1/FVC and MVV of both groups were significantly decreased, and the respiratory rate increased significantly (P 0.05) . After operation, MAP and heart rate increased, SaO2 decreased in both groups (P<0.05) , and MAP and heart rate of the experimental group were lower than those of the control group, SaO2 higher than the control group (P<0.05) . There was 1 case of postoperative atelectasis in the experimental group, with a complication incidence rate 2.00%. There were 3 cases of pulmonary infection, 3 cases of pulmonary atelectasis and 2 cases of respiratory failure. The complication incidence rate was 16.00%, thus the incidence of pulmonary complications after surgery in the experimental group was lower than that of the control group (P<0.05) . Conclusions Respiratory training can promote the recovery of pulmonary function and circulatory function in patients after thoracotomy, and reduce the incidence of complications. It is worth promotion in clinical practice. Key words: Thoracic surgical procedures; Respiratory therapy; Pulmonary circulation; Respiratory function test; Complications; Postoperative recovery
