三维振动排痰机的工作特性及在脊柱外科患者术后肺部并发症的应用效果评价OA

Objective:To analyze application effect of three-dimension(3D)-vibration expectoration machine in postoperative pulmonary complications of patients who underwent spinal surgery.Methods:Based on the principle of manual expectoration through pats back,a device consisting of main unit,handheld treatment head,treatment head of cushion type,and control software(version V1)was designed,which can realize expectoration for patients who undergo spinal surgery through generates vibration waves with specific frequency,amplitude and direction.A total of 62 patients who underwent spinal surgery at Meishan People's Hospital from October to December 2024 were retrospectively selected as research subjects.Using block randomization grouping method,the subjects were divided into the control group and the observation group as a ratio of 1 to 1,with 31 cases in each group.The control group received conventional expectoration method,while the observation group adopted 3D-vibration expectoration machine to implement expectoration.After treatment,the postoperative pulmonary complications,scores of respiratory difficulty,quality of life,and various indicators of lung function between the two groups were compared.Results:The incidences of postoperative pulmonary complications of control group and observation group were respectively 25.80%(8/31)and 6.45%(2/31),and the incidence of observation was significantly lower than that of control group(x2=4.29,P<0.05).There was no statistically significant difference in the score of respiratory difficulty between the two groups before treatment(P>0.05).After treatment,the score of respiratory difficulty(2.01±0.23)of observation group was significantly lower than that of control group,and the difference was statistically significant(t=22.422,P<0.05).After treatment,the score of Euro Qol five-dimensional questionnaire(E5Q),and the score of global rating of change scales(GRCS)of observation group were respectively(23.65±1.96)and(4.65±0.32),which were significantly higher than those of control group(t=8.488,21.177,P<0.05).Before treatment,there were not significant differences in the forced vital capacity(FVC),first-second forced expiratory volume(FEV1),and the ratio FEV1 to FVC(FEV1/FVC)between the two groups(P>0.05).After treatment,the FVC,FEV1,and FEV1/FVC of observation group were respectively(3.65±0.12)L,(1.95±0.10)L,and(59.36±.105)%,which were significantly higher than those of control group,and the differences were statistically significant(t=19.023,10.254,11.254,P<0.05).Conclusion:The development and practical application of the 3D-vibration expectoration machine can significantly decrease the incidence of postoperative pulmonary complications of patients who undergo spinal surgery,and reduce the risk of respiratory difficulty of patients,and enhance the quality of life of patients,and improve the indicators of lung functions.
