Incidence of Chronic Pain After Thoracic Surgery

Recruiting

• Conditions: Postoperative Pain; Video-Assisted Thoracoscopic Surgery; Postoperative Pain, Acute; Postoperative Pain, Chronic; Thoracotomy

• Registration Number: NCT05145153
• Lead Sponsor: Atatürk Chest Diseases and Chest Surgery Training and Research Hospital

Brief Summary

Thoracotomy and video-assisted thoracic surgery procedures are frequently performed in thoracic surgery. It is widely accepted that thoracotomy causes severe acute pain. This prolongs the discharge time of the patients, and increases the frequency of postoperative pulmonary complications and postoperative morbidity. Postoperative acute pain may cause chronic thoracotomy pain in the later period, and may adversely affect the quality of life of the patients. Video-assisted thoracic surgery (VATS) has become the standard procedure in minor and major lung surgeries. Postoperative pain is seen in patients undergoing VATS, although it is not as severe as after thoracotomy. As in thoracotomy, this affects the postoperative pulmonary complications and the discharge time of the patients. Likewise, this pain can cause chronic pain.

In this study, it was aimed to analyze the symptoms of chronic pain in the 3rd and 6th months postoperatively in patients who had undergone thoracic surgery.

Primary Outcome Measures

Name	Time	Method
Pain scores at 3th months.	Chronic pain symptoms at 3th months.	Choronic pain symptoms will be assessed using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Neuropathic pain symptoms (Burning, stabbing, electric shock-like pain, tingling, numbness, pins and needles feeling, hyperalgesia, allodynia, and hypoesthesia) will also be asked to the patients in the 3rd month after surgery.
Pain scores at 6th months.	Chronic pain symptoms at 6th months.	Choronic pain symptoms will be assessed using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Neuropathic pain symptoms (Burning, stabbing, electric shock-like pain, tingling, numbness, pins and needles feeling, hyperalgesia, allodynia, and hypoesthesia) will also be asked to the patients in the 6th month after surgery.

Secondary Outcome Measures

Name	Time	Method
Life quality	The effect of chronic pain on quality of life at 3rd and 6th months.	It will be questioned whether chronic pain affects the patient's quality of life.; 1. has no affect; 2. has little effect; 3. has medium affect; 4. has a lot of affects
