Abstract:
Objective To evaluate and compare the effectiveness of propofol-remifentanil closed-loop and open-loop anesthesia in gynecological laparoscopic operation under bispectral index (BIS) monitoring.Methods Forty female patients undergoing elective gynecological laparoscopic operation were recruited and randomly divided into closed-loop (group Ⅰ) and open-loop (group Ⅱ) groups.During anesthesia maintenance,the closed-loop group was administered with a BIS-feedback system to regulate the target effect-site concentration;whereas,the open-loop group was administered the target effect-site concentration according BIS value manually.The variation of non-invasive mean arterial pressure (MAP),heart rate (HR),SpO2,BIS,extubation time,consumption of propofol and remifentanil,Ramsay index,and subjective comfort grade were recorded at the selected time points.Results The extubation time in group Ⅰ was shorter than in group Ⅱ.The total dosage of propofol administered in group Ⅰ was less than that in group Ⅱ,but there was no significant difference in the total consumption of remifentanil.HR in group Ⅰ was steadier than in group Ⅱ.However,the MAP and Ramsay index were similar in both the groups.The subjective comfort grade in group Ⅰ was higher than in group Ⅱ.Conclusion The use of propofol-remifentanil closed-loop system by BIS-feedback anesthesia is safer,more controllable,with higher degree of satisfaction and sparing side-effects,we therefore recommend it during gynecological laparoscopic operations.
