ABSTRACT
Background: In the absence of uniform European regulations, there have been many differences in the training of perfusionists across Europe. Furthermore, there has been no uniform or single European accreditation of the profession. One of the objectives of The European Board of Cardiovascular Perfusion (EBCP) is to standardise and monitor training of perfusionists across Europe whilst offering support in accordance with national regulations. This goal is particularly imminent as there have been numerous newly founded National perfusion societies, particularly from Eastern European countries, which are now established members of EBCP.Purpose: In this article, we provide an updated overview or 'snapshot' of current European perfusion training programs that were accessible in 2022. Nationally acquired data refers to 2022 unless stated otherwise. The last overview of Perfusion education in Europe was reported over 15 years ago including 20 countries.Research Design: For this report thirty-two national EBCP delegates plus representatives from Austria were contacted at the beginning of 2023 to complete a pro forma questionnaire about their national perfusion training programmes. The data has been summarized in this article and five additional derived parameters were calculated.Results: We received responses from 31 countries, providing specific national training characteristics which are summarized, listed and benchmarked by country in this article.Conclusion: There have been several national and supranational initiatives towards the recognition of perfusion as a profession in Europe, however so far without success for the majority of countries. For this reason, it remains essential for EBCP, as the only European professional perfusionist body, to define education standards and competencies for perfusionists and to monitor training by accreditation of dedicated perfusion schools across Europe.
ABSTRACT
BACKGROUND: High volumes of haemofiltration are used in septic patients to control systemic inflammation and improve patient outcomes. We aimed to clarify if extended intermittent high volume online haemodiafiltration (HVHDF) influences patient haemodynamics and cytokines profile and/or has effect upon sublingual microcirculation in critically ill septic shock patients. METHODS: Main haemodynamic and clinical variables and concentrations of cytokines were evaluated before and after HVHDF in 19 patients with septic shock requiring renal replacement therapy due to acute kidney injury. Sublingual microcirculation was assessed in 9 patients. RESULTS: The mean (SD) time of HVHDF was 9.4 (1.8) hours. The median convective volume was 123 mL/kg/h. The mean (SD) dose of norepinephrine required to maintain mean arterial pressure at the target range of 70-80 mmHg decreased from 0.40 (0.43) µg/kg/min to 0.28 (0.33) µg/kg/min (p = 0.009). No significant changes in the measured cytokines or microcirculatory parameters were observed before and after HVHDF. CONCLUSIONS: The single-centre study suggests that extended HVHDF results in decrease of norepinephrine requirement in patients with septic shock. Haemodynamic improvement was not associated with decrease in circulating cytokine levels, and sublingual microcirculation was well preserved.

PURPOSE: The purpose of the study is to clarify whether increased intra-abdominal pressure (IAP) is associated with sublingual microcirculatory alterations in intensive care patients. METHODS: Fifteen adult, mechanically ventilated patients were included if their IAP was at least 12 mm Hg for at least 12 hours within the first 3 days after admission to the intensive care unit. Sublingual sidestream dark field (SDF) images were recorded twice a day for 7 days. RESULTS: Median (interquartile range) IAP at inclusion was 14.5 (12.5-16.0) mm Hg. The total vascular density of small vessels at the sublingual area was 13.1 (10.6-14.3) per square millimeter at baseline; the proportion of perfused vessels, 78.9% (69.6%-86.2%); and perfused vessels density, 12.4 (10.8-13.8) per square millimeter. The calculated indices suggested relatively good blood flow in the capillaries, with a De Backer score of 9.0 (8.3-10.2) and a microvascular blood flow of 3.0 (2.9-3.0). Blood flow heterogeneity index was 0.3 (0.1-0.5) at study entry. Despite that IAP, vasopressors dose, and arterial lactate decreased significantly over time, no significant changes were observed in sublingual microvascular density or blood flow. Weak correlations of microvascular blood flow (positive) and heterogeneity index (negative) were detected with both mean arterial pressure and abdominal perfusion pressure. CONCLUSIONS: Neither grade I or II intra-abdominal hypertension (IAP from 12 to 18 mm Hg) is associated with significant changes of sublingual microcirculation in intensive care patients. Correlation analysis indicates better microvascular blood flow at higher mean arterial pressure and abdominal perfusion pressure levels.
