About

This clinical trial aims to learn if enteral feeding influences cerebral and splanchnic oxygenation during red blood cell infusion in very low birth-weight preterm infants. It will also learn about how continuing or withholding enteral feeding during blood transfusion might trigger transfusion-related necrotizing enterocolitis. The main questions, it aims to answer are:

• Does continuing or withholding enteral feeding have any impact on splanchnic and cerebral oxygenation in very-low-birth-weight preterm infants?
• Does continuing enteral feeding result in feeding intolerance during red blood cell infusion or transfusion-related necrotizing enterocolitis (TANEC) in very-low-birth-weight preterm infants? Researchers will compare regional cerebral and splanchnic oxygenation obtained by Near Infra-Red Spectroscopy (NIRS) monitoring while receiving red blood cell transfusion.

Participants will:

• Continue or withhold enteral feeding during red blood cell infusion, and all participants will be under NIRS monitoring for the following 48 hours after the blood transfusion.
• Be monitored for any signs and symptoms of new-onset feeding intolerance and/or necrotizing enterocolitis for 48 hours following the blood transfusion

Full description

Continuing enteral feeding during red blood cell transfusion can have a negative impact on cerebral and splanchnic oxygenation and trigger transfusion-related necrotizing enterocolitis (TANEC) in very low birth-weight infants of gestational age less than 32 weeks and/or birthweight less than 1500 grams. However, the issue of continuing or withholding enteral feeding to prevent TANEC in these neonates is a matter of debate. Enteral feeding is often withheld during blood transfusion to prevent TANEC.

This study was carried out to investigate the effect of enteral feeding during red blood cell infusion on cerebral and splanchnic oxygenation in low-birth-weight preterm infants. Secondary hypothesis was to observe (if any) the signs and symptoms of a new-onset feeding intolerance and/or necrotizing enterocolitis for 48 hours following the blood transfusion.

Enteral feeding will continue or be withhold in very low birthweight neonates during packed red blood cell transfusion. Regional cerebral and splanchnic oxygenation were measured using near-infrared spectroscopy (NIRS) for 48 hours.

45 participants in 2 patient groups

Feeding continued arm

Active Comparator group

Description:

Enteral feeding will continue during packed red blood cell transfusion. Regional cerebral and splanchnic oxygenation will be measured using near-infrared spectroscopy (NIRS) for 48 hours. Cerebral and splanchnic oxygenation parameters, including cerebral regional oxygen saturation (crSO2), splanchnic regional oxygen saturation (srSO2), the ratio of crSO2 to srSO2 (CSOR), cerebral fractionated tissue oxygen saturation (cFTOE) and splanchnic fractionated tissue oxygen saturation (sFTOE) will be measured immediately before PRBCT (baseline) and at the first, sixth, 12th, 24th, and 48th hours after PRBCT using near-infrared spectroscopy.

Treatment:

Dietary Supplement: Enteral feeding

Feeding restricted arm

Active Comparator group

Description:

Enteral feeding will be withhold during packed red blood cell transfusion. Regional cerebral and splanchnic oxygenation will be measured using near-infrared spectroscopy (NIRS) for 48 hours. Cerebral and splanchnic oxygenation parameters, including cerebral regional oxygen saturation (crSO2), splanchnic regional oxygen saturation (srSO2), the ratio of crSO2 to srSO2 (CSOR), cerebral fractionated tissue oxygen saturation (cFTOE) and splanchnic fractionated tissue oxygen saturation (sFTOE) will be measured immediately before PRBCT (baseline) and at the first, sixth, 12th, 24th, and 48th hours after PRBCT using near-infrared spectroscopy.
