English Abstract

To evaluate whether the system-based strategy for management of meconium aspiration syndrome (MAS) could reduce the morbidity and mortality rate of MAS in our institute, a prospective consecutive clinical observation was conducted. System-based strategy including appropriately trained the relevant medical staff to familiar with neonatal resuscitation program, early surfactant replacement or lavage following with high-frequency ventilator (HFV) and/or inhaled nitric oxide (iNO). Outcome measurements were the morbidity and mortality rates of MAS. All infants of MAS in the study period were included except cases of congenital malformations or cyanotic congenital heart disease (CHD). Oxygen, nasal continuous positive airway pressure (CPAP), and intermittent mandatory ventilation (IMV) were applied as clinically indicated. Surfactant was used as replacement or lavage therapy for MAS infants whose oxygen index (OI) exceeded 20 or value for AaDO2 exceeded 400 within 6 hours of age. High-frequency oscillator ventilation (HFO) was applied for infants of MAS that demonstrated intractable respiratory failure with conventional mechanical ventilation and 100% oxygen. Inhaled nitric oxide (iNO) was used with IMV or HFO for infants of persistent pulmonary hypertension (PPHN) when it was unresponsive to conventional therapy. Dexamethasone was prescribed in infants of severe hypotension that did not respond to dopamine and epinephrine. A series of 198 consecutive infants of MAS born in this hospital during 9 years were analyzed. There was no mortality. Fourteen infants developed PPHN, 11 had pneumothorax, 1 had pulmonary hemorrhage, 2 had neurologic sequelae because of severe asphyxia, and 2 developed bronchopulmonary dysplasia. Our results indicated that appropriately trained relevant medical staff with neonatal resuscitation program to avoid complicated MAS and early surfactant replacement or lavage following with HFO and/or iNO could reduce the morbidity and mortality rate of MAS even without extracorporeal membrane oxygenation (ECMO).
