Abstract: Objective To explore the best evidence-based interventions for nasal tube feeding and unplanned extubation in inpatients and to evaluate the efficacy. Methods With the JBI clinical Evidence Practice model, the Cochrane Library Pubmed for Health and Care Excellence (NICE) and the National Guideline Clearinghouse (NGC)were searched to obtain the best evidence on unplanned extubation.The quality of evidence was evaluated by using the JBI2014 version of evidence grading system and then the evidence was converted into clinical review standards. Results After the application of evidence,the rate of unplanned extubation was lower than before(P<0.05).The qualified rate of tube fixing was obviously improved(P<0.05). The examination score of nurses in unplanned extubation training was improved from 84.23±17.01 to 95.02±7.32, and the difference was statistically significant(P<0.05). The 7 review indicators showed that the execution rate of nurses increased from 0~28% at the baseline review to 78.56%~100% after the application of evidence, showing statistical significance (P<0.05). Conclusion Evidence-based unplanned extubation through nasal tube feeding can effectively standardize the management and nursing practice of gastric tube, improve nursing staff's knowledge of gastric tube, and reduce the rate of unplanned extubation.
