We examined the effects of breast milk smell on transition time from gavage to oral feeding and hospital stay in premature infants. There were 92 premature infants younger than 33 weeks who were randomly selected and sequentially allocated to the following groups: control (n = 46) and intervention (n = 46). This experimental study was undertaken in 2 neonatal intensive care units located in Vali Asr and Jamee Zanan educational hospitals in Tehran, Iran. We collected data from April 6 until September 6, 2013, over 4.5 months. Participants’ demographic data were extracted from their medical records. The findings of the study indicated that the use of an impregnated pad with breast milk, which was used for olfactory stimulation, reduced premature infants’ transition feeding time by 10 days in the intervention group compared with the control group. The length of hospitalization was also reduced by 12 days in the intervention group compared with the control group. The study results suggested that neonatal intensive care unit nurses should train mothers in the performance of this simple, inexpensive method to improve the quality of care provided to premature infants and reduce feeding transition time from gavage to oral feeding.
