Because biological data are instrument-dependent and because technology has evolved over the last two decades, the published capillary blood reference values for blood gases, lactate, ionized calcium (iCa) and glucose may not reflect the present day situation. Elsevier Science While drawing venous sample make sure that no tourniquet is applied, artery is not compressed and sample is drawn against the flow of blood towards heart. Capillary Blood Gas Sampling for Neonatal & Pediatric Patients . Literature on capillary blood biochemical parameters in normal neonates being limited, comparison with other studies is difficult. All had APGAR scores Exclusion criteria included: hyperbilirubinenia requiring phototherapy before 48 h of age, admission to the NICU or intermediate care unit, parents understanding neither French nor English or absence of informed consent form signed by the parents.After having warmed the heel, free-flowing capillary blood samples were collected at 48 ± 12 of life in 125 Table revised by the author for publication on bloodgas.orgWe report reference values for 118 to 122 healthy term newborn babies between 36 and 60 h of age. adult hemoglobin at normal temperature and blood pH. January 2006
In general, normal pathology values are readily available for healthy term infants. At a PaO 2 of 90 mmHg, 95 percent of hemo-globin is saturated with oxygen. 2019 Mar;169(3-4):87-92. doi: 10.1007/s10354-018-0649-8. Because biological data are instrument-dependent and because technology has evolved over the last two decades, the published capillary blood reference values for blood gases, lactate, ionized calcium (iCa) and glucose may not reflect the present day situation.

Literature on capillary blood biochemical parameters in normal neonates being limited, comparison with other studies is difficult. Babies are not small adults!
Since there was no gender effect, all data were pooled.We use cookies to help provide and enhance our service and tailor content and ads. As (extreme) prematurity is a pathological condition in itself, be cautious when using the concept of ‘normal’. The authors wish to thank M Daniel Legault, Central laboratory coordinator and the Central laboratory technical staff for their precious help. values of capillary blood gas variables are presented in Table 1. taken not to include any air bubble in the capillary. This work was partially funded by the Fondation de l’Hôpital Ste-Justine through an operating grant for the evaluation of technology.May contain information that is not supported by performance and intended use claims of Radiometer's products.

Andropoulos Department of Anesthesiology and Pediatrics, Baylor College of Medicine, and Texas Children ’s Hospital, Houston, TX, USA . Whether reliable blood glucose concentration reference values in neonates are warranted is matter of discussion, as it is influenced by the timing of blood collection after the last feeding and by the type and source of milk (colostrum or formula). PO2: The dissolved oxygen in the blood. This smartphone app focuses on the preanalytical phase of blood gas testing and what operators can do to avoid errors. TABLE 1: Pediatric references for blood capillary pH, pCO 2, pO 2, hemoglobin, lactate, glucose and ionized calcium Using these three values, as well as known factors such as body temperature and normal hemoglobin values, it is possible to calculate a variety of additional numbers. One hundred twenty-six term neonates (39.6 ± 1.2 weeks of gestation) were included in the study. These are the values typically measured or calculated in a blood gas: pH: How acidic or basic the blood is. However, the arterial pH, The mean capillary lactate concentration observed in this study differs only by 0.1 mmol/L from those of Fauchère et al. Presented by Ellis Jacobs, PhD, Assoc.
On the contrary, the mean whole blood lactate concentration observed in this study (2.6 mmol/L) is higher than that observed by Nielsen Measurement of iCa has benefited from major technical refinements and is now reliable. Hence, we report such values for healthy term neonates at 48 ± 12 h of life.The Institution Ethics Review Board for Research on Human Subjects has accepted the protocol. Such an adaptation phenomenon has also been exemplified for the thyroid axis as well as for vitamins A, E and D [7–10]. Arteriolization of the capillary bed yields pH and pCO2 comparabe to arterial blood.
