目的探讨力学穿刺法在婴幼儿疑难头皮静脉留置针穿刺输液中的应用效果。方法采用临床随机对照研究,选取门诊输液患儿300例,随机分为观察组和对照组各150例。观察组用力学原理穿刺法,即通过调低调节器高度、降低输液瓶高度至与穿刺部位平齐,增加与静脉血管内压力差的力学原理进行穿刺;对照组用传统负压穿刺法。比较两组的留置针一次穿刺成功率、病人满意率和平均穿刺时间。结果力学穿刺法一次穿刺成功时间(6.1±0.51)min比负压穿刺法(7.3±0.56)min短,满意率(92.7%)比负压穿刺法(80.7%)高;一次穿刺成功率(89.3%)与负压穿刺法(94.0%)差异无统计学意义。结论力学穿刺法的穿刺时间较短,减少了患儿反复多次穿刺的痛苦,家属满意度较高,其操作简便,可单人操作,减少了护理人员人力资源浪费,提高了工作效率。
Objective To investigate the application of mechanical puncture in infants with difficult scalp vein indwelling needle puncture infusion. Methods A randomized controlled clinical trial was conducted in 300 infants with outpatient infusions and randomly divided into observation group (150 cases) and control group (150 cases). The observation group was punctured by the mechanical principle of puncture, that is, by lowering the height of the regulator, lowering the height of the infusion bottle to flush with the puncture site, and increasing the pressure difference with the venous blood vessel. The control group was punctured by the traditional negative pressure. The success rate of one puncture of the indwelling needle in two groups was compared, the patient satisfaction rate and average puncture time were compared. Results The successful puncture time of mechanical puncture was (6.1 ± 0.51) min shorter than that of negative puncture (7.3 ± 0.56) min, the satisfaction rate was 92.7% higher than negative pressure puncture (80.7%). The success rate of primary puncture %) And negative pressure puncture (94.0%) showed no significant difference. Conclusions The puncture time of mechanical puncture method is short, which reduces the pain of repeated puncture in children. The satisfaction of family members is higher. The operation is simple and can be operated by a single person, which reduces the waste of human resources and improves the working efficiency.
