title: [Observation the clinical curative effect of children's laryngopharyngeal reflux and sleep apnea hypopnea syndrome].
abstract: OBJECTIVE
  To observe the clinical curative effect of anti-reflux treatment for obstructive sleep apnea hypopnea syndrome (OSAHS) in children.
  
  
  METHODS
  Twenty children with sleep-disordered breathing were included in this study. There were 15 males and 5 females, aged 3-9 years old, median 6 years old. The electronic laryngoscope, polysomnography (PSG) monitoring, Reflux symptom index (RSI) questionnaire and Reflux finding score (RFS) were used to establish the initial diagnosis of OSAHS with LPRD, preclude adenoid hypertrophy and tonsil hypertrophy and nasal disorders. Oral Domperidone and Omeprazole were given for treatment. For children under 3-year-old, the dosage of Domperidone was 0.6 ml.kg⁻¹.day⁻¹.For children over 3-year-old, Domperidone combined with Omeprazole were given with the dosage of 0.3 mg.kg⁻¹.day⁻¹.
  
  
  RESULTS
  After 4 weeks of treatment, 19 patients symptoms of OSAHS include disturbed sleep, dyspnoea and apneic attack improved. After 8 weeks of treatment, 20 cases with OSAHS symptoms improved than before treatment. Under the electronic laryngoscope, the decrease in pharyngeal lymphoid follicles, the epiglottis, aryepiglottic fold and scoop intergenic region erythema shallow, edema lessened. After treatment of 4 weeks and 8 weeks, there was statistically significant (P < 0.05). Before and after treatment, the difference of RFS was statistically significant (P < 0.05); PSG monitoring proved significant effect in 3 cases (15.0%), effective in 11 cases (55.0%) and 6 cases were ineffective (30.0%). Twenty patients with obstructive apnea index change was not obvious (P > 0.05), apnea hypopnea index and lowest artery oxygen saturation better, differences were statistically significant (Z of 2.819 and 2.733 respectively, P < 0.05).
  
  
  CONCLUSIONS
  The treatment of LPRD can improve the symptoms of OSAHS, these two diseases may coexist in mutual relations.
