Abstract

The relationships of the forehead-sole deep body temperature difference with the cardiac index (CI), and with the systemic vascular resistance index (SVRI) were studied in 10 pediatric patients (TOF 5, ASD 3, VSD 2) for 24 hours after open-heart surgery. A correlation between the deep body temperature difference (X) and CI (Y) was expressed as, Y = -0.49X + 4.51 (r = 0.72), and that between the deep body temperature difference (X) and SVRI (Z) as Z = 152X + 1039 (r = 0.62). The deep body temperature difference was 1.0 degrees C on the average in patients whose CI was more than 3.0 l.min-1.m-2, and was 3.3 degrees C in patients whose CI was less than 3.0 l.min-1.m-2. Conversely CI was less than 3.0 l.min-1.m-2 in patients whose deep body temperature difference was more than 3.0 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 3 degrees C in children.

摘要

对10例儿科患者（法洛四联症5例、房间隔缺损3例、室间隔缺损2例）心脏直视手术后24小时内的额-足底深部体温差与心脏指数（CI）及全身血管阻力指数（SVRI）的关系进行了研究。深部体温差（X）与CI（Y）之间的相关性表示为Y = -0.49X + 4.51（r = 0.72），深部体温差（X）与SVRI（Z）之间的相关性表示为Z = 152X + 1039（r = 0.62）。CI大于3.0 l·min⁻¹·m⁻²的患者，深部体温差平均为1.0℃；CI小于3.0 l·min⁻¹·m⁻²的患者，深部体温差为3.3℃。相反，深部体温差大于3.0℃的患者，CI小于3.0 l·min⁻¹·m⁻²。我们得出结论，深部体温差的测量作为一种循环监测指标是有用的，儿童深部体温差的临界值为3℃。
