Abstract:
Objective:To improve accuracy of prediction amount of length of gastric tube placed through nose and reduce occurrence of adverse events thorough clinical observation of measurement of length of nasogastric tube placement in critically ill children.Methods:Using the convenient sampling method, critically ill children who were hospitalized and needed a nasogastric tube in Pediatric Intensive Care Unit (PICU) of Beijing Children's Hospital Affiliated to Capital Medical University were selected from April to September 2019. The prediction method of "nos-ear-xiphoid (NEX) increased by 5 cm" (NEX+5 cm) was adopted. The values of placed length in this study were collected and compared with those predicted by traditional measurement method (namely NEX) , improved "nose-ear-mid-umbilicus" (NEMU) and formula method.Results:A total of 52 critically ill children were enrolled in this study. The length of placed nasogastric tube was 31.5 (28.3, 35.8) cm, and 43 cases (82.7%) were determined to be qualified by X-ray. The length of gastric tube required to be placed in children was 27.0 (24.1, 31.0) cm according to the NEX method, and the length of gastric tube required to be placed in children was 26.1 (22.5, 29.0) cm measured by the formula method. Both were shorter than that measured by NEX+5 cm, and the differences were statistically significant ( P<0.01) . The NEMU method measured the length of gastric tube to be inserted into the child to be 31.0 (28.3, 36.0) cm. Compared with the length measured by NEX+5 cm, and the difference was not statistically significant ( P>0.05) . Conclusions:This study uses NEX+5 cm to predict the actual length of the gastric tube inserted through the nose. The accuracy is relatively high and the operation method is simple. It is necessary to consider individual differences in clinical applications, especially the large variability in infants and young children. After catheterization, abdominal ultrasound, X-ray and other auxiliary examination methods should be used to determine the location of catheterization, and individualized catheterization programs should be given to children according to different therapeutic objective.
