Comparative Study
Kinetic of procalcitonin in the early postoperative course following heart transplantation.
It was the aim of the study to determine the kinetics of procalcitonin (PCT) levels following heart transplantation (HTx) and to investigate the prognostic suitability of postoperative changes in PCT levels for patients' outcome. ⋯ PCT levels have been consistently low (<10 ng/mL) in patients with an uneventful course, but more frequently increased in patients with postoperative complications and even associated with an increased mortality early postoperatively when values exceed 80 ng/mL. As a clinical consequence, PCT levels in the first few days following cardiac transplantation can help to identify patients at risk, when concentrations exceed the "normal" posttransplant range.

Real-time readings of the regional oxygen saturation (rSO(2)) using near-infrared spectroscopy (NIRS) during the aortic arch surgery can provide an early detection of perfusion or oxygenation abnormalities. ⋯ Continuous monitorization of the cerebral O(2) saturation during aortic arch surgery in adults and infants is a feasible technique to control an adequate cannula positioning and to optimize clinical outcomes avoiding neurological complications related to cerebral malperfusion.
