Observational StudyElectronic bed weighing vs daily fluid balance changes after cardiac surgery.
The purpose of this study is to establish the validity and reliability of measuring weight in critically ill patients with electronic weighing beds. ⋯ Body weight measured by electronic weighing beds does not seem sufficiently robust or accurate to replace daily FB in ICU. The clinical value of purchasing such beds remains uncertain.

Combat casualties undergoing lifesaving interventions have decreased heart rate complexity at multiple time scales.
We found that heart rate (HR) complexity metrics such as sample entropy (SampEn) identified patients with trauma receiving lifesaving interventions (LSIs). We now aimed (1) to test a multiscale entropy (MSE) index, (2) to compare it to single-scale measures including SampEn, and (3) to assess different parameter values for calculation of SampEn and MSE. ⋯ Complexity of HR dynamics over a range of time scales was lower in high-risk than in low-risk combat casualties and outperformed traditional vital signs.

Potential effect of physiotherapeutic treatment on mortality rate in patients with severe sepsis and septic shock: A retrospective cohort analysis.
The aim of the study was to examine the onset and frequency of physiotherapeutic interventions (PTI) and their potential effects on the intensive care unit (ICU) mortality rate in patients with severe sepsis or septic shock. ⋯ Physiotherapists routinely assess and treat patients with sepsis. The frequency of PTI was associated with an improved outcome. Prospective studies are necessary to confirm the potential favorable impact.

Observational StudyTissue oxygen saturation for the risk stratification of septic patients.
Peripheral tissue oxygen saturation (Sto2) has shown promise as an early indicator of tissue hypoperfusion and as a risk stratification tool in various forms of shock. The purpose of this study was to determine if Sto2 would predict admission to an intensive (ICU) or progressive care unit in patients with early signs of sepsis. ⋯ Low Sto2 levels in patients screening positive for sepsis are associated with an increased risk of ICU admission, but their reliability as a predictor is rather low. An Sto2 below 70% might be an interesting cutoff value for further study.

The purpose of this study is to describe the effect of levosimendan (without loading dose) on hemodynamics, inotropes/vasopressors, and mortality in acute heart failure (AHF). ⋯ Levosimendan, without a loading dose, improved cardiac index and perfusion while allowing a reduction in inotropic/vasopressor requirements in patients with AHF.
