摘　　要：为估计全麻对体温及温度调节反应的影响，应用食管温度监测和前臂－指尖温差级数方法对４０例ＡＳＡⅠ～Ⅱ静脉普鲁卡因－芬太尼麻醉的胃癌根治术病人进行研究。麻醉诱导前平均食管温度为３６．５２±０．１６℃，前臂－指尖温差为１．２１±０．３２℃。诱导后４５ｍｉｎ，食管温度降低为３５．８１±０．３８℃，９０ｍｉｎ后降为最低值３５．５５±０．３２℃，并形成低温稳定期，手术结束时食管温度可达３６．１７±０．３８℃（与诱导前相比Ｐ＞０．０５）。前臂－指尖温差自麻醉诱导后４５ｍｉｎ始≥４℃，随着食管温度降低此差值逐渐增大，术中最高可达１０．５℃。此差值的增加主要由于指尖温度下降所致。手术结束时此值仍维持在８．２±０．１℃。结论：全麻病人术中存在活跃的温度代偿反应，通过外周血管收缩可有效的减少热量弯失和防止体温进一步下降。sophageaI temperature and skin-surface temperature gradients (forearm-fingertip temperature)as an indexof cutaneous vasconstriction were measured in patients under intrvenous anesthesia of procaine-fantornyl undergoing radical operation of gastric cancer. Before induction, average esophageal temperature was 36. 52 ± 0. 16℃,skin-surface temperature gradient was 1.21 ± 0.32 ℃, Esophageal temperature decreased to 35. 81 ± 0. 38 ℃ at45min after induction,and reached to a lowest and stable point of 35. 55±0. 32 ℃ at 90min after induction,By theend of Operation, esophogeal temperature was 36.17±0.38.Skin-surface temperature gradient was≥4 ℃ at 45minafter induction,the highest point of that was 10.5 ℃ during operation, The increased skin-surface temperatare gra-dient resulted primarily from a decreasecl fingertip temperature. It is concluded that by vasoconstriction an activethermoregulation occrs during general anesthesia, which effectiently decreases heat loss and prevents further hy-pothermia.
