Randomized Controlled TrialRandomized trial comparing the spread of erector spinae block with the combination of erector spinae block and retrolaminar block in soft embalmed Thiel cadavers.
Erector spinae plane (ESP) and retrolaminar (RL) blocks show unreliable spread. We hypothesize that the combination of ESP and RL blocks provides more extensive and reliable spread of dye than single ESP blocks. Our primary objective was to compare the spread of dye to the paravertebral spaces after the combination block and ESP block in Thiel embalmed cadavers. Spread, the primary end point, was defined as the number of paravertebral spaces colored with dye per injection. ⋯ In conclusion, the combination of ESP and RL blocks was more extensive and reliable than ESP block alone.

Ultrasound guided nerve blocks have become a popular tool in the armamentarium for pain physicians because of its advantages over fluoroscopy by offering portable, radiation-free and real-time imaging. But ultrasound guided procedures require training and practice to gain the expertise. There is a scarcity of review articles describing ultrasound guided injections techniques for nerve blocks of the head and neck. ⋯ Ultrasound guided nerve blocks of the head and neck are useful techniques for pain physicians to learn.

Randomized Controlled Trial
Postoperative analgesic effectiveness of ultrasound-guided transmuscular quadratus lumborum block in congenital hip dislocation surgery : A randomized controlled study.
Congenital hip dysplasia (CHD) defines a spectrum of pathologies in which the acetabulum and proximal femur of babies and children abnormally develop. Open surgery in congenital hip dysplasia leads to severe postoperative pain. The aim of this study was to evaluate the effectiveness of ultrasound-guided quadratus lumborum block (QLB) in pediatric patients undergoing surgery for congenital hip dysplasia. ⋯ Ultrasound-guided quadratus lumborum block reduces pain scores and analgesic requirements following congenital hip dysplasia surgery.
