Increasing the size of the central veins is required to increase the success rate of central line placement and decrease complication risk. Right-sided approach for the central veins, Valsalva maneuver, and Trendelenburg position have been recommended, but these may not be available for some cases. This study aimed to determine a more convenient patient position that can result in the largest central vein diameter. ⋯ The LE without leg elevation produced a greater and more significant increase in central vein diameter than the supine position and may be useful for central line placement.

We evaluate in this retrospective cohort, the clinical situations leading emergency physicians to take a blood lactate sample, the prevalence of hyperlactatemia and its impact on short-term adverse outcome. ED patients requiring a blood lactate measurement (BLM) during a two-year period were included. Early patients' outcomes were extracted and discharge diagnoses were classified into 12 diagnostic categories. ⋯ The blood lactate level was very informative to detect the sicker patients in the infection group whereas its interest was poor in the group of patients admitted for seizures. In conclusion, blood lactate testing has become routine in emergency departments and a large proportion of patients have abnormal blood lactate levels. The most frequent causes of high blood lactate in the ED are infection and seizures but the prognostic value of blood lactate seems to be different from one diagnostic category to the other.

Epinephrine administration in non-shockable out-of-hospital cardiac arrest.
Epinephrine is recommended for the treatment of non-shockable out of hospital cardiac arrest (OHCA) to obtain return of spontaneous circulation (ROSC). Epinephrine efficiency and safety remain under debate. ⋯ An association between total cumulative epinephrine dose administered during OHCA resuscitation and ROSC- was reported with a threshold of 7 mg, best identifying patients with refractory OHCA. We suggest using this threshold in this context to guide the termination of ALS and early decide on the implementation of extracorporeal life support or organ harvesting in the first 30 min of ALS.

Observational Study
Push dose pressors: Experience in critically ill patients outside of the operating room.
Evaluate push dose vasopressor (PDP) practice patterns, efficacy, and safety in critically ill patients. ⋯ PDPs were used in a variety of patient diagnoses and for select indications. Overall, they were efficacious but associated with adverse drug events and medication errors.

Effects of an emergency transfer coordination center on secondary overtriage in an emergency department.
Patients who cannot be stabilized at a lower-level emergency department (ED) should be transferred to an upper-level ED by emergency medical services. However, some patients are subsequently discharged after transfer without any intervention or admission, and this secondary overtriage (SO) wastes the limited resources of upper-level EDs. This study aimed to investigate whether an emergency transfer coordination center (ETCC) could reduce the risk of SO among patients who were transferred to a tertiary ED by emergency medical services. ⋯ Transfers that were evaluated by an ETCC had a lower risk of SO, which may improve the appropriateness of transfer. Thus, tertiary EDs that have high proportions of transferred patients should have a transfer coordination system that is similar to an ETCC.
