Filter by:This study is to evaluate whether thiamine can increase oxygen consumption and lower lactate in patients who initially survive an in-hospital cardiac arrest. Patients who are successfully resuscitated after an in-hospital cardiac arrest and who are on mechanical ventilation in the intensive care unit will be enrolled, and will get either thiamine or placebo. Their oxygen consumption and lactate will be measured at serial time points and compared between groups. The investigators' hypothesis is that thiamine will help restore the body's ability to metabolize oxygen normally (aerobic metabolism), leading to an increase in oxygen consumption and a decrease in lactate.
VNI Versus is a clinical, prospective, randomized, cross over study, aiming to compare two mechanical ventilators during non-invasive ventilation for patient suffering from respiratory acidosis. This study will compare a dedicated ventilator for Non Invasive Ventilation (NIV) functioning with a turbine and with vented mask (exhalation by a calibrated leak) and a dedicated ventilator for Intensive Care Unit (ICU), functioning with non-vented masks and an exhalation valve. Patient will be randomized before the first NIV session lasting 2 hours. After a two hours wash-out, a second NIV treatment will be delivered with the other ventilator for duration of 2 hours. Arterial blood samples will be collected at the beginning and the end of each session of NIV. A transcutaneous captor of dioxide carbon pressure (PCO2) will also be used for patient monitoring.
The management goals of diabetic ketoacidosis (DKA) in the pediatric type 1 diabetes (T1DM) population are fluid and electrolyte repletion, insulin administration, and correction of acidosis in order to stabilize the patient. Traditionally, a rapid-acting insulin IV infusion is begun immediately and continued until the acidosis is corrected and hyperglycemia normalized. Once the acidosis is corrected, patients are able to be transitioned to a subcutaneous insulin regimen. The role that a subcutaneous long-acting insulin such as glargine has in the acute treatment of DKA has not been extensively studied. While giving glargine during the treatment of DKA is becoming more common place, few studies have examined the potential risks and benefits of its use. This study will investigate the effects of early administration of glargine during DKA in patients with newly diagnosed TIDM. The design of this study is a prospective, double-blind study of children ages 2-21 who are admitted to the hospital in DKA with a diagnosis of T1DM. The control group will receive all traditional methods of treatment for DKA, including a placebo subcutaneous injection. The study group will receive the same treatment, but will be supplemented with a subcutaneous glargine injection.
The objective of this study is to assess the effect of alkali administration on bicarbonate and potassium levels in patients with Sickle Cell Disease (SCD) and depressed serum bicarbonate levels. The study is a prospective non-blinded evaluation of tolerability and efficacy of alkali repletion with 4 weeks of observation and two sequential 4 week courses of escalating oral sodium bicarbonate treatment.
Hypothesis: STAN monitoring will reduce the number of interventions because of suspected fetal asphyxia and reduce the number of newborns with metabolic acidosis. Primary endpoint: 1) Frequency of metabolic acidosis in the two groups, defined by pH in umbilical cord artery < 7.05 and standard base excess <-10. Secondary endpoints: 1. Number of intervention (VE and caesarean section) in the two groups 2. Number of pH measurements in the two groups 3. Number of neonates admitted to the neonatal department because of suspected asphyxia in the two groups The aim of fetal surveillance is to identify those fetuses at risk for developing damage in newborn to term or long term damage caused by lack of oxygen during birth process. Approximately 1/10 of all cases of paralysis due to brain damage (cerebral palsy) is believed to be caused by lack of oxygen during birth. These can be avoided if the investigators intervene actively in the birth before damage occurs. CardioTocoGraphy (CTG = detection of fetal heart rate pattern and maternal uterine contractions via electrodes on the maternal abdomen and fetal scalp) is a widely used method of fetal surveillance. However, it can be difficult to interpret a CTG, and uncertainty in CTG interpretation may therefore lead to increase in the number of deliveries with vacuum suction and caesarean section. Interpretation of CTG can be improved by analyzing the acidity of a blood sample taken from the skin of the fetal scalp. Such a scalp pH analysis shows indirectly the fetus gets enough oxygen. Scalp pH measurement requires expertise and requires repeated measurements if the abnormal heart rate pattern persists. This method is the normal routine at the maternity ward at Hvidovre Hospital / Roskilde County Hospital. The problem seems to be partially alleviated by using a newly developed method for fetal surveillance called STAN (ST analysis). By STAN continuously recorded both CTG and fetal ECG (electrocardiography = recording of the electrical heart activity). Simultaneously analyzes a portion of the fetal ECG, namely ST-part because hypoxia leads to changes in it. The technique is easy to use, since it only requires one electrode on the fetal scalp that is placed in the same way as in ordinary CTG registration.
Background: Very few drugs exist that treat hyperammonemia, specifically PA and MMA. Diet restrictions and alternate pathway agents are the current primary treatments, but they frequently fail to prohibit brain damage. Orthotopic liver transplantation cures the hyperammonemia of urea cycle disorders, but organ availability is limited and the procedure is highly invasive and requires life-long immunosuppression. A drug that could repair or stimulate a dysfunctional urea cycle such as this would have several advantages over current therapy. A drug called N-carbamyl-L-glutamate, Carglumic acid (NCG or Carbaglu)has recently been found to be virtually curative of another urea cycle defect called NAGS deficiency. In this disorder, treatment with NCG alone normalizes ureagenesis, blood ammonia and glutamine levels, allows normal protein tolerance and restores health. Knowledge from this study is being applied to acquired hyperammonemia, specifically in patients with propionic PA and MMA, to try and improve neurodevelopmental outcomes by improving the hyperammonemia. Aims: The overall objective of this project is to determine whether treatment of acute hyperammonemia with Carglumic acid in propionic acidemia (PA), methylmalonic acidemia (MMA) changes the long-term outcome of disease and to determine if it is effective in restoring urine ammonia levels to normal levels.
The purpose of this study is to investigate whether entecavir treatment increases the incidence of lactic acidosis compared to another nucleoside/nucleotide reverse transcriptase inhibitors (NRTI), lamivudine, and/or no NRTI treatment, in patients with cirrhosis or hepatic failure whose Model for End stage Liver Disease (MELD) scores are over 18.
This study involved the medical record review of resuscitation records for all severely-injured trauma patients requiring emergent surgical intervention and significant acidosis from 2005 through 2009.
The purpose of this pilot study is to evaluate whether administration of nitric oxide (NO)gas by oxygen hood at 20 ppm significantly increases PaO2, as compared to placebo gas (oxygen), within one hour of initiation and with no significant adverse effects.
