Conditions

gastroenteric tumor

Interventions

Lumbar multifidus muscle block group on the arcuate ligament:On the basis of routine anesthesia, during the start of the surgery, ultrasound-guided lumbar psoas muscle block on the superior gluteal li
The dexmedetomidine + superior lumbosacral fascia muscle block group:On the basis of routine anesthesia, anesthesia maintenance: add dexmedetomidine at a dose of 0.5 ug/kg/h, and discontinue the drug
before the start of the surgery, perform lumbar paraspinal muscle block on the arcuate ligament under ultrasound guidance (33% ropivacaine 30 mL).
The dexmedetomidine group:On the basis of routine anesthesia, anesthesia maintenance: add dexmedetomidine at a dose of 0.5 ug/kg/h, and discontinue the drug 20 minutes before the end of the surgery.
Control group:Undergo basic general anesthesia
