Multimodal Analgesia in Laparoscopic Radical Gastrectomy With Gastric Cancer: a Multi-center Study

Multimodal analgesia is the name of a procedure or program. Multimodal analgesia doesn't mean different interventions are used. Patients in this group need receive this analgesia program (procedure) instead of one analgesic drug or technology. The program consists of incision infiltration with ropivacaine, intravenous injection of parecoxib, and oral administration of oxycodone/paracetamol mixture.
