About this study

This study aims to estimate prevalence and determine risk factors for chronic pain at 3 months post-operative in pediatric surgery.

Read the detailed description

Chronic pain, defined as continuous or intermittent pain for 3 months or more, postoperative because in the territory of the surgical procedure and does not exist before the operation, is common in adults. Its prevalence varies according to the surgeries between 10 and 50% of the operated adults. The factors potentially responsible for their occurrence are gradually being highlighted in the recent literature, which has made it possible to develop an appropriate analgesic management strategy.

In pediatric surgery, acute pain has long been known and treated as early as possible using multimodal analgesic techniques. On the other hand, there are very few studies evaluating postoperative chronic pain 3 months after infant surgery, as was the case a few years ago in adults.

This study aims to estimate prevalence and determine risk factors for chronic pain at 3 months post-operative in pediatric surgery.
