【摘要】 目的 比较上臂三角肌下缘及腹部脐周皮下注射药物的疼痛程度以及两种注射部位药物注射后局部不良反应。 方法 将2009年9月-2010年5月在我院门诊注射室执行皮下注射的患者200例。采用自身对照，分别在三角肌下缘与腹部脐周行皮下注射，根据视觉模拟评分法，对所有患者进行疼痛程度评估，将所得数据进行对比分析。 结果 腹部脐周皮下注射较上臂三角肌下缘注射疼痛评分低，差异有统计学意义（Z=6.02，Plt;0.005），两组注射局部均无不良反应。 结论 腹部脐周皮下注射疼痛程度较上臂三角肌下缘皮下注射疼痛程度轻。
【Abstract】 Objective To compare the difference in pain degrees between subcutaneous injection at the lower edge of upper arm deltoid and at the abdominal peri-umbilicus, and to observe the adverse reactions of the two ways of injection. Methods A total of 200 patients who were in the outpatient injection room from September 2009 to May 2010 were injected subcutaneously at the lower edge of upper arm deltoid and the abdominal peri-umbilicus with the method of self control; the pain degrees were assessed by visual analog score and the data were analyzed. Results The pain scores between the two groups differed much (Z=6.02,Plt;0.005), while the difference in space distributions between the two groups was not significant. Conclusion The pain of subcutaneous injection at the abdominal peri-umbilicus is lighter than that at the lower edge of upper arm deltoid.
