High Versus Low Dose Serratus Anterior Plane Block After Minimally Invasive Valve Surgery.
Sponsor: Jessa Hospital
Summary
This study aims to compare the efficacy and quality of pain relief provided by the high-dose serratus anterior plane (SAP) block with the standard SAP block in preventing and treating acute postoperative pain after total endoscopic aortic or mitral valve surgery.

Interventions
High dose serratus anterior plane block (2.4 mg/kg patient ideal body weight)
The needle will be introduced in-plane from supero-anterior to postero-inferior until the needle tip is positioned in the plane underneath the serratus muscle (deep compartment). Under continuous ultrasound guidance, 3/4th of the bupivacaine 0.25% plus epinephrine solution will be injected in the deep compartment. After the deep component of the serratus anterior plane block is completed, the needle will be withdrawn to the subcutaneous tissues. The needle will be flattened and advanced in-plane to the plane superficial to the serratus muscles. The remainder quarter of the bupivacaine 0.25% plus epinephrine solution will be injected superficial to the serratus muscles after correct placement of the needle tip is confirmed on ultrasound. In total a dose of 2.4mg/kg patient ideal body weight will be administered. There is a maximal dose of 200 mg adrenalized bupivacaine for patients with an ideal body weight of 83 kg or more.
Low dose serratus anterior plane block (1.2mg/kg patient ideal body weight)
The needle will be introduced in-plane from supero-anterior to postero-inferior until the needle tip is positioned in the plane underneath the serratus muscle (deep compartment). Under continuous ultrasound guidance, 3/4th of the bupivacaine 0.25% will be injected in the deep compartment. After the deep component of the serratus anterior plane block is completed, the needle will be withdrawn to the subcutaneous tissues. The needle will be flattened and advanced in-plane to the plane superficial to the serratus muscles. The remainder quarter of the bupivacaine 0.25% will be injected superficial to the serratus muscles after correct placement of the needle tip is confirmed on ultrasound.
