Fascia iliaca blocks (FIC, FICB) is a local anesthetic nerve block, a type of local anesthesia, used for the hip and thigh. FIC can performed by using ultrasound or with a loss of resistance technique, the latter sometimes referred to as the "two-pop-method". FIC works by affecting the femoral, obturator and the lateral cutaneous nerves with a local anesthetic.

Technique

When FIC is performed with the loss of resistance technique, the injection site for FIC is found by drawing an imaginary line between the pubic tubercle to the anterior superior iliac spine. The injection site is 1 cm. below the lateral one third and the medial two thirds of this line. Two losses of resistances are felt as the fascia lata and the fascia iliaca is penetrated by a semi-blunt cannula. Aspiration (drawing back the cannula) is performed, after which a local analgesic is injected while compressing on the skin distally to increase cranial distribution.

History

The block was first described in 1989 as an alternative to 3-in-1 nerve block in children.^[1]
