Intratracheal catheter suction removes the same volume of meconium with less impact on desaturation compared with meconium aspirator in meconium aspiration syndrome.
Methods
MAS was induced in ventilated rabbits using 3.5 ml/kg of 20% human meconium. Tracheal suction with either catheter suction (CS) or meconium aspirator (MA) was performed after meconium instillation. Percentage of meconium collection rate, PaO2 trends for 2 h after tracheal suction, and acute-phase SpO2 trends were compared between CS and the other three groups, the tube was withdrawn while meconium was aspirated with an MA, then the trachea was reintubated 5, 10 or 15 s after suctioning of meconium.
Results
Percentage of meconium collection rate and PaO2 showed no significant differences between groups. The MA group taking 15 s for reintubation after meconium suctioning, showed a significantly lower acute-phase SpO2 than the CS group (P <>2 to return to ≥ 90% was also longer in the MA group taking 15 s for reintubation than in the CS group (P <>
