title: [Clinical observation on obstructive sleep apnea-hypopnea syndrome cases in snoring children].
abstract: OBJECTIVE
  To explore the necessity of monitoring polysomnography (PSG) in snoring children.
  
  
  METHODS
  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.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  It's necessary to monitor PSG in snoring children for early diagnosis and correct treatment to a void disadvantage of OSAHS.
