在围手术期，手指血流的评价将是有用的，在早期检测循环容量减少，体温调节反应或过敏样反应，并评估血管活性药物的影响。本研究旨在评估指尖温度、核心指尖温度梯度和指尖前臂温度梯度作为指尖血流指标在手术室临床环境中的可靠性。术中每隔5 min测一次鼻咽温度，同时用激光多普勒血流仪测定指尖皮肤表面血流。这些测量是在有IV导管（+IV组，n =11）或无IV导管（-IV组，n=11）的同一上肢进行的。指尖血流量，转化为对数尺度，显着相关的任何三个热措施在两组。在-IV组中，作为指尖血流指标的等级顺序为前臂-指尖温度梯度（r=-0.86）>指尖温度（r=0.83）>鼻咽-指尖温度梯度（r=-0.82），+IV组为鼻咽-指尖温度梯度（r=-0.77）>指尖温度（r=0.71）>前臂-指尖温度梯度（r=-0.66）。-IV组指尖血流量与各项体温指标的相关性较强（P
During the perioperative period, evaluation of digital blood flow would be useful in early detection of decreased circulating volume, thermoregulatory responses or anaphylactoid reactions, and assessment of the effects of vasoactive agents. This study was designed to assess the reliability of fingertip temperature, core-fingertip temperature gradients and fingertip-forean-n temperature gradients as indices of fingertip blood flow in the clinical setting of the operating theatre.In 22 adult patients undergoing abdominal surgery with general anaesthesia, fingertip skin-surface temperature, forearm skin-surface temperature, and nasopharyngeal temperature were measured every five minutes during the surgery.Fingertip skin-surface blood flow was simultaneously estimated using laser Doppler flowmetry. These measurements were made in the same upper limb with an IVcatheter (+IVgroup, n =11) or without an IVcatheter (-IV group, n=11). Fingertip blood flow, transformed to a logarithmic scale, significantly correlated with any of the three thermal measures in both the groups. Their rank order as an index of fingertip blood flow in the -IV group was forearm-fingertip temperature gradient (r=-0.86) > fingertip temperature (r=0.83) > nasopharyngeal-fingertip temperature gradient (r=-0.82), while that in the +IV group was nasopharyngeal-fingertip temperature gradient (r=-0.77) > fingertip temperature (r=0.71) > forearm-fingertip temperature gradient (r=-0.66). The relation of fingertip blood flow to each thermal measure in the -IV group was stronger (P
