红外线热成像用于判断硬膜外麻醉痛觉平面变化的临床研究

Clinical study of infrared thermography in judging the change of pain level in epidural anesthesia

目的:探讨红外线热成像用于判断硬膜外麻醉痛觉平面变化的临床效果。方法:选取180例行硬膜外麻醉患者,采用红外线热成像技术采集硬膜外麻醉前后红外热像图,定性及定量分析热图温度变化。结果:针刺法测定麻醉后10min、15min、25min、45min、60min阻滞平面均高于麻醉后5min(P<0.05),麻醉25min时针刺阻滞平面最高。红外线热成像测定麻醉后各个时点的平均温度均高于麻醉前(P<0.05);麻醉后5min、10min、15min的平均温度间差异无统计学意义(P>0.05);麻醉后25min、45min、60min的平均温度均高于麻醉后5min(P<0.05)。结论:红外线热成像用于判断硬膜外麻醉痛觉平面变化具有无创、无痛、安全、直观及快速的优点。

Objective:To explore the clinical effect of infrared thermography in judging the change of pain level in epidural anesthesia.Methods:180 patients with epidural anesthesia were enrolled,and infrared thermography was used to collect infrared thermography before and after epidural anesthesia.The temperature of the heat map was qualitatively and quantitatively analyzed.Results:Acupuncture test showed that the blocking levels of 10,15,25,45 and 60 minutes after anesthesia were significantly higher than those of 5 minutes after anesthesia(P<0.05).The blocking levels of 25 minutes after anesthesia were the highest.The average temperature at each time point after anesthesia was higher than that before anesthesia by infrared thermography(P<0.05).There was no significant difference between the mean temperature at 5 min,10 min and 15 min after anesthesia(P>0.05).After anesthesia the average temperature at 25 min,45 min,and 60 min was higher than that at 5 min after anesthesia(P<0.05).Conclusion:Infrared thermography is used to judge the pain level of epidural anesthesia with the advantages of being non-invasive,painless,safe,intuitive and rapid.
