Randomized Controlled Trial Comparative StudyComparison of the effectiveness of circumferential versus non-circumferential spread in median and ulnar nerve blocks. A double-blind randomized clinical trial.
Circumferential (C) spread of local anesthetic around the nerve is recommended for a successful nerve block. We tested the hypothesis that C spread produces a more complete block than non-circumferential (NC) spread. ⋯ C spread around the median and ulnar nerves at the level of the antecubital fossa generates more complete sensory and motor blocks compared with NC spread.

Multicenter StudyMulticenter longitudinal cross-sectional study comparing effectiveness of serratus anterior plane, paravertebral and thoracic epidural for the analgesia of multiple rib fractures.
There is a paucity of data comparing effectiveness of various techniques for pain management of traumatic rib fractures. This study compared the quality of analgesia provided by serratus anterior plane (SAP) catheters against thoracic epidural (TEA) or paravertebral catheters (PA) in patients with multiple traumatic rib fractures (MRFs). ⋯ SAP, TEA and PA all appear to offer the ability to reduce pain scores and improve respiratory function.

A cadaveric study of the erector spinae plane block in a neonatal sample.
The aim of this article was to provide a detailed description of the neonatal anatomy related to the erector spinae plane block and to report the spread of the dye within the fascial planes and potential dermatomal coverage. ⋯ In two neonatal fresh cadavers, the dye was found to spread to multiple levels and key anatomic locations.

Lack of July effect in the utilization of neuraxial and peripheral nerve block in US teaching hospitals: a retrospective analysis.
Given the steep learning curve for neuraxial and peripheral nerve blocks, utilization of general anesthesia may increase as new house staff begin their residency programs. We sought to determine whether "July effect" affects the utilization of neuraxial anesthesia, peripheral nerve blocks, and opioid prescribing for lower extremity total joint arthroplasties (TJA) in July compared with June in teaching and non-teaching hospitals. ⋯ Utilization of neuraxial and regional anesthesia techniques was not affected during the initial transition period of new house staff in US teaching institutions. It is feasible that enough resources are available in the system to accommodate periods of turnover and maintain levels of regional anesthetic care including additional attending anesthesiologist oversight.
