摘要
目的探讨老人中位硬膜外阻滞初量的个体使用规律。方法≥65岁的中位硬膜外阻滞患者65例,依病人对药物的耐受程度分次注入初量,记录前3次(试验量、分量2、分量3)药量、阻滞平面,计算出相应时点阻滞范围内每个神经节段所需药量,进行相关分析。结果相邻时点前、后阻滞范围内每个神经节段所需药量存在有显著的线性正相关(P<0.01),相关方程依次为y=0.23+1.02x,y=1.61x-0.38。结论老人中位硬膜外阻滞初量的给予中,可依据前次给药时点产生阻滞范围内的每个神经节段所需药量用相关方程推算。
Objective To explore the initiative individual dose for middle epidural blockade in the aged. Methods Sixty-five patients （age≥65 years） were scheduled for middle epidural blockade anesthesia. The test doses and supplementary dose were estimated according to response of patients to the initiative dose. To record the drag dose and blockade segments of epidural blockade anesthesia, the dose each nerve section within the scope of block needed were calculated and analyzed. Results The dose each nerve section within the scope of block needed showed significant positively linear correlation （P〈 0.01 ） between each two adjoining time points. The equation of correlation was obtained in proper order y = 0.23 ＋ 1.02x, y =1.61x - 0.38. Conclusion Initiative dose of middle epidural blockade in the aged may be calculated with the equation of correlation according to the last dose.
