Efficacy of Continuous Erector Spinae Plane Block to Reduce Postoperative Pain in Patients Undergoing Unilateral Thoracotomy

Efficacy of Continuous Erector Spinae Plane Block to Reduce Postoperative Pain in Patients Undergoing Unilateral Thoracotomy

The goal of this clinical trial is to learn if continuous Erector Spinae Plane Block (ESPB) reduces postoperative pain in patients undergoing unilateral thoracotomy. It will also evaluate the safety and effectiveness of continuous ESPB. The total participants needed will be 30 persons. The main questions it aims to answer are:

• Does continuous ESPB lower the intensity of postoperative pain compared to multimodal intravenous analgesia?
• Does continuous ESPB increase the time to first analgesic request?
• Does continuous ESPB reduce the amount of intravenous opioids required in the first 48 hours after surgery?
• Does continuous ESPB improve the overall recovery quality within 48 hours post-surgery?

Participants will:

• Receive continuous ESPB or multimodal intravenous analgesia after the surgery.
• Undergo routine pain assessments, and recovery evaluations using tools like the Visual Analogue Scale (VAS) and Quality of Recovery-15 (QoR-15).
• Participate in follow-up visits for data collection on pain, opioid usage, and recovery quality.

For the Continuous ESPB Group, patients will receive continuous ESPB, NSAIDs, Paracetamol, and Morphine using Patient Controlled Analgesia (PCA) with a demand only mode.

For the Intravenous Opioid, patient will receive Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), Paracetamol, and Morphine using Patient Controlled Analgesia (PCA).
