Abstract: 【Abstract】〓Objective〓To explore the sensitivity of the Narcotrend index, Bispectral index and Entropy index in the preschool children during subjected to laparoscopic surgery. Methods〓120 cases of children undergoing elective laparoscopic surgery were chosen and were assigned to 4 groups, Narcotrend index group (N group, n=30), Bispectral index (B group, n=30), Entropy index (E group, n=30) and control group (D group, n=30). After standard intravenous anesthesia induction, the endotracheal tube was inserted for mechanical ventilation,and then inhaled sevoflurane and infused remifentanil to maintain anesthesia. The MAP, SpO2, HR, NTI, BIS, entropy index were recorded in each observation stage between entrance in and out operation room. The operation time, time from stopping infusion drugs to breathe spontaneously were recorded. The dosage of sevoflurane and remifentanil was calculated. Results〓In N group, N value was increased in T3 T4 and T9 moment than in T2 moment (all P values<0.05). Compare with other groups, the recovery time of spontaneous breathing of NTI group was shortened (all P values<0.05), and the dosage of sevoflurane and remifentanil of NTI group was reduced (all P values<0.05). Conclusion〓In preschool children for laparoscopic surgery, Narcotrend index hand the advantage to both bispectral index and entropy index in monitoring anesthesia depth sensitivity, as well as the smaller dosage of anesthetic drugs, shorten the time of awakening, smaller PRST fluctuations.
