About this study
Official title: The Effect of Paravertebral Block, Intertransverse Block, and Erector Spinae Plane Block on Postoperative Opioid Consumption and Pain Scores in Video-assisted Thoracic Surgery: a Prospective Observational Study
This present study aims is to compare the effects of ultrasound-guided paravertebral block, intertransverse process block, and erector spinae plane block on postoperative opioid consumption, and pain scores in patients undergoing VATS.
Read the detailed description
Video-assisted thoracic surgery (VATS) has become increasingly popular in Thoracic Surgery due to faster recovery and less postoperative pain compared to thoracotomy. However, although VATS has been reported to cause less postoperative pain than thoracotomy, it has also been shown to significantly increase the risk of acute and chronic postoperative pain, which negatively impacts postoperative pain recovery. Inadequate postoperative pain management can reduce the quality of a patient's recovery and increase the risk of postoperative pulmonary complication. Therefore, controlling pain in patients undergoing VATS is key to ensuring early mobilisation, and minimising the risk of pulmonary complications. Regional anaesthesia techniques are an important part of multimodal analgesia approach in patients undergoing VATS. The aim of the present study is to compare the effects of ultrasound-guided regional anaesthesia techniques on postoperative opioid consumption, and pain scores in patients undergoing VATS.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Paravertebral block groupOther
Before the surgery, ultrasoud-guided paravertebral block will be performed before the surgery under standart anaesthesia monitoring
İntertransverse process block groupOther
Before the surgery, ultrasoud-guided intertransverse process block will be performed before the surgery under standart anaesthesia monitoring
Erector spinae plane block groupOther
Before the surgery, ultrasoud-guided erector spinae plane block will be performed before the surgery under standart anaesthesia monitoring
| Study group | Role | What they receive |
|---|---|---|
| Paravertebral block group | Before the surgery, ultrasoud-guided paravertebral block will be performed Receives: Other: Paravertebral block group | |
| İntertransverse process block group | Before the surgery, ultrasoud-guided intertransverse process block will be performed Receives: Other: İntertransverse process block group | |
| Erector spinae plane block group | Before the surgery, ultrasoud-guided erector spinae plane block will be performed Receives: Other: Erector spinae plane block group |
What is being measured
The primary outcome is the main question the study is designed to answer.
Postoperative opioid consumption
All patients will receive a standard patient analgesia (PCA) protocol after operation. The postoperative opioid consumption will only be recorded.
Measured: 24 hours
Secondary outcomes (2)
Postoperative Numerical Rating Scale (NRS) pain scores
The postoperative pain intensity will be assessed with the Numerical Rating Scale (NRS) score (0=no pain; 10=most severe pain).
Measured: postoperative 24 hours
Chronic pain
Patients will be telephoned 3 months after the surgery and the presence, localization, intensity of the pain , its character, and its relation with rest and/or activity will be recorded by asking only verbally.
Measured: 3 months
