Design outcomes

Primary

Measure	Time frame
The onset time of neuromuscular block, the degree of the maximum neuromuscular block, and recovery of neuromuscular block during 2 hours are evaluated and compared after rocuronium 0.6 mg/kg iv at the orbicularis oris, corrugator supercilli, and adductor pollicis muscles.	—
