ABSTRACTBackground: Bronchopulmonary dysplasia (BPD) is associated with frequent events of hypoxemia specially during feeding. Objective: To determine peripheral oxygen saturation (SpO2) among infants with BPD before, during and after feeding. Methods: Patients with diagnosis of BPD were prospectively studied between July-September, 2005. SpO2 was measured with a manual digital pulsioxymeter 5 times during feeding. Alpha levels were set at p‹0.05. Results: 67 events were studied in 18 patients. For each participant, oxygen saturation was measured five times yielding a total of 335 recordings. Frequent desaturation episodes were recorded during feeding, (SpO2‹88%) in 16 of the 18 cases. SpO2 reached ‹80% for some recordings among 67% of participants (n=12), with p‹0.001. Conclusion: Among BDP patients, SpO2 decreases during feeding,reaching severe desaturations (SpO2< 80%) among in two thirds of the cases. Oxygen concentration must be sufficiently increased during feeding in order to rise the level of SpO2 to a minimum of 88%.
