title: [Clinical study of post-operative pain following coblation tonsillectomy and/or adenoidectomy in children with sleep-disordered breathing].
abstract: OBJECTIVE
  To explore the characteristics of post-operative pain following coblation tonsillectomy and/or adenoidectomy in children with sleep-disordered breathing (SDB) and explore the correlation between the first day post-operative pain scores and age and operating time.
  
  
  METHODS
  1) A total of 113 SDB children scheduled to undergo coblation tonsillectomy and/or adenoidectomy were recruited. 113 children were divided into two groups according to the method of operation, children who underwent coblation tonsillectomy and adenoidectomy were enrolled in study group one and children who underwent coblation adenoidectomy only were in study group two. Be sides, children of study group one with a history of chronic tonsillitis were in chronic tonsillitis group, children without a history of chronic tonsillitis were in non-chronic tonsillitis group. 2) The parents scored pain in their children on a VAS (anchored by "no pain" at 0 and "worst pain" at 10) in the morning, before using any analgesics and having breakfast, over the first 3 and the seventh post-operative days. 3) Post-operative pain scores were compared between both the study group one and two and chronic tonsillitis group and non-chronic tonsillitis group. Futhermore, the correlation between the first day post-operative pain scores and age and operating time were also analysed.
  
  
  RESULTS
  1) The difference of post-operative pain scores over the first 3 and the seventh post-operative days were significant between the study group one and group two (P<0.05). 2) Non-chronic tonsillitis group were significantly less painful than chronic tonsillitis group on day 1, day 2 and day 7 (z=-2.004, -2.059, -2.334, P<0.05). But there was no significant difference in pain levels on day 3 (P>0.05). 3) The first day post-operative pain scores was correlated with age (r=0.273, P<0.01) and operating time (r=0.423, P<0.01).
  
  
  CONCLUSIONS
  The first day post-operative pain scores was correlated with age and operating time. Children with a history of chronic tonsillitis were more painful than children without the history.
