摘　　要：目的探讨脑电双频指数(BIS)调控下七氟烷吸入麻醉在小儿腹腔镜手术中的应用。方法择期行腹腔镜手术的患儿80例,随机分为试验组(I组)和对照组(II组),每组40例。I组通过调控七氟烷呼气末浓度(Etsevo)维持BIS值在40～60,II组维持血压和心率在基础值的±20%波动调控Etsevo,并监测BIS值。记录两组血流动力学变化、BIS值、ETsevo、拔管时间和离室时间。结果 I组麻醉过程中平均动脉压(MAP)和BIS值均高于II组(P<0.05);麻醉维持期I组ETsevo低于II组(P<0.05);I组拔管时间和离室时间都明显少于II组(P均<0.05)。结论 BIS调控七氟烷吸入麻醉能减少七氟烷的用量,维持血流动力学平稳,缩短苏醒和拔管时间,提高麻醉的安全性,在小儿腹腔镜手术中应用是可行的。Objective To study the feasibility of application of bispectral index （BIS） control in sevoflurane anesthesia in pediatric laparoscopic surgery. Methods Laparoscopic hernia repair had been performed in 80 children, they were equally divided into experimental group （group I） and control group （group II）. Patients in group I maintained B IS value at 40 -60 through the regulation of endtidal sevoflurane concentration （ ETsevo）, and patients in group II were maintained with control Etsevo according to fluctuation of basic value ± 20% of blood pressure and heart rate. Hemodynamic changes, BIS value, ETsevo, extubation time and off - room time were recorded in patients of these two groups. Results The mean arterial pressure （MAP） and BIS value during anesthesia in group I were higher than those of group II （ P 〈 0.05 ）, but ETsevo was lower than that of group II （ P 〈 0.05 ） in maintaining anesthesia. Extubation time and off - room time in group I were less than those of group II （ P 〈 0. 05 ）. Conclusion The application of bispectral index control in sevoflurane anesthesia for pediatric laparoscopic surgery can reduce the dosage of sevoflurane and keep steady hemodynamics in children and improve the safety of anesthesia, so its application in laparoscopic surgery for children is safe and feasible.
