Combine Serratus Anterior Plane Block Versus Erector Spinae Plane Block in Coronary Bypass Surgery

Comparison of Postoperative Analgesic Efficacy of Combine Serratus Anterior Plane Block and Erector Spinae Plane Block in Coronary Bypass Surgery: Randomized Controlled Study

Even though Erector Spinae Plane (ESP) Block is shown to be efficient in cardiac surgery, the Combine Serratus Anterior Plane (CSAP) Block is still controversial if it has an efficient analgesic effect for sternotomy and drain tube pain relief. This study aims to compare ESP block and CSAP block for postoperative analgesia in coronary bypass surgery patients.

Acute postoperative pain after cardiac surgery originates various surgical procedures that may cause pain including the incision of tissues, sternotomy, the separation of bone-joint structures, the severity and duration of these applications, the use of chest tubes, and the patient's personal inflammatory may affect the response to these stimuli. Postoperative pain is a critical risk factor for the development of pulmonary and cardiovascular complications such as atelectasis, cardiac ischemia, and arrhythmias. Researchers claim that adding techniques to iv drugs, such as thoracic epidural anesthesia, paravertebral block, or erector spinae plane block (ESP) to multimodal analgesia regimens positively affect recovery. Although the efficacy of ESP block in providing postoperative analgesia has been demonstrated in many studies, there is no study comparing CSAP and ESP block in cardiac surgery.

An erector spinae plane block will be performed at the level of the 5th thoracic vertebrae with 30 mL of 0.25% bupivacaine solution under ultrasound guidance before the operation.

Combine Serratus Anterior Plane block will be performed at the level of 5th costa with 30 mL of 0.25% bupivacaine (15 mL superficial serratus plane block and 15 mL deep serratus plane block) solution under ultrasound guidance before the operation.
