Prevalence and Risk Factors for Chronic Post-Surgical Pain Following Video-Assisted Thoracic Surgery : The EVATHO Prospective Bicentric Cohort Study.

Chronic post-surgical pain (CPSP) remains a common complication after thoracic surgery and may significantly impair patients' quality of life. Although the widespread adoption of video-assisted thoracic surgery (VATS) has reduced surgical trauma and improved postoperative recovery, a substantial proportion of patients still develop persistent pain. The EVATHO study is a multicenter prospective observational cohort designed to determine the prevalence of CPSP three months after VATS and to identify perioperative factors associated with its development. Adult patients undergoing thoracic surgery by VATS at Montpellier and Nice University Hospitals will be prospectively enrolled. Pain intensity, neuropathic pain characteristics, anxiety, depression, quality of life, and analgesic consumption will be assessed using validated questionnaires during the perioperative period and at 1 and 3 months after surgery. The results of this study may help identify patients at increased risk of CPSP and improve perioperative pain management strategies following thoracic surgery.

Impact of Topical Aromatherapy on Postoperative Quality of Recovery After Lung Resection

The key to early surgery recovery lies in optimal and immediate control of postoperative pain. Despite standard pain management protocols, lung resection is often associated with acute, neuropathic, or chronic pain, compounded by the side effects of morphine-based treatments. In this context, aromatherapy can provide complementary support, both to alleviate pain and to improve the quality of recovery after surgery.

Study of Cardiac Power Index During Supine, Lateral, and Between Left and Right Positions During Two- and One-Lung Ventilation (OLV): Comparison of Hemodynamic Changes After Lung Recruitment Maneuver and Fluid Challenge Among Responders and Non-Responders (SVI, MAP, CPI Changes).

The aim of this trial is to study the changes of the Cardiac Power Index (CPI) during supine and lateral decubitus position in two and one lung ventilation respectively. Moreover, CPI variations will be compared among patients in left versus patients in right lateral decubitus position. A secondary goal is to compare the changes in hemodynamic parameters after a lung recruitment maneuver during one lung ventilation and a fluid challenge test among patients that respond (responders) or do not respond to fluids (non-responders) according to changes of Stroke Volume Index (SVI) and Mean Arterial Pressure (MAP).
