Abstract 【Objective】To discuss the influencing factors of chronic pain in patients after thoracotomy via thoracoscope. 【Methods】One hundred and eighty patients treated by thoracotomy via thoracoscope in our hospital from January, 2012 to January, 2015 were chosen as the study subjects. The preoperation data, data during operation, preoperation acute pain assessment, and postoperation and followup status on pain postdischarge were analyzed. The influencing factors of patients with chronic pain after thoracotomy via thoracoscope were analyzed by single factor and Logistic regression analysis. 【Results】One hundred and eighty patients treated by thoracotomy via thoracoscope were brought into the study; 164 patients finished the 3 months followup and were divided into an observation group and a control group according to the presence or lack of chronic pain after thoracotomy via thoracoscope. Some differences in data between two groups were statistically significant (P<0.05). This data included sex ratio, time of circulation assistance and aorta occlusion, time of operation, postoperative analgesia, NRS score at rest and during activity 1~5 days after surgery, and so on. Other differences of data between two groups were not statistically significant (P>0.05). These included age, BMI, smoking, drinking, dosage of fentanyl during surgery, time of thoracic close drainage, and hospital stays after surgery. The results of Logistic regression analysis showed that being female, receiving postoperative analgesia, and the pain degree during activity 1~5 days after surgery were the significant influence factors for patients with chronic pain after thoracotomy via thoracoscope. 【Conclusion】Pain degree during activity 1~5 days after surgery is the most preventable factor for chronic pain after surgery. The control of acute pain after surgery can help to reduce the occurrence of chronic pain after surgery.
