Femoral Nerve Block

Peripheral nerve blocks preclude the need for procedural sedation and provide adequate anesthesia during painful procedures. This technique can be performed in the emergency department with the aid of ultrasound imaging to identify target nerves. We describe eight cases of upper and lower extremity nerve blocks performed under ultrasound guidance in the emergency department of the Jai Prakash Narayan Trauma Centre, All India Institute of Medical Sciences, New Delhi. Only two of the patients, both with extensive injuries, required any additional anesthesia during the subsequent procedures and all of them reported significant pain control and muscle relaxation.

Before clinical treatment and during transportation, the analgesic therapy offered to patients with painful knee trauma may be quite insufficient. We hypothesize that a femoral nerve blockade for analgesia can be administered in a preclinical setting at the injury site and provides better pain relief than intravenous metamizole, whose analgesic effect is comparable with that of opioids. Patients with painful knee trauma benefited from femoral nerve blockade administered before hospitalization. The treatment can be administered safely in the preclinical setting and provides effective analgesia.


Femoral nerve blockade administered preclinically for pain relief in severe knee trauma is more feasible and effective than intravenous metamizole: a randomized controlled trial.
