新生儿解剖生理具特殊性,易受脱水等影响,使股动脉搏动触不清。故用寻摸股动脉搏动而推测股静脉位置的股穿方法,易造成判断和穿刺失误。为解决此难点,通过15例新生儿股静脉的尸体局部解剖,7例尸解后股静脉造影,探讨了以耻骨联合中点,髂前上棘及股骨内髁为骨性体表标志,直接判断新生儿股静脉的穿刺点和穿刺方法。又经37例临床验证,一针成功率达91.9％,报道如下。 Neonatal anatomy and physiology with particularity, susceptible to dehydration and other effects, so that the pulse of the femoral artery touch. Therefore, with the femoral artery pulse and speculate femoral vein position of the stock wear method, easy to make judgments and puncture errors. In order to solve this problem, 15 cases of neonatal femoral vein local autopsy, 7 cases of post-mortem femoral vein angiography, to explore the pubic symphysis midpoint, anterior superior iliac spine and femoral condyle as the body surface markers, direct To determine the neonatal femoral vein puncture and puncture methods. Another 37 cases of clinical validation, a needle success rate of 91.9%, reported as follows.
