title: [Postoperative application of nasopharyngeal airway in rhinogenous obstructive sleep apnea hypopnea syndrome patients].
abstract: OBJECTIVE
  To investigate the postoperative application of nasopharyngeal airway (NPA) in rhinogenous obstructive sleep apnea hypopnea syndrome (OSAHS) patients, so that to observe the parameters including vital signs of the patients and evaluatethe value of clinical application and reliability of NPA.
  
  
  METHODS
  A total of 216 patients diagnosed as rhinogenous OSAHS were randomly assigned to experimental group (setting NPA, 112 cases) and control group (not setting NPA, 104 cases) according to whether NPA was placed in the nasal cavity postoperatively. ECG, oxygen saturation and hemodynamics were monitored for 24 h postoperatively. The pharyngeal pain and discomfort, low oxygen saturation and hemodynamics were compared between these two groups. The subjective assessment and clinical symptoms were compared between the two groups using visual analogue scale (VAS).
  
  
  RESULTS
  The experimental group showed better relief of nasal obstruction, nasal pain, headache, dry pharynx, insomnia and pain while taking out nasal packing compared with control group, where the differences were statistically significant (P < 0.01). In the experimental group, the level of LSa2O2 (P < 0.05), HR (P < 0.01), SBP (P < 0.05), DBP (P < 0.01), MAP (P < 0.01) and RPP (P < 0.01) was significantly lower than in the control group.
  
  
  CONCLUSIONS
  The postoperative application of nasopharyngeal airway in rhinogenous OSAHS patients could help to keep nasal patency and avoid the upper airway obstruction, which exhibited good safety and compliance. The nasopharyngeal airway can reduce patients' discomfort and improve hyoxemia, ensuring hemodynamic stability.
