摘要
目的观察复方利多卡因乳膏在单采血小板静脉穿刺中的镇痛效果。方法将95例捐献血小板的献血者分为两组。A组为复方利多卡因乳膏作用30min,B组为复方利多卡因乳膏作用1h,同一献血者的右臂设为实验组,左臂为对照组(穿刺位置涂抹等量的护手霜)。按视觉模拟评分法(VAS)评估献血者静脉穿刺时的疼痛程度。结果 A组50例献血者中显效20例,中效18例,有效率为76.00%,实验组、对照组镇痛效果差异有显著性(χ2=28.83,P<0.01)。B组45例献血者中显效25例,中效13例,有效率为84.44%,实验组、对照组镇痛效果差异有显著性(χ2=24.51,P<0.01)。但A组与B组有效率比较差异无显著性(P>0.05)。结论复方利多卡因乳膏可减轻献血者单采血小板静脉穿刺时的疼痛感,可作为一种良好的镇痛剂,为了减少献血者的等待时间实际工作中选择作用30min即可。
Objective To assess the analgesic effect of compound lidocaine cream on venipuncture in blood-platelet collec- tion （BPC）. Methods Ninety-five blood donors wee divided into two groups as A and B. The cream was smeared on the location of puncture for 30 min in group A, and that in group B was kept for 60 min. The right arm was set for experimental and left arm for control in the same donor. According to visual analogue scale （VAS）, the extent of pain during venepuncture was recorded. Results In group A of 50 donors, 20 were significantly effective, and 18 effective, the effective rate being 76.00%, the effective- ness of pain relieving between the experimental and control groups was significant （X2 =28.83,P〈0.01）. In group B of 45 donors, excellence was recorded in 25, moderate effectiveness in 13, effective power being 84.44%, the difference between experimental and control groups was significant （x2=24.51, P〈0.01）. There was no statistical difference between groups A and B in terms of effective power （P〉0.05）. Conclusion Compound lidocaine cream can be used as a satisfactory analgesic agent to relieve pain at venipuncture procedure of blood collection. In order to reduce waiting time of the blood donors, the 30 min action manner of the cream may be selected in daily practice.
