Meconium aspiration is believed to cause persistent pulmonary hypertension syndrome of the newborn (PPHN) via vasoconstriction, whereas meconium has a relaxant effect on rat tracheal muscle. We evaluated the meconium effect on lung vascular and airway mu
Related to meconium aspiration:meconium staining me·co·ni·um (mĭ-kō′nē-əm) n. A dark green fecal material that accumulates in the fetal intestines and is discharged at or near the time of birth. [Latinmēcōnium,poppy juice, from Greekmēkōnion, frommēkōn,poppy.] ...
Ischemia of the gut results in hyperperistalsis and relaxation of anal sphincter that results passage of meconium. As long as the fetus dose not become acidetic, aspiration does not occur. However, if there is more severe hypoxia, gasping in utero will lead to aspiration of meconium. If ...
results in increased water absorption and inspissation of the meconium. Meconium in theamniotic fluidmay indicateintrauterine asphyxia. Aspiration of meconium may have serious effects onpulmonary function, leading to pneumonia,pneumothorax, andpersistent pulmonary hypertension(persistent fetal circulation).110,...
in utero is perinatal aspiration of stained amniotic fluid (before, during, or immediately after birth)—ie, meconium aspiration syndrome (MAS). Aspiration of meconium-stained amniotic fluid may occur if the fetus is in distress, leading to a gasping breathing pattern. This aspiration induces ...
Meconium aspiration syndrome (MAS) is a common neonatal problem and, sadly, results in acute and chronic respiratory morbidity. Although meconium aspiration can occur prior to delivery even in the absence of labour, in many infants this condition could be prevented by appropriate suctioning at birth...
Does meconium cause meconium aspiration syndrome (MAS) or is meconium discharge only a marker of fetal hypoxia? This dispute has lasted for centuries, but since the 1960s, detrimental effects of meconium itself on the lungs have been demonstrated in animal experiments. In clinical MAS, persistent...
2.The main pathologies are meconium aspiration pneumonia, emphysema and the visceras congesting. 主要病理改变为胎粪吸入性肺炎, 肺气肿以及各脏器出血. 3.She doesn’t find the reports of bacteria in meconium all that convincing, however. 4.Aspiration of meconium with the first breath can result in...
Meconium aspiration syndrome (MAS) is a complex respiratory disease that continues to be associated with significant morbidities and mortality. The pathophysiological mechanisms of MAS include airway obstruction, local and systemic inflammation, surfacta
