Suggested citation: Ronco R. Blood lactate as prognostic marker in critically ill children: a problem related to production or clearance? J Pediatr (Rio J). 2005;81:271-2. The temporal evolution of blood lactate levels has been widely used as a prognostic marker in critically ill patients, especially in the unstable phase. In the study published by Koliski et al.1 in this issue of Jornal de Ped...

lactate acid, skeletal muscle, mortality Lactic acid is a naturally occurring molecule with original detection falling into a category of lactic acid-producing bacterial organisms. However first detected in foods, its increased concentration in muscles of hunted animals was later linked with lactate acidosis origin. Physiologically, high rate of ATP hydrolysis, occurring during anaerobic glycol...

Changes in lactate kinetics as a function of exercise intensity have never been measured in an ectotherm. Continuous infusion of a tracer is necessary to quantify rates of lactate appearance (Ra) and disposal (Rd), but it requires double catheterization, which could interfere with swimming. Using rainbow trout, our goals were to: (1) determine the potential effects of catheters and blood sampli...

BACKGROUND Hyperlactatemia upon admission is a documented risk factor for mortality in critically ill adult patients. However, the predictive significance of a single lactate measurement at admission for mortality in the general population of critically ill children remains uncertain. This study evaluated the predictive value of blood lactate levels at admission and determined the cut-off value...

The goal of this study was to define the individual model characteristics lactic acid removal after 200m breaststroke competitive load in a female swimmer relation different pool lengths (25m vs. 50m). second methodological and referred presentation newly applied metrological procedures for Individual Lactate Recovery Profile modeling. Six races from season 2021/22 were selected, which athlete ...

Lactate has been shown to be an important oxidative fuel. We aimed to quantify the total lactate oxidation rate (Rox) and its direct vs. indirect (glucose that is gluconeogenically derived from lactate and subsequently oxidized) components (mg·kg(-1)·min(-1)) during rest and exercise in humans. We also investigated the effects of endurance training, exercise intensity, and blood lactate concent...

BACKGROUND Canine pyometra is a life-threatening disease common in countries where spaying of dogs is not routinely performed. The disease is associated with endotoxemia, sepsis, systemic inflammatory response syndrome (SIRS) and a 3-4% mortality rate. Blood lactate analysis is clinically valuable in predicting prognosis and survival, evaluating tissue perfusion and treatment response in human ...

The purpose of the present study was to compare heart rate (HR), blood lactate and training load between different CrossFit® workouts, with equalized total work volumes in men women. included 23 individuals (13 10 women) experienced training, who performed two workouts types (as many reps as possible (AMRAP) ‘for time’) but an volume. Measurements lactate, HR rating perceived exertion (RPE) wer...
