不同进针角度对小儿头皮静脉留置针穿刺效果对比

目的:比较不同进针角度对小儿头皮静脉留置针穿刺效果。方法:选取93例头皮静脉留置针患儿作为研究对象,按照患儿就诊顺序依次纳入对照组、研究组1、研究组2各31例,并依次采取传统20°进针、改进的30°进针和45°进针方式穿刺。比较3组穿刺成功率。结果:研究组1患儿的一次性穿刺成功率为96.77%,研究组2为93.55%,对照组为74.19%,研究组1、研究组2成功率均高于对照组,差异有统计学意义(P<0.05);研究组1与研究组2穿刺一次成功率比较,差异无统计学意义(P>0.05);研究组1、研究组2的静脉留置针的留置时间均长于对照组,差异有统计学意义(P<0.05);研究组1和研究组2静脉留置针的留置时间比较,差异无统计学意义(P>0.05);研究组1、研究组2患儿家长护理满意度均高于对照组,差异有统计学意义(P<0.05);研究组1和研究组2患儿家长护理满意度比较,差异无统计学意义(P>0.05)。结论:30°和45°进针的方式优于传统20°进针,提高了穿刺成功率,减轻了患儿疼痛,满意度明显提高。

Comparison of puncture effects of different puncture angles of scalp vein indwelling needle in children

Objective:To compare puncture effects of different puncture angles of scalp vein indwelling needle in children.Methods:Ninety-three children with scalp vein indwelling needles were selected as the subjects.According to the order of visiting,they were divided into control group,study group 1 and study group 2,31 cases in each group.Traditional 20°needle insertion,improved 30°needle insertion and 45°needle insertion were adopted,orderly.The success rate of puncture was compared among the three groups.Results:The success rate of one-time puncture was 96.77%in study group 1,93.55%in study group 2 and 74.19%in control group.The success rates of study group 1 and study group 2 were higher than that of control group(P<0.05),and the differences were statistically significant(P<0.05);however,there was no significant difference between study group 1 and study group 2(P>0.05).The indwelling time of intravenous indwelling needle in study group 1 and 2 were longer than that in control group,and the differences were statistically significant(P<0.05);however,there was no significant difference between study group 1 and study group 2 in the indwelling time of intravenous indwelling needle(P>0.05).The nursing satisfactions of the parents in study group 1 and 2 were higher than that in control group,and the differences were statistically significant(P<0.05);however,there was no significant difference between study group 1 and study group 2(P>0.05).Conclusions:30°needle insertion and 45°needle insertion are superior to the traditional 20°needle insertion,which can improve the puncture success rate,relieve the children’pain,and significantly improve the satisfaction.
