90 preterm infants were randomly assigned to kangaroo care (skin-to-=skin, chest-to-chest)
group (n=50) or control (remained in incubator, prone (n=40) for a pretest period of 2- 3
hours, then fed, then KC group was placed in KC and control group remained in incubator for
a 2-3 hr test period. EEG measures of sleep, HR, and RR were taken. .
The neonatal intensive care unit (NICU) environment is not conducive to sleep, and infant
sleep in incubators is fragmented. Sleep contributes to brain maturation so interventions to
foster sleep are needed. During Kangaroo Care (KC) behavioral indicators of Quiet Sleep have
been observed but, not confirmed by objective electroencephalographic (EEG) analysis.The
purpose was to determine the effects of Kangaroo Care (KC) on EEG-based sleep using Nihon
Koden polysomnography and cardiorespiratory patterns by comparing KC sleep to incubator
sleep.. A randomized controlled study with 90 preterms (KC = 50; control = 40) in which KC
infants received 2-3 hours of KC between feeds after a comparable pretest period in an
incubator and control infants remained in an incubator during the 2-3 hour pretest and test
periods. In the incubator infants were inclined, prone, and nested; in KC infants were
inclined, prone, and chest-to-chest underneath a blanket. The medically stable preterm
infants were a mean 32 weeks postmenstrual age.
- Subjects whose five-minute APGARS were greater than 6, gestational age was 28 or more
weeks at birth, and whose testing weight was greater than 1000 grams were included.
- Infants with encephalopathy, intraventricular hemorrhage greater than grade II, white
matter lucencies on cranial ultrasound, seizures, meningitis, or congenital brain
malformations were excluded
