FEMORAL NERVE BLOCK

Position:Supine

Site of Needle Entry:A point 2 cms below the inguinal ligament and 1cm lateral to the femoral artery.

Technique:A 4cm needle is entered at the above point perpendicular to the skin to pierce the iliopectineal fascia and fascia lata and parasthesia is elicited. If nerve locator is used the motor response depends on division of the femoral nerve that is stimulated. If the anterior division is stimulated the vasti respond. It is always better to have a motor response of the posterior division for a complete block especially if surgery is around the knee joint.

After the first injection of the drug the needle is removed and again entered into the skin from a site 1 cm lateral to the previous point and the needle is directed to lie below the femoral artery. About 8 ml of drug is injected here. This ensures the posterior division is always blocked.

Volume: 20ml

Pearls:

	In 20% of individuals the nerve divides above the inguinal ligament. In such circumstances separate block of the posterior division is very vital
	Continous catheter can be placed here
	Very useful for acute pain relief in femur fractures.
