ABSTRACT=<sec><title>Background</title><p>Influenced by individual differences, the depth of gastric tube placement is often different. Clinically, it is necessary to seek a simple and accurate gastric tube insertion scheme to improve the clinical efficacy of indwelling gastric tube.</p></sec><sec><title>Materials and Methods</title><p>A total of 100 adult patients undergoing transesophageal manometry <italic>via</italic> nose were included in the study. The <italic>in vivo</italic> length (NCL) of apex-cardia was measured. At the same time, we entered our institutional database, summarized the clinical data of 100 patients, and analyzed the risk factors affecting NCL using stepwise regression analysis.</p></sec><sec><title>Results</title><p>The NCL length scores of patients with different gender, age, marital status, height, weight, BMI, sitting height, sternum length, hairline-xiphoid process, nose tip-earlobe-xiphoid process and earlobe-xiphoid process were statistically significant (<italic>P</italic> &lt; 0.05). Height, sitting height, gender, BMI and earlobe-xiphoid process were the factors that affected the NCL length score (<italic>P</italic> &lt; 0.05). The prediction equation of the estimation method of gastric tube insertion length was as follows: NCL length score = 39.907 + 2.909× height +0.865× sitting height. Adjust <italic>R</italic><sup>2</sup> to 0.506. NCL was positively correlated with height and sitting height. Among them, the correlation with height (<italic>r </italic>= 0.711, <italic>P </italic>&lt; 0.001) and sitting height (<italic>r </italic>= 0.397, <italic>P </italic>&lt; 0.001).</p></sec><sec><title>Conclusion</title><p>Height, sitting height, gender, BMI and earlobe-xiphoid process were the factors that affected the score of NCL length. There was a significant positive correlation between height, sitting height and NCL length. On this basis, the length of nasogastric tube insertion could be estimated.</p></sec>
