Randomized Controlled TrialSingle-injection nerve blocks for total knee arthroplasty: femoral nerve block versus femoral triangle block versus adductor canal block-a randomized controlled double-blinded trial.
Femoral nerve block (FNB) is a well-established analgesic technique for TKA. However, it associates quadriceps weakness. Therefore, femoral triangle block (FTB) and adductor canal block (ACB) were proposed as effective alternative motor-spearing techniques. The primary objective was to compare quadriceps muscle strength preservation between FNB, FTB and ACB in TKA. The secondary objective was to analyze pain control and functional outcomes. ⋯ This study was registered in clinicaltrials.gov (NCT03518450; https://clinicaltrials.gov/ct2/show/NCT03518450 ; submitted March 17, 2018).

Cadaveric study investigating the femoral nerve-sparing volume for pericapsular nerve group (PENG) block.
This cadaveric study investigated the maximum effective volume of dye in 90% of cases (MEV90) required to stain the iliac bone between the anterior inferior iliac spine (AIIS) and the iliopubic eminence (IPE) while sparing the femoral nerve during the performance of pericapsular nerve group (PENG) block. ⋯ For PENG block, the MEV90 of methylene blue required to spare the femoral nerve in a cadaveric model is 13.2 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in live subjects.

Randomized Controlled TrialHigher intra-operative narcotic requirements and weakness with quadratus lumborum compared to paravertebral nerve block for total hip arthroplasty.
This was a prospective single-blinded study comparing the peri-operative opioid consumption and motor weakness for patients undergoing total hip arthroplasty (THA) with either a Quadratus Lumborum Type 3 Nerve Block (QLB) or a Paravertebral Nerve Block (PVB). ⋯ III, Non-randomized controlled cohort/follow-up study.

Shoulder dislocations are among the most common orthopedic emergencies encountered in the emergency department (ED). Ultrasound-guided peripheral nerve blocks (USG-PNBs) are increasingly being used for acute pain management in the ED, but clinical evidence supporting their utility for shoulder dislocation is limited and often conflicting. ⋯ USG-PNBs performed by adequately trained emergency physicians should be considered a safe and effective alternative for analgesia during closed reduction of dislocated shoulders in the ED, particularly in patients with cardiorespiratory comorbidities.
