Brief Summary:

Although the pathophysiology of meconium obstruction of prematurity (MOP) is not clear, it is known that the decrease of the intestinal peristalsis due to decreased intestinal perfusion during antenatal or perinatal period. Recently, the level of citrulline has been used as an index of function and injury of the small intestine State. This study aimed to evaluate citrulline level of cord blood as a marker for early detection and observe changes in intestinal blood flow in MOP patient.

And We aimed to confirm the efficacy of the AT/ET ratio (ratio of the pulmonary artery time-to-peak velocity interval to the right ventricular ejection time) of the prenatal pulmonary artery as a noninvasive predictor of neonatal respiratory distress syndrome.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Comparison of citrulline level between the meconium obstruction group and the normal feeding advance group [ Time Frame: within 6 hours after birth ]
    check the citrulline llevel from blood at birth

  2. Comparison of prenatal AT/ET ratio of fetal pulmonary artery between respiratory distress syndrome group and the normal respiration group [ Time Frame: within 10 days before delivery ]
    Check the AT/ET ratio of fetal pulmonary artery within 10 days before birth


Biospecimen Retention:   Samples Without DNA
Blood sample at birth for citrulline level analysis urine sample at the first day of life for fatty acid binding protein analysis
