摘要: 应用一种自制并加以改进的压脚痛阈测定法,观察大鼠足部注射芬太尼对压脚痛阈的影响。结果表明,局部注射芬太尼对致炎大鼠的痛敏有显著的抑制作用;对正常大鼠的压脚痛阈没有明显影响。结果提示,在炎症痛存在的条件下,芬太尼具有外周镇痛作用;但在正常大鼠,芬太尼不参与外周镇痛。

Abstract: The effect of fentanyl injected into rat paw on paw-pressure threshold was observed with a self-made and improved paw-pressure technique in the present paper. The results from the peripheral analgesic study show that local inj- ction of fentanyl into rat paw produces significant inhibition of inflamm- atory hyperalgesia but has no effect on normal paw. The results suggest that peripheral analgesic effect of fentanyl occurs under conditions of inflammation and accompanying pain but not on normal rats.
