Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

For children, adequate perioperative pain management is a right according to the UN convention on the rights of the child, a law in Sweden since 2020. Despite this, children are still under-treated in many cases. In addition to great suffering, this can lead to missing school and a long-term burden on the society.

ESPA, the European Society for Pediatric Anesthesia, has drawn up guidelines for perioperative pain management. With the study 4P: Persistent Postoperative Pediatric Pain, we want to investigate whether these guidelines are followed and how many children develop long-term pain postoperatively.

In order to map the prevalence of pain after surgery in children in Sweden, the investigators plan to include and follow 2000 children in southern Sweden who undergo surgery. The study provides a unique opportunity to follow a large number of children, evaluate given per- and postoperative pain treatment and identify factors linked to the development of acute and long-term postoperative pain. Our goal is to optimize peri- and postoperative pediatric pain management to promote rapid recovery after surgery.
