Olfactory stimulation may promote oral feeding in immature newborn: a randomized controlled trial
Insights
Olfactory stimulation with scents like anise or cinnamon may help premature newborns transition to oral feeding faster. This sensory intervention could potentially shorten hospital stays for these vulnerable infants.
Area of Science:
- Neonatology
- Sensory Neuroscience
Background:
- Premature newborns often face challenges with respiratory immaturity and oral feeding.
- Feeding tube dependence necessitates prolonged hospital stays until oral feeding performance improves.
Purpose of the Study:
- To investigate if olfactory stimulation accelerates the transition from tube feeding to satisfactory oral feeding in premature infants.
- To determine the impact of specific scents (anise, cinnamon) on feeding progression and hospital discharge duration.
Main Methods:
- A controlled, randomized study involving 50 premature newborns.
- Infants were randomly assigned to receive either odorless stimulation or olfactory stimulation (anise or cinnamon).
- The primary outcome measured was the duration of hospitalization.
Main Results:
- The olfactory stimulation group showed a trend towards earlier hospital discharge (average 3.4 days sooner).
- A statistically significant reduction in hospital stay was observed in more mature newborns within the study cohort (p < 0.05).
Conclusions:
- Olfactory stimulation shows promise as an adjunct therapy to enhance early feeding in premature infants.
- Sensory interventions targeting olfaction may play a role in optimizing care and reducing hospital length of stay for neonates.
Abstract:
Premature newborns have an increased mortality and morbidity due to respiratory immaturity and inefficient oral feeding performance. Transient assistance with feeding tubes until oral performance improves is required with consequent hospital admission. Based on a controlled and randomized study, we tested whether olfactory stimulation compared to odorless stimulation could accelerate the switch from feeding tube to satisfactory oral feeding. Fifty newborns were included and randomly assigned to either odorless or olfactory stimulation with anise or cinnamon. The main outcome measurement was the duration of the hospital stay. The odor-stimulated group could be discharged from hospital on average 3.4 days earlier than the control group (p = 0.12). When including only more mature newborns into the analysis (n = 39), the difference was statistically significant (p < 0.05). This trend emphasizes that olfaction may have its place in early feeding stimulation.
