Brief Summary

Objective: To explore the effect of etomidate and esketamine on postoperative pain after tonsillectomy in children. Methods: Investigators enrolled 64 children with American Society of Anesthesiologists (ASA) physical status I and II, aged 2-10 years, and scheduled for elective undergoing tonsillectomy with general anesthesia. All the enrolled patients were randomly divided into etomidate and fentanyl group (Group A) and etomidate and esketamine group (Group B). In the etomidate-fentanyl group (group A), 0.3 mg/kg etomidate and 4 µg/kg fentanyl were given at the induction of anesthesia, followed by continuous infusion of propofol at 4-12 mg/kg/h and remifentanil at 3-6 µg/kg/h until the end of the surgery, respectively; in the etomidate-esketamine group (group B), induction of anesthesia with 0.3 mg/kg etomidate and 0.5 mg/kg esketamine , followed by continuous infusion of propofol at 4-12 mg/kg/h and remifentanil at 3-6 µg/kg/h until the end of the operation. Anesthesiologists who were unaware of the grouping recorded the FlACC Pain Scale at 2 h, 8 h, and 24 h after surgery.

Outcome Measures

Primary Outcomes (1)

  • The face, legs, arms, crying, consolability (FLACC) pain scale

    Anesthesiologists who were unaware of the grouping recorded the face, legs, arms, crying, consolability (FLACC) pain scale at 2 hours, 8 hours, and 24 hours after surgery

    at 2 hours, 8 hours, and 24 hours after surgery

Study Arms (2)

Etomidate and fentanyl group

EXPERIMENTAL

In the etomidate-fentanyl group (group A), 0.3 mg/kg etomidate and 4 µg/kg fentanyl were given at the induction of anesthesia, followed by continuous infusion of propofol at 4-12 mg/kg/h and remifentanil at 3-6 µg/kg/h until the end of the surgery, respectively

Drug: Etomidate and fentanyl group

Etomidate and esketamine group

EXPERIMENTAL

In the etomidate-esketamine group (group B), induction of anesthesia with 0.3 mg/kg etomidate and 0.5 mg/kg esketamine , followed by continuous infusion of propofol at 4-12 mg/kg/h and remifentanil at 3-6 µg/kg/h until the end of the operation

Drug: Etomidate and esketamine group

Interventions

In the etomidate-fentanyl group (group A), 0.3 mg/kg etomidate and 4 µg/kg fentanyl were given at the induction of anesthesia, followed by continuous infusion of propofol at 4-12 mg/kg/h and remifentanil at 3-6 µg/kg/h until the end of the surgery, respectively.

Etomidate and fentanyl group
