Association between children's emotional/behavioral problems before adenotonsillectomy and postoperative pain scores at home.

Following adenotonsillectomy, children often experienced moderate to severe pain and sleep problems during the first 3 days at home. Preoperative internalizing problems and parental need for information were independently associated with increased pain at home. Screening for these problems can help to identify vulnerable children and adapt the perioperative analgesic strategy accordingly (which includes preparation, information, and prescription of pain analgesics).
