The Clinical Study Of Airway Pressure Change After Uvulopalatopharyngoplast Surgery

Objectivel.To evaluate sleep-related obstructive breathing events with obstructive sleep apneahypopnea syndrome,the correlation of ApneaGraph results of esophageal pressure with AHI index, lowest oxygen saturation and Epworth sleepiness score.2.In view of the blocking plane for palatal pharynx ministry of OSAHS patients before and after UPPP surgery ApneaGraph comparing with the results of esophageal pressure analysis, confirmed the effect of UPPP surgery, provide objective basis of AG predict surgical curative effect.3.To use ApneaGraph positioning OSAHS patients with pharyngeal cavity blockage, guide the obstructive sleep apnea hypopnea syndrom scope of operation determine the operation and the role of evaluating the effect of postoperative.MethodWith clinical symptoms and signs and confirmed by clinical examination of OSAHS patients, preoperative routine specialist, ESS questionnaire, awake period on electronic nose pharynx endoscopy and airway CT examination of soft tissue,consider the patient’s blockage is given priority to palatal pharynx level.On preoperative ApneaGraph and Polysomnography,30cases were selected whose blockage is palatal pharynx level to underwent UPPP surgery,the AG and PSG were applied for diagnosis and evaluation of operation effect6month later,to contrast analysis of the observation in patients with esophageal pressure change and the related indicators, and synchronization of the patient’s subjective and objective curative effect.Result1.30cases of patients with obstructive sleep apnea hypopnea syndrom preoperative obstructive apnea and low ventilation biggest average esophageal pressure was positively correlated with AHI, LSaO2, ESS, and negatively correlated with preoperative low blood oxygen, statistically significant.2. compared with the preoperative6months AG indicators,the maximum average esophageal apnea occurs low pressure,the maximum average esophageal pressure ventilation, respiratory events best breathing, breathing hard times, AHI and LSaO2%were improved.3.30cases of patients with curative effect evaluation and preoperative AG the relativity analysis of the indicators, the postoperative down percentage compared with preoperative Pes and AHI and preoperative ropharynx obstrucion percentage between the spearman correlation coefficient is0.721, p<0.001, compared with preoperative Pes and postoperative palatine area up to multiple linear regression analysis after r2=0.514, F=31.731, p<0.01. Preoperative ropharynx obstrucion percentage, the greater the degree of the improvement of postoperative Pes, the more obvious, so the regression equation y=0.854+35.439x, the y for ropharynx obstrucion percentage, x for△Pes%, when x=50%y=78.139%.Conclusion1.there is corelation of the Pes with AHI index, lowest oxygen saturation and ESS score.2.UPPP surgery can improve esophageal pressure, AHI index, lowest oxygen saturation, and patients’quality of life index.3.Combined with morphological examination,ApneaGraph can block parts of the localization diagnosis of OSAHS. Can be used as an evaluation of curative effect of a predictor in the preoperative diagnosis of patients with sleep apnea surgical decision-making, and postoperative effect of objective clinical guidance is of great significance.4.△Pes%as a curative effect evaluation standard, to effectively evaluate the curative effect of patients with OSAHS and participation in the auxiliary curative effect also has important guiding significance to the prediction.
