Evaluation of Pain Trajectories After Surgery and Their Potential Relationship With Chronicity at 3 Months

Evaluation of Pain Trajectories After Surgery and Their Potential Relationship With Chronicity at 3 Months: a Single-center Prospective Cohort Study

The effective management of acute postoperative pain remains a daily challenge despite the organizational efforts made and the techniques put in place.

Thirty percent of patients who undergo surgery suffer from chronic post-surgical pain, of which 5 to 10% are of severe intensity. Many preoperative, intraoperative, and postoperative factors, related to the patient, the surgical procedure, or the anesthetic technique, have been incriminated as risk factors for chronic post-surgical pain. The severity of acute postoperative pain is recognized as one of the risk factors for the occurrence of chronic post-surgical pain on which we can hope to interact during the peri-operative period.

In this cohort study, we wish to define the typologies of postoperative pain trajectories observed from Day 0 to Day 7 and to estimate the proportion of patients with an abnormal resolution of pain in a model of organization such as that of our institution, in classic hospitalization and in ambulatory care.
