Randomized Controlled TrialRandomized clinical trial comparing pericapsular nerve group (PENG) block and periarticular local anesthetic infiltration for total hip arthroplasty.
This randomized trial compared pericapsular nerve group block and periarticular local anesthetic infiltration in patients undergoing primary total hip arthroplasty. We hypothesized that, compared with pericapsular nerve group block, periarticular local anesthetic infiltration would decrease the postoperative incidence of quadriceps weakness at 3 hours fivefold (ie, from 45% to 9%). ⋯ For primary total hip arthroplasty, pericapsular nerve group block and periarticular local anesthetic infiltration result in comparable rates of quadriceps weakness. However, periarticular local anesthetic infiltration is associated with lower static pain scores (especially during the first 24 hours) and dynamic pain scores (first 6 hours). Further investigation is required to determine the optimal technique and local anesthetic admixture for periarticular local anesthetic infiltration.

Reactivation of Herpes Simplex Virus Following Sphenopalatine Ganglion Nerve Block: Case Report and Review of the Literature.
A 36-year-old woman with no significant past medical history underwent a sphenopalatine ganglion block for treatment of a month-long migraine headache refractory to conservative treatment protocols. The headache resolved initially, but 1 day following the procedure, the headache recurred. ⋯ Following several unsuccessful treatment modalities, the patient received valacyclovir, which resulted in resolution of her headache. Underlying HSV-1 infection may cause intractable migraine headache and nerve blocks may potentiate reactivation of latent HSV infection that caused the skin lesion in this case.

Evaluating two approaches to the erector spinae plane block: an anatomical study.
Studies show variable spread with thoracic erector spinae plane (ESP) injections. Injection sites vary from lateral end of the transverse process (TP) to 3 cm from the spinous process, with many not describing the precise site of injection. This human cadaveric study examined dye spread of ultrasound-guided thoracic ESP block at two needle locations. ⋯ An ESP injection administered between TPs exhibits more extensive spread than a medial TP injection in a human cadaveric model.

Outcome comparison of femoral nerve block and adductor canal block during anterior cruciate ligament reconstruction: adductor canal block may cause an unexpected decrease in knee flexor strength at 6 months postoperatively.
Peripheral nerve blocks are frequently used in anterior cruciate ligament (ACL) reconstruction. While femoral nerve block (FNB) has been associated with knee extensor strength reduction in the early postoperative period, no consistent view of knee extensor strength several months after ACL reconstruction exists. This study aimed to compare the impact of intraoperative FNB and adductor canal block (ACB) during ACL reconstruction on knee extensor strength at 3 and 6 months postoperatively. ⋯ Level III.
