Ultrasound-guided regional anesthesia simulation: use of meat glue in inexpensive and realistic nerve block models.
Ultrasound-guided regional anesthesia (UGRA) is increasingly used by emergency physicians to provide safe and effective pain relief for patients. However, one of the factors limiting its widespread use is the lack of realistic models available for learners to train on. There are currently no inexpensive nerve block models available that are injectable and that closely mimic nerves, fascial planes, muscles, and other landmarks. Our aim is to create inexpensive, injectable nerve block models that can be used as effective medical training tools for UGRA. ⋯ We have developed inexpensive and easily reproducible models that create the realistic appearance of tissues, nerves, and fascial planes under ultrasound. They can also accurately simulate hydrodissection of fluid in fascial planes. We hope these nerve block models will allow for the education in UGRA to be more widespread and accessible to learners from all specialties.

A healthy, 34-year-old primigravida at 41 weeks gestational age presented for cesarean delivery due to a category 2 fetal heart tracing remote from delivery. After completion of the surgery under epidural anesthesia, bilateral quadratus lumborum blocks were performed for postoperative pain. ⋯ These symptoms resolved within 24 hours. Considering the time course of her symptoms, we believe that the quadratus lumborum block was the likely culprit.

Randomized Controlled Trial
Ultrasound-guided adductor canal block using levobupivacaine versus periarticular levobupivacaine infiltration after totalknee arthroplasty: a randomized clinical trial.
Both postoperative pain control and range of motion are important in total knee arthroplasty (TKA). However, in the literature, there is little comparison of peripheral nerve blocks and periarticular infiltration techniques using levobupivacaine. The aim of our study was to measure pain with visual analogue scale (VAS) and knee range of motion (ROM) between in patients undergoing adductor canal block (ACB) for TKA using levobupivacaine compared to periarticular levobupivacaine infiltration (PAI-L). ⋯ ACTRN-12618000438257.

Ultrasound-guided infiltration of the interspace between the popliteal artery and capsule of the knee (iPACK) block, a new regional analgesic technique, is believed to relieve posterior knee pain, after total knee arthroplasty, by targeting the articular branches innervating posterior aspect of the joint. The extent of injectate spread and the number of articular branches affected is currently unknown. This cadaveric study aimed to compare the area of dye spread and frequency of articular branches staining following a proximal versus distal injection technique. ⋯ Both proximal and distal iPACK injection techniques provided a similar area of dye spread in the popliteal region and extensive staining of the articular branches supplying the posterior capsule. The proximal injection technique promoted greater anteromedial dye spread, while the distal injection had more anterolateral spread. Further clinical study is required to confirm our cadaveric findings. .

Randomized Controlled Trial
Effects of fluoroscopy-guıded intraartıcular injectıon, suprascapular nerve block, and combınatıon therapy ın hemıplegıc shoulder paın: a prospective double-blınd, randomızed clınıcal study.
To investigate the effect and superiority of fluoroscopy-guided intraarticular shoulder injection (IAI), suprascapular nerve block (SSNB), and combination treatment in hemiplegic shoulder pain (HSP). ⋯ IAI, SSNB, and the combination treatments are reliable and effective treatment modalities that provide pain relief and an increase in shoulder passive ROMs in HSP.
