Introduction: Central venous catheterization is normally performed in the superior vena cava system; however, the femoral vein is an option in cardiorespiratory resuscitation and compression or thrombosis of the superior vena cava system. Knowledge of the anatomy of the femoral vein will allow for a safer puncture. Objective: to compare the femoral vein morphometry parameters of children, in the supine position and the position with external rotation, hip flexion, abduction, and thigh flexion (frog position). Materials and Methods: Cross-sectional observational study using ultrasound to analyze the morphometry of the femoral vein in the supine and frog position. Patients in the radiology sector of the pediatric hospital who would undergo ultrasound were included and consented to participate in the study. Results: Ninety-one patients were included with a mean age of 9.6 years. The cross-sectional area of the femoral vein was 47.6 cm2 on the left side and 42.2 cm2 on the right. This area increased to 79.9 on the left side and 74.6 on the right (p<0.01) in the frog position. The mean distance from the femoral vein to the skin was 15 mm on the left side and 14 mm on the right. In frogs, this distance decreased to 13 and 12, respectively, (p<0.01). Conclusion: The frog position allows for a larger sectional area, and less depth of the femoral vein, thus facilitating the puncture of the femoral vein.
