The Effect of Lean Body Weight-adjusted Rocuronium Dose on Intubation Conditions: a Prospective Observational Study

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%.
