Comparison of bedside and laboratory blood glucose estimations in critically ill children with shock

Abstract

Capillary blood glucose estimation in children with shock was similar to the laboratory measurement in the midranges of glucose values.

Blood glucose concentrations in prehospital trauma patients with traumatic shock

“…In patients with haemodynamic shock it may be more difficult to obtain venous blood for glucose concentration measurement. In venous blood, measured blood glucose concentration may be lower than in capillary blood, [48][49][50] but Ramachandran et al 51 did not find significant differences between venous and capillary blood glucose concentrations in children with shock. In contrast, Pulzi Ju ´nior et al 52 found higher blood glucose concentrations in capillary blood from patients in shock who received noradrenaline (norepinephrine) or had diminished tissue perfusion.…”

Association between Blood Glucose and cardiac Rhythms during pre-hospital care of Trauma Patients – a retrospective Analysis

“…The literature shows contradictory conclusions regarding the impact of venous vs. capillary blood glucose measurements, the existence of shock or the administration of catecholamines. In addition, the limited precision of point-of-care devices is well-known, especially when blood glucose concentrations are extremely high or low [ 63 – 65 ]. In this study, measurements of blood glucose concentration were conducted while establishing the initial iv access and before drug administration, for which reason the influence of external catecholamines (e.g.…”

Infrastructure and Organization of Adult Intensive Care Units in Resource-Limited Settings

“…Although our literature search did not reveal a randomized controlled trial showing that measurement of blood glucose is associated with improved outcome, it is sensible to assume that detection of dysglycemic episodes is associated with improved care. While studies from resource-limited settings suggest that results of point-of-care methods to measure blood glucose levels are closely correlated with those of laboratory measurements [188,189], some studies from resource-rich settings have highlighted inaccuracies of point-of-care devices in lower blood glucose ranges [190]. A recent international multicenter study, however, demonstrated that bedside blood glucose monitoring systems were acceptable for use in critically ill patient settings when compared to a central laboratory reference method [191].…”

“…Although cassette-based blood gas analyzers show a comparable accuracy to traditional blood gas analyzers [210] and require less technical maintenance, they are associated with much higher costs, particularly when large amounts of blood samples are analyzed. Separate point-of-care devices measuring blood lactate levels have been suggested as cheaper alternatives to blood gas analyzers in resourcelimited settings [189,211]. Moreover, availability of blood gas analyzers is severely limited [212], and contemporary evidence from resource-rich and resource-limited settings suggest that arterial blood gas measurement may not be necessary to diagnose and to improve outcomes for ARDS [137,213].…”
