老年人中位硬膜外阻滞初量个体化方程的应用

Application of the equation for the initiative individual dose of middle epidural blockade in elderly patients

目的验证老年人中位硬膜外阻滞初量个体化方程。方法≥65岁的中位硬膜外阻滞患者61例,在初量中的试验量后用药量依据前次阻滞每个神经节段需药量(DA/N)的相关方程计算得到,对比其相对应时点的预计与实际值,进行统计分析。结果初量的给药次数在2次以内为58/61例。用药量、阻滞神经节段数及DA/N的预计与实际值在第2时点一致(P>0.05)。结论利用相关方程实现老年人中位硬膜外阻滞初量个体化是可行的。

Objective To validate the equation for the initiative individual dose of middle epidural blockade in elderly patients. Methods 61 patients （age ≥65 ） were scheduled for anesthesia by middle epidural blockade. After the test doses of initiative dose, the fractionation dose was calculated with the equation of correlation for the dose per nerve section （DA/N） to the last dose. The expected data and the measurements were compared and statistically analyzed. Results The initiative dose were given less than twice （58/61）. The administered dose, the blockade segment and the DA/N of expected data coincided with the measurements at the second time point （P 〉 0.05 ）. Conclusion It＇s feasible to use the equation of correlation for the initiative individual close in middle epidural blockade in elderly patients.
