In this study, researchers wiil administer rocuronium, based on either the lean body weight or the total body weight in patients with body mass index (BMI) of 18.5 to 34.9 and compared the duration of action of the drug and its effects on tracheal intubation conditions and hemodynamic parameters..

The whole body will be routinely monitored with electrocardiogram, oximetry oximetry, and non-invasive arterial monitoring. For anesthesia induction, intravenous (IV) fentanyl 50-100 µg and propofol 2mg/kg will be ventilated 100% by lightning. After optimal general anesthesia was achieved, the ulnar nerve was adapted and monitored at the wrist with TOF-Watch® SX (Organon, Swords Co., Dublin, Ireland). LBW lower content of 0.6 mg/kg rocuronium will be administered. K subgrade similar a dose based on TBW will be administered. The time to duration of rocuronium TOF responses will be measured (T1 (seconds)). All consumers will be intubated with a Macintosh laryngoscope diameter with endotracheal sold with inner tubes of 7.5 8.0 mm and 7 mm to 7.5 mm. A single air anesthetist will evaluate the intubation target according to the Han-Raulo intubation scoreboard. Anesthesia will be provided with sevoflurane and an additional dose of phenyl. Monitoring with TOF was continued until the initial fasciculation power (T2=min) of the adductor pollicis decreased to 25% and was approached to an additional rocuronium dose of 0.3mg/kg. All anesthetic agents for operation will be discontinued and extubated when the TOF value reaches 90%.
