BACKGROUND: Laboratory test in transport is a critical component of patient care, and capillary blood is a preferred sample type particularly in children. This study evaluated the performance of capillary blood testing on the epoc Point of Care Blood Analysis System (Alere Inc). METHODS: Ten fresh venous blood samples was tested on the epoc system under the capillary mode. Correlation with GEM 4000 (Instrumentation Laboratory) was examined for Na+, K+, Cl-, Ca2+, glucose, lactate, hematocrit, hemoglobin, pO2, pCO2, and pH, and correlation with serum tested on Vitros 5600 (Ortho Clinical Diagnostics) was examined for creatinine...

Background: Blood lactate is a strong predictor of mortality, and repeated blood lactate assays are recommended during surgery in high-risk patients. We hypothesized that the use of intravascular microdialysis incorporated in a central venous catheter would be interchangeable with the reference blood gas technique to monitor changes in blood lactate. Methods: Microdialysis and central venous blood lactate measurements were recorded simultaneously in high-risk cardiac surgical patients...

INTRODUCTION: Bispectral index (BIS) and monitoring of end-tidal concentration may be associated with a reduction in the incidence of awareness during volatile-based general anaesthesia. An analogue of end-tidal concentration during cardiopulmonary bypass (CPB) is measuring exhausted isoflurane concentration from the oxygenator as an estimate to blood and, so, brain concentration. The aim of this study was to determine the relationships between oxygenator exhaust and blood concentrations of isoflurane and the BIS score during CPB when administering isoflurane into the sweep gas supply to the oxygenator...

A 37-year-old hemodialysis patient appeared with unusual somnolence during 2 successive hemodialysis sessions. Blood gas analysis revealed hypercapnic respiratory failure and spirometry restrictive lung disease. After exclusion of other causes of restrictive lung disease with chest CT-scan and cerebrum MRI, electrophysiological study revealed myopathy. Because besides lordosis and limb-girdle gait the patient was ambulant the possibility of late-onset Pompe's disease was set and confirmed with evaluation of α-glucosidase activity and genetic analysis...

Ischemia modified albumin (IMA) is a marker that has been determined to be elevated in hypoxic conditions. This study aimed to investigate the relationships between serum IMA and blood gas parameters (BGPs) and evaluate whether IMA can be used as a parameter clinically in terms of reflecting tissue hypoxia in ventilator management. BGPs and serum IMA level were measured in blood samples drawn simultaneously from patients. Mean serum IMA levels, mean pCO2, mean pO2, and lactate levels were 82.56 ± 25.47 ng/mL, 47...

A 52-year-old Japanese male professional diver was referred to our hospital for decompression illness (DCI). After 1 h of diving operation at 20 m below sea level, he complained of dyspnea, chest pain, and abdominal pain. He dove again, intending to ease the symptoms, but the symptoms were never relieved. He dove for a total of 4 h. No neurological abnormalities were observed. Computed tomography images revealed portal venous gas and mesenteric venous gas, in addition to bubbles in the femoral veins, pelvis, lumbar canal, intracranial sinuses, and joints...

Interstitial lung disease (ILD) represents a collection of lung disorders with a lethal trajectory with few therapeutic options with the exception of lung transplantation. Various extracorporeal membrane oxygenation (ECMO) configurations have been used for bridge to transplant (BTT), yet no optimal configuration has been clearly demonstrated. Using a cardiopulmonary simulation, we assessed different ECMO configurations for patients with end-stage ILD to assess the physiologic deficits and help guide the development of new long-term pulmonary support devices...

BACKGROUND: Increasing numbers of patients with obstructive lung diseases need anesthesia for surgery. These conditions are associated with pulmonary ventilation/perfusion (VA/Q) mismatch affecting kinetics of volatile anesthetics. Pure shunt might delay uptake of less soluble anesthetic agents but other forms of VA/Q scatter have not yet been examined. Volatile anesthetics with higher blood solubility would be less affected by VA/Q mismatch. We therefore compared uptake and elimination of higher soluble isoflurane and less soluble desflurane in a piglet model...

Many of our medical procedures are conditioned by beliefs or experiences by our mentors, which we pass on to the younger, for example: gradually emptying a full bladder to avoid hypotension or haemorrhage, hydrating the alcoholic so that the blood alcohol level decreases faster, always obtaining an arterial blood gas instead of a venous one and not injecting iodinated intravenous contrast in patients allergic to shellfish.

The steady state concept implies that the oxygen flow is invariant and equal at each level along the respiratory system. The same is the case with the carbon dioxide flow. This condition has several physiological consequences, which are analysed. First, we briefly discuss the mechanical efficiency of exercise and the energy cost of human locomotion, as well as the roles played by aerodynamic work and frictional work. Then we analyse the equations describing the oxygen flow in lungs and in blood, the effects of ventilation and of the ventilation - perfusion inequality, and the interaction between diffusion and perfusion in the lungs...

Severe hypertriglyceridemia is a known, but uncommon complication of diabetic ketoacidosis. We discuss the case of a 23-year-old, previously healthy, woman who initially presented to the emergency department with abdominal pain. Grossly lipemic serum due to extremely high triglyceride (38.6 mmol/L) and cholesterol (23.2 mmol/L) levels were observed with a high blood glucose (23 mmol/L) and a low pH of 7.06 on a venous blood gas. She was treated successfully with fluids and insulin and had no sequale of pancreatitis or cerebral edema...
