The relation of the forehead-sole deep body temperature difference with the cardiac index (CI), and the relation of that with the systemic vascular resistance index (SVRI) were studied in 61 adult patients after open-heart surgery for 24 hours. A correlation between the deep body temperature difference (X) and CI (Y) was expressed as, Y = -0.21X + 3.42 (r = 0.48), and that between the deep body temperature difference (X) and SVRI (Y), Y = 184X + 808 (r = 0.52). But immediately after the end of operation (n = 61), the correlation coefficients (r) were lower, 0.46 and 0.45, respectively. The deep body temperature difference was 1.8 degrees C on the average in patients whose CI was 2.21.min-1.m-2, and was 4.3 degrees C in patients whose CI was below 2.21.min-1.m-2. Conversely CI was below 2.21.min-1.m-2 in patients whose deep body temperature difference was more than 4 degrees C. We conclude that the measurement of deep body temperature difference is useful as a circulatory monitor, and that a critical level of deep body temperature difference is 4 degrees C.
对61例成人心脏直视手术后24小时的患者，研究了前额 - 足底深部体温差与心脏指数（CI）的关系以及与全身血管阻力指数（SVRI）的关系。深部体温差（X）与CI（Y）之间的相关性表示为Y = -0.21X + 3.42（r = 0.48），深部体温差（X）与SVRI（Y）之间的相关性为Y = 184X + 808（r = 0.52）。但在手术结束后即刻（n = 61），相关系数（r）较低，分别为0.46和0.45。CI为2.21.min-1.m-2的患者深部体温差平均为1.8℃，CI低于2.21.min-1.m-2的患者深部体温差为4.3℃。相反，深部体温差超过4℃的患者CI低于2.21.min-1.m-2。我们得出结论，深部体温差的测量作为循环监测指标是有用的，深部体温差的临界水平为4℃。
