Exploration the Stress Responses of Preterm Infant
in NICU. Edition No. 1
VDM Publishing House, May 2009, Pages: 136
The purpose of this exploratory descriptive study
was to examine relationships between stress
physiological signals and stress behaviors in
preterm infants during periods of environmental
stress. Research used a prospective, quasi-
experimental repeated-measuring method to examine
the research variables in one group of preterm
infants. Measurements of research variables were
recorded every two minutes during two 60-minute
observation periods and conducted over two days. The
multiple linear regression of GEE methods were used
to approach the relationships between stress
physiological signals and stress behavioral
responses. The convenience samples were preterm
infants and all research subjects were in the
incubator in NICU or sick baby room. Research data
were 4164 observations of 37 preterm infants. There
was a statistically significant relationship between
nine stress behavioral responses and changes in
heart rate and respiratory rate. There was also a
statistically significant relationship between 11
stress behavioral responses and changes in oxygen
saturation level.
