Intermittent bag ventilation of preterm infants on continuous positive airway pressure: The effect on transcutaneous
Insights
Intermittent bag ventilation for preterm infants with respiratory distress syndrome can improve oxygen levels (PO2) if the infant remains quiet. Restless infants may experience a decrease in PO2 during this procedure.
Area of Science:
- Neonatal Medicine
- Pediatric Respiratory Care
- Critical Care
Background:
- Preterm infants with respiratory distress syndrome often require respiratory support.
- Continuous positive airway pressure (CPAP) is a common respiratory support method.
- Intermittent bag ventilation is frequently used as an adjunct to CPAP.
Purpose of the Study:
- To assess the impact of intermittent bag ventilation on partial pressure of oxygen (PO2) in preterm infants.
- To determine how infant behavior during bagging influences PO2 levels.
Main Methods:
- Continuous monitoring of transcutaneous oxygen levels (PO2) in preterm infants.
- Observation of infant behavior (restless vs. quiet) during intermittent bag ventilation.
Main Results:
- Infants who were restless during bagging showed a significant decrease in PO2 (P < 0.01).
- Infants who remained quiet during bagging demonstrated a significant increase in PO2 (P < 0.02).
- A sustained PO2 increase (>20 minutes) was observed in nearly half of the infants studied.
Conclusions:
- Infant behavior is a critical factor influencing the effect of intermittent bag ventilation on PO2.
- Intermittent bag ventilation can be beneficial for preterm infants with respiratory distress syndrome, provided they remain quiet during the procedure.
Abstract:
Preterm infants with respiratory distress syndrome requiring continuous positive airway pressure are frequently assisted with intermittent bag ventilation. We assessed the effect of intermittent bag ventilation on PO2 in these infants by continuous monitoring with a transcutaneous oxygen electrode. The behavior of the infants during bagging determined the effect on PO2. Bag ventilation decreased PO2 significantly (P less than 0.01) in infants who were restless during bagging, whereas a significant increase in PO2 (P less than 0.02) was observed in infants who were quiet while being bagged. Although the duration of the increase in PO2 was variable, a sustained rise (greater than 20 minute) occurred in almost half of the infants studied. Intermittent bag ventilation appears to be beneficial in infants who remain quiet during the bagging period.
