Comparison of pre-filter and post-filter ionised calcium monitoring in continuous veno-venous hemodiafiltration (CVVHD-F) with citrate anti-coagulation
BACKGROUND It is widespread practice during citrate anticoagulated renal replacement therapy to monitor circuit ionised calcium (iCa2+) to evaluate the effectiveness of anticoagulation. Whether the optimal site to sample the blood path is before or after the haemofilter is a common question. METHODS Using a prospectively collected observational dataset from intensive care patients receiving p...
متن کاملMeasurement of ionised calcium concentration in neonates.
Whole blood ionised calcium concentration was measured simultaneously in capillary and arterial blood from neonates being nursed on an intensive care unit using an ion selective electrode. The mean arterio-capillary difference was -0.027 mmol/l (95% confidence intervals -0.041 to -0.012 mmol/l) and the limits of agreement between the two measurements were 0.034 and -0.088 mmol/l. Measurement of...
متن کاملSerum 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...
متن کاملElimination of meropenem during continuous veno-venous haemofiltration and haemodiafiltration in patients with acute renal failure.
Meropenem elimination was studied in six patients with acute renal failure on continuous venovenous haemofiltration (CVVH) or continuous veno-venous haemodiafiltration (CVVHDF) 1 L/h and 2 L/h for 12 h. Meropenem 1 g was given iv over three dialysis periods, and plasma, ultrafiltrate/dialysate and urine concentrations of meropenem were determined. The half-life of meropenem was significantly lo...
متن کاملThe effect of circuit "down-time" on uraemic control during continuous veno-venous haemofiltration.
OBJECTIVE The term continuous veno-venous haemofiltration (CVVH) suggests a treatment without interruption. However, interruptions do occur and the duration of the haemofiltration circuit "down-time" may influence uraemic control. We conducted a prospective study to ascertain the percentage of operative "down-time" for CVVH in our intensive care unit and to test the hypothesis that it significa...
