| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Opioid anesthesia group | Other | Anesthesia induction with propofol 2.5mg/kg, rocuronium bromide 0.6mg/kg, sufentanil 0.3μg/kg, intubation was performed when BIS value reached 40-60. Intraoperative pump injection of propofol 4-12 mg/kg·h and remifentanil 0.2-0.5 μg/kg·min to maintain anesthesia. Ultrasound-guided transversus abdominis plane block (with 0.375% ropivacaine 40ml) will be implemented preoperatively. Ondansetron 8mg and sufentanil 10 μg will be given after surgery. For PCA, sufentanil 2μg/kg + dexmedetomidine 2μg/kg + ondansetron 24mg. |

| Opioid free anesthesia group | Experimental | Anesthesia induction with propofol 2.5mg/kg, rocuronium bromide 0.6mg/kg, naborphine 0.2mg/kg，esketamine 0.3mg/kg, intubation was performed when BIS value reached 40-60. Intraoperative pump injection of propofol 4-12 mg/kg·h and esketamine 0.3～0.5mg/kg·h. Ultrasound-guided transversus abdominis plane block (with 0.375% ropivacaine 40ml) will be implemented preoperatively. Ondansetron 8mg and naborphine 0.2mg/kg will be given after surgery. For PCA, naborphine 2mg/kg + dexmedetomidine 2μg/kg + ondansetron 24mg. |

| Measure | Description | Time Frame |
|---|---|---|
| postoperative NRS score | A subjective psychometric response scale used to measure distinct behavioral or physiological phenomena based on linear numerical gradient or yes/no alternatives. The Numeric Pain Scale (NRS) pain numerical score(0-10 score, 0: no pain, 10: worst imaginable pain). A pain measurement list about quiet NRS score and cough NRS score at different postoperative time will be used. | Score from the end of the operation and follow-up at the time point specified in the scoring form for a total of 27 hours. |
| Measure | Description | Time Frame |
|---|---|---|
| Dosage of remedial analgesics postoperatively | If the participant still feels severe pain after operation and needs additional analgesic drugs for treatment, we will record the type and dose of drugs used by the patient. | It takes about 24 hours. |
| Hemodynamic fluctuation |

Hemodynamic fluctuation during perioperative period. The levels of SBP in mmHg, DBP in mmHg, MAP in mmHg and HR in times/minute in basic(T0), after induction(T1), preoperative(T2) and after establishing pneumoperitoneum(T3) 1h after the pneumoperitoneum(T4) and Immediately after operation(T5), Before(T6) and after(T7) extubation were recorded. |
| From the beginning of the general anesthesia induction to the time leaving PACU, it takes about 4 hours. |
| Ramsay scale | Ramsay scale is the most widely used sedation scoring standard in clinic, which is simple and practical. This scale has multiple advantages: it is reproducible, easily executed and has good applicability. This has made the scale the most widely used to assess level of sedation for procedures in pediatrics. It is divided into six levels(1-6): 1 shows patient is anxious and agitated or restless, or both; 2 shows patient is co-operative, oriented, and tranquil; 3 shows patient responds to commands only; 4 shows patient exhibits brisk response to light tactile stimuli or loudauditory stimulus; 5 shows patient exhibits sluggish response to light tactile stimuli or loud auditory stimulus; 6 shows patient exhibits no response. | Score from the end of the operation and follow-up at the time point specified in the scoring form for a total of 27 hours. |
| recovery time | From the time when the patient entered PACU to the time when the participant meets the standard of leaving the PACU. | It will take up to 1 hour or 2 hours. |
| The levels of C-reactive protein (CRP) | We will collect the participant's blood at the time before surgery(T0), after surgery(T1), and 24h after surgery(T2) to obtain the levels of C-reactive protein (mg/L). | It takes about 24 hours. |
| The levels of cortisol (COR). | We will collect the participant's blood at the time before surgery(T0), after surgery(T1), and 24h after surgery(T2) to obtain the levels of cortisol (nmol/L). | It takes about 24 hours. |
| The levels of blood glucose (BG) | We will collect the participant's blood at the time before surgery(T0), after surgery(T1), and 24h after surgery(T2) to obtain the levels of blood glucose (mmol/L). | It takes about 24 hours. |
| The levels of interleukin-6 (IL-6). | We will collect the participant's blood at the time before surgery(T0), after surgery(T1), and 24h after surgery(T2) to obtain the levels of IL-6 (pg/mL). | It takes about 24 hours. |
| Scores of 15-item Quality of Recovery (QoR-15) scale 24 hours postoperatively of participants. | The QoR-15 scale is a validated tool to assess the quality of postoperative recovery (QoR) from 0 to 150. The QoR was classified as excellent (QoR-15 > 135), good (122 ≤ QoR-15 ≤ 135), moderate (90 ≤ QoR-15 ≤ 121) or poor (QoR-15 < 90). | One day after the surgery. |
| Rate of postoperative nausea and vomiting | Postoperative nausea and vomiting will be recorded if it happens. | It takes about 24 hours. |
| Acceptability of participants with laryngeal mask 24 hours after surgery. | One day after surgery, we will record the acceptability of laryngeal mask and the degree of postoperative pharyngeal pain of the participants. Acceptability of participants with laryngeal mask will be assessed by whether the participant was willing to receive laryngeal mask anesthesia again. Pharyngeal pain can be evaluated using the Numeric Pain Scale (NRS) pain numerical score. A subjective psychometric response scale used to measure distinct behavioral or physiological phenomena based on linear numerical gradient or yes/no alternatives. The Numeric Pain Scale (NRS) pain numerical score(0-10 score, 0: no pain, 10: worst imaginable pain). | One day after the surgery. |
