Study Progress Of Pediatric Obstructive Sleep Apnea Hypopnea Syndronme

Objective:To discuss epidemiological characteristics of pedia- tric OSAHS within area；OSAHS diagnosis and its impact on chil- dren's growth were considered for the purpose of living quality imp- rovement.Methods:1092 children from three primary school of FAW community include pre-school classes and Grade one and two classes received epidemiologic examination,if obstructive sleep apnea synd- rome(OSAS) was identified,pharyngeal check-up,fibrous endo- scopic,lateral x-ray,acoustic impedance or sleep oxygen saturation studies.This study,on the basis of Beijing TongRen draft enacted in HangZhou OSAHS special topic conference hold in April,2002,Combining abroad articles,give the definition of hypopnea as sleep time of airflow less than 50% of fundamental level≥6s,hypopnea with oxygen saturation decrease≥4%,give the definition of apnea as stopping time of mouth and nose airflow≥6s.In total,diagnosis stan- dard of children OSAHS is apnea hypopnea index(AHI)≥5time/h, and lowest oxygen saturation(LSaO2)<92%.After results turned out,statistics analysis including t-test and x2-test was carried on.Result:During epidemiological study on 1092 children,female and male children are 535 and 557 respectively.The average age is between six and seven prevalence of snoring without apnea is 20%,Snoring and apnea is 8%,clinically diagnosis OSAHS is 2%.No statistic meaning appeared in group rate of disease and sex difference.Compare snoring without apnea group with Snoring with apnea group has lower body height but no apparent difference on body weight.As to sleep position 19 children with OSAHS have face-to-ground position,38 children with snoring and apnea have lateral position and 34 children have face-to-ground position.on other hand 498 children with no snoring lies supine.All OSAHS children cases were once infected tonsillitis and(or)rhinitis.Among snoring and apnea group,86 cases were found to have tonsillitis and(or)rhinitis.OSAHS group and group with snoring and apnea lave such complication as attention,multiple motion,descending learning scores poor memory as well as day sleep. With the comparison of OSAHS without snoring.Comparison OSA- HS group and snoring and apnea group with without snoring group has dramatically higher complication incidence.This study make nig- ht oxygen saturation on 87 volunteers with snoring and apnea during sleep,23 with LSaO2<92%,were clinically diagnosed OSAHS.Also saturation impair time below 90%(SIT90%)were observed to time duration has big influence on clinical symptom.Conclusion:1.Incid- ences of snoring is 20%,snoring with apnea is 8%,23 children(2% incidences)were diagnosed OSAHS. All these prevalence are higher than abroad report,but no great divergence on intergroup prevalence and sex aspects.2.OSAHS group with snoring and apnea were dem- onstrated to have lower body height than group without snoring. Where no body weight difference between the two groups. 3. Most children with OSAHS are accustomed to face-to-ground sleep posi- tion to maintain upper airflow opening.4.OSAHS group with snoring and apnea have higher prevalence of tonsillitis and(or) rhinitis compared with group without snoring.Therefore this conclusion reck- on recurrent tonsillitis and(or)rhinitis are the major cause of OSAHS. 5.OSAHS group with snoring and apnea has higher prevalence of co- mplication than group without snoring.Indicating OSAHS have sev- ere damage on children growth and quality improvement.6.This study apply simple oxygen saturation instrument,Which can is painless and lower charged.In addition, overnight oxygen saturation is monitored and lowest oxygen saturation and its time may be set. All these advantage play important role on diagnosis of children OSAHS. OSAHS as an important field is worth observation.
