Active clinical trials for "Acidosis"

The investigators conducted a randomized controlled trial (parallel group study with 1:1 randomisation) comparing early cord clamping (ECC, at 60 seconds) and delayed cord clamping (DCC, at 180 seconds) in 90 cases of 'normal', two-step vaginal deliveries. DCC may result in a higher blood volume in the newborn, facilitating the maternal-placental-fetal exchange of circulating compounds, without potentially detrimental acidosis.

Dichloroacetate (DCA) is a product of water chlorination and a metabolite of certain industrial solvents, thus making it a chemical of environmental concern. However, DCA is also used as an investigational drug for treating various diseases of adults and children, at doses far greater than those to which humans are normally exposed in the environment. Our research involves how DCA is metabolized by healthy adults and by children with a fatal genetic disease, congenital lactic acidosis (CLA) who are treated with DCA.

OBJECTIVES: I. Study the metabolism of pyruvate and related problems in patients with lactic acidemia. II. Define the nature of the metabolic defect.

Alterations of acid-base equilibrium are very common in critically ill patients and understanding their pathophysiology can be important to improve clinical treatment. The human organism is protected against acid-base disorders by several compensatory mechanisms that minimize pH variations in case of blood variations in carbon dioxide content. The aim of the present study is to quantify the buffer power, i.e. the capacity to limit pH variations in response to carbon dioxide changes, in critically ill septic patients and compare these results with data collected from healthy volunteers.

The purpose of this study is to assess brain and memory changes in patients with uncontrolled diabetes (a condition called diabetic ketoacidosis (DKA))

This observational study evaluates the potential benefits, costs and clinical outcomes of albumin over saline and other non-saline fluids in patients receiving large volume resuscitation.

Study Title: The Impact of the pH on cardiac function in the critically ill patient Sponsor: King's College Hospital NHS Foundation Trust Chief Investigator: Dr Sancho Rodríguez-Villar IRAS Number: 227870 Hypothesis: Titration studies in animals with normal cardiac function show that a reduction in blood pH (and presumably that of the intracellular and interstitial compartments) from the normal level of 7.40 to 7.20 is associated with a rise in cardiac output. However, when blood pH is less than 7.20, cardiac output is reduced. Similar studies in humans with or without normal cardiac function have not been done, and yet blood pH at which aggressive treatment is recommended has been set at 7.20 based solely on animal experiments. The investigators hypothesize that a change in blood pH in humans will also affect cardiac function, but the level of blood pH at which this is observed might be similar or different in humans. In addition, the presence or absence of underlying cardiac disease and the type of acid-base abnormality present might modify the response of the heart to changes in blood pH. Primary Objectives: Assess whether there are significant changes in cardiac function associated with changes in blood pH. Relate the changes in cardiac function to the presence or absence of underlying cardiac disease. Study Design: A prospective multicenter observational study in 6 ICU´s (between two Trusts). During a year study period, a minimum of 300 patients will be recruited.

Purpose To compare the performance of the two currently employed urinary acidifications tests in stone formers, the furosemide/fludrocortisone and ammonium chloride loading test. To study the impact of polymorphisms in the genes ATP6V1B1, ATP6V0A4 and SLC4A1 on urinary acidification in stone formers.

From a central registry at the National Board of Health and Welfare in Sweden collect all patients in the city of Malmö prescribed metformin during two years. Glomerular filtration rate (eGFR) was estimated from the CKD-EPI formula (n=5408) and compared to a control material (n=2815) from the same town. All cases of severe lactic acidosis rendering ICU admission were also sought. The study hypothesis is that metformin is prescribed to patients with lower GFR than anticipated with very few cases of lactic acidosis registered.

Objective: Arterial blood gas (ABG) is essential in the clinical assessment of potential acutely ill patients venous to arterial conversion (v-TAC), a mathematical method, has recently been developed to convert peripheral venous blood gas (VBG) values to arterialized VBG (aVBG) values. The aim of this study is to test the reliability of aVBG compared to ABG in an intensive care unit (ICU) setting. Method: Consecutive patients admitted to the ICU with pH values <7,35 or >7,45 are included in this study. Paired ABG and aVBG samples are drawn from patients via arterial catheter, central venous catheter and/or peripheral venous catheter and compared.
