离心性静脉穿刺采血与常规静脉穿刺采血的临床应用比较

Clinical application comparison of blood collection by centrifugal venipuncture and conventional venipuncture

目的探讨离心性静脉穿刺采血与常规静脉穿刺采血的临床应用价值。方法将于我站进行静脉采血者140例纳入研究,分为观察组及对照组,各70例。对照组使用常规静脉穿刺方法进行采血,观察组使用离心性静脉穿刺方法进行采血。对两组采血效果进行比较,同时对可能影响采血时间的因素进行分析。结果观察组被采血者一次穿刺成功率、即刻回血率均显著高于对照组(P<0.05)。观察组被采血者平均采血时间显著短于对照组(P<0.05)。对于采血量为2 m L的被采血者而言,观察组与对照组采血时间无显著差异(P>0.05);对于采血量为4 m L及6 m L的被采血者而言,观察组采血时间明显短于对照组(P<0.05)。对于静脉条件好的被采血者而言,观察组与对照组采血时间无显著差异(P>0.05);对于静脉条件中或差的被采血者而言,观察组采血时间明显短于对照组(P<0.05)。结论与常规静脉穿刺采血比较,离心性静脉穿刺在采血量较大及血管状态不佳时具有更快的采血速度,对于高效采血及保护血管具有积极意义,值得在临床进行推广。

Objective To explore the clinical application value of blood collection by centrifugal venipuncture and conventional venipuncture. Methods One hundred and forty people who received intravenous blood samples were included in the study and were divided into observation group and control group, with 70 people in each group. The control group underwent conventional venipuncture, and the observation group underwent centrifugal venipuncture. The effects of blood collection in the two groups were compared, and the factors that affect the blood collection time were investigated. Results The one-time success rate of venipuncture and the blood immediately return rate blood of the observation group were significantly higher than those of the control group （P〈0.05）. The blood collection time of the observation group was significantly shorter than that of the control group （P〈0.05）. For people with a blood collection of 2 mL, the blood collection time of the two groups had no statistical significance （P〉0.05）, for people with a blood collection of 4 mL and 6 mL, the blood collection time of observation group were significantly shorter than those of the control group （P〈0.05）. For people who had good venous condition, the blood collection time of the two groups had no statistical difference （P〉0.05）; for people who had a medium and bad venous condition, the blood collection time of the observation group were significantly shorter than those of the control group （P〈0.05）. Conclusion Centrifugal venipuncture has better velocity of blood collection for people have large volume or bad vein condition, which has positive significance for the efficient blood collection and protection of blood vessels. It is worthy of clinical application.
