Randomized Controlled Trial Comparative Study Clinical Trial
Two-thumb vs. two-finger chest compression in an infant model of prolonged cardiopulmonary resuscitation.
Previous experiments in the authors' swine lab have shown that cardiopulmonary resuscitation (CPR) using two-thumb chest compression with a thoracic squeeze (TT) produces higher blood and perfusion pressures when compared with the American Heart Association (AHA)-recommended two-finger (TF) technique. Previous studies were of short duration (1-2 minutes). The hypothesis was that TT would be superior to TF during prolonged CPR in an infant model. ⋯ In this infant CPR model, TT chest compression produced higher MAP, SBP, DBP, and PP when compared with TF chest compression during a clinically relevant duration of prolonged CPR.

Comparative Study Clinical Trial
Can clinical parameters predict fractures in acute pediatric wrist injuries?
Fractures around the wrist are common in pediatric patients presenting to the emergency department (ED). This pilot study was aimed at identifying clinical variables that are most likely to be associated with a fracture. ⋯ Distal radius point tenderness and a 20% or more decrease in grip strength were predictive of fractures.

Comparative Study
Calcium and digoxin vs. calcium alone for severe verapamil toxicity.
Calcium chloride (CaCl(2)) is ineffective in severe calcium channel antagonist overdoses. Digoxin increases intracellular calcium by inhibiting the sodium-potassium adenosine triphosphatase enzymes. ⋯ In a model of severe verapamil toxicity, digoxin plus calcium raised SBP and did not result in ventricular arrhythmias when compared with calcium alone.

Cutaneous wound healing in adults invariably results in scarring; however, there are few scales to quantify the degree of such scarring. The authors developed a histomorphologic scale for quantifying scarring after cutaneous burn injury. ⋯ A new reliable histomorphologic method for quantifying and scoring cutaneous scars is described together with a reliable scar VAS. However, these two scales are not highly correlated.

To determine the accuracy of POCT quality control testing of an ED maintained ABG Analyzer (Gem Premier)-Instrumentation Laboratory). ⋯ ED attendings are capable of quality control maintenance of an ABG analyzer as a POCT device under the quality control testing parameters set forth by the College of American Pathologists.
