What this trial studies

This study aims to evaluate the effectiveness of two different volumes of local anesthetic (20 ml and 30 ml) administered via the serratus anterior plane block for pain management following video-assisted thoracoscopic surgery (VATS). The research focuses on postoperative pain relief, comparing the analgesic effects of these two volumes of bupivacaine. Participants will be adults aged 18 to 65 undergoing elective VATS, and the study will utilize ultrasound guidance for the block administration. The goal is to determine the optimal volume for effective pain control in this surgical context.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 65 with ASA physical status I-III who are scheduled for elective video-assisted thoracoscopic surgery.

Not a fit: Patients who may not benefit from this study include those requiring emergency surgery or those with chronic opioid or analgesic use.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing thoracic surgery.

How similar studies have performed: Previous studies have explored various volumes of local anesthetics for similar blocks, but this specific volume comparison in the context of VATS is less established.
