Consumption of Cisatracurium in different age groups, using a closed loop computer controlled system.
Ontology highlight
ABSTRACT: 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.74 patients of physical status I and II, requiring general anaesthesia for elective abdominal surgery, were assigned to three groups. Patients in group 1 were aged from 20 to 45, group 2 were from 46 to 64, and group 3 above 65 years old. General Anesthesia was maintained with propofol and muscle paralysis was maintained using a closed-loop computer controlled infusion of cisatracurium. For analgesia, intermittent bolus of sufentanil 10 ?g was given.Cisatracurium consumption in group 1, 2 and 3 were 1.8?±?0.3, 1.6?±?0.4 and 1.3?±?0.4 ?g/kg/min respectively. There was significant difference of cisatracurium consumption between group 1 and 3 (P?=?0.002), and the consumption of cisatracurium in group 3 was less as compared with group 2 (P?=?0.04). The average recovery index of patients in group 1, 2 and 3 were 8.8?±?2.6, 11.5?±?2.9 and 12.7?±?2.5 minutes respectively. There were difference between group 1 and 2 (P?=?0.02). As compared with group 1, the recovery index was still longer in group 3 (P?=?0.001). Patients in group 1, 2 and 3 consumed an average sufentanil 0.4?±?0.1, 0.4?±?0.1 and 0.3?±?0.1 ?g/kg/hr, respectively. There were statistical significant between group 1 and 3 (P?
