Objective　To study the application value of WeChat video teaching mode in clinical teaching of digestive endoscopy nurses. Methods　The study selected 126 nursing trainees taking an internship in the Department of Gastroenterology in our hospital from January 2018 to June 2020 as the teaching objects

and they were randomized into two groups

Control Group and Experimental group

with 63 cases in each group. The control group adopted traditional teaching and the experimental group took traditional teaching combined with WeChat video teaching. The internship time of both groups was 4 weeks. The scores of comprehensive ability assessment after practice were compared between the two groups

and the critical thinking ability scale and nursing students' clinical practice satisfaction scale were used to evaluate the critical thinking ability and satisfaction of practice nurses of the two groups before and after teaching. SPSS 19.0 was used for statistical analysis of the research data. Continuous　variables were expressed as (mean ± standard deviation)

t test was performed

categorical variables were expressed as percentage

four-grid test was conducted

and the test level was α=0.05. Results　The scores of comprehensive ability

theoretical knowledge and operation skills of the experimental group were significantly higher than those of the control group (P<0.05). After teaching

the scores of seeking truth

opening mind

systematization ability

analytical ability

curiosity

cognitive maturity and total scale score of the two groups were significantly higher than those before teaching (P<0.05)

and there was no significant difference in the score of thinking self-confidence before and after the teaching (P>0.05). The scores of seeking truth

opening mind

systematization ability

analytical ability

curiosity

cognitive maturity and total scale score of the experimental group were significantly higher than those of the control group (P<0.05)

and there was no significant difference in the score of thinking self-confidence between the two groups (P>0.05). The experimental group's practice management

practice environment

teaching content

practice effect score and total scale score were significantly higher than those of the control group (P<0.05)

and compared with the control group

the score of teaching quality was poorer

without significant differences (P>0.05). Conclusion The application of WeChat video teaching mode in clinical teaching of digestive endoscopy nurses can improve the performance and satisfaction of comprehensive ability assessment of practice nurses

and enhance their ability of critical thinking.
