Study Description

Brief Summary:

Chronic postsurgical pain had number of prevalence on 20%. Its derivates from risk factors, but recent research provide new potential risk factors to develop chronic postsurgical pediatric pain.

To increase the body of knowledge, an observational study is proposed in pediatric patients undergoing surgical intervention.

Condition or disease	Intervention/treatment
Chronic Postoperative Pain; Pediatric ALL	Procedure: Surgery

Detailed Description:

A cohort of pediatric patients undergoing surgery will be followed at the Maternal and Child Hospital October 12, Madrid. The group of patients that develops post-surgical chronic pain and the group that does not develop it will be observed, and risk factors will be studied.

Before the surgical intervention, the risk factors described in the literature will be analyzed. Children will be followed up to 6 months after surgery.
