Serum ionised calcium in birth asphyxia

Serum ionised calcium concentration: measurement versus calculation.

Four hundred and eighteen measurements of serum ionised calcium, total calcium, and protein concentrations were made from 47 normal volunteers, 104 patients with chronic renal failure (33 being treated conservatively and 71 with regular haemodialysis), and 83 renal transplant recipients. The serum ionised calcium concentration was measured with an Orion SS-20 meter and calculated from the total...

Serum Liver Enzyme Pattern in Birth Asphyxia Associated Liver Injury

PURPOSE To study temporal pattern of serum liver enzymes levels in newborns with hepatic injury associated with birth asphyxia (BA). METHODS Singleton term newborns with BA and ≤72 hours of age admitted to neonatal intensive care unit were prospectively enrolled. Term newborns with physiological jaundice and without BA were studied as controls. Serum liver enzymes were measured at <24 hours, ...

Correlation between serum ionised calcium and serum albumin concentrations in two hospital populations.

One quarter of 172 patients from two hospitals with no obvious disturbances of calcium homeostasis and with total serum calcium concentrations that were normal after adjustment for albumin concentration had low serum ionised calcium concentrations. The low values were not due to changes in pH but were associated with hypoalbuminaemia. Significant positive regressions of ionised calcium on album...

Population based study on serum ionised calcium, serum parathyroid hormone, and blood pressure. The Tromsø study.

OBJECTIVE To study associations between serum ionised calcium, serum parathyroid hormone (PTH) and blood pressure. DESIGN A population based, cross-sectional study was used. METHODS Blood pressure, body mass index, serum ionised calcium and serum PTH were measured in 460 males and 486 females in the Tromso study in 1994/1995. None were on medication for hypertension. The data were analysed ...
