Comparison of various surrogate markers for venous congestion in predicting acute kidney injury following cardiac surgery: A cohort study.
Venous congestion has been demonstrated to increase the risk of acute kidney injury (AKI) after cardiac surgery. Although many surrogate markers for venous congestion are currently used in clinical settings, there is no consensus on which marker is most effective in predicting AKI. ⋯ Venous congestion is associated with AKI after cardiac surgery, but not necessarily with CRRT. Among the markers tested, IRVF exhibits the strongest correlation with AKI.

Smartphone applications for measuring noise in the intensive care unit: A feasibility study.
This study aims to explore the suitability of using smartphone applications with low-cost external microphones in measuring noise levels in intensive care units. ⋯ Smartphone apps and low-cost external microphones can be used reliably to measure the average noise level in the intensive care unit after acoustic calibration. However, professional equipment is still necessary for accurate measurement of the maximum noise level.

LetterA modified Gamblegram for the visual representation of acid-base disorders according to the Stewart-Figge approach.
The Gamblegram consists of two bars, each of which represents the sum of the charges of individual positively and negatively charged ions and is commonly used for visualizing changes in acid-base and electrolyte charges. However, according to the Stewart-Figge theory, the metabolic independent acid-base variables include the strong ion difference ([SID]) and the total concentrations of weak acids (albumin and inorganic phosphate), which are not shown in the conventional Gamblegram. ⋯ To overcome this problem the following modifications are proposed: 1) The positive bar is represented exclusively by strong ion difference ([SID]) 2) The negative bar is comprised of [HCO3̄], unmeasured ion charge ([X]) and albumin and inorganic phosphate charges which are considered proportional to their total concentrations assuming a standard pH of 7.4 (0.28⋅[Albumin] (g/l) and 1.8⋅[Phosphate] (mmol/l), respectively). The proposed method treats [HCO3̄] as a global index of the metabolic acid-base status, whose concentration is expressed as a function of the Stewart-Figge independent acid-base variables ([SID], [Albumin], [Phosphate] and [X]).
