Ultrasound-guided nerve blocks in the emergency department.

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.
