Brief 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.

Outcome Measures
Primary Outcomes (1)
Sugammadex ED90
Complete reversal of neuromuscular blockade occured when the patient had a TOF T4/T1 ≥ 0.9 within eight minutes of sugammadex infusion. The sequencial design method of up-and-down was applied to determine the minimum effective dose in 90% of patients (ED90). An effective dose is one that achieves complete reversal of neuromuscular blockade that is defined as a measure of TOF equal or higher than 0.9, or a relationship between T4 an T1 measure ≥ 0.9, within eight minutes of sugammadex infusion.

Study Arms (1)
sugammadex ED90
EXPERIMENTALSequential design method up-and-down of the biased coin aimed to determine the minimum effective dose in 90% of patients (ED90). The following doses were chosen: 2.0 mg/kg, 2.2 mg/kg, 2.4 mg/kg, 2.6 mg/kg, 2.8 mg/kg.
Interventions
The first patient received the dose of 2.4 mg/kg and if there was a negative response, the next patient would be allocated to receive the next higher dose of 2.6 mg/kg. In case that 2.4 mg/kg did produce a positive response, the next patient would be randomized with 10% of probability to receive the next dose of 2.2 mg/kg or 90% probability to receive the same dose of 2.4 mg/kg.
Eligibility Criteria
You may qualify if:
- a body mass index ≥ 40 kg/m2
- bariatric surgery
- informed consent signed
You may not qualify if:
- history of neuromuscular diseases,
- use of drugs that could interfere with neuromuscular transmission,
- allergy to neuromuscular agents of the aminosteroids class,
- anticipated difficulty in airway management,
- renal failure
