Abstract 1300

Bronchopulmonary dysplasia (BPD) but not intraventricular hemorrhage (IVH), common complications of prematurity influenced the pneumocardiogram (PCG) obtained at hospital discharge. The BPD group, composed of 29 infants (971.6+/-284.4g; 27.3+/-1.3wks) were significantly lighter and less mature that the 151 controls (2058+/-843g; 33.2+/-3.9wks p<.001) and were older at the time of study (postconceptional age: 38.0+/-1.3wks vs. 36.0+/-3.0wks), reflecting a longer length of stay. PCG's consisting of a combination of heart rate, respiratory rate, nasal air flow, and pulse oximetry were done on infants requiring home monitoring. There were statistically significant (p<0.01) differences identified in the incidence of prolonged apnea (69.0 vs. 41.1%), central apnea (65.5 vs. 32.5%), obstructive apnea (34.4 vs. 58.3%), mixed apnea (20.7 vs. 68.9%), and excessive periodic breathing (4.8 vs. 55.6%).
