Conditions
Brief summary
This study aims to evaluate effects of magnesium sulfate on onset and duration of low dose rocuronium, intubation condition and surgical condition in patients undergoing laparoscopic cholecystectomy.
Interventions
Patients in each group receive Magnesium sulfate 30 mg/kg in 0.9% normal saline (total volume 100 ml) intravenously for 5 min before induction of anesthesia
Patients in each group receive 0.9% normal saline (total volume 100 ml) alone intravenously for 5 min before induction of anesthesia
0.6 mg/kg of Rocuronium given with induction of anesthesia
0.45 mg/kg of Rocuronium given with induction of anesthesia

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The time of onset the action of Rocuronium | Time from injection of Rocuronium till T1 suppression more than 95% up to 10 minutes. | by using the TOF watch nerve stimulator |
| The time at which Maximal suppression | Time from the injection of Rocuronium to T1 maximal suppression time (TOF=0) up to an hour. | by using the TOF watch nerve stimulator |
| Reversal of Rocuronium | Time from injection of Rocuronium till reversal of T1 (TOF=25%) around an hour after induction of anesthesia | by using the TOF watch nerve stimulator |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intubation condition | Within 10 minutes after induction of anesthesia | to score intubation condition on the basis of 6 items: Jaw relaxation, laryngoscopy, vocal cord position, moving of limbs, coughing & change in heart rate. |
| Surgical condition | During surgery | to score a surgical condition according to 7 point likert scale |
