【目的】为找到一种更适合新生儿疾病筛查的采血针,在较短时间内大幅度提高血片合格率。【方法】对刀片采血针1mm、刀片采血针2mm及普通三棱针三种不同的采血针采血所需时间、血斑直径大小、采血结束后压迫止血时间、采血次数等量化指标进行分析。【结果】刀片采血针采血所用时间明显少于普通三棱针,BD公司1mm采血针与BD公司2mm采血针采集血样标本时间接近;刀片采血针采集的血片质量明显高于普通三棱针,以BD公司2mm采血针效果最佳;BD公司2mm采血针采集标本结束后所需的压迫止血时间明显长于普通三棱针和BD公司1mm采血针;使用刀片采血针采血次数明显少于普通三棱针(P均<0.01)。【结论】刀片采血针可以提高血片采集质量,适合新生儿疾病筛查采血使用。
【Objective】 In order to find a lancing needle which is more suitable for neonatal screening, it can greatly improve the qualified rate of blood chip in a short time. 【Method】 The time required for lancet blood sampling, the diameter of blood spot, the time to stop bleeding after blood sampling, the number of blood sampling and other quantitative indexes were analyzed for 1mm lancet, 1mm lancet and 2mm lancet. 【Result】 The time of blood sampling for lancet needles was less than that of ordinary needles. The time taken by 1mm lancet between BD company and 2mm lancet of BD company was close to that of blood sample taken by blade lancet. BD 2mm lancet to the best effect; BD company 2mm lancet after the end of the required specimen compression hemostasis was significantly longer than the conventional three-edged needle and BD 1mm lancet; blade lancet blood sampling was significantly less than the average Needle (P <0.01). 【Conclusion】 The blade lancet can improve the quality of blood collection and is suitable for the neonatal screening.
