- 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.

Group Intervention Description Superficial Serratus Anterior Plane Block Superficial Serratus Anterior Plane Block Superficial 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 Block Deep Serratus Anterior Plane Block Deep 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
Name Time Method Intraoperative remifentanil consumption through study completion, an average of 1 year Intraoperative remifentanil consumption will be checked.
- Secondary Outcome Measures
Name Time Method Dose of rescue drugs used to control blood pressure and HR through study completion, an average of 1 year Dose of rescue drugs used to control blood pressure and HR will be checked
Postoperative pain: numeric rating scale 30 minutes later operation Postoperative pain will be evaluated using a numeric rating scale (0 being no pain, 10 being worst pain imaginable)
Emergence time through study completion, an average of 1 year Emergence time is duration between the end of surgery and extubation. Emergence time will be checked.
Systolic blood pressure through study completion, an average of 1 year Systolic blood pressure (mmHg) will be checked
Heart rate (HR) Heart rate through study completion, an average of 1 year Heart rate (beats per minute) will be checked
