Active Comparator
S (+)-Ketamine group
Control group
Drug: Conventional therapy + S (+)-Ketamine In principle, there are no specific restrictions on the dosage, mode of administration, timing, and compatibility of S-ketamine hydrochloride injection,but the recommended dosage is given, which is lower than the dosage specified in the instructions. Recommended use and dosage of S (+)-Ketamine: Bolus intravenous injection before skin incision, the dose is 0.1~0.5 mg/kg; Bolus intravenous injection (dose 0.1~0.5 mg/kg) before skin incision +continuous intravenous infusion (dose of 0.1~0.25 mg/kg/h) during operation; Continuous intravenous infusion after surgery with a dose of 0.02~0.1 mg/kg/h for 24~48 h.
Drug: Conventional therapy Receiving conventional therapy without S (+)-Ketamine hydrochloride injection. There is no restrictions in drugs, doses and incompatibility, the researchers can choose appropriate medication regimens based on clinical practice, but other NMDA receptor antagonists are not be allowed to use, such as dextromethorphan and amantadine.
