Metabolic acid-base disorders are comnom clinical problems in ICU patients. Arterial blood gas analysis and anion gap (AG) are important laboratory data in approaching acid-base interpretation. When measuring the AG, several factors such as albumin have influence on unmeasured anions and unmeasured cations. If a patient has hypoalbuminemia, the AG should be adjusted according to the albumin lev...

III Einstein International Symposium on Intensive Care and the XXX Mechanical Ventilation. Aug 16-18, 2023. Category: Surgery Trauma Introduction: There is an expected relationship between Anion Gap (AG) elevation serum bicarbonate variation (deltaBic).() Thus, we can assess whether there are other associated metabolic disorders by calculating deltaAG/deltaBic.() Altered values indicate early s...

Both an arterial blood gas and a basic metabolic panel are necessary to determine a patient’s acid-base status. Analysis of a patient’s acid-base disorder includes identification of the primary disorder, calculation of the anion gap (AG), evaluation for the presence of excess acid or base, comparison of the expected and actual compensation, and explanation of the cause of each identified acid-b...

BACKGROUND This cohort study compared the prognostic significance of strong ion gap (SIG) with other acid-base markers in the critically ill. METHODS The relationships between SIG, lactate, anion gap (AG), anion gap albumin-corrected (AG-corrected), base excess or strong ion difference-effective (SIDe), all obtained within the first hour of intensive care unit (ICU) admission, and the hospita...

In this study, ZnO nanopowders and ZnO doped with metals (Cu , Ag- doped ZnO) and (Cd, Ag- doped ZnO) were synthesized by the sol-gel method in order to investigation on the codoping effect on the band gap and photocatalytic activity of ZnO. The synthesized samples are characterized by IR spectroscopy technique. Moreover, the absorption coefficients of the ZnO, Ag-Cd-ZnO and Ag-Cu-ZnO were anal...

abstract objective: to determine the correlation between blood gas parameters and central venous pressure (cvp) in patients suffering from septic shock. m e t h od s : forty adult patients with diagnosis of septic shock who were admitted to the emergency department (ed) of shohadaye tajrish hospital affiliated with shahid beheshti university of medical sciences, and met inclusion and exclusion ...

The asymmetric unit of the title coordination complex, [Ag2Br2(C5H8N2)2] n , comprises a monodentate 1-ethyl-imida-zole ligand, an Ag(+) cation and a μ3-bridging Br(-) anion, giving a distorted tetra-hedral AgNBr3 stereochemistry about the Ag(+) cation [Ag-N = 2.247 (2) Å and Ag-Br = 2.7372 (4)-2.7523 (4) Å]. Two bridging bromide anions generate the dimeric [Ag2Br2(C5H8N)2] repeat unit [Ag⋯Ag =...

Hyperchloremic metabolic acidosis in which the anion gap is within normal limits is a common condition in the hospital population, and often presents a difficult diagnostic problem. We describe nine typical cases of this disorder and suggest a logical approach to its evaluation.

The aims of this study were to determine whether standard base excess (SBE) is a useful diagnostic tool for metabolic acidosis, whether metabolic acidosis is clinically relevant in daily evaluation of critically ill patients, and to identify the most robust acid-base determinants of SBE. Thirty-one critically ill patients were enrolled. Arterial blood samples were drawn at admission and 24 h la...
