The purpose of this study is to evaluate the role of endotracheal suction on the occurrence of meconium aspiration syndrome in depressed meconium stained babies. Meconium aspiration syndrome (MAS) is believed to result from aspiration of meconium and consequent chemical pneumonitis. Meconium can be aspirated into the lungs in the womb as well. Meconium in the distal airways is not accessible to endotracheal (ET) suction which clears only the windpipe. Furthermore there is growing evidence in support of asphyxia-hypoxia-acidosis in the causation of lung disease. Moreover, in the absence of a clear role of ET suction in depressed meconium stained newborns, critical time could be lost in assessment, intubation and ET suction (range: 30 seconds to 1 min) which might delay the definitive step of ventilation for resuscitation of such babies that can potentially affect the outcome adversely.The utility or futility of endotracheal suction in preventing MAS in depressed meconium stained neonates has not been systematically studied and there is inadequate information in literature in favor or against this practice.Thus this study is an attempt to evaluate the effect of endotracheal suction on the occurrence of MAS in depressed full term neonates born through meconium stained amniotic fluid (MSAF).
