Gude P, Geldermann N, Georgevici AI, et al. - As the optimal pain therapy for children undergoing tonsillotomy remains unknown, researchers conducted this prospective observational study to assess a standard pain therapy that included the alternating application of ibuprofen and paracetamol. The pain intensity of 81 in-patients aged 2 to 12 years after tonsillotomy was assessed three times daily (mean observation 3.85 days) using the Children’s and Infants’ Postoperative Pain Scale (CHIPPS) in children < 5 years, or with the Faces Pain Scale-Revised (FPS-R) in older children. In addition, the Parents' Postoperative Pain Measure (PPPM-D) was completed by the parents. Overall, 45.7% of children required rescue medication (RM) either in the recovery room or on the ward. On the ward, 30.9% of the children had an indication for RM. Although the pain therapy concept was effective from the first postoperative day, it needs to be improved for the day of surgery. Overall, there was little agreement between the PPPM-D and the CHIPPS or the FPS-R. Fever could be a confounder in measuring pain intensity with the PPPM-D.
