The Effect of Non-nutritive Sucking on Mother's Finger on Feeding Tolerance and Attainment of Independent Oral Feeding in Preterm Infants: A Randomized Trial

Background Non-nutritive sucking is part of the initial development process in preterm infants that may speed up the transition from the tube to oral feeding. The aim of this study was to evaluate the effect of non-nutritive sucking on mother's finger on feeding tolerance and attainment of independent oral feeding in preterm infants. Materials and Methods This single blind clinical trial was conducted on 40 preterm infants admitted to the NICU of Imam Reza Hospital, Kermanshah in 2017. In the intervention group, non-nutritive sucking was performed on the mother's finger three times a day for 10 days during the first 10 minutes of gavage. Then, the gastric residual volume, time to achieve independent oral feeding, length of hospitalization, and weight at discharge were measured. The data was analyzed using SPSS software version 24.0. Results: According to the results, the mean of gastric residual volume was less in the intervention group (0.65±0.33) compared to the control group (2.30±0.71) (P
