本文报导了一种新的痛觉阈值测定法——二氧化碳激光痛觉阈值测定法。对278例使用各种镇静、镇痛、麻醉方法的实验动物在实验前后所测得的痛觉阈值进行对比分析和效果检验,结果证明本文中报导的方法有受干扰少,准确性高、离散程度小、适应性强、测定范围广、能客观反映痛觉阈值的特点。 This article reports a new method of pain threshold determination - the carbon dioxide laser pain threshold method. The analgesic thresholds of 278 experimental animals using various methods of sedation, analgesia and anesthesia were compared and tested before and after the experiment. The results showed that the methods reported in this paper were less disturbed, more accurate and more discrete Small, adaptable, wide range of measurement, can objectively reflect the characteristics of pain threshold.
