Clinical Trial Summary

The goal of this clinical trial is to evaluate the effects of minimal enteral nutrition (MEN) on mesenteric blood flow and oxygenation with Doppler USG and Near Infrared Spectroscopy (NIRS) during therapeutic hypo¬thermia (TH) in babies with hypoxic ischemic encephalopathy. The main question it aims to answer is: 1- How do the mesenteric blood flow and oxygenation get affected with MEN during TH? Participants will be either fed with MEN during TH or given placebo.

Description:

Objectives: The investigators aimed to evaluate the effects of minimal enteral nutrition (MEN) on mesenteric blood flow and oxygenation with Doppler USG and Near Infrared Spectroscopy (NIRS) during therapeutic hypo¬thermia (TH) in babies with HIE. Methods: This prospective, randomized controlled study was conducted between September 2020 to August 2022. The infants receiving MEN during hypothermia (n =30) and those who were not fed (n=30) constituted the study and control groups. Infants were monitored continuously with NIRS and mesenteric arterial blood flow velocities were measured with Doppler USG before and after feeding.

Eligibility

Inclusion Criteria:

• The neonates with evidence of encephalopathy de¬fined by seizures or abnormalities on a modified Sarnat exam were enrolled. The hypoxic-ischemic injury was defined by 1. a pH of = 7.0 and/or 2. base deficit >-16 mmol/L recorded in cord blood or blood gas obtained within the first hour postnatally or a pH of 7.0 - 7.15 and/or base deficit (-10-15.9) mmol/L with the presence of an acute perinatal event (cord prolapse, placental abruption, heart rate decelerations, severe fetal bradycardia). In cases where criteria 1 or 2 are met, with the presence of seizures or a diagnosis of moderate to severe encephalopathy according to the Sarnat & Sarnat classification based on neurological examination were treated with TH.

Exclusion Criteria:

• Infants with congenital malformation or hereditary metabolic diseases, infants whose enteral feeding was initiated before randomization and infants without lack of parental consent were excluded. The maternal and neonatal demographic characteristics and clinical outcomes were collected from medical records.

Intervention

Dietary Supplement:
• Minimal enteral nutrition
The babies were randomized into two groups based on whether they received MEN during TH. While the babies fed with MEN during TH constituted the study group, the control group was composed of the babies who were given the same amount of distilled water according to the same protocol. Two groups were compared in terms of demographic characteristics, clinical outcomes, NIRS and Doppler measurements.
