To assess whether bispectral index-controlled administration of magnesium sulfate reduces propofol requirements and affects sedation depth and comfort during colonoscopy.
Enrolled 60 patients assigned to receive either 50 mg/kg magnesium sulfate diluted in 100 mL saline (Group 1) or 100 mL saline alone (Group 2) 10 minutes prior to colonoscopy.
Administered an initial propofol bolus of 0.5 mg/kg with maintenance infusion at 60 mcg/kg/min, titrated to maintain a target bispectral index (BIS) value of 70.
Propofol consumption was significantly lower in the magnesium group than in the saline control group (p < 0.05).
Time required to achieve the target BIS 70 sedation level was significantly shorter in the magnesium group (p < 0.05).
Patient- and endoscopist-satisfaction scores showed no significant differences between the two groups.
