Comparing Pain Relief Methods to Protect Lung Function After Minimally Invasive Chest Surgery

What this Trial Is About

This research aims to compare two pain relief methods, Erector Spinae Plane Block ESP and Paravertebral Block PVB, for patients undergoing minimally invasive chest surgery called Video-assisted Thoracoscopic Surgery VATS. The study focuses on how these methods affect early lung function after surgery, since pain can make deep breathing difficult and lead to lung problems like collapse and infection, which prolong recovery. Effective pain control is important to help participants breathe better and reduce complications. Participants will receive either the ESP or PVB block before their VATS procedure. Both blocks are performed using ultrasound guidance to ensure precise placement. These regional nerve blocks aim to manage postoperative pain and help preserve lung function. The study compares which block results in smaller changes in lung function tests taken before surgery and at several timepoints after surgery. During the study, lung function tests measuring Forced Vital Capacity, Forced Expiratory Volume, and Peak Expiratory Flow will be done before surgery, and at 0, 6, 24 hours, and before discharge. Pain levels will be assessed using a visual pain scale at multiple times after surgery, along with total narcotic use recorded through patient-controlled analgesia PCA. Researchers will also evaluate participant satisfaction and monitor side effects like nausea. The average hospital stay is about two days, and all these measures help assess pain control effectiveness and lung function recovery.
