摘要
目的探讨折叠输液管产生负压来提高小儿头皮静脉穿刺成功率的临床效果。方法将200例头皮静脉穿刺的患儿随机分成对照组和观察组各100例,对照组采取常规静脉穿刺法,观察组采取折叠输液管法,于排气后将输液管末端折叠0.5cm,用夹子夹紧,当针头刺入皮下后松开夹子,使输液管内产生少量负压。观察2组患儿头皮静脉穿刺时的自然回血情况及穿刺成功率。结果对照组自然回血率72%,穿刺成功率87%;观察组自然回血率97%,穿刺成功率97%。观察组自然回血率和穿刺成功率均高于对照组。结论折叠输液管法能迅速判断针头进入血管,可有效提高静脉穿刺成功率。
Objective To probe into the clinic effect of folded infusion tube which can produce negative pressure on increasing the success rate of infants' scalp venepuncture. Methods 200 infant patients were divided into the control group and the observation group with 100 cases in each group. The control group used routine venepuncture method, while folded infusion tubes are used in the observation group. The end of infusion tubes were folded by 0.5 cm and clamped well. When the needle has been punctured under an infant patient's scalp, the clamp could he loosed so that there was a little negative pressure in the tube. Then the situation of natural revehent blood and success rate of scalp venepuncture were observed in the two groups. Results Rate of natural revehent blood in the control group was 72%, and success rate of scalp venepuncture was 87%. Rate of natural revehent blood in the observation group was 97%, and success rate of scalp venepuncture was 97%. Rate of natural revehent blood and success rate of scalp venepuncture in the observation group were both higher than those of the control group. Conclusions Folded infusion tube can immediately judge whether the needle is punctured inside the blood vessel and effectively increase the success rate of scalp venepuncture.
