Clinical Trial Summary

Previous studies have confirmed that limb pain caused by oxaliplatin chemotherapy is related to spinal cord central sensitization - induced hyperalgesia through oxaliplatin activating spinal cord NMDA receptor(N-methyl-D-aspartic acid receptor). The investigators speculate that this may be the same as the mechanism of severe abdominal pain caused by HAIC(Hepatic Artery Infusion Chemotherapy) during oxaliplatin infusion. The analgesic effect of Esketamine is mainly related to its inhibition of NMDA receptor in spinal cord. Therefore, this study hypothesized that Esketamine can inhibit the sensitization of spinal cord center by inhibiting NMDA receptor, so as to alleviate severe abdominal pain during HAIC perfusion, and reduce abdominal pain caused by ischemia and inflammation by TACE(transcatheter arterial chemoembolization) by improving organ perfusion and anti-inflammatory effect, Therefore, it is expected that Esketamine can better alleviate acute severe abdominal pain caused by TACE-HAIC (transcatheter arterial chemoembolization combined with Hepatic Artery Infusion Chemotherapy )treatment than sufentanil, decrease the dosage of opioids, and reduce the incidence and degree of chronic abdominal pain after treatment.
