Brief Summary

This study evaluates the difference of deep and superficial serratus anterior plane block on intraoperative opioid consumption, emergence time and hemodynamic stability in patients undergoing video-assisted thoracic surgery.

Detailed Description

Thoracotomy is known as one of the most painful surgery. Thus, there is a development to reduce surgical stress in terms of operation technique, which is video-assisted thoracoscopic surgery. Although it has reduced postoperative pain and complications compared with thoracotomy, VATS is still quite painful operation. Serratus plane block is a novel technique which provide analgesic effect for lateral chest wall by blocking lateral branch of intercostal nerve. Two methods were proposed to target the top and bottom of the serratus anterior muscle. However, the difference of deep and superficial serratus anterior plane block during intraoperative period has not yet been studied.

In this study, therefore, the investigators decided to assess the difference of deep and superficial serratus anterior plane block on intraoperative opioid consumption, emergence time and hemodynamic stability in patients undergoing video-assisted thoracic surgery.

Superficial Serratus Anterior Plane BlockSuperficial Serratus Anterior Plane BlockSuperficial Serratus Anterior Plane Block was performed just before the start of surgery after anesthetic induction through ultrasound-guidance. 20ml of 0.375% ropivacaine was slowly injected between the fascia of serratus anterior and latissimus dorsi near 5th rib.
Deep Serratus Anterior Plane BlockDeep Serratus Anterior Plane BlockDeep Serratus Anterior Plane Block was performed just before the start of surgery after anesthetic induction through ultrasound-guidance. 20ml of 0.375% ropivacaine was slowly injected between the fascia of serratus anterior and external intercostal muscle near 5th rib.
Primary Outcome Measures
