The treatment of postoperative pain continues to be inadequate in the investigators practice setting.

Inadequate pain treatment not only contributes to postoperative complications in the short term but can also be a factor that favors the development of chronic postoperative pain and diminishes long-term quality of life. Risk factors that can lead to a transition to chronic pain need to be analyzed.

Condition Intervention
Chronic Postoperative Pain
Procedure: Inguinal herniorraphy.
Procedure: Hysterectomy.
Procedure: Thoracotomy .

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective

Further study details as provided by Fundacion IMIM:

Primary Outcome Measures:
  • Evaluation of chronic postsurgical pain. [ Time Frame: After 3 and 12 months of surgery. ]
    After 3 months a physical examination will take place and after 12 months a follow-up will be reported by phone.

Secondary Outcome Measures:
  • Predictive factors of chronic postsurgical pain. [ Time Frame: After 3 and 12 months of surgery. ]
    Preoperative (psychological factors, preoperative pain, pharmacologic treatment) intraoperative (surgical technic, type of anaestesia) and postoperative(posoperative pain, surgical complications and treatment of postoperative pain).

Biospecimen Retention:   Samples With DNA

Sample collection Five milliliters of venous blood will be extracted from each patient with chronic pain; control samples will come from a DNA bank. All patients must have given their written consent to testing and storage.

- Plasma DNA will be extracted with a BioRobot EZ1 Workstation (Qiagen).
