We investigated the cross-sectional area of the femoral vein and its relationship to the femoral artery at two anatomical levels, in infants and children. Sixty-six subjects were allocated to one of two groups: infants (< 1 year, n = 31) or children (1-6 years, n = 35). After induction of general anaesthesia, the femoral vein was evaluated by ultrasound with the patients' legs at 30° and 60° of abduction and their hips externally rotated. In each position, measurements were taken at the level of the inguinal crease and 1 cm below the crease. Hip rotation with 60° leg abduction decreased femoral artery overlap at the level of the inguinal crease in both infants (p = 0.013) and children (p = 0.003). Thus, the optimal place for femoral vein cannulation in paediatric patients seems to be at the level of the inguinal crease with 60° leg abduction and external hip rotation.
我们研究了在两个解剖学水平，婴儿和儿童的股静脉横截面积与其与股动脉的关系。66 名受试者被分为两组之一：婴儿（<1 岁，n=31）或儿童（1-6 岁，n=35）。在全身麻醉诱导后，将患者的腿部外展 30°和 60°，髋关节外旋，用超声评估股静脉。在每个位置，在腹股沟皱褶水平和皱褶下方 1 厘米处进行测量。髋关节旋转 60°，腿部外展减少了腹股沟皱褶水平处股动脉重叠，在婴儿（p=0.013）和儿童（p=0.003）中均如此。因此，在儿科患者中，股静脉置管的最佳位置似乎是在腹股沟皱褶水平，腿部外展 60°，髋关节外旋。
