ABSTRACT
Objective To evaluate the effect of age factor on the sedative efficacy of propofol given by closed-loop infusion in patients undergoing gynecological laparoscopic surgery.Methods A total of 100 patients,weighing 55-75 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective gynecological laparoscopic surgery under general anesthesia,were divided into 2 groups (n =50 each) according to agemiddle-aged group (45-64 yr) and elderly group (65-75 yr).Propofol was given by closed-loop infusion,and the target plasma concentration was automatically regulated to maintain bispectral index (BIS) value within the target range of 45-55.Remifentanil was given by target-controlled infusion at a target plasma concentration of 2-6 ng/ml to maintain anesthesia,and cisatracurium was injected intermittently to maintain muscle relaxation.The total consumption of propofol and remifentanil,regulating frequency of propofol,time ratio of BIS40-60,global score reflecting performance of closed-loop infusion system,emergence time and extubation time were recorded.Results Compared with middle-aged group,the time ratio of BIS40-60 was significantly increased,global score was decreased,the total consumption of propofol and remifentanil was significantly decreased,the regulating frequency of propofol was increased (P<0.05),and no significant change was found in emergence time or extubation time in elderly group (P>0.05).Conclusion The sedative efficacy of propofol given by closed-loop infusion is influenced by age factors when used for gynecologic laparoscopic surgery,and the stability in elderly patients is superior to that in middle-aged patients.
