Canadian Association of Radiologists Musculoskeletal System Diagnostic Imaging Referral Guideline.

The Canadian Association of Radiologists (CAR) Musculoskeletal System Expert Panel consists of musculoskeletal radiologists, a family physician, a sports and exercise medicine physician, emergency medicine physicians, a patient advisor, and an epidemiologist/guideline methodologist. After developing a list of 25 musculoskeletal clinical/diagnostic scenarios, a systematic rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for 1 or more of these clinical/diagnostic scenarios. Recommendations from 41 guidelines (50 publications) and contextualization criteria in the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) for guidelines framework were used to develop 124 recommendation statements across the 25 scenarios related to the evaluation of the musculoskeletal system. This guideline presents the methods of development and the recommendations for imaging in the context of musculoskeletal pain, infection, tumors, arthropathies, metabolic bone disease, stress injuries, orthopedic hardware, avascular necrosis/bone infarction, and complex regional pain syndrome.

Emergency department procedural sedation for primary electrical cardioversion - a comparison with procedural sedations for other reasons.

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia treated in the emergency department (ED), with primary electrical cardioversion (PEC) the preferred method of rhythm control. Anecdotally, patients undergoing ED procedural sedation (EDPS) for PEC differ from those requiring EDPS for other procedures: they are at higher risk of adverse events, and require fewer drugs and lower doses. We attempt to verify this using an EDPS registry at a Canadian, tertiary care teaching hospital. METHODS: This is a retrospective review of patients that underwent EDPS for the period of June 2006 to September 2014. We compared demographics, medication use and intra-procedural adverse events between those receiving EDPS for PEC for AF compared to that for other indications. We report the asssociation between AEs and predictors using logistic regression. RESULTS: A total of 4 867 patients were included, 714 for PEC for AF and 4 153 for other indications. PEC patients were more likely male (58.5% vs. 47.1%), older (59.5 years vs. 48.1 years), and less likely to be ASA I (46.6% vs. 69.0%). PEC patients received smaller doses of propofol and less likely to receive adjuvant analgesic therapy (11.5% vs. 78.2%). PEC patients were more likely to experience hypotension (27.6% vs. 16.5%) but respiratory AEs (apnea, hypoxia and airway intervention) were not different. CONCLUSION: EDPS for PEC differs from that conducted for other purposes: patients tend to be less healthy, receive smaller doses of medication and more likely to suffer hypotension without an increase in respiratory AEs. These factors should be considered when performing EDPS.

Emergency Procedural Sedation With Propofol in Older Teenagers: Any Cause for Concern?

INTRODUCTION: Propofol is a standard for adult emergency department procedural sedation (EDPS). Use in pediatric patients remains controversial. Our primary objective was to investigate whether adverse events occurred more frequently in teenage pediatric patients receiving propofol for EDPS. METHODS: This retrospective study examines records from the Halifax Procedural Sedation Registry, collected between January 1, 2006 and May 31, 2013. Patients undergoing EDPS using propofol were divided into those aged 16 to 19 years (teenagers), 20 to 65 years (adults), and older than 65 years (seniors). The primary outcomes were the incidences of hypotension and hypoxia. RESULTS: Four thousand sixty-three EDPSs were included in the analysis, of which 230 involved teenagers, 2853 adults (mean age, 43.0 years), and 980 seniors (mean age, 77.1). The teenage group was significantly less likely to develop hypotension or hypoxia. These differences were confirmed on multivariate analysis. Patients in the teenage group received higher doses of propofol per kilogram/minute than the other groups. No other differences met statistical significance. CONCLUSIONS: Teenage patients receiving EDPS with propofol had a lower incidence of adverse events, and both received and tolerated larger adjusted doses of medication than older patients. Satisfaction and duration of EDPS were similar. Concerns about propofol use in younger patients have not been supported by this study. We believe that these findings support the use of propofol for EDPS in older teenagers.

Aspiration pneumonitis requiring intubation after procedural sedation and analgesia: a case report.

Emergency department (ED) procedural sedation and analgesia is widely and routinely performed; serious complications are rare. We describe the first reported case of aspiration during procedural sedation in the ED. Although our patient required endotracheal intubation and critical care admission, there was no adverse long-term outcome. Given that there were no apparent predisposing factors, we believe it is crucial for emergency physicians to routinely anticipate the possibility of such a complication during each sedation event.
