About this study

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).

Treatment and study plan

Telephone conctact at 3 months

Other

Patients will be contacted at 3 months post-surgery for pain questionnaires.

In hospital pain evaluation

Other

Patients will evaluate their pain levels via a verbal numerical scale on days 1(or-1), 2, 3, 4, 5, 6 & 7.

In hospital questionnaires

Other

Patients are required to fill out the HADS and PCS questionnaires between on day -1 or +1.

Primary outcomes

  1. The pain trajectory for the first 7 post-operative days.

    Time frame: 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 outcomes

  1. The DN4 questionnaire

    Time frame: month 3

  2. Since the surgery, do you have persistent pain? yes/no

    Time frame: month 3

  3. Is it the same pain before the surgery? yes/no

    Time frame: month 3

  4. Verbal numberical scale for pain (ranging from 0 to 10)

    Time frame: month 3

  5. Have you had complications from your surgery? yes/no

    Time frame: month 3

  6. Hospital Anxiety and Depression Scale (HADS)

    Time frame: day -1 or day +1

  7. Pain Catastrophizing Scale (PCS)

    Time frame: day -1 or day +1

  8. Cumulative consumption of antalgic drugs

    Time frame: day -1 or day +1

  9. Cumulative consumption of antalgic drugs

    Time frame: day 2

  10. Cumulative consumption of antalgic drugs

    Time frame: day 3

  11. Cumulative consumption of antalgic drugs

    Time frame: day 4

  12. Cumulative consumption of antalgic drugs

    Time frame: day 5
