The collateral circulation to the hand was evaluated on 70 hands of healthy volunteers. Comparisons were made between the results of the modified Allen's test alone and the Allen's test combined with either plethysmography or digital blood pressure. The modified Allen's test requires patient cooperation and the results can be subjective. Plethysmography does not require patient cooperation and produces a signal that varies directly with flow; however, this is not a quantifiable signal. Digital blood pressure (measured by the 2300 Finapres noninvasive blood pressure monitor, Ohmeda, Englewood, CO, USA) also requires no patient cooperation. The values produced are of clinical value and reproducible. Both the plethysmograph and digital blood pressure monitors were able to demonstrate the dominant arterial vessel of the hand. The digital blood pressure monitor produces an objective recordable numerical value, an accepted clinical parameter, and it does not require patient cooperation. The use of a digital blood pressure monitor may prove to be an acceptable alternative to the traditional Allen's test.
对70名健康志愿者的手部侧支循环进行了评估。对单纯改良艾伦试验的结果与改良艾伦试验结合体积描记法或指端血压测量的结果进行了比较。改良艾伦试验需要患者配合，结果可能主观。体积描记法不需要患者配合，产生的信号与血流量直接相关；然而，这不是一个可量化的信号。指端血压（由美国科罗拉多州恩格尔伍德市欧姆达公司生产的2300型Finapres无创血压监测仪测量）也不需要患者配合。所产生的值具有临床价值且可重复。体积描记仪和指端血压监测仪都能够显示手部的主要动脉血管。指端血压监测仪产生一个客观的、可记录的数值，这是一个公认的临床参数，并且不需要患者配合。使用指端血压监测仪可能被证明是传统艾伦试验的一个可接受的替代方法。
