POSTOPERATIVE ANALGESIS FOR PAIN MANAGEMENT AFTER THORACOTOMY

Study Overview
=================
Brief Summary
-----------------
Thoracotomy is among the most painful surgical procedures and can cause severe pain. Postoperative pain causes many complications. Therefore, pain management is important in patients undergoing thoracotomy. For this purpose, systemic analgesics are used along with ultrasound-guided nerve blocks in thoracotomy pain. The effectiveness of thoracic paravertebral block and serratus plane block in the treatment of post-thoracotomy pain will be evaluated by comparing their effectiveness and complications on postoperative pain. Since the epidural spread of the thoracic paravertebral block is more effective, the effectiveness of postoperative pain relief will be more effective

Detailed Description
-----------------
Thoracotomy is among the most painful surgical procedures and can cause severe pain. This pain causes postoperative complications in patients who have thoracotomy surgery. Uncontrolled pain can cause respiratory and thromboembolic events. Therefore, effective pain management is important in patients undergoing thoracotomy. We aim to compare the analgesic effectiveness and complications of thoracic paravertebral block and serratus anterior plane block in relieving thoracotomy pain, which is one of the most painful surgical procedures. It is aimed to compare the effectiveness and complications of thoracic paravertebral block and serratus plane block in postoperative pain control after thoracotomy. Providing pain control reduces postoperative complications and reduces hospital stay, which increases patient comfort and reduces costs. In our research, postoperative morphine consumption after block applications will be compared, and patients' analgesic needs will be evaluated according to their VAS score. Post-operative 3rd, 6th, 9th, 12th, 24th. Morphine consumption will be evaluated by monitoring the hours. It will be evaluated whether there is a need for additional analgesics. During the operation, the patient's heart rate, blood pressure, saturation and temperature variable values will be closely monitored. Standard monitoring methods will be used when examining these parameters.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Morphin consumption | Patient in both groups will provide with intravenous patient-controlled analgesia device containing morphine for postoperative analgesia | during postoperative 24 hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual Analogue Scale (VAS) | Visual Analogue Scale (VAS) requires the patient to rate their pain on a defined scale.For example , 0-10 where 0 is no pain and 10 is the worst pain imaginable | during postoperative 24 hour |
