15-year audit of post-tonsillectomy haemorrhage at Dunedin Hospital.
Post-tonsillectomy haemorrhage is a significant complication because of its frequency and consequences. Increases in post-tonsillectomy haemorrhage prevalence have been reported. There is a controversy about whether increasing the use of diathermy techniques or anti-platelet aggregation effects of analgesia could have caused this increase. We carried out an audit of post-tonsillectomy haemorrhage and examined the rates of readmission for bleeding during the period 1990-2004. We also recorded the surgical technique used and the use of perioperative non-steroidal anti-inflammatory drugs and corticosteroids. During this period there has been a significant increase in post-tonsillectomy haemorrhage with an average annual increase of 15.3% (P<0.0001, 95% confidence interval 8.5-22.5%). The increase is coincidental with the change-over to predominant diathermy technique and a routine use of postoperative non-steroidal anti-inflammatory drugs and steroids.
