Transition From Acute to Chronic Pain After Inguinal Hernia, Hysterectomy and Thoracotomy: Analysis of Risk Factors and Association With Genetic Polymorphisms

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.
