GCs reduce the migration of neutrophils into the lungs ergo, decreasing their adherence to the endothelium. Similarly, intestinal parasympathetic innervation and myelination also increases in later gestations. To clear the airways of meconium, tracheal suctioning can be used however, the efficacy of this method is in question and it can cause harm.

This treatment shows promise as it has a significant effect on air leaks, pneumothoraxthe need for ECMO and death. In generally, there is still no generally accepted therapeutic protocol and effective treatment plan for MAS. Persistent pulmonary hypertension PPHN is the failure of the foetal circulation to adapt to extra-uterine conditions after birth.
MECONIUM ASPIRATION SYNDROME
Definition MAS is defined as respiratory distress in a neonate born through meconium-stained amniotic fluid MSAF with characteristic radiological findings hyperinflation and patchy opacities whose symptoms cannot be explained otherwise. Utility of gastric lavage in vigorous neonates delivered with meconium stained liquor: Prevention and management of meconium aspiration syndrome. The management of MAS is primarily supportive with no definite proven therapy.
In such situations, other modalities like inhaled nitric oxide and high-frequency ventilation should be considered early.

Paediatrics and Child Health. Specialty Neonatology Meconium aspiration syndrome MAS also known as neonatal aspiration of meconium is a medical condition aspiragion newborn ppy. The full terms of this license are available at https: By inhibiting COX, and more specifically COX-2either through selective or non-selective drugs inflammation and oedema can be reduced.
Effect of gastric lavage on feeding in neonates born through meconium-stained liquor: Further trials are needed to confirm the treatment effect, define the optimal doses and method of surfactant administration, and compare lavage with bolus administration. Patients with severe mrconium are at risk for respiratory failure, which is often associated with PPHN, right-to-left shunting, and air leaks pneumothorax or pneumomediastinum. Meconium is a source of pro-inflammatory cytokinesincluding tumour necrosis factor TNF and interleukins IL-1IL-6IL-8and mediators produced by neutrophilsmacrophages and epithelial cells that may injure the lung tissue directly or indirectly.
International Journal of Pediatrics.
It provides effective gas exchange at low tidal volume, thus decreasing barotrauma and air leaks. Diagnosis Despite extensive research, the diagnostic criterion for MAS is not well defined.

Then, because of intrauterine gasping or from the first few breaths after delivery, MAS may develop. Erythema toxicum Sclerema neonatorum.
Changing obstetric practices associated with decreasing incidence of meconium aspiration syndrome. Clinical features Neonates with MAS often display the classic signs of postmaturity with peeling of the skin, long fingernails, weight loss, and decreased vernix.

Hypoxia-induced pulmonary arterial vasoconstriction contributes to the development of PPHN which aspirahion a leading cause of mortality in severe MAS. Surfactant enhances the removal of inhaled aspitation and senescent cells away from the alveolar structure.

Cytokine expression in meconium-induced lungs. Surfactant therapy The detrimental effect of meconium on surfactant production and function has been well known and forms the basis of the use of exogenous surfactant in severe MAS.
