Background/PurposeChronic postoperative pain is a well-established clinical phenomenon that is associated with adverse outcomes. The incidence of this clinical phenomenon in children, however, is not well established. The purpose of this study was to identify the incidence of chronic pain in children after surgery.MethodsFollowing a screening process, a total of 113 children and their parents were enrolled in this cross-sectional study. Data regarding persistence and characteristics of pain after surgery were obtained.ResultsApproximately 13% of the children, most of whom underwent orthopedic procedures, reported the existence of symptoms of chronic postoperative pain. Most of the children indicated that the pain started immediately after surgery, was localized to the surgery site, and was intermittent. Children reported a median duration of pain of 4.1 months, and approximately half of the children experienced pain most days of the week. Up to 30% of the children reported interference of pain in functioning in areas such as extracurricular activities and sleep.DiscussionGiven the large number of children at risk for experiencing chronic postoperative pain, preventative efforts are necessary. Large-scale cohort prospective studies are needed to confirm the results of this cross-sectional study.Copyright © 2011 Elsevier Inc. All rights reserved.
