Mesenteric tissue oxygenation status on the development of necrotizing enterocolitis

Area of Science:

• Neonatalogy
• Gastroenterology
• Medical Devices

Background:

• Necrotizing enterocolitis (NEC) is a significant cause of illness and death in preterm infants.
• Limited data exists on mesenteric oxygenation during initial enteral feeding.
• This study investigates mesenteric oxygen saturation and its impact on NEC development.

Purpose of the Study:

• To measure mesenteric tissue oxygen saturation before, during, and after the first enteral feeding in preterm infants.
• To assess the relationship between mesenteric oxygenation levels and NEC development.
• To explore the potential of mesenteric oxygenation monitoring as a predictive tool for NEC.

Main Methods:

• Prospective study including 105 preterm infants (≤ 32 weeks gestational age).
• Continuous mesenteric tissue oxygenation monitoring using near-infrared spectroscopy (NIRS).
• Measurements taken before, during, and 3 hours post-first enteral feeding.

Main Results:

• 11.4% of infants developed NEC (Stages II and III).
• Infants who developed NEC had significantly lower mesenteric tissue oxygen saturation before and 1 hour after feeding.
• Mean saturation levels differed notably between NEC and non-NEC groups.

Conclusions:

• Reduced mesenteric oxygenation before and after initial enteral feeding is associated with NEC.
• Continuous monitoring of mesenteric oxygen saturation may aid in predicting NEC development.
• This monitoring could offer a valuable tool for early NEC risk assessment in preterm neonates.
