Application of CBL Teaching Method in Pulmonary Ultrasound Teaching
Objective To analyze the value of case-based learning(CBL)in intensive care training in the intensive-care unit of pulmonary ultrasound in cardiac surgery.Methods From January to June 2022,50 intensive care nurses were selected from the department of cardiothoracic intensive care unit,Guangdong Provincial People's Hospital,Southern Medical University during this period.Based on the different regions of the nurses,they were divided into control group and study group,with 25 nurses in each group.The conventional teaching method was used in the control group,and the CBL teaching method was used in the research group.The recognition of ultrasonic signs and examination scores of the two groups were compared.Results Compared with the control group,the study group had a higher recognition rate of ultrasonic signs,especially in some difficult-to-understand ultrasonic signs,such as bat sign(P=0.027),c-line sign(P=0.002),stratospheric sign(P=0.005),there were significant differences between the two groups(P<0.05).The score of skill assessment in the study group was higher than that in the control group,the difference was statistically significant(P<0.001).Conclusion In the teaching of pulmonary ultrasound in intensive-care unit of cardiac surgery,the implementation of CBL teaching method is of great value to nurses,which can significantly improve their mastery of pulmonary ultrasound knowledge and skills.
