BackgroundMinimally invasive repair of pectus excavatum (MIRPE) is associated with less tissue trauma; however, it may result in increased postoperative pain. Pain experience is a known risk factor for the development of posttraumatic stress symptoms, though there are little data on its relationship with long-term psychological outcomes following major surgery in pediatric patients.AimsIn this study, we examined the relationship between immediate postoperative pain and psychological outcomes at 2 weeks and three months after discharge in a cohort of pediatric patients who underwent MIRPE. We sought to determine whether immediate postoperative pain levels were associated with ongoing distress related to aspects of surgery at both time points. We were also interested in how psychological symptoms related to persistent pain concerns.MethodsData on patients undergoing MIRPE across 14 institutions were collected as part of the Society for Pediatric Anesthesia Improvement Network (SPAIN). Patients were contacted at 2 weeks and three months following discharge to track pain levels and assess psychological distress using a self-report questionnaire. Patients were grouped into cohorts based on self-report of distress related to aspects of surgery, nonsurgical distress, or absence of distress.ResultsAnalysis revealed that a higher proportion of children reporting ongoing distress related to surgery at both 2 weeks and 3 months experienced higher immediate postoperative pain levels. A subset of patients with complete data sets for 2 weeks and 3 months (N = 76) was further examined. Among the 47 patients who endorsed surgical distress at 2 weeks, 25 (53.2%) continued to endorse surgical distress at 3 months. Additionally, report of surgical distress at 3 months was associated with longer-term postoperative pain.ConclusionsOur data suggest that, in patients undergoing MIRPE, the presence of distress at 2 weeks and 3 months may be associated with higher immediate postoperative pain levels.© 2020 John Wiley & Sons Ltd.
