About this study

Numerous studies have confirmed that regional analgesia using peripheral nerve block has great potential for perioperative analgesia in abdominal surgery. Ultrasound guided costal margin block (CMB) is a new regional anesthesia technique that has been proven to compensate for the analgesic effects of regional analgesia techniques such as transverse abdominal muscle plane (TAP) and rectus abdominis sheath (RSB) on mid abdominal incisions, but it is difficult to meet the analgesic needs of anterior and outer abdominal wall incisions. According to relevant anatomy and research, the application of local anesthetics along the rib margin under the rectus abdominis muscle or under the external oblique muscle on the rib surface can block the lateral and anterior cutaneous branches of the thoracoabdominal nerve, known as CMB. Ultrasound guided CMB requires the injection of local anesthetics onto the surface of the rib along the plane below the rectus abdominis and oblique muscles, covering most of the upper abdominal incision pain. However, there are few reports on other types of upper abdominal surgeries such as liver, gallbladder, and pancreas surgeries. Bupivacaine liposomes are an important innovation, which encapsulate bupivacaine in polycystic liposomes using DepoFoam technology to achieve slow drug release and effectively prolong pain relief time by up to 72 hours. This ultra long acting local anesthetic has significant advantages in reducing opioid use, improving analgesic sa…
