Accuracy and precision of hemoglobin point-of-care testing during major pediatric surgery


Spielmann, N; Mauch, J; Madjdpour, C; Schmugge, M; Weiss, M; Haas, T (2012). Accuracy and precision of hemoglobin point-of-care testing during major pediatric surgery. International journal of laboratory hematology, 34(1):86-90.

Abstract

Introduction:  The aim of the study was to compare accuracy and reproducibility of four point-of-care testing (POCT) devices (GEM(®) Premier 3000, ABL 800 flex, GEM(®) OPL(™) , HemoCue(®) B-Hemoglobin) for hemoglobin (Hb) analyzes as compared with the reference laboratory method (Sysmex XE 2100) in children undergoing major surgery. Methods:  Pediatric patients undergoing craniofacial, spine, hip, or cancer surgery were included. Blood samples for Hb testing were taken at several intraoperative time points and generally withdrawn from the arterial catheter, if accessible. Results:  A total of 256 blood samples were taken intraoperatively from 71 pediatric patients. All POCT devices showed very small bias (maximum -0.46 g/dL) to reference method as well as very good reproducibility (maximum coefficient of variation of 0.99%). However, in two cases (HemoCue), potential clinical relevant differences were observed beyond a range of 2 g/dL. Conclusion:  All POCT devices tested and operated by trained staff for hemoglobinometry showed reliable test results. They all allow for simple, fast, and precise bedside determination of hemoglobin concentration in the intraoperative setting.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
