Management of Extubation Issues in Preterm Neonates

Initial Respiratory Support Approach

For spontaneously breathing preterm infants at 25 weeks' gestation with respiratory distress, either CPAP or intubation with mechanical ventilation can be used, with the choice guided by local expertise and preferences, as recommended by the American Academy of Pediatrics 1, 3
CPAP compared with intubation in infants at 25-28 weeks' gestation has been shown to reduce rates of mechanical ventilation from 100% to 46% and surfactant use from 77% to 38%, although with a slightly increased risk of pneumothorax (9% versus 3%), according to the American Academy of Pediatrics 1, 4
When positive-pressure ventilation is required for preterm infants, an initial inflation pressure of 20-25 cm H₂O is adequate for most cases, as suggested by the American Heart Association 5, 6

PEEP is beneficial during initial stabilization of apneic preterm infants requiring positive-pressure ventilation, as recommended by the American Academy of Pediatrics 4, 7
Avoid excessive chest wall movement during ventilation of preterm infants immediately after birth, as advised by the American Academy of Pediatrics 6, 8

Ventilation can be performed effectively with a flow-inflating bag, self-inflating bag, or pressure-limited T-piece resuscitator, according to the American Heart Association 3, 7
T-piece resuscitators deliver target inflation pressures more consistently and maintain PEEP more effectively than self-inflating or flow-inflating bags, as suggested by the American Heart Association 5, 9

High levels of PEEP (8-12 cm H₂O) may reduce pulmonary blood flow and increase the risk of pneumothorax, as warned by the American Heart Association 5, 6
Avoid unnecessarily high pressures during ventilation to prevent lung injury, as recommended by the American Academy of Pediatrics 1, 6
The laryngeal mask airway has not been evaluated in extremely preterm infants and should be used with caution in this population, as advised by the American Heart Association 3, 7
