Objective  To observe the effect of the patented technology of a new type of nasal feeding device for enteral nutrition in patients with severe stroke.

  Methods  A total of 238 severe stroke patients receiving enteral nutrition were selected, and were randomly divided into observation group and control group, with 119 cases in each group. The control group applied conventional method to place nasal feeding materials, and the observation groups used a new type of nasal feeding device. The gastrointestinal symptoms, positive rate of stool culture, the ratios of patients with dropping and unplanned replacement of injection syringes, and the bacterial contamination of nasal feeding syringes were compared between the two groups.

  Results  There was a statistically significant difference in incidence of gastrointestinal diarrhea between the two groups (P < 0.05); the ratio of positive patients for stool culture in the observation group showed a significant difference compared with that in the control group (P < 0.05); the ratios of patients with dropping and unplanned replacement of injection syringes in the observation group were significantly lower than those in the control group (P < 0.05). The positive rates of bacteria detection in the control group after 48 and 72 h using nasal feeding syringe were higher than those of the observation groups (P < 0.05 or P < 0.01). The operative duration of nasal feeding in the observation groups was shorter than that of the control groups, but it showed no significant between-group difference (P>0.05).

  Conclusion  The new nasal feeding apparatus holder can reduce the breeding of bacteria in the syringes, reduce the incidence of diarrhea and improve the nuring efficiency.
