There is an increasing incidence of Necrotizing Enterocolitis (NEC) affecting the premature infant population, principally those with associated risk like extreme prematurity, extreme low birth weight, associated co-morbidities (Congenital heart disease, perinatal asphyxia) and those born in hospitals with limited resources for optimal neonatal care.
Near Infrared Spectroscopy (NIRS), has been used in premature infants to evaluate changes in cerebral perfusion and oxygenation. (1) It provides real time insight into the oxygen delivery.(3) In the premature patient population, many neurologic injuries occur as a result of prenatal (pre-existing) and/or postnatal disturbance on oxygen delivery. NIRS has been focused in cerebral monitoring. Light easily penetrates through neonatal bone and skin tissue, and allows to monitor the subjacent oxygen content. Early studies were performed to validate NIRS measurements and have established normative data.(4-6) The non-invasive method of monitoring cerebral hemodynamics and oxygenation has revolutionized the intensive care units in patients at risk for neurological injuries. This method has been successfully validated to monitor neonatal cerebral oxygenation in different clinical settings and study protocols. (7) NIRS provides non-invasive, continuous information on tissue perfusion and oxygen dynamics.
One of the biggest challenges of NEC spectrum diseases is in the making of early diagnosis. It is important to monitor not just cerebral perfusion but also the intestinal oxygenation.(8,9) Previous studies with NIRS have demonstrated that premature infants change their cerebral - splanchnic oxygenation ratios during feedings.(10) Guy et al. performed NIRS in premature piglets to demonstrate association of perfusion change with NEC spectrum(11,12); these studies suggest evidence that NIRS could be a useful diagnostic tool in the premature infant population trough abdominal NIRS (a-NIRS) measurement capable of detecting alterations in intestinal oxygenation and perfusion.
In summary, a-NIRS could be use in the premature infant population to define reference values, especially in patients at risk, which would then facilitate the early diagnosis of NEC spectrum diseases.

Preterm infants (32 to 36 weeks of postmenstrual age) will be evaluated with a Near infrared Spectroscopy monitor device.
Device: Near Infrared Spectroscopy
NIRS Monitoring with four channels regional areas of the preterm infant, such as: Submandibular, Periumbilical, Abdominal (Spleen region) and infant thigh.
- Abdominal Tissue Oxygenation in Preterm Infant [ Time Frame: 5 days ]Abdominal Tissue Oxygenation will be assessed with the Near Infrared Spectroscopy (NIRS) device, the INVOS 5100c with a time frame of one week in each of the participants, this device will monitor the oxygen tissue status in percentage unit. This outcome measure will be compare during this time frame and the underlying clinical status of the neonate. We then will look for an association between low percentages in the outcome measure and clinical evidences of Necrotizing Enterocolitis.
- Submandibular Tissue Oxygenation in Preterm Infant [ Time Frame: 5 days ]
Submandibular Tissue Oxygenation will be assessed with the INVOS 5100c NIRS device in real time along with the abdominal oxygenation (Primary outcome) and we will follow it principally during feedings.
It is also expressed in percentage.
