Bispectral Index Monitoring During Laparoscopic Cholecystectomy Were Observed In The Operation Application

Obsjective: The ideal is to provide safe, painless anesthesia, muscle relaxation, for patients without known and adverse reactions in operation in good condition to complete the surgery. General anesthesia is suppressed by anesthesia drugs on the central nervous system, so that the patient was disappeared, also will give breathing, anesthesia method brings certain influence in circulation and other important system. Bank of China during general anesthesia anesthesia depth monitoring can effectively prevent the risk of hemodynamic changes and potentially prevent intraoperative body movement, eliminate intraoperative memory and control the intraoperative anesthetic dosage. In recent years, depth of anesthesia monitoring technology has made great progress. As the bispectral index(BIS), evoked potential, entropy index, anesthesia trend(Narcotrend, NT) monitor depth of anesthesia and the brain function state in which(Cerebral State Index, CSI), spectral edge frequency(Spectral edge frequency, SEF), the central frequency(Median frequency, MF), currently the most widely used is the bispectral index, mainly reflecting cortical excitatoryOR inhibitory state, is highly related to the magnitude of BIS and sedation, consciousness, memory, can be very good sedation depth monitoring components in the maintenance of anesthesia is more stable. Methods: The method of anesthesia in two groups were treated with conventional full intravenous anesthesia scheme, recording the basic value, were randomly divided into A(control group), B group(experimental group) two, anesthesia was maintained with propofol, atracurium, sufentanil intravenous infusion. Comparison of two groups of patients were recorded before anesthesia, skin incision, T1 began to T2 T3 T4, after the operation of free gallbladder, extubation immediately before T5, monitoring point 5min T6 after extubation mean arterial pressure(MAP), heart rate(HR) changes. Comparison of two groups of self starting of anesthesia to operation on patients with awake tracheal extubation time and spontaneous breathing recovery time. From the comparison of anesthesia propofol, sufentanil start to the end of the operation, atracurium dosage. Compared with the general situation of two groups of patients such as age, gender, weight, operation time. The incidence of awareness were compared in two groups. Results: Free of gallbladder and extubation in group BIS, MAP, HR value and the control group there is a statistically significant difference(P<0.05), the rest of the time points of two groups of MAP and HR values had no statistical difference(P>0.05), anesthesia breathing recovery time and extubation time when compared with the control group had statistical difference(P<0.05), the dosage of propofol with propofol dosage less than that in the control group, the difference was statistically significant(P<0.05), while the experimental group and remifentanilatracurium dosage is less than that of the control group and remifentanilatracurium dosage but the difference was not statistically significant(P>0.05). The incidence rate was lower than the control group the incidence of intraoperative awareness awareness in experiment group, the difference was statistically significant(P<0.05). Conclusion: the application of bispectral index for monitoring depth of anesthesia in patients with feedback control of intraoperative vital signs should be compared with the traditional method in patients with stable, spontaneous breathing recovery time and pulling out the tracheal catheter time should be shorter, the incidence of awareness should reduce intraoperative anesthetic drug, especially a sedative to less.
