Performance Evaluation of ANI in Patients Under General Anesthesia With Remimazolam

"The purpose of this study is to determine the validity of ANI in patients undergoing surgery with remifentanil and remimazolam.~During this study, remimazolam infusion rate is determined by the pharmacopoeia.~Remifentanil infusion rate is determined based on the patient's vital signs, systemic status and pain levels. And remifentanil is administrated via targeted infusion control using the Minto model.~ANI scores, vital signs, remifentanil infusion rate are collected at predetermined time points according to the protocol from the start to the end of the surgery."
