Evidence summary of the method for measuring the length of nasogastric tube insertion / 中国实用护理杂志

ABSTRACT

Objective:To systematically retrieve, evaluate and summarize the research evidence on the measurement method of adult nasogastric tube indwelling length and provide a basis for clinical nursing practice.Methods:To search for Cochrane Library(CD-SR, DARE), Joanna Briggs(JBI), PubMed (MEDLINE), Web of Science electronic database, China Biomedical Literature Database (CBM), Wanfang Database, China Knowledge Network from the establishment of the database to December 2018. Two researchers independently evaluated the quality of the literature and extracted the data.Results:A total of 9 articles were included in the study. The recommended anatomical landmarks for measuring the length of the inserted gastric tube included XNE, NEX, XJN, Hanson method, GWNUF model, earlobe to xiphoid to navel-nose tip to earlobe NEX 10 cm. The tip of the nasogastric tube and all its lateral hole locations obtained by the Hanson method, the GWNUF model, and the XEN 10 cm method were more likely to be located in the stomach.Conclusion:Although NEX is an external measurement method that is widely used in clinical practice, it has proven to be insufficiently accurate and has considerable risks. Therefore, the method of measuring the length of the nasogastric tube insertion should be carefully selected for teaching or use in practice.
