Fascia iliaca block

The patient is placed in a supine position. A line is drawn between the ASIS and pubic tubercle and divided into thirds. At the border between the lateral and medial thirds, a perpendicular line 2 cm in length is drawn caudally. A blunt needle is inserted and directed cephalad. Local anesthetic is injected when the operator appreciates two distinct "pops," first through the fascia lata and then through fascia iliaca. Utrasound is commonly used to aid with the approach.
