The olfactory sensitivity of the premature newborn

  title={The olfactory sensitivity of the premature newborn},
  author={L. Marliera and C. Gauglerb and D. Astrucb and J. Messerb},
This document reviews the main data relating to the structural and functional organisation of olfactory perception in the premature newborn. The chemoreceptive systems (main olfactory, trigeminal, vomeronasal and terminal systems) develop in different chronological orders but quite at very early stage during ontogeny. The premature newborn, despite being immature, has been shown to react to a wide variety of olfactory stimuli. Moreover, the infant seems capable of distinguishing odours of… Expand
Neonatal responsiveness to the odor of amniotic fluid.
It was observed that one drop was enough to trigger a response, even at 6 hours of life, and apparently, babies are able to detect minimum amounts of amniotic fluid and habituate the response with repeated exposure during their first hours oflife. Expand
Olfactory stimulation may promote oral feeding in immature newborn: a randomized controlled trial
The trend emphasizes that olfaction may have its place in early feeding stimulation and whether olfactory stimulation compared to odorless stimulation could accelerate the switch from feeding tube to satisfactory oral feeding. Expand
Ontogeny of perception of maternal and nosocomial stimuli in infants
Preterm born infants in neonatal units experience unusual sensory inputs that can shape and nurture their developing brains differently from full-term healthy newborn infants. To improve the care ofExpand
Cortical Responses to Alien Odors in Newborns: An fNIRS Study
VPT and FT infants showed trigeminal sensitivity after exposure to alien odors that induce pain, potentially affecting the wiring of the neuronal circuits of the newborn brain. Expand
Protocol of controlled odorant stimulation for reducing apnoeic episodes in premature newborns: a randomised open-label Latin-square study with independent evaluation of the main endpoint (PREMODEUR)
The objective of the present protocol is to reduce the occurrence of apnoeic episodes in premature newborns by controlled odorant stimulation added to current pharmacological treatments. Expand
Smell and Taste to Improve Nutrition in Very Preterm Infants: A Randomized Controlled Pilot Trial
Data indicate that the smell and taste of milk may improve milk tolerance and weight in preterm infants and merits a larger trial powered to detect important outcomes. Expand
Enhanced kangaroo mother care for heel lance in preterm neonates: a crossover trial
The sensorial stimulations from skin-to-skin contact that include tactile, olfactory sensations from the mother are sufficient to decrease pain response in premature neonates. Expand
Exploring the olfactory environment of premature newborns: a French survey of health care and cleaning products used in neonatal units
Aim:  To assess the main determinants of the newborn’s nosocomial olfactory environment and to establish a methodology to assess these determinants more fully in mothers and babies. Expand
Respuesta neonatal frente al olor del líquido amniótico
Aparentemente, durante las primeras horas los bebés pueden detectar mínimas cantidades de líquido amniótico and habitúan su respuesta con la exposición repetida y habitudan su responses a la sexta hora oferta de vida. Expand
Neonatal cortical perceptions of maternal breast odours: A fNIRS study
The aim was to determine whether preterm and full‐term newborn infants could process maternal breast odour at a cortical level.


Facial and Autonomic Responses to Biological and Artificial Olfactory Stimuli in Human Neonates Re-Examining Early Hedonic Discrimination of Odors
No convincing evidence was obtained that neonates discriminated the hedonic valence of odors within the same perceptual space as adults, but neonates evinced a differential pattern of respiratory responding to the presentation of milk odors according to the mode of feeding, suggesting that early olfactory discrimination may be mediated by stimuli with high ecological salience. Expand
Cerebral Hemodynamic Response to Unpleasant Odors in the Preterm Newborn Measured by Near-Infrared Spectroscopy
It is concluded that cortical hemodynamic modifications occur in the preterm newborn after exposure to preparations commonly used in the neonatal intensive care unit and a lateralization seems to occur in processing unpleasant olfactory cues. Expand
Olfactory Familiarization and Discrimination in Preterm and Full-Term Newborns
The purpose of this study was to observe olfactory detection and discrimination in preterm and full-term newborns. Infants were familiarized for 10 trials with either vanillin or anethole. On eachExpand
Olfactory Stimulation Prevents Apnea in Premature Newborns
The introduction of a pleasant odor in the incubator is of therapeutic value in the treatment of apneas unresponsive to caffeine and doxapram, and this diminution affected all the infants. Expand
Olfactory experience mediates response to pain in preterm newborns.
Infants who were presented with a familiar odor during venipuncture showed no significant increase in crying and grimacing during the procedure compared to baseline levels, which is consistent with a body of evidence on early memory and olfactory competence in fetuses and newborns. Expand
Olfactory reflexes in the newborn infant.

Olfactory reflexes were regularly elicited in normal infants after 32 weeks' gestation, but some premature infants as young as 28 weeks also responded, and they are useful in excluding cerebral malformations associated with agenesis of the olfactory bulbs. Expand
[Development of human olfactory receptors].
At the 11th week of the development, completely differentiated olfactory cells were found, which are suggested to be capable of normal Olfactory performance. Expand
Trigeminal perception of odorant quality in congenitally anosmic subjects.
The present results suggest that the nasal trigeminal system may contribute significantly to the perception of odor quality, except in discriminating between acetic acid and menthol. Expand
Development of olfactory and related structures in staged human embryos

  • 2004
The staged sequence of development of the olfactory and related structures has been established from the serially sectioned human embryos of the Carnegie collection, from stage 11 to stage 23, and theOlfactory strands are well individualized, and ofactory and terminal-vomeronasal fibers are easily distinguishable.

Clinical Usefulness of Maternal Odor in Newborns: Soothing and Feeding Preparatory Responses
The results suggest that the practice of presenting the mother’s odor to a distressed infant is of clinical usefulness since it was capable of attenuating crying and a role for maternal odor with respect to feeding is characterized. Expand
