Sleep Apneas and Acid Esophageal Reflux in Control Infants and in Infants with an Apparent Life-Threatening Event

摘要: Clinical experience shows that episodes of apnea can occur during regurgitations or vomiting. We questioned whether sleep apneas could be related temporally to documented falls in esophageal pH, when no clinical symptoms emesis are witnessed. Twenty infants admitted after an apparently life-threatening event (‘ALTE’) sleep, but with vomiting at the time event, and ten control were studied. All had occasional regurgitations. Polygraphic monitoring state alertness, cardiorespiratory activity low pH was performed continuously 1 night. The data analyzed blindly. A total 334 central 36 obstructive monitored, mainly ALTE group, NREM sleep. 116 below 4 units seen 18 infants; 50% occurred wakefulness, 31 % REM Arousals body movements preceded fall cases. Within 5 min following reflux onset, (7.2% apneas) seen. There correlation between duration, lowest values measured, number duration apneas. No apnea, bradycardia arousal followed pH. Acid did not play a significant role development our population.
