In a recent article in Critical Care, Tapia and colleagues evaluated the relationship between exogenous lactate clearance and liver perfusion in a short-term model of endotoxemic shock [1]. The authors concluded that the very low portal-hepatic vein lactate gradient was indicative of the inability of the liver to metabolize the increased lactate load. Although we believe that the authors addres...

OBJECTIVE The determination of postoperative course after cardiac surgery has always been a challenging issue. It is more sophisticated in the pediatric age group. The aim of this investigation was to identify whether increased concentrations of lactate in arterial blood has a predictive value for postoperative morbidity and mortality after heart surgery. METHODS From May 2002 to June 2003, 6...

Lactate derived from glucose can serve as an energy source in the brain. However, it is not certain how much lactate, directly taken from the blood circulation, may replace glucose as an energy source. This study aimed to estimate the uptake, release, and utilization of lactate entering the brain from the blood circulation. The change in cerebral venous-arterial glucose and lactate differences ...

Increased cerebral lactate levels are a well-known aspect of the sequelae of the metabolic derangements that follow cerebral ischemia. A new technique has recently become available to sample cerebral venous blood from the superior sagittal sinus on a long-term basis in conscious rats. We report the applicability of this method to assess serial biochemical responses to brain injury. Serum sample...

To assess the effects of sodium nitroprusside (5-10 mug/min) on total and regional cardiac performance, energetics, and lactate metabolism during acute ischemia, studies were performed in 21 open-chest dogs. For studies of regional function and metabolism, length gauges were sutured to the epicardial surface and an epicardial vein adjacent to the artery to be occluded was cannulated. Following ...

OBJECTIVE To define whether increases in gastric intramural tissue CO2 and H+ increase during experimentally induced peritonitis with circulatory shock as they do under conditions of hemorrhagic shock and cardiac arrest. DESIGN AND SETTING Peritonitis was induced in Sprague-Dawley rats by cecal ligation and fecal spillage. MEASUREMENTS AND RESULTS Over an interval of 260 +/- 20 min in 5 ani...

Lactate and pyruvate concentrations and acid-base balance in cerebrospinal fluid (CSF) and arterial blood were determined in patients with intracranial hemorrhages (28 subarachnoid hemorrhages and 15 intracerebral hemorrhages). A greater increase in CSF lactate and lactate-pyruvate ratio (L/P ratio) was observed in patients with impairment of consciousness, focal neurological deficits, poor pro...

Lactate has been thoroughly studied and found useful for stratification of patients with sepsis, in the Intensive Care Unit, and trauma care. However, little is known about lactate as a risk-stratification marker in the Medical Emergency Team- (MET-) call setting. We aimed to determine whether the arterial blood lactate level at the time of a MET-call is associated with increased 30-day mortali...

1. In closed-chest dogs anaesthetized with trichlorethylene, the inhalation of carbon dioxide sufficient to increase the arterial P(CO2) from 40 to about 100 mm Hg, increased myocardial blood flow (measured using a (133)Xe clearance technique) and right atrial pressure. There were no consistent changes in mean arterial blood pressure, heart rate or cardiac output.2. The effect of hypercapnia on...

BACKGROUND Point-of-care (POC) testing is highly useful when treating critically ill patients. In case of difficult vascular access, the intraosseous (IO) route is commonly used, and blood is aspirated to confirm the correct position of the IO-needle. Thus, IO blood samples could be easily accessed for POC analyses in emergency situations. The aim of this study was to determine whether IO value...
