Pain Management, Thoracotomy
Conditions
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.
Interventions
PROCEDUREDeep Serratus Anterior Plane Block
Deep Serratus Anterior Plane Block was performed just before the start of surgery after anesthetic induction through ultrasound-guidance.
Superficial Serratus Anterior Plane Block was performed just before the start of surgery after anesthetic induction through ultrasound-guidance.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intraoperative remifentanil consumption | through study completion, an average of 1 year | Intraoperative remifentanil consumption will be checked. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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 |
| 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) |
