Celiac plexus block (CPB) was added to the postoperative analgesia plan. CPB: the target nerve is located in the retroperitoneal space, embedded in the fat in front of the aorta, and distributed in a network along the anterolateral wall of the aorta, just at the beginning of the celiac trunk. During direct vision (anterior) block, first expose the upper edge of the pancreas, palpate the abdominal aorta and abdominal trunk, and palpate the pulsation of the common hepatic artery and splenic artery at the level of the abdominal trunk. Use a 25g 6cm puncture needle with an extension tube and a syringe pumped back by an assistant to form a negative pressure, then the needle is inserted into the fat on both sides of the abdominal aorta. If there is no blood or fluid outflow, slowly inject 10ml of 0.5% ropivacaine each side. After pulling out the needle, observe whether there is damage and bleeding. If necessary, use low-energy electrocoagulation to stop bleeding.
The same analgesic plan as the experimental group, except that CPB is not performed.
