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.

Outcome Measures

Primary Outcomes (5)

  • 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.

Study Arms (1)

Women undergoing cesarean section

This study is designed with a single cohort of women who will undergo a scheduled cesarean section

Other: QuestionnaireOther: Questionnaire via telephone callOther: Physical examination

Interventions

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.

Women undergoing cesarean section

At 3 months, patients will be called and a structured questionnaire will be completed to assess the presence of chronic postoperative pain.

Women undergoing cesarean section

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.
