摘要
目的：观察１％盐酸丁卡因碱化凝胶减轻静脉穿刺疼痛的透皮局部麻醉效果。方法：６０例拟行静脉穿刺术的病人随机分成实验组和安慰组。每组３０例。将１％盐酸丁卡因碱化凝胶和安慰凝胶分别涂敷于患者手背皮肤，４５ｍｉｎ后行静脉穿刺术。采用４级口述分级法和视觉模拟评分法评估透皮局部麻醉效果。结果：１％盐酸丁卡因碱化凝胶可使疼痛分值较安慰凝胶显著下降（Ｐ＜０．０１），其减轻静脉穿刺疼痛作用明显优于安慰凝胶。结论：１％盐酸丁卡因碱化凝胶能为静脉穿刺提供较有效的透皮局部麻醉，具有一定的临床应用价值。
Objective.The percutanous local anesthesia effect of alkalized tetracaine hydrochloride gel on reducing the pain of venepuncture was observed: Methods:alkalized 1% tetracaine hydrochloride gel and placebo were applied to the dosum of hand respectively for a period of 45 min.After removal of the gels,venepuncture was performed.Patients assessed the pain experienced using four-point verbal rank score and visual analogue scale.Results:Statistical analysis of results indicated that there was singnificant difference in pain scores betwen two groups(P<001)and that alkalized 1% tetracaine hydochloride gel was superior to placebo.Conclusions:Alkalized 1%tetracaine hydrochlorid gel produced effctive percutanous anesthesia for venepuncture and was of clinical value.
