Objective: To explore the necessity of monitoring polysomnography (PSG) in snoring children.
Method: The PSG were monitored in 162 children with snoring or apnea. According to results of PSG, 162 cases were separated into two groups:group obstructive sleep apnea hypopnea syndrome(OSAHS) and group primary snoring (PS), monitoring data including:apnea hypopnea index (AHI), snoring index(SI), lowest oxygen saturation (LSaO2) and time of SaO2 < 0.9, all data were undertaken statistical analysis.
Result: In all 162 snoring cases,150 cases (92.6%) belong to group OSAHS, 12 cases (7.4%) belong to group PS; Differences of data of age, sex and body mass index (BMI) are not significant but that of AHI, SI, LSaO2 and time of SaO2 < 0.9 are significant (P < 0.05).
Conclusion: It's necessary to monitor PSG in snoring children for early diagnosis and correct treatment to a void disadvantage of OSAHS.
