Electronic fetal monitoring (EFM) during labor has been performed for 40 years. However, the specificity in diagnosing asphyxia is still insufficient. The combination of EFM and fetal scalp-blood sampling was introduced shortly after the introduction of EFM.  Although this monitoring ensures a better sensitivity and...

Neonates are subject to more preanalytical influences than any other population group. Many of these are related to the maturity of the infant and its adaptation to extra-uterine life. The necessary need for capillary blood collection and processing of small quantities of blood introduce additional preanalytical...

How do small labs cope with the demands of modern quality assurance? In this interview, Ruth Lock, head of the laboratory of the Anesthesiology and Intensive Care Dept. of the Copenhagen County Hospital in Glostrup, Denmark, tells how her lab keeps up with demands with the help of training and quality control.

While analytical quality standards seem well established, there has been a paucity in the development of such standards for the preanalytical phase.  Technical recommendations regarding sampling, transport, and identification have been developed in national (NCCLS, DIN) and international (IFCC, ISO) consensus...

The results of laboratory tests are used in many clinical settings. In the main, results obtained in point-of-care testing (POCT) are used either in monitoring or in diagnosis. Analytical quality does affect outcomes in these clinical situations. Numerical estimates of the quality required for laboratory tests to...

An altitude of 5,000 meters above sea level or just above is just about what humans can bear - be it during an acute ascent or for permanent living. This study describes how bodily functions of crucial importance to survival at high altitude adjust after abrupt exposure to severe hypoxia.

Providing continuous technical support and reliable test data collection for point-of-care blood gas testing is a difficult task for many laboratories.  Here we describe how the implementation of an integrated instrument control and data management system for point-of-care blood gas testing has streamlined these...

The pro-con debate on the advisability of introducing POCT deals with the likely clinical benefits but – to an even higher degree – with the economic aspects. We discuss various models for determining the costs, and some caveats.

Measurement of transcutaneous oxygen tension (tcpO₂) has gained worldwide acceptance as a simple and effective method of evaluating cutaneous blood flow in settings where skin viability and the adequacy of skin blood flow are of major concern. An example of such a setting is the non-invasive vascular laboratory at...

Assessment of tcpO₂ before and during hyperbaric oxygen treatment predicts the chance for a successful outcome.
