Filter by:Propofol has been routinely used for general anesthesia during pediatric cardiopulmonary bypass at our institution without complications. However, propofol may cause propofol infusion syndrome (PRIS), a rare, but often fatal complication mainly defined by bradycardia with progress to asystolia. Metabolic acidosis is regarded as an early warning sign of PRIS. Due to the preconditioning effects of sevoflurane and its availability for cardiopulmonary bypass, propofol has recently been substituted by sevoflurane during pediatric cardiopulmonary bypass at our institution. In this study the effect of substituting propofol by sevoflurane on metabolic acidosis and outcome are examined.
Propofol is routinely used for general anesthesia during pediatric heart catheterisation. Propofol infusion syndrome (PRIS) is a rare, but often fatal complication mainly defined by bradycardia with progress to asystolia during propofol infusion. Metabolic acidosis is regarded as an early warning sign of PRIS. In this study the effect of propofol and sevoflurane on serum base excess, pH and lactate are examined during pediatric heart catheterisation.
Metabolic acidosis is a common complication in incident renal transplant recipients. Protracted acidosis may be associated with osteoporosis, inflammation, negative protein balance and malnutrition, and last but not least may cause renal dysfunction. Preliminary data indicate an increased prevalence of nephrocalcinosis in renal transplant biopsies of incident patients presenting with metabolic acidosis. The present study aims (1)evaluate the prevalence and type of renal tubular acidosis (RTA) in incident renal transplant recipients and to identify clinical correlates and (2) to find associations between RTA, nephrolithiasis and nephrocalcinosis
MP4OX is a novel oxygen therapeutic agent being developed as an ischemic rescue therapy to enhance perfusion and oxygenation of tissues at risk during hemorrhagic shock. MP4OX is a pegylated hemoglobin-based colloid. Due to its molecular size and unique oxygen dissociation characteristics, MP4OX targets delivery of oxygen to ischemic tissues. This study will evaluate the safety and efficacy of MP4OX treatment in trauma patients suffering from lactic acidosis due to severe hemorrhagic shock. The study hypothesis is that MP4OX will reverse the lactic acidosis by enhancing perfusion and oxygenation of ischemic tissues and thereby prevent and reduce the duration of organ failure and improve outcome in these patients.
In this study the investigators want to test the safety of D-lactate producing probiotics in babies from birth to 1 month of age. Previous data demonstrated no increase in urinary D-lactate in 4 month old infants supplemented with D-lactate producing probiotics. The primary purpose of this study is to evaluate the influence of D-lactate producing probiotics on D-lactate excretion in young infants during the neonatal period (days 0 - 28).
In this study we want to show that the choice of a balanced type fluid solution for the perioperative fluid management of patients receiving cadaveric renal transplantation results in less occurrence of intra- and postoperative hyperkalemia, and thus the need for postoperative dialysis. Additionally, we aim to determine whether the use of a balanced infusion solution leads to less occurrence of metabolic acidosis and electrolyte disorders than the use of isotonic saline. Furthermore we want to evaluate whether perioperative fluid management with balanced infusion solutions results in a higher frequency of primary graft function than with administration of isotonic saline. We will test the hypothesis that the use of "Elomel isoton"(Fresenius Kabi Austria GmbH) a balanced infusion solution will result in less occurrence of hyperkalemia and consequent post-transplant dialysis, less occurrence of metabolic acidosis, decreased incidence of electrolyte disorders and higher incidence of primary graft function when compared to isotonic saline for perioperative fluid management in patients receiving cadaveric renal transplantation.
MP4OX is a novel oxygen therapeutic agent specifically developed to perfuse and oxygenate tissue at risk for ischemia and hypoxia. MP4OX is a pegylated hemoglobin-based colloid and and as a result of its molecular size and unique oxygen dissociation characteristics, targets oxygen delivery to ischemic tissues by selectively off-loading oxygen in tissues predisposed to low oxygen tension. Sangart is currently evaluating MP4OX to reduce organ dysfunction and failure in trauma patients with lactic acidosis due to severe hemorrhagic shock.
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.
Acidosis (accumulation of acid in the body) may be an underrecognized problem in patients after renal transplantation. It may have consequences on physical performance due to negative effects on bone and muscle metabolism. Therefore, the purpose of this study is 1. to determine the status of physical capacity and bone structure in renal transplant patients with metabolic acidosis 2. to study the effect of substituting base equivalents (citrate) on acid/base status of renal transplant patients with acidosis 3. to compare the status of physical capacity and bone structure in renal transplant patients with metabolic acidosis before and after substitution with citrate
The objective of this study is to evaluate the effects of 'high' versus 'low' volume intraoperative fluid administration (Ringer Lactate, RL) on intra- and postoperative parameters, in obese patients undergoing laparoscopic bariatric surgery (i.e., gastric bypass), in order to establish evidence-based data for perioperative fluid management in this patient population. Based on their experience as well as several reports in the literature, the investigators hypothesized that a restrictive approach to intraoperative hydration will reduce the incidence of postoperative complications and the recovery time of gastrointestinal (GI) function, and shorten hospital stay.
