Characterization of Post-operative Pain Trajectories Over Seven Days and Links With Chronicity

Completed

• Conditions: Surgical Procedures, Operative; Chronic Pain; Pain

• Registration Number: NCT02599233
• Lead Sponsor: Centre Hospitalier Universitaire de Nīmes

Brief Summary

The main objective of this study is to establish the postoperative "pain pathways" observed from D1 to D7 in the context of the current management after orthopedic, digestive, obstetrics and gynecology, urology, neurosurgery, vascular and thoracicn surgeries.

Detailed Description

The secondary objectives of this study are:

A. To assess the incidence of Post-Surgical Chronic Pain (PSCP) Chronic 3 months post intervention.

B. To asses the incidence of neuropathic type pain (DN4 Questionnaire) at 3 months post intervention.

C. To study the potential links between pain trajectories and the presence or absence of PSCP.

D. To study the potential links between the presence or absence of PSCP and known risk factors for PSCP (patient-related data, data on the surgery, anesthesia data).

Primary Outcome Measures

Name	Time	Method
The pain trajectory for the first 7 post-operative days.	Day 7 post-surgery	The pain trajectory is the vector of 7 verbal numerical pain estimates (from 0 to 10) taken over 7 days (days 1 (or -1), 2, 3, 4, 5, 6 \& 7).; Day 0 is the day of surgery.

Secondary Outcome Measures

Name	Time	Method
The DN4 questionnaire	month 3
Since the surgery, do you have persistent pain? yes/no	month 3
Have you had complications from your surgery? yes/no	month 3
Hospital Anxiety and Depression Scale (HADS)	day -1 or day +1
Pain Catastrophizing Scale (PCS)	day -1 or day +1
Cumulative consumption of antalgic drugs	day 7
Is it the same pain before the surgery? yes/no	month 3
Verbal numberical scale for pain (ranging from 0 to 10)	month 3
