Met...Objective: To investigate the effect of extracorporeal diaphragmatic pacing combined with noninvasive ventilators on the respiratory function and prognosis of chronic obstructive pulmonary disease (COPD) patients. Methods: A total of 50 COPD patients were selected between January 2023 to December 2023 and randomly grouped into an observation group and a control group, with 25 cases. The observation group was given extracorporeal diaphragm pacing combined with a noninvasive ventilator, while the control group was given a conventional treatment mode. After the treatment, the results of each index in the two groups were compared. Results: Compared with the diaphragm function indexes of the two groups, the data of the observation group were more dominant (P < 0.05). The rehospitalization rate of the observation group was lower than that of the control group (P < 0.05). The COPD assessment test (CAT) and mMRC (Modified Medical Research Council) Dyspnoea scale scores after treatment between the two groups were significantly different (P < 0.05). Compared with the control group, the lung function indexes of the observation group were more dominant (P < 0.05). Conclusion: Extracorporeal diaphragmatic pacing combined with a noninvasive ventilator promoted the improvement of the patient’s prognosis and improved their respiratory function.展开更多

Methods: Eligible patients undergoing thoracotomy for tumor were selected from the thoracic surgery at a level-A tertiary hospital between August 2021 and December 2021 and included in the control group and the observation group (40 patients in each group). To prevent two groups of patients from interacting with each other, the thoracic surgery ward I was distinguished as the control group, which was adopted by the routine instruction. Based on routine instruction, the thoracic surgery ward II conducted respiratory function exercise instruction by video combined with the teach-back method to compare the two groups’ compliance with respiratory function exercise, complication rates, and patient satisfaction. Results: The patient compliance with respiratory function exercise in the observation group was significantly higher (P < 0.05) and the rate of pulmonary complications in the observation group was lower (P < 0.05) than that in the control group, while the observation group had a high level of satisfaction (P Conclusion: Taking video combined with the teach-back method, an effective health education method, can improve the compliance of the respiratory function exercise of patients undergoing thoracotomy for tumor and promote the recovery of pulmonary function to reduce the incidence of postoperative pulmonary complications so as to improve patient satisfaction.展开更多

The aim of this study is to evaluate quantitative computed tomography (QCT) for predicting postoperative pulmonary function in patients with lung cancer. Methods The data of thirty-one patients with lung cancer who underwent both pulmonary functional tests and QCT scan before operations were collected. A CT program was used to quantify the volume of whole lung parenchyma with attenuation of -910 HU to -600 HU, which was defined as total functional lung volume (TFLV). Similarly, the volume of lung (lobes or segments) with attenuation of -910 HU to -600 HU was defined as regional functional lung volume (RFLV). Forced vital capacity (FVC), forced expiratory volume in first second (FEV_1), FVC% and FEV_1% (ratio to reference values of the matched population) were obtained from preoperational pulmonary functional tests. According to the formula: predicted FVC (pre-FVC)=preoperative FVC×[1-(RFLV/TFLV)]; predicted FEV_1 (pre-FEV_1)=preoperative FEV_1×[1-(RFLV/TFLV)], we obtained values of predicted FVC, predicted FEV_1, predicted FVC% (pre-FVC/reference values of the matched population), and predicted FEV_1% (pre-FEV_1/reference values of the matched population). The paired t test and Pearson correlation test were used to assess significance of differences and correlations between CT predicted values and postoperative measured results of FVC, FEV_1, FVC% and FEV_1%. Results QCT predicted values correlated well with postoperative FVC, FEV_1, FVC% and FEV_1% ( r =0.873, 0.809, 0.849 and 0.801 respectively, all P <0.01).Conclusions QCT is an effective and accurate way to predict postoperative pulmonary function in patients undergoing pulmonary resection, regardless of the patients’ preoperative pulmonary functional status.展开更多

文摘BACKGROUND Both pulmonary rehabilitation training and psychological care have been shown to have a positive effect on the postoperative recovery of patients with lung cancer.However,few studies have combined the two to explore their combined effect.Therefore,this study aimed to investigate the effects of pulmonary rehabil-itation training combined with psychological care on postoperative respiratory function and mental health in lung cancer patients.AIM To investigate effect of nursing on postoperative respiratory function and mental health of lung cancer patients.METHODS 122 cases of lung cancer patients who underwent surgical treatment in our hospital and were treated in our department from January 2022 to April 2023 were selected and randomly divided into the control group and observation group.The control group performed the routine care intervention.The obser-vation group was given pulmonary rehabilitation training and psychological care based on conventional nursing interventions.Forced expiratory volume,forced vital capacity.Maximum ventilatory volume(MVV)in one second was measured,and the patient's 6-min walking distance and dyspnoea index scale were used to assess the patient's respiratory condition.The Connor-Davidson resilience scale(CD-RISC),self-rating anxiety scale(SAS),and self-rating depression scale(SDS)were used to evaluate the mental health of the patients.RESULTS There was no difference between the two groups regarding age,gender,education level,surgical procedure,type of pathology,and treatment(P>0.05).After treatment,MVV,6-min walking distance,toughness,strength,optimism,and total CD-RISC scores were significantly higher in the observation group(P<0.05),dyspnoea scores,SAS,and SDS scores were substantially lower in the control group compared to the observation group(P<0.05).CONCLUSION Pulmonary rehabilitation training combined with psychological care for patients after lung cancer resection could improve lung function,enhance daily activities,effectively relieve negative emotions such as anxiety and depression,and reduce complications.
文摘Objective: To investigate the effect of extracorporeal diaphragmatic pacing combined with noninvasive ventilators on the respiratory function and prognosis of chronic obstructive pulmonary disease (COPD) patients. Methods: A total of 50 COPD patients were selected between January 2023 to December 2023 and randomly grouped into an observation group and a control group, with 25 cases. The observation group was given extracorporeal diaphragm pacing combined with a noninvasive ventilator, while the control group was given a conventional treatment mode. After the treatment, the results of each index in the two groups were compared. Results: Compared with the diaphragm function indexes of the two groups, the data of the observation group were more dominant (P < 0.05). The rehospitalization rate of the observation group was lower than that of the control group (P < 0.05). The COPD assessment test (CAT) and mMRC (Modified Medical Research Council) Dyspnoea scale scores after treatment between the two groups were significantly different (P < 0.05). Compared with the control group, the lung function indexes of the observation group were more dominant (P < 0.05).

文摘In previous studies,researchers have used singing to treat respiratory function in patients with spinal cord injury.However,few studies have examined the way in which vocal training affects respiratory neural plasticity in patients with spinal cord injury.Vocal respiratory training(VRT)is a type of vocal muscle-related treatment that is often a component of music therapy(MT)and focuses on strengthening respiratory muscles and improving lung function.In this randomized controlled study,we analyzed the therapeutic effects of VRT on respiratory dysfunction at 3 months after cervical spinal cord injury.Of an initial group of 37 patients,26 completed the music therapy intervention,which comprised five 30-minute sessions per week for 12 weeks.The intervention group(n=13)received VRT training delivered by professional certified music therapists.The control group(n=13)received respiratory physical therapy delivered by professional physical therapists.Compared with the control group,we observed a substantial increase in respiratory function in the intervention group after the 12-week intervention.Further,the nerve fiber bundles in the respiratory center in the medulla exhibited a trend towards increased diversification,with an increased number,path length,thickness,and density of nerve fiber bundles.These findings provide strong evidence for the effect of music therapeutic VRT on neural plasticity.This study was approved by the Ethics Committee of China Rehabilitation Research Center(approval No.2020-013-1)on April 1,2020,and was registered with the Chinese Clinical Trial Registry(registration No.Chi CTR2000037871)on September 2,2020.
文摘Objective: To explore the effect of video combined with the teach-back method on respiratory function exercise in patients undergoing tumor thoracotomy. Methods: Eligible patients undergoing thoracotomy for tumor were selected from the thoracic surgery at a level-A tertiary hospital between August 2021 and December 2021 and included in the control group and the observation group (40 patients in each group). To prevent two groups of patients from interacting with each other, the thoracic surgery ward I was distinguished as the control group, which was adopted by the routine instruction. Based on routine instruction, the thoracic surgery ward II conducted respiratory function exercise instruction by video combined with the teach-back method to compare the two groups’ compliance with respiratory function exercise, complication rates, and patient satisfaction. Results: The patient compliance with respiratory function exercise in the observation group was significantly higher (P < 0.05) and the rate of pulmonary complications in the observation group was lower (P < 0.05) than that in the control group, while the observation group had a high level of satisfaction (P Conclusion: Taking video combined with the teach-back method, an effective health education method, can improve the compliance of the respiratory function exercise of patients undergoing thoracotomy for tumor and promote the recovery of pulmonary function to reduce the incidence of postoperative pulmonary complications so as to improve patient satisfaction.

文摘BACKGROUND Mechanical ventilation can lead to the severe impairment of the metabolic pathway of alveolar surfactants,inactivating alveolar surfactants and significantly reducing lung-chest compliance.The cardiopulmonary function of elderly patients usually reduced to a certain extent,and there are lung complications after surgical anesthesia,just like lung barotrauma caused by mechanical ventilation,atelectasis and postoperative hypoxemia.AIM To investigate the effects of different positive end expiratory pressures(PEEPs)and tidal volumes(VTs)on respiratory function,the degree of the inflammatory response and hemodynamic indexes in patients undergoing surgery under general anesthesia.METHODS A total of 120 patients undergoing surgery for gastric or colon cancer under general anesthesia in Xinghua People's Hospital from January 2017 to January 2021 were randomly divided into Group A and Group B,with 60 cases in each group.The ventilation mode in Group A was VT(6.0 mL/kg)+PEEP(5.0 cmH_(2)O),while that in Group B was VT(6.0 mL/kg)+PEEP(8.0 cmH_(2)O).Blood gas parameters,respiratory mechanical parameters,inflammatory response indicators,hemodynamic indicators and related complications were compared between the two groups.RESULTS There were no significant differences in PaCO_(2),PaO_(2),oxygen or the examined indexes at T0 between group A and group B(P>0.05).The measured PaO_(2) value of patients in group A at T3 was higher than that in group B,and the difference was significant(P<0.05).There were no significant differences in peak airway pressure(P_(peak)),mean airway pressure or dynamic pulmonary compliance(Cdyn)at T0 between group A and group B(P>0.05).The measured P_(peak) value of patients in group A at T1 was higher than that in group B,and the difference was significant(P<0.05).The measured Cdyn value at T1 and T2 was greater than that in group B(P<0.05).Before surgery,there were no significant differences in tumor necrosis factor-α(TNF-α),interleukin(IL)-6 or IL-10 between group A and group B(P>0.05).After 4 h,the measured values of TNF-αand IL-6 in group A were lower than those in group B,and the differences were significant(P<0.05).The IL-10 Level in group A was higher than that in group B(P<0.05).At T0,there were no significant differences in cardiac output,cardiac index(CI),stroke volume index(SVI)or mean arterial pressure between group A and group B(P>0.05).The measured values of CI and SVI at T2 in patients in group A were higher than those in group B,and the differences were significant(P<0.05).CONCLUSION For patients undergoing surgery for gastric or colon cancer under general anesthesia,the VT(6.0 mL/kg)+PEEP(5.0 cmH_(2)O)regimen was more effective than the VT(6.0 mL/kg)+PEEP(8.0 cmH_(2)O)regimen in protecting the lung function and ventilatory function of patients,and it had better effects on maintaining hemodynamic stability and reducing inflammatory reactions.
文摘Severe acute respiratory syndrome (SARS) is an acute respiratory infectious disease caused by a novel coronavirus, firstly broke out in November 2002 in Guangdong and prevailed quickly in Beijing, Hong Kong, Taiwan and other regions of China. It was one of the most potential pandemic diseases and had affected more than 20 other countries.^(1,2) There have been a lot of resear-ches^(2-7) in terms of its etiology, epidemiology, pathogenesis, clinical characteristics, diagnostics, treatment and prevention, vaccines and so on.Along with control of the epidemic situation, a great number of SARS patients were in the recovery phase, therefore, we undertook a half-year follow-up investigation on their clinical, laboratory and image situations.
文摘Background At present, the therapy for patients with lung cancer that achieves a high rate of cure is surgical resection at an early stage of the disease. The aim of this study is to evaluate quantitative computed tomography (QCT) for predicting postoperative pulmonary function in patients with lung cancer. Methods The data of thirty-one patients with lung cancer who underwent both pulmonary functional tests and QCT scan before operations were collected. A CT program was used to quantify the volume of whole lung parenchyma with attenuation of -910 HU to -600 HU, which was defined as total functional lung volume (TFLV). Similarly, the volume of lung (lobes or segments) with attenuation of -910 HU to -600 HU was defined as regional functional lung volume (RFLV). Forced vital capacity (FVC), forced expiratory volume in first second (FEV_1), FVC% and FEV_1% (ratio to reference values of the matched population) were obtained from preoperational pulmonary functional tests. According to the formula: predicted FVC (pre-FVC)=preoperative FVC×[1-(RFLV/TFLV)]; predicted FEV_1 (pre-FEV_1)=preoperative FEV_1×[1-(RFLV/TFLV)], we obtained values of predicted FVC, predicted FEV_1, predicted FVC% (pre-FVC/reference values of the matched population), and predicted FEV_1% (pre-FEV_1/reference values of the matched population). The paired t test and Pearson correlation test were used to assess significance of differences and correlations between CT predicted values and postoperative measured results of FVC, FEV_1, FVC% and FEV_1%. Results QCT predicted values correlated well with postoperative FVC, FEV_1, FVC% and FEV_1% ( r =0.873, 0.809, 0.849 and 0.801 respectively, all P <0.01).Conclusions QCT is an effective and accurate way to predict postoperative pulmonary function in patients undergoing pulmonary resection, regardless of the patients’ preoperative pulmonary functional status.
文摘Respiratory health in the general population declines regardless of the presence of pulmonary diseases.Oxidative stress has been implicated as one of the mechanisms involved in respiratory dysfunction.This review was to evaluate studies that relate oxidative stress factors with pulmonary function among the general population without prior respiratory illnesses.The search yielded 54 citations.Twenty-one studies qualified for incorporation in this review.Owing to the heterogeneity of the review,studies were discussed based on identified oxidative stress factors responsible for pulmonary dysfunction.Oxidative stress biomarkers,including gene polymorphisms of nuclear factor erythroid 2-related factor 2,heme oxygenase 1,glutathione S transferase,superoxide dismutase,and lipid peroxidation products were involved in lung function decline.In addition,the antioxidant status of individuals in reference to dietary antioxidant intake and exposure to environmental pollutants affected oxidative stress and pulmonary function,as indicated by forced expired volume in one second,forced vital capacity,and forced expiratory flow at 25%-75%.This review indicated that oxidative stress is implicated in the gradual decline of lung function among the general population,and gene polymorphism along the antioxidant defense line and/or their interaction with air pollutants reduce lung function.Different polymorphic forms among individuals explain why the rate of lung function decline differs among people.Dietary antioxidants have respiratory health benefits in antioxidant gene polymorphic forms.Therefore,the genetic composition of an individual may be considered for monitoring and identifying people at risk of respiratory illnesses.

文摘Background:The interpretation of spirometry varies on different reference values.Older people are usually underrepresented in published predictive values.This study aimed at developing spirometric reference equations for elderly Chinese in Jinan aged 60-84 years and to compare them to previous equations.Methods:The project covered all of Jinan city,and the recruitment period lasted 9 months from January 1,2017 to September 30,2017,434 healthy people aged 60-84 years who had never smoked (226 females and 208 males) were recruited to undergo spirometry.Vital capacity (VC),forced VC (FVC),forced expiratory volume in 1 s (FEV1),FEV1/FVC,FEV1/VC,FEV6,peak expiratory flow,and forced expiratory flow at 25%,50%,75%,and 25-75% of FVC exhaled (FEF25%,FEF50%,FEF75%,and FEF25-75%) were analyzed.Reference equations for mean and the lower limit of normal (LLN) were derived using the lambda-mu-sigma method.Comparisons between new and previous equations were performed by paired t-test.Results:New reference equations were developed from the sample.The LLN of FEV1/FVC,FEF25-75% computed using the 2012-Global Lung Function Initiative (GLI) and 2006-Hong Kong equations were both lower than the new equations.The biggest degree of difference for FEV1/FVC was 19% (70.46% vs.59.29%,t =33.954,P 〈 0.01) and for maximal midexpiratory flow (MMEF,equals to FEF25-75%) was 22% (0.82 vs.0.67,t =21.303,P 〈 0.01).The 1990-North China and 2009-North China equations predicted higher mean values of FEV1/FVC and FEF25-75% than the present model.The biggest degrees of difference were-4% (78.31% vs.81.27%,t =-85.359,P 〈 0.01)and-60% (2.11 vs.4.68,t =-170.287,P 〈 0.01),respectively.Conclusions:The newly developed spirometric reference equations are applicable to elderly Chinese in Jinan.The 2012-GLI and 2006-Hong Kong equations may lead to missed diagnoses of obstructive ventilatory defects and the small airway dysfunction,while traditional linear equations for all ages may lead to overdiagnosis.
