Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigator will examine the effects of opioid free anesthesia in patients undergoing laparoscopic gastrectomy. The investigator expect that opioid free anesthesia will reduce postoperative pain and opioid consumption.

And investigator will analyze the association between postoperative pain and patient's underlying psychological characteristics and pain sensitivity. The investigator anticipate that psychological characteristics and pain sensitivity may be realted to postoperative pain and opioid consumption.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

OFA group

Dexmedetomidine and lidocaine are administered during anesthesia, and opioid is not used. For induction, 1 μg/kg of Dexmedetomidine is administered over 10 minutes and 1mg/kg of lidocaine is administered intavenously (bolus). This is followed by continuous intravenous infusion of dexmedetomidine at a rate of 0.2-0.7 μg/kg/h and infusion of lidocaine at the rate of 1 mg/kg/h.

Group Type EXPERIMENTAL

OFA

Intervention Type DRUG

Dexmedetomidine and lidocaine are administered during anesthesia, and opioid is not used. For induction, 1 μg/kg of Dexmedetomidine is administered over 10 minutes and 1mg/kg of lidocaine is administered intavenously (bolus). This is followed by continuous intravenous infusion of dexmedetomidine at a rate of 0.2-0.7 μg/kg/h and infusion of lidocaine at the rate of 1 mg/kg/h.

Control group

Remifentanil is infused during anesthesia, and target-controlled infusion (TCI) is performed according to the Minto model. During indcution of anestheisa, target concentration of remifentanil is set within 3-5 ng/mL. After intubation, target concentration is adjusted within the range of 2-8 ng/mL.

Group Type ACTIVE_COMPARATOR

Control

Intervention Type DRUG

Remifentanil is infused during anesthesia, and target-controlled infusion (TCI) is performed according to the Minto model. During indcution of anestheisa, target concentration of remifentanil is set within 3-5 ng/mL. After intubation, target concentration is adjusted within the range of 2-8 ng/mL.
