Pengaruh Eksorotasi Tungkai Bawah terhadap Jarak Saraf Femoralis dan Arteri Femoralis: Observasi dengan Panduan Ultrasonografi

The Effect of Lower Extremity Exorotation on the Distance Between the Femoral Nerve and the Femoral Artery an Observational Study Using Ultrasound Guidance Femoral nerve block with nerve stimulation guidance technique is a common technique in Indonesia. Malayan race has a different landmark anatomy used in femoral nerve block with Caucasian and Mongoloid races, thus Malayan race has a different femoral nerve-femoral artery distance from other races. This study observed the effect of lower extremity exorotation on the femoral nerve-the femoral artery Malayan race. A cross-sectional study on 30 elective surgery patients in Cipto Mangunkusumo Hospital was done in February 2016. Two-dimensional ultrasonographic images of the femoral nerve were obtained by ultrasound guidance in the inguinal crease in four positions of the bilateral lower extremities: 0°, 15°, 30°and 45° exorotation of each extremity. Nerve to artery There were significant differences of the femoral nerve-femoral artery distance at all exorotation angles (0o, 15o, 30o and 45o) in both feet (p<0.001). There was no significant difference of femoral nerve-femoral artery distance between the right foot and the left foot in all measurements. There was no significant difference of femoral nerve-skin distance at all exorotation angles.In Malayan race, the greater the degrees of lower extremity exorotation resulted in the greater distance of the femoral nerve to the femoral artery.
