Transcutaneous monitoring of pO2 and pCO2 in neonates - a blessing or a burden?
Monitoring of blood gases is essential in neonatal intensive care. Traditionally arterial samples have been considered the gold standard, but in critically ill neonates physiological changes can happen within minutes to a degree endangering the newborn.
Clinicians can therefore not rely solely on intermittent...

Useful tips to avoid preanalytical errors in blood gas testing: electrolytes
Preanalytical errors are said to be the reason for up to 75 % [1] of all errors in laboratory medicine. The diagnostic consequences depend on the magnitude of the preanalytical error.
In worst case, these errors may lead to mistreatment of patients; in all cases, these errors are an extra workload for the hospital...

Pulse oximetry vs. transcutaneous monitoring in neonates: practical aspects
Non-invasive monitoring of oxygenation has become a standard procedure in neonatal critical care. Both transcutaneous pO2 (tcpO2) monitors and pulse oximeters involve methodological and practical issues that should be known to those using these devices in infants.
tcpO2 measurements are influenced by skin thickness, ...

Principles and problems of blood glucose measurement
Although blood glucose measurement is commonly performed, the use of a whole-blood sample introduces complications and compromise in terms of the assay principle, the method of calibration and the expression of results.
Most point-of-care systems are calibrated against a method chosen by the manufacturer for...

Increased blood lactate levels: a marker of...?
Since Meakins in 1927 described the relationship between increased blood lactate levels and the presence of oxygen debt (tissue hypoxia) in patients with circulatory shock [1], lactate levels have been used to diagnose and monitor the treatment of these patients.
However, as lactate is a normal (end) product of...
