Outcome Measures

Primary Outcomes (1)

  • Postoperative opioid consumption

    Each patient was administered analgesics using a PCA (Patient-controlled analgesia) pump containing opioid in normal saline after leaving PACU (Postanesthesia care unit). Opioid cumulative consumption is recorded for 72 hours postoperatively.

    72 hours after surgery

Secondary Outcomes (10)

  • Pain Score (NRS)

    72 hours after surgery

  • Time of First Postoperative Analgesic Requirement

    1 hour after surgery

  • Total Dose of First Postoperative Analgesic Requirement

    1 hour after surgery

  • The incidence of Side Effects

    72 hours after surgery

  • Apfel score

    The 1 day before the surgery

  • +5 more secondary outcomes

Drug: Ropivacaine

Compound lidocaine in quadratus lumborum block

ACTIVE COMPARATOR

After the induction of anesthesia, 0.6% compound lidocaine is used for bilateral quadratus lumborum block in a volume of 20 mL of each side.

Drug: Compound lidocaine

Compound lidocaine and esketamine in quadratus lumborum block

ACTIVE COMPARATOR

After the induction of anesthesia, 0.6% compound lidocaine and 0.4 mg/kg esketamine are used for bilateral quadratus lumborum block in a volume of 20 mL of each side.

Drug: Compound lidocaineDrug: Esketamine
