Impact of Breast Milk on Cortical Pain Response in Newborns
Study Details
Study Description
Brief Summary
Background:Newborns are exposed to painful procedures for many different reasons in the first days of their life. If pain is not relieved effectively in these newborns, neurodevelopmental and behavioral problems may occur in the short- and long-term.
Objective:This study is aimed to investigate the effects of breast milk on cortical pain response and behavioral response in newborns during heel-prick procedure.
Design: A prospective, randomized controlled trial was conducted on newborns born in a university hospital. Healthy-term newborns, undergoing heel blood sampling for newborn screening, were enrolled in the study. Infants were randomly assigned to study group with receive orally 2 ml breast milk (n=45) or a control group with no intervention (n=45) before the heel prick. A near-infrared spectroscopy device was used to monitor regional cerebral oxygen saturation (rScO2), while neonatal pain expression was assessed by Neonatal Pain, Agitation, and Sedation Scale (N-PASS). The rScO2 measure was the primary outcome, while the N-PASS score, heart rate, SaO2, and crying time were the secondary outcomes.

Detailed Description
During the first few days of life, newborns are exposed to painful and stressful procedures.1, 2 One of these is the metabolic disease screening test using the heel-prick procedures.3, 4 Newborn screening is crucial to detect several congenital genetic and metabolic disorders at an early stage for the earliest possible recognition and management of affected newborns and to prevent morbidity, mortality, and disabilities associated with inherited metabolic disorders5. Pain induced by these procedures is ineffectively prevented or inadequately treated1. Consequently, this may have short- and long-term negative effects on the pain response and neurodevelopmental outcomes.6, 7, 8 Thus, effectively identifying, assessing, and managing neonatal pain are crucial to minimizing its impact on the intermediate- and long-term outcomes in newborns.2, 9 Near-infrared spectroscopy (NIRS) is a noninvasive technique widely used in neonatal pain research to measure functional activation of the cortex.20, 21, 22, 23 NIRS has revealed that blood sampling can activate the neonatal somatosensory20, 21, motor24, and prefrontal22 areas starting at the 25th week of postmenstrual age. Pain increases oxygen consumption with changes occurring in the primary somatosensory cortex on the brain surface.25, 26 Additionally, the relationship between the total Premature Infant Pain Profile (PIPP)27 score and hemodynamic response has been evaluated.
Among the analgesics studied for neonatal pain, breast milk is a natural substance beneficial and nutritious for infants.32 Whether breast milk administration alters cortical brain activation in neonates is presently unclear. Therefore, we conducted a trial to assess whether breast milk can relieve cortical pain during a painful metabolic disease screening procedure.

Outcome Measures
Primary Outcome Measures
- The rScO2 measure was the primary outcome. [2 months]
A near-infrared spectroscopy device was used to monitor regional cerebral oxygen saturation (rScO2). Pain increases oxygen consumption with changes occurring in the rScO2 measure.
Secondary Outcome Measures
- The Neonatal Pain, Agitation, and Sedation scale [2 months]
The mean of the Neonatal Pain, Agitation, and Sedation score (A score >+3 indicates pain)

Exclusion Criteria:
- Neonates born before 37 weeks of gestation
