Multicenter Study Comparative Study
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.

Review Case Reports
Delayed cardiac tamponade: A rare but life-threatening complication of catheter ablation.
Delayed cardiac tamponade (DCT) is a rare and life-threatening complication of catheter ablation performed as a treatment of atrial fibrillation, with few cases described in the medical literature. We present the case of a 57year-old man presenting with DCT 61days following a catheter ablation procedure. To the best of our knowledge, this is the most delayed case of cardiac tamponade (CT) following catheter ablation described in the literature. ⋯ Some proposed mechanisms of DCT include small pericardial hemorrhages following post-procedural anticoagulation or rupture of the sealed ablation-induced left atrial wall [2]. Clinical examination and electrocardiography may be helpful. However, the criterion standard for diagnosing CT is echocardiography [3].

Case Reports
Hyperbaric oxygen therapy for the prevention of arterial gas embolism in food grade hydrogen peroxide ingestion.
Food grade hydrogen peroxide ingestion is a relatively rare presentation to the emergency department. There are no defined guidelines at this time regarding the treatment of such exposures, and providers may not be familiar with the potential complications associated with high concentration hydrogen peroxide ingestions. In this case series, we describe four patients who consumed 35% hydrogen peroxide, presented to the emergency department, and were treated with hyperbaric oxygen therapy. ⋯ Hyperbaric oxygen therapy is an effective treatment for patients with vascular gas emboli after high concentration hydrogen peroxide ingestion. It is the treatment of choice for any impending, suspected, or diagnosed arterial gas embolism. Further research is needed to determine which patients with portal venous gas emboli should be treated with hyperbaric oxygen therapy.
