    Plasma ionized calcium during open-heart surgery (1985)

    Notes: Plasma ionized calcium has been measured in eighteen patients undergoing open heart surgery. No change in ionized calcium concentration was found during the period of cardiopulmonary bypass. In the early postbypass period, a wide range of ionized calcium concentrations was found, but this did not obviously affect myocardial performance. Factors influencing the ionized calcium concentration under these circumstances are discussed.

    Choice of calcium salt (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 39 (1984), S. 0

    Notes: Equimolar quantities of calcium chloride and calcium gluconate produced similar changes in plasma ionised calcium concentration when injected intravenously into anaesthetised ferrets or when added to human blood in vitro. In vivo changes were followed with a calcium electrode positioned in the animal's aorta, and this showed that the ionisation of calcium gluconate on its first pass through the circulation is as great as that of calcium chloride. This does not support the common suggestion that calcium chloride is preferable to calcium gluconate because of its greater ionisation.

    Notes: Abstract Objective: To compare the results of cardiac output measurements obtained by lithium dilution and transpulmonary thermodilution in paediatric patients. Design: A prospective study.¶Setting: Paediatric intensive care unit in a university teaching hospital.¶Patients: Twenty patients (age 5 days–9 years; weight 2.6–28.2 kg) were studied.¶Interventions: Between two and four comparisons of lithium dilution cardiac output (LiDCO) and transpulmonary thermodilution (TPCO) were made in each patient.¶Measurements and results: Results from three patients were excluded: in one patient there was an unsuspected right-to-left shunt, in two patients there was a problem with blood sampling through the lithium sensor. There were 48 comparisons of LiDCO and TPCO in the remaining 17 patients over a range of 0.4–6 l/min. The mean of the differences (LiDCO–TPCO) was –0.1 ± 0.3 (SD) l/min. Linear regression analysis gave LiDCO = 0.11 + 0.90 × TPCO l/min (r 2 = 0.96). There were no adverse effects in any patient.¶Conclusions: These results suggest that the LiDCO method can be used to provide safe and accurate measurement of cardiac output in paediatric patients. The method is simple and quick to perform, requiring only arterial and venous catheters, which will already have been inserted for other reasons in these patients.
