Details and patient eligibility

About

Patients were randomly assigned to tow groups: infrainguinal ultrasound guided iliaca fascia block (FIBSI) and femoral nerve block (FNB) for FIBSI, the probe is placed transversely between anterior superior iliac spine (ASIS) and the pubic spine. The transducer is translated laterally to identify the Sartorius muscle. Cephalic inclination of the probe. The medial end of the transducer faces towards the umbilicus, which is the final position. The 100mm neurostimulation needle is advanced in the In Plan approach to pass through the iliac fascia. Once the correct position is confirmed, 30 ml of 1% Ropivacaine is gradually injected between the iliac fascia and the iliac muscle.

For FNB, the probe was placed under the inguinal ligament. The femoral vessels and the nerve section are visualized; The 100mm neurostimulation needle is advanced in the In Plan approach and 30ml of 1% Ropivacaine has been injected along the nerve sheath

Full description

Patients were randomly assigned to tow groups: infrainguinal ultrasound guided iliaca fascia block (FIBSI) and femoral nerve block (FNB) for FIBSI,the probe is placed transversely between the EIAS and the pubic spine,The transducer is translated laterally to identify the sartorius muscle. Cephalic inclination of the probe: The iliac muscle is located at the medial border in the shadow of the superior anterior iliac spine.The medial end of the transducer faces towards the umbilicus, which is the final position.

The anatomy identified, from superficial to deep, consisting of subcutaneous fat, internal oblique muscle, transverse abdominal muscle, iliaca fascia covering the iliac muscle. The 100mm neurostimulation needle is advanced in In Plan approach to cross the iliaca fascia. With the tip of the needle just below the iliaca fascia, 2 ml of local anesthetic was injected to confirm the location of the tip. Once the correct position is confirmed, 30 ml of 1% Ropivacaine is gradually injected between the iliac fascia and the iliac muscle.

for FNB,The probe was placed under the inguinal ligament. Femoral vessels and sectional nerve are visualized. The nerve was located, an 100mm neurostimulation needle is advanced in In Plan approach, and 30 ml of 1% Ropivacaine was injected along the nerve sheath.
