两种小儿静脉留置针穿刺方法的效果观察

目的探讨两种小儿静脉留置针穿刺方法的效果。方法按静脉留置针穿刺先后次序将60例患儿分为传统组和改进组,每组各30例。传统组在静脉留置针穿刺到血管后采用双手配合送管方法,改进组在静脉留置针穿刺到血管后采用单手推管并及时将回血冲净方法。结果传统组穿刺成功率60.00%,改进组穿刺成功率90.00%;传统组留置时间为（3.06±0.90）d,改进组为（4.56±0.93）d,两组比较,均P〈0.01,差异具有统计学意义。结论在静脉留置针到达血管后采用单手推管法并及时将回血冲净,可提高小儿头皮静脉穿刺成功率和静脉留置针留置时间。

Clinical observation of two puncturation methods for indwelling intravenous needle in infants

Objective To study the effects of two puncturation methods for indwelling intravenous needle in infants.Methods Sixty infants were equally assigned into the control group and the experiment group.In the former group,after the needles punctured into blood vessels,the cannulas was sent with two hands and in the latter,the catheters were indwelled in the veins with a single hand after rinsing the blood.Results The success rate of puncturation was 90.0% in the experiment group,Which was significantly higher than the rate of 60.0% in the control group（P 0.01）.The time for indwelling cannula was（4.56±0.93）d,Which was in significantly longer than that of（3.06±0.90）d in the control group（P 0.01）.Conclusion The method of pushing the cannula with a single hand after puncturing the blood vessels and rinsing the refluxing blood in the cannula may be effective in improving the puncturation success rate of infant scalp veins and extend the indwelling time for intravenous indwelling cannula.
