title: [Analysis of the causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children].
abstract: OBJECTIVE
  Probe into the causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children.
  
  
  METHODS
  The methods of retrospective analysis the difference of postoperative bleeding time and bleeding rate between tonsillectomy by the low temperature plasma and the traditional cold surgical devices in 2-14 years old children. Plasma group contained the tonsillectomy by low temperature plasma between the March in 2012 to the August in 2013. Traditional group contained the tonsillectomy by traditional cold surgical devices between the March in 2005 to the August in 2006.
  
  
  RESULTS
  In the 1,000 cases of plasma group, 19 cases occurred postoperative hemorrhage, the hemorrhage rate was 1. 9%. Four cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 0. 4%. Fifteen cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 1. 50%, the bleeding time was 2-13 days after operation, the average number was 7. 5 days. Nine cases had wound infection and 6 cases had eaten some food improperly in these 15 cases. And in these eaten improperly cases, 4 children had eaten fruit and hard food, 2 children had eaten a little food who lost their weight. In 860 cases of the traditional group, 29 cases occurred postoperative hemorrhage, the hemorrhage rate was 3. 37%. 26 cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 3. 02%. Three cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 0. 35%, the bleeding time was 2-6 days, the average number was 4 days.
  
  
  CONCLUSIONS
  It is preferable for chileren to having low temperature plasma tonsillectomy. The causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children are probably related to the postoperative infection, the differences of operation skills, the method of stop bleeding, eating the wrong foods, irritating cough, improper nursing and so on.
