“…Emergence of organized SW cycling likely requires complex interactions among neuronal networks that may be vulnerable to perinatal brain injury. 33 Our findings are compatible with the idea that brain lesions can affect the development of these complex connections and can lead to delay in maturation of state cycling.…”

OBJECTIVE To evaluate the association between qualitative and quantitative amplitude-integrated EEG (aEEG) measures at term equivalent age (TEA) and brain injury on magnetic resonance imaging (MRI) in preterm infants. STUDY DESIGN A cohort of premature infants born at < 30 weeks of gestation and with moderate-to-severe MRI injury on a TEA MRI scan was identified. A contemporaneous group of gestational age-matched control infants also born at < 30 weeks of gestation with none/mild injury on MRI was also recruited. Quantitative aEEG measures, including maximum and minimum amplitudes, bandwidth span and spectral edge frequency (SEF90), were calculated using an offline software package. The aEEG recordings were qualitatively scored using the Burdjalov system. MRI scans, performed on the same day as aEEG, occurred at a mean postmenstrual age of 38.0 (range 37 to 42) weeks and were scored for abnormality in a blinded manner using an established MRI scoring system. RESULTS Twenty-eight (46.7%) infants had a normal MRI or mild brain abnormality, while 32 (53.3%) infants had moderate-to-severe brain abnormality. Univariate regression analysis demonstrated an association between severity of brain abnormality and quantitative measures of left and right SEF90 and bandwidth span (β = − 0.38, − 0.40 and 0.30, respectively) and qualitative measures of cyclicity, continuity and total Burdjalov score (β = − 0.10, − 0.14 and −0.12, respectively). After correcting for confounding variables, the relationship between MRI abnormality score and aEEG measures of SEF90, bandwidth span and Burdjalov score remained significant. CONCLUSION Brain abnormalities on MRI at TEA in premature infants are associated with abnormalities on term aEEG measures, suggesting that anatomical brain injury may contribute to delay in functional brain maturation as assessed using aEEG.

“…In the womb, the fetus floats in a dark pool of warm, massaging fluid in which the infant is effortlessly suspended in a flexed position. Warmth maximizes weight gain and promotes the sleep necessary for brain development (Scher, 2011). The mother's heart beat is a familiar and soothing background, her voice adds new sounds and cadence, her unique scent emanates from amniotic fluid, and the fetus is rocked with each maternal breath-these stimuli assist the fetus in recognizing mother.…”

“…Sleep provides respite from any stressful and/ or discomforting situation (Scher, 2011), so sleep can be considered a physiologic aspect of comfort (Kolcaba & DiMarco, 2005). Sleep is also necessary for brain growth and development, especially during the first 3 critical years of life (Scher, 2011). Sleep in SSC is profoundly different from sleep in an incubator or cot.…”

Birth and the newborn environment are stressful, especially for preterm infants who have to contend with medical conditions while adapting to the extrauterine world. Therefore, preterm newborns are excellent candidates for comforting measures. Skin-to-skin contact is the best way to provide comfort in several of the realms of Kolcaba's Comfort Theory. Evidence suggests that skin-to-skin contact between the mother and newborn changes the discomforting newborn environment into one that is profoundly comforting. Skin-to-skin contact promotes infant physiologic stability and warmth, helps in organizing infant sleep, reduces stress and pain, and makes breast milk readily available. Comfort to the newborn can be effectively accomplished by skin-to-skin contact.
