Background: The significance of meconium in amniotic fluid is a widely debated subject. Traditionally meconium has been viewed as a harbinger of impending or ongoing fetal compromise; however some investigators believe that it is not associated with fetal hypoxia, acidosis or fetal distress. Others have found lower Apgar scores in meconium stained neonates. Objectives: To study the correlation ...

Purpose: This study was undertaken to assess the relationship between the degree of meconium staining of the extraplacental membranes at birth, meconium aspiration, and pulmonary changes in neonates and stillbirth. Methods: The lungs, extraplacental membranes and placenta from 20 stillborn with meconium-stained membranes and 13 lungs of perinatal deaths were collected and microscopically examin...

Perhaps the most significant changes in airway management over the recent years have been in the management of an infant delivered through meconium- stained amniotic fluid( MSAF). MSAF occurs in approximately 10℅ to 20℅ of all deliveries and increases to over 30℅ in deliveries after 42 weeks gestation. Meconium aspiration syndrome ( MAS) occurs in about 2℅ to 5℅ of these cases with a high morta...

Abnormalities in intestinal function associated with changes in meconium, which are usually discussed under the heading of meconium ileus, are responsible for many deaths in the newborn period. Disorders produced by meconium would seem to be largely due to intestinal obstruction due to the meconium being unusually tenacious and firm. The basic constituents of normal meconium have been known for...

OBJECTIVE It is unclear whether children with cystic fibrosis (CF) who present with neonatal meconium ileus have a different long-term outcome from those presenting later in childhood with pulmonary complications or failure to thrive. We examined a cohort of patients with meconium ileus, and compared their long-term outcome with children who had CF without meconium ileus and neonates who had me...

Dear Editor-in-Chief, The inspissated meconium pellets are a cause or effect of ileocolic obstructions. The present study aimed at explaining our experience of ultrasound-based approach for differentiation and treatment of the inspissated meconium pellets. This study was conducted at Mashhad University of Medical Sciences, Mashhad, Iran, from 2017-2020...

Meconium peritonitis results from antenatal perforation of the gastrointestinal tract; it presents as gastrointestinal obstruction, intraabdominal masses, or calcification. The presentation with passage of meconium per vagina secondary to meconium peritonitis is rare. We describe the radiologic and surgical findings in a neonate who had passage of meconium per vagina secondary to ileal atresia ...

This study sought to determine the time interval from fetal defecation to membrane staining and subsequent meconium uptake by amnionic macrophages. Pieces of external membranes were fastened to Teflon rings to create a well. The amnionic surface was exposed to meconium and amniotic fluid for 1 to 48 hours and analyzed microscopically for the presence of free meconium and meconium-laden amnionic...

Introduction: meconium is the thick, Green - Black, with a bad odor material,  that founded around the third month of pregnancy in the intestines of fetus. 8 to 15 percent of infants has the evidence of meconium stained fluid at birth. In this study the factors affecting maternal and neonatal meconium-stained amniotic fluid be examined. Methods: This study was done in the Vali-e- asr hospital ...

We developed a new method for an objective assessment of the meconium content in amniotic fluid. By establishing a standard scale through a serial dilution of a known amount of meconium into the amniotic fluid, we developed a new method "mecometer" that can objectively measure the meconium content in meconium-stained amniotic fluid samples. The objectivity and reliability of this mecometer were...
