Different nutritional methods have different effects on the newborns with high intestinal obstruction operation. This study is to explore the advantages of enteral nutrition support with transnasal indwelling jejunal nutrition tube (TIJNT).

Sixty newborns with high intestinal obstruction treated in Children ’s Hospital of Hebei Province from February 2016 to February 2018 were prospectively and randomly selected. All patients underwent high intestinal obstruction surgery and were divided into two groups according to envelope method, with 30 cases in each group: the control group were given parenteral nutrition support; the study group were given TIJNT. The changes of blood biochemical indexes (1 day, 7 days, 15 days and 1 month after operation), the recovery of intestinal function, the occurrence of postoperative complications, the changes of body mass, hospitalization time and costs between the two groups were compared. The growth and development of the two groups at 3 months after operation were recorded.

①There was no significant difference in preoperative hemoglobin between the two groups. Compared with preoperation, the hemoglobin levels of the two groups decreased 1 day, 7 days, 15 days and 1 month after operation (P<0.05). The hemoglobin levels in the study group were higher than those in the control group at 1 day and 7 days after operation (P<0.05). ②There were no significant differences in postoperative albumin and total protein between the two groups. Compared with preoperation, the levels of albumin and total protein in the two groups decreased 1 day, 7 days, 15 days and 1 month after operation (P<0.05). ③During the treatment period, the time to achieve total enteral nutrition, feeding up to 40 ml/3 h and the first defecation time in the study group were shorter than those in the control group (P<0.05).④The incidence of postoperative complications such as vomiting and abdominal distension in the study group (6.67%) was significantly lower than 26.67% in the control group ( χ²=4.320, P=0.038). ⑤Before treatment, there was no significant difference in body mass between the two groups. Compared to the control group, the study group was heavier, the length of hospital stay was shorter, and the hospitalization cost was less (P<0.05).

TIJNT can effectively consolidate the surgical treatment of high intestinal obstruction in the newborns, with fewer complications after surgery, which is beneficial to the recovery of neonatal intestinal function and has high clinical value.
