Sugammadex ED90 Dose in the Obese Patients

Summary

The purpose of this study is to determine the minimum effective dose of sugammadex, an antagonist of neuromuscular blockade used during anesthesia practice, in obese patients, considering that sugammadex is indicated in adults with normal weight at a dose of 2 mg/kg but no studies were found with obese patients.
