| Abstract: | Introduction: Apneic episodes in preterm infants can lead to neurological impairment. Current respiratory monitoring uses chest impedance (CI), but apnea detection and classification by CI can be inaccurate. Diaphragmatic electromyography (dEMG) may improve this. We aimed to get insights into the dEMG around hypoxic events in preterm infants. Methods: dEMG was measured for 24 hours in thirteen infants (post-menstrual age 29.2 ± 2.0 weeks). Diaphragm activity was characterized in five periods: 1-5 minutes before, 0-1 minute before, during, 0-1 minute after, and 1-5 minutes after a hypoxic episode. Statistical analyses were performed to test for differences over time for dEMGmax and dEMGmin per second and between central and obstructive apnea. Results: Before a desaturation, dEMGmax and dEMGmin decrease and increase significantly (p < 0.001) in central and obstructive apnea, respectively. Analysis of mixed apnea showed stable dEMG. However, central and obstructive components are discernible in single events. 953 hypoxic events were scored, of which, after removing 167 noisy events, 9% were classified as central, 41% as obstructive, and 51% as mixed. Conclusion: dEMG is a technique that can detect apnea events before alarming desaturation occurs. The electrical activity of the diaphragm is ahead of the SpO2 and HR. |
