Pupillometry-guided Remifentanil Infusion Versus Conventional Administration in Children

Comparison of Remifentanil Consumption in Pupillometry-guided Versus Conventional Administration in Pediatric Surgery: a Prospective, Randomized Controlled Trial

Our study aims to compare the total intravenous dose of remifentanil per anesthesia hour and body weight in two groups of pediatric surgical patients - an interventional group with remifentanil infusion under pupillometry monitoring, and control group without pupillometry - to figure out whether pupillometry monitoring may reduce remifentanil consumption during anesthesia while providing sufficient analgesia for surgical noxious stimuli.
