Official Title: Effects of Pretreatment With Different Doses of Cisatracurium on Succinylcholine-induced Fasciculations

Brief Summary: To investigate the effects of different doses of cisatracurium pretreatment on succinylcholine-induced fasciculations.

Detailed Summary: Ninety patients scheduled for laparoscopic cholecystectomies were equally randomized into three groups to receive pretreatment of 0.005, 0.01, and 0.02 mg/kg cisatracurium, respectively. General anesthesia was induced 3.5 min later, train of four stimulation was monitored 4.5 min later, succinylcholine 1.5 mg/kg was injected 5 min later, and endotracheal intubation was implemented 6.5 min later. The side effects of cisatracurium, intensity of fasciculations, intubating conditions, time and extent to maximal depression of twitch and time for its recovery to 20% of control value, severity of myalgia at 24 h postoperatively, serum potassium before cisatracurium pretreatments, at intubating time, and 5 min after intubation were recorded.

Current Primary Outcome: Presence of fasciculations [ Time Frame: After the injection of succinylcholine for 1.5 minutes ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Side effects of the pretreatment of cisatracurium [ Time Frame: From the time of 3 minutes after the pretreatment of cisatracurium for 0.5 minutes ]
  • The time to maximal depression of twitch [ Time Frame: From the time of 4.5 minutes after the pretreatment of cisatracurium for two minutes ]
  • The extent to maximal depression of twitch [ Time Frame: From the time of 4.5 minutes after the pretreatment of cisatracurium for two minutes ]
  • The grades of endotracheal intubation [ Time Frame: At intubating time ]
  • The changes of serum potassium [ Time Frame: After entering the operating theater till the anesthesia induction, at intubating, and 5 min after intubation ]
  • Myalgia at 24 hours postoperatively [ Time Frame: At 24 hours postoperatively ]


Original Secondary Outcome: Same as current
