Remote Ischemic Preconditioning During Cardiopulmonary Bypass

Lactic Acidosis

The objective of study is to detect effect of remote ischemic preconditioning on serum lactate levels during and after cardiac surgery with cardiopulmonary bypass in addition to its effect on cardiac and renal clinical outcomes.

Efficacy of Volume Ventilation in Patients With Acute Respiratory Failure at Risk of Obstructive...

Acute Respiratory FailureHypercapnic Respiratory Failure5 more

This study compares a volume targeted pressure support non-invasive ventilation with an automatic PEP regulation (AVAPS-AE mode) to a pressure support non-invasive ventilation (S/T mode) in patients with acute hypercapnic respiratory failure with acidosis. This study focuses on patients at risk of obstructive apneas or obesity-hypoventilation syndrom (BMI≥30 kg/m²). Half of participants (33 patients) will receive non invasive ventilation with AVAPS-AE mode, the other half will receive non-invasive ventilation with S/T mode.

Sodium Bicarbonate to Treat Severe Acidosis in the Critically Ill

Metabolic Acidosis

The purpose of the present study is to compare the adjunct treatment of metabolic or mixed severe acidosis in the critically ill using Sodium Bicarbonate as a buffer to increase the plasma pH vs no buffering therapy. The study is a randomized multiple center clinical trial with the outcome as a primary endpoint.

Development of Ketoacidosis During the Perioperative Period: an Observational Study 'The DKAP Study'...

KetosisKeto Acidosis6 more

Rationale: During perioperative period, prolonged starvation, surgical stress, acute complications (e.g. infection) and medication changes all promote ketone generation, therefore increasing the risk of ketoacidosis. At present, there is no literature concerning the ketone production in patients undergoing cardiac surgery, regardless of the diabetes status. Objectives: The objectives of this study are to explore the change in blood ketone level during the perioperative period in patients with and without diabetes, to observe the incidence of perioperative ketoacidosis, and to investigate therapy and outcome of patients with perioperative ketoacidosis.

Lactate Acidosis in Postoperative Hearts

Post-cardiac SurgeryHyperlactatemia

This is a single-center, observational study. Investigators aim to characterize the metabolism of lactate in children over the first forty-eight hours following cardiac surgery. Blood samples will be obtained up to 12 timepoints. Samples will be analyzed for concentration of pyruvate. Results will be compared to standard of care laboratory results for lactate and other direct and indirect measures of cardiac output.

Study of Blood Lactate Levels in Patients Treated With Antipsychotics

Movement DisordersLactic Acidosis

Blood lactate levels in patients receiving typical or atypical antipsychotics have not been described in the literature. The goal of this study is to assess the dynamics of lactate levels in the blood from typical or atypical antipsychotics not confounded by prior antipsychotic treatments, the investigators conducted a prospective study of lactate levels in patients receiving antipsychotic medication. The investigators hypothesized that 6 months of treatment with haloperidol or olanzapine would result in a change in blood lactate levels and extrapyramidal side effects.

Study On the Role of Mitochondrial Dysfunction in the Pathogenesis of Metformin-associated Lactic...

Lactic AcidosisMetformin

Metformin is the first line drug of choice for the treatment of type II diabetes. Lactic acidosis can develop as a side effect, especially when renal failure leads to drug accumulation. Lactic acidosis is usually attributed to an abnormal inhibition of hepatic lactate clearance. Growing evidence suggest that metformin can dose-dependently inhibit hepatocyte mitochondrial function. Whether a similar effect occurs in extra-hepatic human tissues remains unknown. The investigators hypothesize that mitochondrial dysfunction occurs during metformin intoxication even in tissues other than the liver, thus contributing to the development of lactic acidosis. The aim of this study is to investigate mitochondrial integrity in circulating platelets of patients with lactic acidosis due to metformin intoxication.

The Threshold of Serum Anion Gap as a Screening Tool for Organic Acidosis

Metabolic AcidosisCritical Illness4 more

Background: The serum anion gap (AG) is commonly used as a screening tool for acid-base disorders. With modern laboratory techniques using ion-selective electrodes to measure the main electrolyte components of the AG, our definition high AG (HAGMA) should be reviewed. Aim: This study aims to assess the diagnostic value of AG and to determine a diagnostic threshold for HAGMA in a high-prevalence clinical setting. Method: Computerized extraction of anonymised data from electronic medical records was performed. A pre-defined criteria included all inpatients of an acute-care hospital who had measurements for organic acids (lactate, ketone or salicylate) paired with a serum urea, electrolyte and creatinine panel.

The Effects of Hypothermia and Acidosis on Coagulation During Treatment With Rivaroxaban Measured...

TraumaHypothermia2 more

Rivaroxaban, a non-vitamin K oral anticoagulants, is increasingly used to prevent stroke in patients with atrium fibrillation. It has previously been demonstrated that a point-of-care coagulation instrument (ROTEM) can detect the effects of rivaroxaban. Further, the ROTEM instrument can also detect the effects of hypothermia and acidosis. Given that trauma induced coagulopathy is enhanced by both hypothermia, acidosis and rivaroxaban, the investigators want to investigate any synergistic effects between hypothermia or acidosis and rivaroxaban. In an attempt to do so the investigators designed the current experimental study with the purpose to investigate the effects of rivaroxaban together with hypothermia or acidosis using the ROTEM assay EXTEM. The hypothesis is that a synergistic prolongation of hypothermia or acidosis and rivaroxaban can be detected in the initiation of clot formation demonstrated in the primary outcome variable, clotting time of the ROTEM assay EXTEM. Secondary outcome variables include direct effect on clotting time and direct and synergistic effects on clot formation time and alfa angle of hypothermia and acidosis detected in the ROTEM assay EXTEM.
