Conditions
Brief summary
Obesity has become one of the world's leading health problems. It is known that obesity causes many diseases and negatively affects the quality of life. For this reason, many conditions that are thought to be effective in obesity and concern the quality of life of patients have been scientifically researched and continue to be investigated. One of them is postoperative pain. Although there are studies stating that there is no relationship between body mass index (BMI) and postoperative pain, when the literature data is examined, it is thought that obesity is a risk factor for postoperative pain and changes pain sensitivity and analgesic needs of patients. There are also studies in the literature stating that the level of postoperative pain increases in parallel with each unit increase in BMI. After thoracic surgery, many analgesic methods have been suggested, including thoracic epidural analgesia (TEA), thoracic paravertebral block (TPVB), intercostal nerve blocks (ICSB), erector spina plane block (ESPB), serratus anterior plane block (SAPB). This study will compare the effects of BMI on postoperative pain in patients undergoing TPVB for postoperative analgesia and thoracoscopic surgery.

| Measure | Time frame | Description |
|---|---|---|
| Pain Scores | 1st hour after surgery. | Pain will be assessed at the first-hour rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Pain assessment will be done at the 1st, 2nd, 4th, 12th, 24th, and 48th hours after surgery. |
