ABSTRACT
Objective To investigate the regulation effect of bispectral index (BIS) on the depth of total intravenous anesthesia (TI-VA) by comparing with regulating the depth of anesthesia according to the changes of hemodynamics. Methods 60 ASA Ⅰ~Ⅱ patients undergoing laparoscopic cholecystectomy (LC) were randomly assigned into controlled group (group C) and trial group (group T) ,with 30 patients in each group, according to the rules of regulating the titration of propofol during TIVA. The target of group C was to keep SBP/DBP 100 ~ 140mmHg/60 ~ 89mmHg and that of group T was to keep BIS 40 ~ 60 during anesthesia. The measure indexes included SBP/DBP, HR, BIS, total dosis of Propofol, time to extubate, time to leave operating room and OAA/S (observer's assessment of alert-ness/sedation). After operation, we evaluated whether awareness during surgery happens. Results As compared with group C, there were higher SBP/DBP and BIS in group T after induction of anesthesia, during aeroperitonia, immediately after finishing operation and just before extubating endotracheal catheter, but less dosis of propofol and less time of extubation and leaving operating room in group T. The differences had significance (P <0.01). There were no significant differences in the changes of HR between two groups (P >0.05) and no awareness during surgery happened in both groups. Conclusion TIVA regulated by BIS during LC can decrease the dosis of propofol, accelerate the recovery from anesthesia and avoid extremely deep anesthesia and awareness during surgery.
