Effect of Olfactory and Gustatory Stimulations on Preterm Neonates’ Feeding Progression and Sniffing Away Feeding Tube

Abstract

Prematurity is associated with feeding difficulties which remain a challenge for the neonatal nurses. Reaching full enteral feeding and increased weight are eligible criteria for sniffing away feeding tube and discharging from the Neonatal Intensive Care Unit (NICU). So, incorporating innovative olfactory and gustatory stimulations would enhance the preterm neonates' oral feeding abilities. Consequently, it leads to sniffing away the feeding tube, improve full enteral feeding and weight. Aim: The aim of the present study was to determine the effect of olfactory and gustatory stimulations on preterm neonates' feeding progression and sniffing away feeding tube. Research design: A quasi-experimental design was used.

Effect of Olfactory and Gustatory Stimulation on Premature Neonates ' Feeding Progression and Sniffing Away Feeding Tube

“…As a result, the cephalic phase response to digestion is not as stimulated, which can lead to feed intolerance. This was in harmony with (Arafa et al 2021) who reported that average length of time until complete sucking or sniffing among the premature neonates in both groups. Regarding growth parameters, the findings showed that, there were no statistically significant differences during tube feeding initiation regarding growth parameters that become statistically significant during oral feeding initiation between both groups.…”

“…This conclusion may be supported by the observation that the taste and smell of milk may increase salivation, digestion-related enzyme secretion during tube feeding, and the emission of hormones concerned with digestion, including insulin, ghrelin, leptin, and gastrin (Zolotukhin 2012). This was matched with (Arafa et al 2021) and(khodagholi et al 2018) who indicated that the premature in the study group reached full sucking one week earlier than those in control group. Furthermore, it was observed by (Shamsi et al 2014) and(Yildiz et al 2011) that the smell of mother's milk helped premature newborns attain full feeding quickly .…”

Effect of Continuous Olfactory Stimulation Using Breast Milk on Physiological Indices and Behavioral Responses of Preterm Neonates

“…2 (Suppl 1) ,May 2024 milk of mother triggers reflexes in the brain that enhance salivation, peristaltic movements, release of digestion hormones and enzymes, thereby starting the digestive process even before food reaches the stomach. These reflexes are referred to as the cephalic phase response and release appetite hormones in saliva.These salivary hormones are responsible for metabolism and increasing peristaltic movements (Arafa., Radwan., & Mohammed, 2021;Schaal etal., 2020 ;Gellrich et al, 2018). This finding was supported by Muelbert., Bloomfield., Pundir., Harding., & Pook.…”
