A femoral nerve block is a nerve block that uses local anesthetic to achieve analgesia in the leg.The block works by affecting the femoral nerve.. A femoral nerve block (FNB) results in anesthesia of the skin and muscles of the anterior thigh and most of the femur and knee joint, as well as the skin on the medial aspect of the leg below the knee joint.
The infraorbital nerve is a branch of the maxillary nerve (itself a branch of the trigeminal nerve (CN V)). [1] It arises in the pterygopalatine fossa . It passes through the inferior orbital fissure to enter the orbit. [ 2 ]
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
The clinically important structures surrounding the orbit include the optic nerve at the apex of the orbit as well as the superior orbital fissure which contains cranial nerves 3, 4, and 6 therefore controlling ocular muscles of eye movement. [15] Inferior to the orbit is the infraorbital nerve which is purely sensory.
The infraorbital groove (or sulcus) is located in the middle of the posterior part of the orbital surface of the maxilla. Its function is to act as the passage of the infraorbital artery , the infraorbital vein , and the infraorbital nerve .
The infraorbital foramen contains the second division of the trigeminal nerve, the infraorbital nerve or V2, and sits on the anterior wall of the maxillary sinus. Both foramina are crucial as potential pathways for cancer and infections of the orbit to spread into the brain or other deep facial structures.

Protocols vary depending on local standard procedures and the extremity being operated on. A vast majority of practitioners begin by exsanguinating the limb as Bier did with an elastic bandage (Esmarch bandage), squeezing blood proximally toward the heart, then pneumatic tourniquets are applied to the limb and inflated 30mmHg above arterial pressure to occlude all blood vessels and then the ...
