Novel Use of 3-Point Genicular Nerve Block for Acute Knee Pain in the Emergency Department.
Ultrasound-guided genicular nerve blocks (GNBs) in the emergency department (ED) have easily identifiable anatomic targets and offer an opportunity to provide safe, effective, motor-sparing analgesia for acute knee pain. Case Report A 68-year-old woman presented with acute, 8/10 right knee pain due to an isolated right lateral tibial plateau fracture. After informed consent and with the ultrasound in the sagittal plane, the superior lateral (SLGN), superior medial (SMGN), and inferior medial (IMGN) genicular nerves were identified at the junction of their respective femoral or tibial epicondyle and femoral or tibial epiphysis. ⋯ She did not require opioids during her ED visit or upon discharge. Why Should an Emergency Physician Be Aware of This? GNBs show promise as a useful tool to provide acute and medium-term motor-sparing analgesia in a patient with acute knee pain. GNBs have easy-to-recognize anatomic targets on ultrasound and may be a suitable adjunct or alternative to a multimodal pain regimen in the emergency department.

Observational StudyLocating Adductor Canal and Quantifying the Median Effective Volume of Ropivacaine for Adductor Canal Block by Ultrasound.
To identify the precise position of adductor canal; and to determine median effective volume (EV50) for adductor canal block (ACB) by ultrasound. ⋯ The midpoint between the femoral trochanter and the superior margin of patella is in the adductor canal. EV50 of 0.5% ropivacaine for ACB is 10.79 ml (95% CI, 10.10-11.52 ml). Key Words: Adductor canal, Location, Ultrasound, Median effective volume, Nerve block.
