1、对静脉穿刺进针角度的研究摘要目的:在实习过程中发现在进行静脉穿刺时,不同的进针角度病人的疼痛感也不一样。通过对静脉穿刺进针角度的研究,认为静脉穿刺进针角度以进针时与皮肤成45°~60°角为宜,既不影响穿刺成功率,又可使病人疼痛感明显减轻。方法:选择住院接受静脉输液意识清晰、能正确表达、准确配合的患者280例,随机分为观察组和对照组,其中男156例,女124例,年龄在20~68岁。实验组及对照组均由作者本人操作,观察组静脉穿刺与皮肤成45°~60°角进针穿过皮肤,对照组以除针头与皮肤成15°~30°角进针,除进针角度不同之外,其余操作实验组与对照组都相同。结果:观察组静脉穿刺与皮肤成45°~
2、60°角进针,病人疼痛反应轻,其中微痛98例次,一般疼痛30例次,剧痛12例次。微痛率占70%。对照组以与皮肤成15°~30°角进针,疼痛反应明显,其中微痛44例次,一般疼痛62例次,剧痛34例次.其无痛率占31.43%.无痛与一般疼痛之间X2=42.19,P<0.01,存在显著性差异,观察组的穿刺成功率为96.4%,对照组是92.1%。患者通过简式McGill疼痛量表所打分值,在0~~13分的观察组为96人,对照组为40人。11~23分的观察组为30人,对照组为68人,24~~37分观察组为14人,对照组32人。结论:实验表明,静脉穿刺进针角度以进针时与皮肤成45°~60°角时病人的疼痛
