Gastroscopy-guided placement of intranasal jejunum nutrient canal and analysis of nutrient absorption efficiency

This study investigated and analyzed using both a pair of clamping pliers to place intranasal-jejunum nutrient canal under the guidance of gastroscope and using a guide wire to place the canal under the guidance of gastroscope. Ninety critically ill patients were randomly divided into a control (n=45) and an observation (n=45) group. The observation group had the intranasal-jejunum nutrient canal placed under the guidance of gastroscope by using a pair of clamping pliers while patients in the control group had the same canal placed under the guidance of gastroscope but using the guide wire. An intergroup comparison was conducted on the success rate of intranasal-jejunum nutrient canal placement and the incidence of complications. The results showed that the comparison yielded no significant difference in the success rate between observation (95.56%) and control (97.78%) groups (P＞0.05). When compared with control group, the A/G ratio and BMI level in the observation group increased significantly (P＞0.05). The intergroup comparison also yielded no significant difference in the incidence of complications. It was concluded that the method of gastroscopy-guided placement of intranasal jejunum nutrient canal produced better clinical results. The operating steps were simple and it had very low incidence of complications, therefore this method can be widely promoted for clinical practices.
