ReviewReconfiguring the scope and practice of regional anesthesia in a pandemic: the COVID-19 perspective.
The COVID-19 outbreak is on the world. While many countries have imposed general lockdown, emergency services are continuing. Healthcare professionals have been infected with the virulent severe acute respiratory syndrome coronavirus-2 (SARS), which spreads by close contact and aerosols. ⋯ The perioperative anesthetic implications of multisystem manifestations of COVID-19, anesthetic management options, the scope of RA and considerations for its safe conduct in operating rooms is described. An outline for safe and rapid training of healthcare personnel, with an Entrustable Professional Activity framework for ascertaining the practice readiness among trained residents for RA in COVID-19, is suggested. These are the authors' experiences gained from the current pandemic and similar SARS, Middle East Respiratory Syndrome and influenza outbreaks in recent past faced by our authors in Singapore, India, Hong Kong and Canada.

Cervical erector spinae plane (ESP) block has been described to anesthetize the brachial plexus (BP), however, the mechanism of its clinical effect remains unknown. As the prevertebral fascia encloses the phrenic nerves, BP and erector spinae muscles to form a prevertebral compartment, a local anesthetic injected in the cervical ESP could potentially spread throughout the prevertebral compartment. This study utilizes cadaveric models to evaluate the spread of ESP injections at the C6 and C7 levels to determine whether the injection can reach the BP and its surrounding structures. ⋯ Ultrasound-guided cervical (C6 and C7) ESP injections consistently stain the roots of the BP and dorsal rami. This study supports the notion that the cervical ESP block has the potential to provide analgesia for patients undergoing shoulder and cervical spine surgeries.

CommentRegional anesthesia training model for resource-limited settings: a prospective single-center observational study with pre-post evaluations.
Educational initiatives are a sustainable means to address provider shortages in resource-limited settings (RLS), yet few regional anesthesia curricula for RLS have been described. We sought to design a reproducible training model for RLS called Global Regional Anesthesia Curricular Engagement (GRACE), implement GRACE at an RLS hospital in Ghana, and measure training and practice-based outcomes associated with GRACE implementation. ⋯ GRACE applied in an RLS hospital led to the design, implementation, and measurement of a regional anesthesia curriculum tailored to institutional specifications that was associated with positive Kirkpatrick outcomes.

Incidence and etiology of postoperative neurological symptoms after peripheral nerve block: a retrospective cohort study.
Nerve injury from peripheral nerve block (PNB) is an uncommon but potentially serious complication. We present a retrospective cohort study to evaluate the incidence and etiology of new postoperative neurological symptoms after surgery and regional anesthesia. ⋯ This retrospective review of 19 219 patients receiving PNBs for anesthesia or analgesia suggests that determining the etiology and causative factors of postoperative neurological symptoms is a complex, often challenging process that requires a multidisciplinary approach. We suggest a classification of cases based on the etiology. A most likely cause was identified in 70% of cases. This type of classification system can help broaden the differential diagnosis, help consider non-regional anesthesia and non-surgical causes and may be useful for clinical and research purposes.
