Pathophysiology Of Meconium Aspiration Syndrome

Meconium is the first intestinal discharge from newborns. MAS can present with varying degrees of severity from mild respiratory distress to life-threatening respiratory failure. Aspiration can occur in utero with fetal gasping or after birth with the first breaths of life. Findings include tachypnea rales and rhonchi and cyanosis or desaturation. Findings include tachypnea rales and rhonchi and cyanosis or desaturation. Meconium Aspiration Syndrome MAS is the term used to describe a spectrum of disorders marked by various degrees of respiratory distress in the new born infant. This paper describes the pathophysiology of MAS.

Intrapartum meconium aspiration can cause inflammatory pneumonitis and mechanical bronchial obstruction causing a syndrome of respiratory distress.

Meconium aspiration syndrome MAS is a result of ante- or postpartum aspiration of meconium-stained amniotic fluid in term or near-term infants resulting in respiratory morbidity of varying severity. Perinatal hypoxia acute airway obstruction pulmonary inflammation pulmonary vasoconstriction pulmonary hypertension and surfactant inactivation all play a role in the pathogenesis of meconium aspiration syndrome MAS. Meconium aspiration syndrome MAS is a result of ante- or postpartum aspiration of meconium-stained amniotic fluid in term or near-term infants resulting in respiratory morbidity of varying severity. This follows the aspiration of meconium stained amniotic fluid MSAF which can happen either antenatally 28 of all pregnancies or during birth up to 23 of all pregnancies 1.

1 Despite rapid advances in diagnostic and therapeutic modalities over the past decades meconium and its effects on fetus and neonates have remained a cause of significant worry for. Meconium Aspiration Syndrome MAS is the term used to describe a spectrum of disorders marked by various degrees of respiratory distress in the new born infant. Severe MAS is classified as cases that need mechanical ventilation.

This paper describes the pathophysiology of MAS. This follows the aspiration of meconium stained amniotic fluid MSAF which can happen either antenatally 28 of all pregnancies or during birth up to 23 of all pregnancies 1. However considering that meconium is stored in the intestines partly unexposed to the immune system aspirated meconium could be recognized as danger representing damaged self.

It describes the spectrum of disorders and pathophysiology of newborns born in meconium-stained amniotic fluid MSAF and have meconium within their lungs. Though meconium is released prematurely by about 20 of fetuses or babies approximately 5 of babies that are born with the presence of meconium in the uterine amniotic fluid develop Meconium Aspiration Syndrome MAS. The meconium aspiration syndrome MAS is often preventable yet cases of MAS continue to occur.

Meconium aspiration syndrome MAS also known as neonatal aspiration of meconium is a medical condition affecting newborn infants. O MAS is distinct from aspiration of other substances such as blood and amniotic fluid which may produce similar respiratory symptoms Pathophysiology 1. Findings include tachypnea rales and rhonchi and cyanosis or desaturation.

Perinatal hypoxia acute airway obstruction pulmonary inflammation pulmonary vasoconstriction pulmonary hypertension and surfactant inactivation all play a role in the pathogenesis of meconium aspiration syndrome MAS. Meconium aspiration syndrome MAS is defined as respiratory distress in newborn infants born through meconium-stained amniotic fluid MSAF whose symptoms cannot be otherwise explained 1.
