Although heatstroke is often associated with dehydration, the clinical significance of serum sodium abnormalities in patients with heat-related illness during heat wave has been poorly documented. ⋯ Serum sodium abnormalities are frequently observed in patients with a nonexertional heatstroke during heat wave; however, only hypernatremia should be considered as an independent risk factor of death. Rapid measurement of serum sodium concentration is mandatory to appropriately guide electrolyte resuscitation.

Young patients are at low risk for an acute coronary syndrome (ACS); however, many of these patients still enter a "rule-out ACS" pathway and receive stress testing. We hypothesized that stress testing in patients younger than 40 years without known coronary disease will not identify patients at high risk for 30-day adverse cardiovascular events. ⋯ The 30-day cardiovascular complication rate is not different between young patients without known heart disease who do and do not receive stress testing when they present with symptoms of a potential ACS. Testing of young patients at low risk for disease should be reconsidered.

The aim of this study was to assess the ability of the Sequential Organ Failure Assessment (SOFA), Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system, and Trauma and Injury Severity Score (TRISS) method to predict group mortality for intensive care unit (ICU) trauma patients. ⋯ The results from the present study showed that the SOFA score was not different from APACHE II scoring system and TRISS in predicting the outcomes for ICU trauma patients. However, the method for calculating SOFA scores is easier and simpler than APACHE II and TRISS.

Standard-length catheters vs long catheters in ultrasound-guided peripheral vein cannulation.
Ultrasound (US) is a useful tool for peripheral vein cannulation in patients with difficult venous access. However, few data about the survival of US-guided peripheral catheters in acute care setting exist. Some studies showed that the survival rate of standard-length catheters (SC) is poor especially in obese patients. The use of longer than normal catheters could provide a solution to low survival rate. The aim of the present study was to compare US-guided peripheral SCs vs US-guided peripheral long catheters inserted with Seldinger technique (LC) in acute hospitalized patients with difficult venous access. ⋯ Both SC and LC US-guided cannulations have a high success rate in patients with difficult venous access. Notwithstanding a higher time to cannulation, LC US-guided procedure is associated with a lower risk of catheter failure compared with SC US-guided procedure.

Our study compares treatment times of morbidly obese patients (body mass index [BMI]>40 kg/m2) with patients having BMI less than 35 kg/m2. ⋯ In our institution, morbidly obese patients take significantly longer to disposition home than patients of more normal weight.
