Randomized Controlled Trial
The Effect of Nebulized Albuterol on Serum Lactate and Potassium in Healthy Subjects.
The objectives were to determine if nebulized albuterol causes an increase in the serum lactate level compared to placebo and, secondarily, to confirm that albuterol decreases serum potassium levels compared to placebo in patients with normokalemia. ⋯ Nebulized albuterol increases lactate levels and decreases potassium levels in healthy adults.

Observational Study
First Pass Success without Hypoxemia is Increased with the Use of Apneic Oxygenation During RSI in the Emergency Department.
The objective was to determine the effect of apneic oxygenation (AP OX) on first pass success without hypoxemia (FPS-H) in adult patients undergoing rapid sequence intubation (RSI) in the emergency department (ED). ⋯ The use of AP OX during the RSI of adult patients in the ED was associated with a significant increase in FPS-H. These results suggest that the use of AP OX has the potential to increase the safety of RSI in the ED by reducing the number of intubation attempts and the incidence of hypoxemia.

The pyruvate dehydrogenase complex (PDH) is an essential enzyme in aerobic metabolism. Ketones are known to inhibit PDH activity, but the extent of this inhibition is unknown in patients with diabetic ketoacidosis (DKA). ⋯ DKA is associated with greater suppression of PDH activity than hyperglycemia without ketoacidosis, and this is correlated with measures of acid-base status. Future studies may determine whether PDH depression plays a role in the pathophysiology of DKA and whether modification of PDH could decrease time to DKA resolution.

Randomized Controlled Trial Comparative Study
Comparison of Intravenous Morphine vs Paracetamol in Sciatica: A Randomized Placebo Controlled Trial.
The objective was to compare intravenous morphine and intravenous acetaminophen (paracetamol) for pain treatment in patients presenting to the emergency department with sciatica. ⋯ Morphine and acetaminophen are both effective for treating sciatica at 30 minutes. However, morphine is superior to acetaminophen.
