| Objective: To systematically evaluate the impact of respiratory muscle training on patients who undergoing lung resection,and to provide a reference for the development of perioperative rehabilitation programs for lung cancer patients.Methods: We searched Pub Med,Embase,The Cochrane Library,Web of Science,Clinical Trials.gov,CNKI,Wanfang Database,VIP,CBM,Chinese Clinical Trial Registry for randomized controlled trials about the effect of respiratory muscle training on patients with lung cancer resection from inception to 30 June,2020.After importing the searched results into endnotes,we screened literatures based on the inclusion and exclusion criteria.Then we evaluated the quality of the screened literatures and use Rev Man5.4 to extract the data and analyze the data.Results: Finally,4 RCT researches were included in the meta-analysis,they were all published in English.The incidence of postoperative pulmonary complications was lower in the respiratory muscle training group than control group,and the difference is statistically significant [OR =0.24,95%CI(0.06,0.98);Z =1.98,P =0.05].The length of stay was similar between two groups,and no statistically significant difference between two groups [MD =-0.54,95%CI(-2.56,1.48);Z=0.53,P =0.60].In terms of maximum inspiratory pressure(MIP),compared with the control group,the respiratory muscle training group can improve postoperative MIP,and the difference is statistically significant [MD = 17.64,95% CI(6.04,29.24);Z =2.98,P =0.003].The FEV1,FVC was also similar between two groups,and no statistically significant difference between two groups: [MD=0.28,95%CI(-0.14,0.69);Z =1.29,P =0.20]、[MD =0.49,95%CI(-0.02,1.01);Z =1.88,P =0.06].Conclusions: The result of this meta-analysis show that respiratory muscle training can improve the postoperative pulmonary complications and maximum inspiratory pressure on patients who undergoing lung resection.It should be considered in the pulmonary rehabilitation plan. |
