title: [Postoperative pain therapy after tonsillectomy in children. An observational study for 7 days].
abstract: OBJECTIVE
  We investigated the efficacy and side-effects of a concept for pain therapy after tonsillectomy in children.
  
  
  METHODS
  A total of 100 children aged between 6 and 14 years were treated according to the following protocol for pain therapy after tonsillectomy: after induction of anaesthesia the children received 35-40 mg/kg acetaminophen rectally and 0.1 mg/kg piritramide i.v.. Additionally, boluses of 0.05 mg/kg pitritramide i.v. were allowed in the recovery room and 2 doses of 20 mg/kg acetaminophen were given rectally every 6 h on the day of surgery. On the following day the children received 30 mg/kg acetaminophen 3 times per day and from the second postoperative day onwards 1 mg/kg diclofenac was given 3 times a day. The rescue therapy was 5 mg/kg metamizol orally. The severity of the postoperative pain was evaluated by a visual pain scale (VAS) (0-100), side-effects such as vomiting and postoperative haemorrhage were documented. The Friedman test was used for testing the time course of pain intensity.
  
  
  RESULTS
  The median of the VAS was 42 on the day of surgery, 35 on the first postoperative day and fell continuously to 10 by the 6th postoperative day. The decrease of pain severity was statistically significant (p <0.05). A rescue therapy was necessary in 6 patients on the day of surgery and in 9 patients on the first postoperative day. 7 patients suffered a postoperative haemorrhage, 4 out of the 7 needed a surgical revision and 2 out of 100 patients vomited.
  
  
  CONCLUSIONS
  We conclude that this protocol for pain therapy after tonsillectomy was effective. The incidence of postoperative haemorrhage and vomiting was low.
