Acute gastroenteritis is characterized by diarrhea, which may be accompanied by nausea, vomiting, fever, and abdominal pain. ⋯ In the ED, dehydration is evaluated by synthesizing the historical and physical examination, and obtaining laboratory data points in select patients. No single laboratory value has been found to be accurate in predicting the degree of dehydration and this is not routinely recommended. The evidence suggests that the majority of children with mild to moderate dehydration can be treated successfully with oral rehydration therapy. Ondansetron (orally or intravenously) may be effective in decreasing the rate of vomiting, improving the success rate of oral hydration, preventing the need for i.v. hydration, and preventing the need for hospital admission in those receiving i.v. hydration.

Multicenter Study
The effects of emergency department staff rounding on patient safety and satisfaction.
Two recent inpatient studies documented that regular nursing staff rounding increased patient safety and satisfaction. However, the effect of systematic emergency department (ED) staff rounding on patient safety and satisfaction has not been adequately tested. ⋯ Rounding in the ED reception and treatment areas is effective and improves outcomes. Further research should determine the optimal design for rounding considering the mixed shifts in EDs, seek ways to increase communicating delays to patients, and investigate how to integrate rounding with physician activities.

Previous studies established that a level of partial pressure end-tidal carbon dioxide (P(ET)CO(2)) of 10 mm Hg divided patients undergoing advanced life support (ALS) into those likely to be resuscitated (values > 10 mm Hg) and those likely to die during ALS (values < 10 mm Hg). ⋯ In constantly ventilated patients, P(ET)CO(2) is significantly higher (about 10 mm Hg) after ROSC than before ROSC. A sudden increase in P(ET)CO(2) exceeding 10 mm Hg may indicate ROSC. Consequently, the rule of 10 mm Hg may be extended to include a sudden increase in continuously recorded P(ET)CO(2) by more than 10 mm Hg as an indicator of the possibility of ROSC.

Early optimization of fluid status is of central importance in the treatment of critically ill patients. This study aims to investigate whether inferior vena cava (IVC) diameters correlate with invasively assessed hemodynamic parameters and whether this approach may thus contribute to an early, non-invasive evaluation of fluid status. Thirty mechanically ventilated patients with severe sepsis or septic shock (age 60 +/- 15 years; APACHE-II score 31 +/- 8; 18 male) were included. ⋯ In this study, IVC diameters were found to correlate with central venous pressure, extravascular lung water index, intrathoracic blood volume index, the intrathoracic thermal volume, and the PaO(2)/FiO(2) oxygenation index. Therefore, sonographic determination of IVC diameter seems useful in the early assessment of fluid status in mechanically ventilated septic patients. At this point in time, however, IVC sonography should be used only in addition to other measures for the assessment of volume status in mechanically ventilated septic patients.

This study was designed to determine the validity of a central eschar with surrounding cellulitis as a clinical predictor for CA-MRSA infection. In this 10-month prospective observational study, patients with a chief complaint or clinical findings of skin infection with abscess had study data sheets placed on their chart. All abscesses were treated with incision and drainage, and wound cultures were obtained. ⋯ Three of these were positive for central black eschar, yielding a specificity of 92% (95% CI 0.83-1.01). The positive predictive value was 94% (95% CI 0.88-1.01) and the negative predictive value was 45% (95% CI 0.32-0.59). A central black eschar with cellulitis has good specificity and high positive predictive value in diagnosing CA-MRSA infection.
