Olfactory Stimulation for Very Low Birth Weight Infants

The Influence of Olfactory Stimulation of Breast Milk on the Stability of Physiological Indicators of Very Low Birth Weight Infants

This is a RCT study examining whether odor administration to mothers of very low birth weight infants promotes stabilization of vital signs compared with common nursing care. This study used breast milk olfactory stimuli familiar and liked by premature infants to understand the effects of olfactory stimuli on the physiological indicators of very low birth weight infants, the effect on the time of complete enteral nutrition, and the effects on growth and development of very low birth weight infants.

Fluctuations in vital signs of very low birth weight infants may lead to poor prognosis. Research Objectives:

To evaluate the effect of olfactory stimulation of breast milk on the stability of physiological indexes of very low birth weight infants Subjects: Very low birth weight infants whose gestational age are less than 32 weeks.

Inclusion Criteria:

• Gestational age at birth <32 weeks;

• Admission to hospital within 24 hours after birth;
• Mother can provide breast milk

Exclusion Criteria:

• Severe congenital malformations;
• Complicated congenital heart disease;
• Congenital gastrointestinal disease;
