Randomized Controlled Trial Comparative Study
Randomized comparison of three guidewire insertion depths on incidence of arrhythmia during central venous catheterization.
Guidewire-induced arrhythmias that occur during central venous catheterization can progress to malignant arrhythmias in rare cases. This study compared the incidence of arrhythmia during central venous catheterization using three different depths of guidewire insertion into the right internal jugular vein. ⋯ During central venous catheterization through the right internal jugular vein, inserting guidewires to depths of 15 or 17.5cm before tissue dilation reduced the incidence of arrhythmic episodes compared to a depth of 20cm.

Multicenter Study Comparative Study Observational Study
Missed myocardial infarctions in ED patients prospectively categorized as low risk by established risk scores.
Few studies have prospectively compared multiple cardiac risk prediction scores. We compared the rate of missed acute myocardial infarction (AMI) in chest pain patients prospectively categorized as low risk by unstructured clinical impression, and by HEART, TIMI, GRACE, and EDACS scores, in combination with two negative contemporary cardiac troponins (cTn) available in the U.S. ⋯ Using their recommended cutpoints and non high sensitivity cTn, TIMI and unstructured clinical impression were the only scores with no missed cases of AMI. Using lower cutpoints (GRACE≤48, TIMI=0, EDACS≤11, HEART≤2) missed no case of AMI, but classified less patients as low-risk.

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.

Comparative Study
A retrospective analysis of nebulized versus intravenous fentanyl for renal colic.
To assess the effectiveness of nebulized fentanyl used for analgesia in renal colic. ⋯ Nebulized fentanyl provides effective analgesia in patients with renal colic. However, iv fentanyl exhibits more rapid and more powerful analgesic effects than nebulized fentanyl. Nonetheless, due to its ease of use and few potential risks and side-effects the nebulized form can be used as an alternative in renal colic.
