【摘要】：目的探索全麻术后寒战与肌电图(electromyography,EMG)值之间的相关性。方法选择全身麻醉下行脊柱手术的患者80例。由两位观察者使用VISTA BIS监测仪记录每位患者在麻醉前正常的EMG值;手术结束后继续观察1h,记录首次出现寒战时的EMG值并每隔1min再记录一次,共记录3次;若观察期间患者寒战级别加重,继续如上述方式记录新级别寒战的EMG值。结果共记录有效EMG值224个,其中Wrench寒战分级0级对应52个,其EMG值中位数为42(40~45)分贝;2级对应75个,其中位数是53(50~55)分贝;3级对应58个,其中位数是60(56~63)分贝;4级对应39个,其中位数是64(62~66)分贝。各级别寒战所对应的EMG值差异有统计学意义(P0.01)。全麻术后寒战的级别与EMG值大小具有明显的相关性(r=0.879,P0.01)。结论全麻下脊柱手术术后出现的Wrench寒战级别与VISTA Bis监测仪记录的EMG值具有相关性。使用VISTA Bis监测仪对寒战的发生发展进行监测,可能成为一种新型的、连续的、客观准确的量化性寒战监测方式。
[Abstract]:Objective to explore the correlation between shivering and electromyography (electromyography,EMG) after general anesthesia. Methods 80 patients undergoing spinal surgery under general anesthesia were selected. The EMG values of each patient before anesthesia were recorded by two observers using VISTA BIS monitor, and the EMG values of the first shivering were recorded for 1 hour after operation, and the EMG values were recorded every other time every three times at intervals of 1min for a total of 3 times, and the EMG values of each patient before anesthesia were recorded at the end of the operation for 1 hour. If the level of shivering aggravates during the observation, continue to record the EMG value of the new level of shivering as described above. Results A total of 224 effective EMG values were recorded, of which 52 were corresponding to Wrench grade 0, and their median EMG values were 42 (40? 45) dB, 75 (50? 55) decibels for grade 2, 53 (50? 55) decibels for grade 2, and 53 (50? 55) decibels for grade 2, respectively. The third grade corresponds to 58, with a median of 60 (56 / 63) decibels, and the fourth grade corresponds to 39 (64 / 62) decibels with a median of 64 (62 / 66) decibels. There were statistically significant differences in EMG values between different levels of shivering (P0.01). There was a significant correlation between the level of shivering after general anesthesia and the size of EMG (r = 0.879, P0.01). Conclusion the level of Wrench shivering after spinal surgery under general anesthesia is correlated with EMG recorded by VISTA Bis monitor. It is possible to use VISTA Bis monitor to monitor the occurrence and development of shivering, which may be a new, continuous, objective and accurate quantitative shivering monitoring method.
