Propofol versus midazolam for procedural sedation in the emergency department: A study on efficacy and safety.
Procedural sedation for painful procedures in the emergency department (ED) can be accomplished with various pharmacological agents. The choice of the sedative used is highly dependent on procedure- and patient characteristics and on personal- or local preferences. ⋯ A total of 592 ED sedations were included in our study. Patients sedated with propofol (n=284, median dose 75mg) achieved a deeper level of sedation (45% vs. 25% deep sedation, p<0.001), had a higher procedure success rate (92% vs. 81%, p<0.001) and shorter median sedation duration (10 vs. 17min, p<0.001) compared to patients receiving midazolam (n=308, median dose 4mg). A total of 112 sedation events were registered for 99 patients. Transient apnea was the most prevalent event (n=73), followed by oxygen desaturation (n=18) airway obstruction responsive to simple maneuvers (n=13) and hypotension (n=6). Propofol sedations were more often associated with the occurrence of apnea's (20% vs. 10%, p=0.004), whereas clinically relevant oxygen desaturations (<90%) were found more often in patients sedated with midazolam (8% vs. 1%, p=0.001). No sedation adverse events were registered CONCLUSION: Propofol is more effective and at least as safe as midazolam for procedural sedation in the ED.

Nonrheumatic myopericarditis is an uncommon complication of acute pharyngitis caused by Group A Streptococcal infection (GAS). While the natural history of carditis complicating acute rheumatic fever is well established, the incidence, pathophysiology and clinical course of nonrheumatic myopericarditis are ill defined. Advances in rapid bedside testing for both myocardial injury and GAS pharyngitis have allowed for increasing recognition of this uncommon complication in patients presenting with a sore throat with associated chest discomfort. We describe a case of a 34years old man with GAS pharyngitis complicated by acute myopericarditis who presented with chest pain, ST segment elevation on electrocardiogram, and elevated cardiac biomarkers.

Numb chin syndrome (NCS) is a rare yet potentially ominous sensory neuropathy in the distribution of the mental or inferior alveolar nerve characterized by unilateral hypoesthesia over the lower lip, chin and occasionally gingival mucosa. Recognizing NCS is clinically important as this may be a subtle sign of occult malignancy progression or heralding the relapses. ⋯ Current expert opinion is that patients with NCS without apparent cause should be assumed to have a malignant etiology until proven otherwise Lossos and Siegal (1992) [1]. Here we report a relapse of Non-Hodgkin lymphoma with NCS with no evidence of metastasis.

Esophageal foreign body (EFB) and impaction are common gastrointestinal emergencies. Detection with standard imaging can be challenging. Computed tomography is a commonly used non-invasive imaging modality, but is not 100% sensitive and not always feasible. Sensitivity of plain film x-ray varies widely and the addition of a barium swallow can obscure evaluation by subsequent esophagogastroduodenoscopy (EGD). Use of emergency ultrasound (EUS) for detection of EFB in adults has not been previously studied. ⋯ In patients with suspected EFB, point-of-care ultrasound may identify those with impaction. Suggestive findings include cervical esophageal dilatation and persistent intraluminal air-fluid levels after swallowing. EUS is a rapid, convenient test with the potential to expedite definitive management while decreasing cost and radiation exposure in this patient population.

We investigated seasonal prevalence of hyponatremia in the emergency department (ED). ⋯ We observed a major influence of climate on the prevalence of hyponatremia in the elderly in the ED. Decline in renal function, salt loss, reduced salt intake and increased water ingestion could all contribute to developing hyponatremia in elderly patients during the summer. These data could be useful for emergency physicians to prevent hot weather-induced hyponatremia in the elderly.
