Lactic acidosis, the most common kind of metabolic acidosis, is characterized by reduced blood pH (usually <7.25) in association with marked increase in blood lactate (usually >5.0 mmol/L). Lactic acidosis has many possible causes but two broad etiological classes have been defined: type A (hypoxic) lactic acidosis and ...

Sampling capillary blood from the fetal scalp during labor of pregnancy, in order to determine its pH, was introduced to obstetric care in the late 1960s.  Despite current skepticism surrounding its utility, most notably in the US, fetal-scalp blood sampling (FSBS) is still considered a useful fetal monitoring test...

The pH, base excess and pCO₂ (acid-base status) of arterial blood flowing through the umbilical cord provides valuable objective evidence of the metabolic condition of neonates at the moment of birth; a notion that has assured a role for the blood gas analyzer in hospital delivery suites in cases of suspected fetal...

Metformin is a widely prescribed oral antihyperglycemic drug for the long-term treatment of type 2 diabetes. It is considered a first-line drug treatment for those diabetic patients whose blood glucose remains uncontrolled by dietary and other lifestyle interventions. In addition to this established use, metformin has ...

In high-level athletes preparation, using point-of-care testing (POCT) in sports-specific environments, we tried to define and control the levels of exercise intensities (“energy training zones”), to quantify metabolic functionality (sports-specific energy sources, baseline conditions, functional costs of exercise in...

Blood lactate concentration, a parameter often available at the point of care on blood gas analyzers, is useful for assessment of global tissue oxygenation among acutely/critically ill patients. The ”gold standard” sample for this assessment, as for blood gas analysis, is arterial blood.  Sampling of venous blood is...

In a regional top-management decision, our laboratory was given the mission to control and quality assure all POCT activities in a regional network of 10 hospitals with emergency units. Based on previous work, new region-wide recommendations, procurements,  IT connectivity, services, training, accreditation (ISO...

Many authors contend that drawing of umbilical ABGs is a simple method to evaluate the condition of the neonate and ideally would be routinely done for all newborns [13]. Other authors disagree. Appropriate general principles guide clinicians when drawing and interpreting ABGs for all patients. The special needs of...

BACKGROUND: Hospitals in countries with public health systems have recently adopted organizational changes to improve efficiency and resource allocation, and reducing inappropriate hospitalizations has been established as an important goal, as well as avoiding or buffering overcrowding in Emergency Departments. AIMS: ...

Calcium is an essential mineral required for numerous biological functions. In circulation, calcium is found in three different fractions, anion-bound, protein-bound and free or ”ionized”. The amount of calcium in each of these fractions is dependent on the concentration of hydrogen ions, anions and plasma proteins....
