title: [Analysis of bleeding cause after uvulopalatopharyngoplasty with endotherm knife].
abstract: OBJECTIVE
  To summary and analyze the bleeding causes after uvulopalatopharyngoplasty(UPPP) with endotherm knife, and preventive measures will be given to effectively reduce postoperation hemorrhage.
  
  
  METHODS
  Two hundred and twenty-six cases of obstructive sleep apnea hypopnea syndrome (OSAHS) adult patients, were carryed out UPPP under general anesthesia with endotherm knife to observe postoperation hemorrhage.
  
  
  RESULTS
  Eight cases out of 226 patients or 3.5% occurred postoperation hemorrhage, 2 cases after 1 or 2 days, 6 cases after 6 or 12 days. The postoperation hemorrhage stopped by local compression hemostasis or bi-polar coagulation hemostasis, and no more bleeding occurred.
  
  
  CONCLUSIONS
  The minimal trauma, quick operation and less-bleeding will be caused by UPPP with endotherm knife. Few patients 3.5% had a small amount of bleeding after operation, but no serious bleeding occured. Hemorrhage often happened during pseud mucosa falling off period. The bleeding was related with using skill of endotherm knife during operation, postoperation pse-ud mucosa falling off, local inflammation, improper eating and emotional stress of patients.
