Outcome Measures

Primary Outcomes (2)

  • The area under the broken line of NRS score

    The score of Numerical Rating Scale(NRS) is 0-10, the higher the score, the more severe the pain.

    Hour 0-48 after surgery

  • Opioid consumption

    Total opioid consumption(conversion to equivalent morphine)

    Hour 0-48 after surgery

Secondary Outcomes (11)

  • NRS pain scores

    Hour 0-48 after surgery

  • Time of first rescue analgesia

    Hour 0-48 after surgery

  • The incidence of rescue analgesia

    Hour 0-48 after surgery

  • Recovery time

    Day 0

  • The incidence of unexpected intraoperative events

    Intraoperative

  • +6 more secondary outcomes

Study Arms (2)

S (+)-Ketamine group

EXPERIMENTAL

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: 1. Bolus intravenous injection before skin incision, the dose is 0.1\~0.5 mg/kg; 2. 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; 3. Continuous intravenous infusion after surgery with a dose of 0.02\~0.1 mg/kg/h for 24\~48 h.

Drug: Conventional therapy + S (+)-Ketamine

Control group

ACTIVE COMPARATOR

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.

Drug: Conventional therapy

Interventions

Patients who undergo general anesthesia using S(+)-ketamine hydrochloride for anesthesia induction,maintenance or postoperative analgesia.

Also known as: Conventional therapy + S-ketamine, Conventional therapy + Esketamine
S (+)-Ketamine group

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.

Also known as: Routine treatment
Control group
