Validation of the Gendolcat Score for the Prognosis of Chronic Postoperative Pain in Cesarean Section

Study Overview
=================
Brief Summary
-----------------
Chronic post-surgical pain is a problem that has historically been underestimated. Over the last few years there has been a search for strategies to both predict and prevent its occurrence in patients undergoing surgery. The Gendolcat index is the only predictive model that uses only objective pre-surgical variables to assess the risk of suffering chronic post-surgical pain. However, it is only validated for the following surgeries: thoracotomy, hysterectomy and open inguinal hernia. Our aim is to test whether the Gendolcat model is also valid for cesarean section.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Women undergoing cesarean section<br>This study is designed with a single cohort of women who will undergo a scheduled cesarean section | Other: Questionnaire<br>* All patients should complete the following questionnaires: On the day of surgery: Patient registration. Complete medical history. Gendolcat scale (including the Spanish version of the SF-12 scale). Spanish version of the catastrophizing scale.<br>Other: Questionnaire<br>* The investigators should complete a questionnaire during the surgical procedure specifying the anesthetic technique used, drugs and doses used and record any incident during the surgical procedure<br>Other: Questionnaire<br>* The investigators should complete a questionnaire 24 hours after surgery to assess the possible presence of postoperative pain as well as the intensity and need for rescue analgesia.<br>Other: Questionnaire via telephone call<br>* At 3 months, patients will be called and a structured questionnaire will be completed to assess the presence of chronic postoperative pain.<br>Other: Physical examination<br>* Those women who, after the telephone call, are considered to have chronic post-surgical pain will undergo a physical examination to confirm it. The type of pain and its intensity will also be evaluated. The impact on their daily physical activity and quality of life will be evaluated by means of a questionnaire.<br>|

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gendolcat score | The Gendolcat score assesses the likelihood of suffering chronic post-surgical pain | The Gendolcat score will be assessed on the day patients are included in the study | 
| Categoric Pain Scale | These pain scales give people a simple way to rate their pain intensity using a verbal or visual descriptor of their pain. | Done during physical examination will be performed 3 months after cesarean section. | 
| Numeric Pain Scale | Patients are asked to circle the number between 0 and 10, 0 and 20 or 0 and 100 that fits best to their pain intensity | Done during physical examination will be performed 3 months after cesarean section. | 
| Short Edition of the Brief Pain Inventory | Rapidly assesses the severity of pain and its impact on functioning | Done during physical examination will be performed 3 months after cesarean section. | 
| DN4 Questionnaire | To estimate the probability of neuropathic pain | Done during physical examination will be performed 3 months after cesarean section. |
