About this study

Thoracotomy is frequently performed in thoracic surgery. It is widely accepted that thoracotomy causes severe acute pain. Many factors such as postoperative analgesia treatment plan, operation time, number of chest tubes, and duration of chest tube stay can affect acute pain. This acute pain 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.

This study aims to analyze the symptoms of chronic pain in the 3rd and 6th months postoperatively in patients who had undergone thoracotomy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Thoracotomy applicationProcedure or surgery

    The chronic pain findings of the patients who underwent thoracotomy will be questioned at the postoperative 3rd and 6th months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Chronic pain symptoms at 3rd months.

    Chronic 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.

    Measured: Chronic pain symptoms at 3rd months.

  2. Chronic pain symptoms at 6th months.

    Chronic 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.

    Measured: Chronic pain symptoms at 6th months.
