Aim: To evaluate the improvement of feeding intolerance to premature infants by abdominal massage. Method: From January 2018 to January 2020, the basic data of 72 premature infants in the NICU of our hospital were collected by retrospective method, which was divided into an experimental group and control group, 36 cases ineach group. The infants in the experimental group received such intervention of abdominal massage with daily fixed time and fixed frequency, and the control group without abdominal massage. The gestational age, birth weight, sex was not statistically significant in the two groups. The outcome indexes of the two groups were evaluated including the length of stay, the weight beginning oral feeding, the weight reaching total oral feeding, the weight at discharge, transition time, time to recover to birth weight, the daily weight gain, gastric residue. Results: Data analysis by SPSS24.0 showed that the weight beginning oral feeding (P = 0.012), weight reaching total oral feeding (P = 0.014) and the mean times of gastric residue in the experimental group was statistically significant. But there was no significant difference in the length of stay, the weight at discharge, transition time, time to recover to birth weight, and the daily weight gain. Conclusion: Intervention of abdominal massage might promote the weight gain and improve the feeding intolerance in premature infants.
