Objective: To explore distribution and correlative factors of desaturation events in the neonates admitted into hospital.

Method: TcSO2 of 73 neonates admitted into hospital, male 48 and female 25, with postnatal age ranged between 30min to 28 days, were recorded with polysomnography, and distribution of the mean SaO2, minimum SaO2, frequency, and duration of the desaturation events, and the correlation between these parameters and different vital indices, such as gestational age (GA), postconceptional age (PCA), days of age, and body weight, were analyzed, respectively.

Results: Mean SaO2 of the desaturation events were 96%(84%, 99%), minimum SaO2 76.3%7.6%, frequency 23.9(2.6, 95.2) spells/h, and duration 10(5, 46)s. Their difference among groups of different disease, and between groups of different gender, were not significant statistically (P>0.05).Postnatal days of the neonates were correlated with frequency of desaturation events positively(rs’=0.28, P<0.05), and with duration inversely(rs’=-0.25,P<0.05).The correlative coefficients between Apnea/ Hypopnea Index(AHI) and GA was –0.18 (P<0.01), and between AHI and PCA,-0.17(P<0.01).

Conclusions: No significant difference were found for the difference of desaturation events parameters among different diseases or between different gender. Postnatal days were an index that correlated with frequency positively, and with duration inversely, of desaturation events, and AHI was correlated inversely with GA and PCA, respectively.
