Abstract
Otherwise healthy preterm infants may continue to exhibit prolonged apnea beyond the first week of life, a condition some consider leading to an increased risk for SIDS. To elucidate the significance of these apnea, we studied 17 AGA infants between 32-36 weeks post conceptual age. Eight of these (A) exhibited 2 or more central apnea ≥20 sec. during an 8 hour period after the first week of life.
Polygraphic records were obtained between 6-10 pm at 40 weeks, 1 month and 3 months adjusted age, from which Quiet Sleep (QS) and Active Sleep (AS) were derived. Minute by minute values for heart rate (HR), respiratory rate (RR), transcutaneous O2 (PtcO2) and CO2 (PtcCO2) were determined during AS and QS with a computer. Representative results at 40 wks are presented as mean and (sd).
Apneic preterms were not different from non-apneic infants (N) at this either of the other follow up ages. While preterm infants are statistically at increased risk for SIDS, these data do not warrant singling out the apneic prcterm as at greater risk for abnormal autonomic sequelae.
