- Abstract:
- In 24 patients at risk for SIDS (12 infants with a near miss event and 12 infants with apnea and perioral cyanosis during sleep) respiratory and esophageal function were investigated by impedance pneumography (IP) and esophageal manometry combined with simultaneous pH-monitoring (EMPH). Both groups had ad early pathologic breathing pattern, but did not show any difference in the recorded parameters (number of apneic spells, longest apneic spell, apneic spells longer than 10 seconds, transcutaneous oxygen pressure, mean apnea time). Near miss infants had about 50% more manometric refluxes (15.4 +/- 1.3) than the apnea/cyanosis group (9.9 +/- 2.2). This difference was mainly caused by a significant rise of reflux episodes without pH-change (near miss 8.5 +/- 3.1 versus 2.9 +/- 1.4 in apnea/cyanosis infants). Furthermore, propulsive peristaltic properties after induced swallows were more disturbed in the near miss group (3.3 +/- 1.0 versus 6.1 +/- 1.9). On the other hand, the apnea cyanosis group showed significantly more pH-drops under 4 (6.8 +/- 2.3 vs 2.4 +/- 0.7), which might be due to a more rapid clearance of neutralising milk from the stomach in these infants. In conclusion the study showed that infants with a near miss event in the anamnesis suffer from a more pathologic esophageal motor function when compared with infants with apneic spells and cyanosis during sleep. Near miss infants are also considered to have a delay of gastric clearance.
