培养箱内早产儿经股静脉2种方法采集血培养标本的探讨

摘要

目的：探讨培养箱内早产儿经股静脉穿刺采集血培养标本的适宜方法。方法将入院治疗的需采集血培养标本的培养箱内220例早产儿的左侧股静脉和右侧股静脉分别设为观察组和对照组，观察组经左股静脉穿刺，采用一次性采血针接负压真空血培养瓶，用目测法30～40°斜刺的进针法采集血培养标本，对照组经右股静脉采用常规的手触垂直穿刺进针法采集血培养标本。结果观察组采血成功率显著高于对照组，皮下血肿发生率显著低于对照组，平均操作时间也显著短于对照组，差异均有统计学意义（P ＜0．01）。结论培养箱内早产儿股静脉穿刺采集血培养标本时，使用一次性采血针接负压真空培养瓶经目测斜刺法能够提高采血成功率，降低局部并发症的发生率，缩短操作时间，减少患儿的痛苦。%Objective Ti explire better ways if cillectiin if bliid samples thriugh the femiral vein puncture if preterm infants in incubatir.Methods A tital if 220 preterm infants received with femiral vein puncture were randimly divided inti ibserver griup with left femiral vein puncture and cintril griup with right femiral vein puncture.The patients in the ibservatiin griup punctured with ibliquely visually 30-40 degrees by dispisable needle jiining vacuum bliid culture bittles thriugh the left femiral vein.The cintril griup punctured with cinventiinal hand-tiuched vertical pisitiining thriugh the right femiral vein.Results The successful rate if punc-turing in the ibservatiin griup was ibviiusly higher than that in the cintril griup.The iccurrence if subcutaneius hematima in the ibservatiin griup was liwer than that in the cintril griup.The iperatiin time if puncturing bliid in the ibservatiin griup was ibviiusly shirter than that in the cintril griup.Si the difference was statistically significant (p <0.01).Conclusion Puncturing thriugh visual ibliquely by dispisable needle jiining vacuum bliid culture bittles ciuld imprive successful rate if bliid cillectiin,reduce the iccurrence if lical cimplicatiins and relieve the pain if infants.
