ABSTRACT
Objective:To explore the application effect of flipped classroom teaching combined with micro-classes and PBL in the training of refresher nurses.Methods:Using the cluster sampling method, 35 refresher nurses from March 2017 to February 2018 were collected as the control group, and 38 refresher nurses from March 2018 to February 2019 were included as the observation group. The control group received the theoretical knowledge training of respiratory specialty by traditional teaching method, and the observation group received theoretical knowledge training of respiratory specialty by using flipped classroom teaching combining micro-classes and PBL. Before and after the training, the special theory assessment with the same difficulty was carried out, and the clinical teaching evaluation was carried out after the training.Results:After the training, the special theory assessment scores of the observation group were significantly higher than those of the control group ( t=7.560, P<0.05), with significant differences. Compared with the control group, the clinical teaching evaluation scores of the nurses in the observation group were significantly improved ( t=24.657, P<0.05), with significant differences, especially in the nurses' learning attitude, learning ability, teaching style and teaching satisfaction scores. Conclusion:The flipped classroom teaching combining micro-classes and PBL can significantly improve the special theory assessment scores of refresher nurses, promote the internalization of specialized knowledge, turn to active learning from the passive mode, change the learning attitude of refresher nurses, improve their recognition of clinical teachers and realize teaching benefits as well as learning benefits.
ABSTRACT
Objective To systematically analyze the research trend of home non-invasive positive pressure ventilation in China. Methods The related literature in CBM database, CNKI database, Wanfang database and VIP database about home non-invasive positive pressure ventilation were reviewed and analyzed by Bibliometric. Results There were 214 articles retrieved, which had an increasing tendency.They were distributed in 135 kinds of journals and 28 provinces.The most research type was the experimental research(39.72%)and the research content focused on clinical effects of home non-invasive ventilation (47.67%). The average duration of researches was 12.33 months and the average interval for follow-up was 6.33 weeks. Conclusions Providing scientific and effective long-term medical support, optimizing the application process of home non-invasive ventilation and formulating scientific clinical standard should be the future research direction.
ABSTRACT
Objective To determine whether Nutritional Risk Screening 2002 (NRS2002) of admission independently predicts outcome of non-invasive positive pressure ventilation (NIPPV) in chronic obstructive pulmonary disease (COPD) patients during hypercapnic respiratory failure.Methods Patients with COPD presenting with hypercapnic respiratory failure at Sichuan University Hospital between December 2010 and May 2012 and receiving NIPPV were studied prospectively.NRS2002 was measured before NIV administration.233 patients met the inclusion criteria,with NIPPV failed in 71 cases and succeed in 162 cases.The patients were followed up till they were discharged.Results After multivariate Logistic regression,the items such as baseline PaCO2,NRS2002 score could predicted 76.4％ of the failure outcome.The area under the curve was 0.767.The positive predictive value was 35.23％.The negative predictive value was 84.21％.Conclusions We can predict the risk failure of NIPPV in patients with COPD and hypercapnic respiratory failure with NRS2002 score and baseline PaCO2,and adjust the treatment project according to the evaluation result.NRS2002 supply non-invasive and portable method for predicting the failure of NIPPV.
