Fascia iliaca block, supra-inguinal: go above the ligament for better spread

Question 1Which probe orientation does the supra-inguinal approach use?

1. aTransverse over the pubic symphysis
2. bSagittal, medial to the anterior superior iliac spine, above the inguinal ligament
3. cParasagittal over the lumbar spine
4. dTransverse, below the inguinal ligament over the femoral artery

Question 2What advantage does the supra-inguinal approach have over the infra-inguinal approach?

1. aMore consistent spread to the lateral femoral cutaneous nerve
2. bIt blocks the sciatic nerve
3. cIt needs no ultrasound
4. dIt uses a much smaller volume

Question 3Which vessel helps confirm the plane in the supra-inguinal view?

1. aThe deep circumflex iliac artery
2. bThe femoral vein
3. cThe inferior epigastric vein below the umbilicus
4. dThe popliteal artery

Question 4How does correct spread appear?

1. aA round swelling within iliacus
2. bFluid among the abdominal wall muscles
3. cA long strip of fluid under fascia iliaca running towards the head
4. dFluid in the fat over sartorius

Question 5Why does this block still need a dose calculation, even though the needle stays away from nerves?

1. aIt uses 30 to 40 mL, which brings the dose close to the maximum for many patients
2. bThe needle enters the femoral artery
3. cIt needs adrenaline in every case
4. dIt blocks both legs
