Study: NCT02285829

Intervention type: DRUG
Intervention: Rocuronium Bromide, Cisatracurium Besylate
Description: Both Rocuronium Bromide and Cisatracurium Besylate are administered intravenously following induction of anesthesia initially by bolus, and subsequently re-bolused or administered in continuous infusion as clinically indicated to maintain muscle relaxation. Initial doses of Rocuronium range from 0.45 to 1.2 mg/kg IV, and doses for continuous infusion range from 0.01-0.012 mg/kg/min IV. Initial doses of Cisatracurium range from 0.15 to 0.2 mg/kg, and doses for continuous infusion range from 0.5 to 3 µg/kg/min. Following recovery and baseline screw stimulation at TOF \>0.9, the dosing regimen for this study will rely on restarting a continuous infusion, and adjusting the infusion until the desired TOF ratios are reached. Following screw stimulations and data collection, the infusion will be terminated, and neuromuscular blockade allowed to recover.
