About this study
The aim of this retrospective study is to determine the factors affecting the development of chronic pain in patients with thoracotomy in the Thoracic Surgery Operating Rooms of İbn-i Sina Hospital. By identifying these factors, it is aimed to apply the necessary treatments to prevent the development of chronic pain and to improve patient outcomes.
Read the detailed description
The study included 229 patients ASA 1, 2 and 3, 18 years of age and older, who underwent elective thoracotomy in Ankara University İbn-i Sina Hospital, Thoracic Surgery operating room between 01.01.2016 and 31.12.2020. The medical files and electronic records of the patients were scanned from the system. Age, gender, weight, ASA score, smoking, comorbidities (hypertension, diabetes), drug use, malignancy, chemotherapy history, radiotherapy history, intraoperative and postoperative analgesia method, duration of acute pain, type of surgery, duration of surgery, duration of anesthesia, rib resection, number of chest tubes and duration time, time to apply to the pain clinic, and the analgesic method applied were recorded.
