Validity of Pain Threshold Index in Children

Not Applicable

• Conditions: Electroencephalography; Anesthesia, General

• Registration Number: NCT03622242
• Lead Sponsor: Seoul National University Hospital

Brief Summary

Comparison of total infused dose of remifentanil between pain threshold index monitoring group and control group

Detailed Description

Investigators plan to enroll pediatric patients aged between 3 and 12 years old undergoing surgery under general anesthesia with continuous infusion of 2% propofol and remifentanil.

After dividing them into two groups, investigators monitor pain threshold index and wavelet index in test group and adjust remifentanil infusion to maintain both indices in desirable range, while monitoring only wavelet index and adjust remifentanil infusion to maintain wavelet index and conventional vital signs in desirable range in control group.

Investigators compare consumption of remifentanil, time to extubation after surgery, and post-anesthesia care unit length of stay between both groups.
