title: Oxidised cellulose powder for haemostasis following sinus surgery: a pilot randomised trial.
abstract: BACKGROUND
  Haemorrhage is the most common major complication of endoscopic sinus surgery. Post-operative absorbable or non-absorbable nasal packing can cause pain and blockage. Haemostatic powders or gels may prevent this problem. However, when based on factors in the clotting cascade, they induce an inflammatory reaction and can cause post-operative synechiae. Oxidised cellulose powder produces haemostasis without inducing synechiae formation, but has not been trialled for sinus surgery.
  
  
  METHODS
  A randomised clinical trial was performed to compare cellulose powder to non-absorbable packing following sinus surgery. Participants were 50 consecutive patients undergoing sinus surgery, 47 of whom completed the study. The main outcome measures were post-operative bleeding, pain scores and synechiae formation.
  
  
  RESULTS
  Cellulose powder was effective at stopping bleeding, and was associated with less pain than nasal packing, with no evidence of increased synechiae formation.
  
  
  CONCLUSIONS
  Cellulose powder appears to be a good haemostatic agent following sinus surgery. A larger trial would allow more accurate quantification of its effectiveness.
