Ultrasound-guided regional anesthesia: feasibility and effectiveness of teaching via telesimulation in Ethiopia.
Acute pain management in resource-poor countries remains a challenge. Ultrasound-guided regional anesthesia is a cost-effective way of delivering analgesia in these settings. However, for financial and logistical reasons, educational workshops are inaccessible to many physicians in these environments. Telesimulation provides a way of teaching across distance by using simulators and video-conferencing software to connect instructors and students worldwide. We conducted a prospective study to determine the feasibility of ultrasound-guided regional anesthesia teaching via telesimulation in Ethiopia. ⋯ Teaching ultrasound-guided regional anesthesia of the femoral nerve remotely via telesimulation is feasible. Telesimulation can greatly improve the accessibility of ultrasound-guided regional anesthesia teaching to physicians in remote areas.

Effect of preoperative cannabis use on perioperative outcomes: a retrospective cohort study.
The reported use of cannabis within surgical population is increasing. Cannabis use is potentially associated with increased harms and varied effects on pain control. These have important implications to perioperative care. ⋯ Our results do not demonstrate a convincing association between self-reported cannabis use and major surgical outcomes or pain management. Perioperative decisions should be made based on considerations of dose, duration, and indication.

Misalignment of measures, measurement and analysis with the goals and methods of quality improvement efforts in healthcare may create confusion and decrease effectiveness. In healthcare, measurement is used for accountability, research, and quality improvement, so distinguishing between these is an important first step. Using a case vignette, this paper focuses on using measurement for improvement to gain insight into the dynamic nature of healthcare systems and to assess the impact of interventions. ⋯ SPC provides ongoing assessment of system functioning and enables an improvement team to assess the impact of its own interventions and external forces on the system. Once improvement work is completed, the Standards for Quality Improvement Reporting Excellence (SQUIRE) guidelines is a valuable tool to describe the rationale, context, and study of the interventions. SQUIRE can be used to plan improvement work as well as structure a manuscript for publication in peer-reviewed journals.

MRI and muscle enzymes do not support the diagnosis of local anesthetic myotoxicity: a descriptive case series.
The presence of thigh muscle edema as characterized by increased signal intensity on MRI has been used to support the diagnosis of presumed local anesthetic-induced myotoxicity reported after total knee arthroplasty (TKA) with continuous adductor canal block (CACB). However, neither postoperative baseline imaging appearance nor muscle enzyme values have been described in conjunction with this clinical scenario. Thus, the usefulness of MRI or enzymatic biomarkers of muscle injury for supporting the diagnosis of local anesthetic myotoxicity is unknown. ⋯ The non-specificity of these findings suggests that MRI and near normal muscle enzyme levels are of limited diagnostic value when there is clinical suspicion of local anesthetic myotoxicity in the setting of TKA with CACB.

Anatomy of the thoracic paravertebral space: 3D micro-CT findings and their clinical implications for nerve blockade.
A precise anatomical understanding of the thoracic paravertebral space (TPVS) is essential to understanding how an injection outside this space can result in paravertebral spread. Therefore, we aimed to clarify the three-dimensional (3D) structures of the TPVS and adjacent tissues using micro-CT, and investigate the potential routes for nerve blockade in this area. ⋯ A non-destructive, multi-sectional approach using 3D micro-CT more comprehensively demonstrated the real topography of the intricate TPVS than previous cadaver studies. The posterior boundary and connectivity of the TPVS provides an anatomical rationale for the notion that paravertebral spread can be achieved with an injection outside this space.
