【摘要】 目的 比較上臂三角肌下緣及腹部臍周皮下注射藥物的疼痛程度以及兩種注射部位藥物注射后局部不良反應(yīng)。 方法 將2009年9月-2010年5月在我院門診注射室執(zhí)行皮下注射的患者200例。采用自身對(duì)照，分別在三角肌下緣與腹部臍周行皮下注射，根據(jù)視覺模擬評(píng)分法，對(duì)所有患者進(jìn)行疼痛程度評(píng)估，將所得數(shù)據(jù)進(jìn)行對(duì)比分析?！〗Y(jié)果 腹部臍周皮下注射較上臂三角肌下緣注射疼痛評(píng)分低，差異有統(tǒng)計(jì)學(xué)意義（Z=6.02，Plt;0.005），兩組注射局部均無不良反應(yīng)?！〗Y(jié)論 腹部臍周皮下注射疼痛程度較上臂三角肌下緣皮下注射疼痛程度輕。【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.
