This study aims to determine if there is any difference in the success rate of ultra-sound
guided femoral nerve block performed with an echogenic needle versus a standard needle.
guided femoral nerve block performed with an echogenic needle versus a standard needle.
To date, the published information regarding ultrasound guided femoral nerve blocks (FNB)
using echo friendly needle is very limited. More so, there is even less information regarding
ultrasound guided nerve blocks using echogenic versus standard of care needles.
This study hopes to add to the general knowledge of pain management in the emergency
department (ED) setting and provide a unique perspective on ultrasound-guided techniques
using echogenic needles to enhance accuracy and success rate of nerve blocks in ED patients.
The study design will have two comparative arms; in both arms we use the same local
anesthetic which is Bupivacaine 0.25% with epinephrine; in all cases a total of 15 mL will be
injected around the femoral nerve. Once identified with ultrasound, 5 ml will be injected at
lateral, medial, and posterior aspect of the nerve. The experimental arm will receive an FNB
using an echogenic needle; and the control group will receive an FNB using standard of care
needles.
