• Ventilator adapters that permit endotracheal suction without disconnection from mechanical ventilation may overcome several of the theoretical contributors to the hypoxia and bradycardia associated with neonatal endotracheal suction. Such an adapter allows for partially ventilated endotracheal suction (PVETS) as opposed to traditional, nonventilated endotracheal suction. To test the clinical value of PVETS using an endhole adapter, changes in transcutaneous partial pressure of oxygen and heart rate were compared during paired PVETS and nonventilated endotracheal suction events on 32 occasions in 11 premature neonates with respiratory distress syndrome. Partially ventilated endotracheal suction was associated with a significant decrease in the incidence and severity of hypoxic events. Partially ventilated endotracheal suction, however, did not affect the incidence of bradycardic events; PVETS had a small but statistically significant effect on reducing the severity of bradycardia. No clear relationship between bradycardic and hypoxic events was evident.
