摘要
根据麻醉过程中丙泊酚输注的调节方法,将70例ASAⅠ～Ⅱ级、择期于全静脉麻醉(TI-VA)下行腹腔镜胆囊切除术(LC)患者随机分为对照组(C组)和试验组(T组),每组35例:C组维持收缩压(SBP)90～140mmHg,舒张压(DBP)60～89mmHg;T组维持脑电双频指数(BIS)40～60。分别记录两组各时点SBP/DBP、心率、BIS值及丙泊酚用量、拔管和离室时间,并于拔管和离室时进行警觉/镇静评分(OAA/S),术后评定有无术中知晓,探讨BIS对麻醉深度的监测和调控作用。结果表明,T组麻醉过程及复苏期间SBP/DBP及BIS值均较高,而丙泊酚用量减少、拔管和离室时间缩短、OAA/S值较高。因此,BIS可以准确监测和调控TIVA,加快麻醉恢复。
70 ASA Ⅰ～Ⅱ patients undergoing laparoscopic cholecystectomy （LC） were randomly as- signed into controlled group （group C ） and trial group （group T）, 35 patients in each group, according to the rules of regulating propofol＇ s titration during TIVA. The target of group C is to keep SBP/DBP 90 - 140 mm Hg/60 - 89 mm Hg and that of group T is to keep BIS 40 - 60 during anesthesia. The surveying indexes inclu- ding SBP/DBP, HR, BIS, total dosis of Propofol, time to extubate, time to leave operating room and OAA/S （observer＇s assessment of alertness/sedation）. After operation, to evaluate whether awareness during surgery happens. Compared with group C, there are higher SBP/DBP and BIS in group T after induction of anesthesia, during and after operation, but less dosis of propofol and less time of extubation and staying in operating room in group T. These results indicated that TIVA could be more accurately regulated by BIS during LC operation and accordingly the recovery from anesthesia was accelerated and extremely deep anesthesia was avoided.
