Consumption of Cisatracurium in different age groups, using a closed loop computer controlled system.

Background: We devised this study to quantify the effect of age on the consumption of cisatracurium under general anaesthesia, using a computer controlled closed loop infusion system. We further investigated this effect on, sufentanil and propofol consumption.

Methods: 74 patients of physical status I and II, requiring general anaesthesia for elective abdominal surgery, were assigned to three groups.
