This study aimed to determine whether modified shock index (MSI) is associated with mortality that is superior to heart rate, blood pressure, or the shock index (SI) in emergency patients. ⋯ MSI is a clinically significant predictor of mortality in emergency patients. It may be better than using heart rate and blood pressure alone. SI is not significantly correlated with the mortality rate of the emergency patient.

Induction of hypothermia (a 4 °C decrease from baseline) improves outcomes in adult cardiac arrest and neonatal hypoxic ischemic encephalopathy, and may benefit other conditions as well. Methods used to implement or prevent hypothermia typically require skin contact with blankets or pads or intravascular access with catheter devices. The study was to evaluate the potential to induce mild therapeutic hypothermia via an esophageal route in a porcine model. ⋯ A prototype of an esophageal cooling device induced hypothermia effectively in a large single-swine model.

In the management of critically ill patients, the assessment of volume responsiveness and the decision to administer a fluid bolus constitute a common dilemma for physicians. Static indices of cardiac preload are poor predictors of volume responsiveness. Passive leg raising (PLR) mimics an endogenous volume expansion (VE) that can be used to predict fluid responsiveness. This study was to assess the changes in stroke volume index (SVI) induced by PLR as an indicator of fluid responsiveness in mechanically ventilated patients with severe sepsis. ⋯ Changes in ΔSVI and ΔCVPm induced by PLR are accurate indices for predicting fluid responsiveness in mechanically ventilated patients with severe sepsis.

It has been estimated that up to one third of all emergency department (ED) visits may be "inappropriate" or non-emergent. Factors that have been speculated to be associated with non-emergent use have been noted to include low socioeconomic status, lack of access to primary care, lack of insurance, convenience of "on demand care" and the patient's individual perception of their complaint urgency. The objective of this study is to identify the reasons contributing to self-perceived non-emergent adult emergency department visits during primary care physician office hours of operation. ⋯ Our study did not identify a statistically significant factor to the reasoning behind why patients choose the emergency department over a primary care physician during regular office hours. The only significant demographic indicating who was more likely to make this choice during the specified time frame was being single and employed with perceived non-emergent complaint. Patients without insurance and/or without a primary care physician were no more likely to visit the emergency department with a self-perceived non-emergent issue than patients with insurance and/or with an established primary care physician.

This study aimed to determine the potential protective effect of inducing hypertransfusion to the gastrointestinal tract following a porcine model of cardiac arrest and cardiopulmonary resuscitation (CPR) by evaluating the influence of gastrointestinal ultrastructure, ATPase and serum diamine oxidase. ⋯ Gastrointestinal injury and abnormal energy metabolism were strikingly evident following CPR. Hypertransfusion inducing hypertension can improve energy metabolism and ameliorate gastrointestinal mucosal injury, indicating that hypothermia significantly ameliorates gastrointestinal injury sustained following cardiac arrest.
