The use of cardiopulmonary bypass (CPB) during coronary artery bypass graft surgery (CABG) is associated with a systemic inflammatory response, resulting in altered microcirculation. The aim of this study was to evaluate whether beating heart surgery can preserve the microcirculation. ⋯ While the results do not show a marked preservation of the microcirculation during and after OPCABG compared to ONCABG, they coincide with the body temperature fluctuations of each group during and after surgery. Our work suggests that active warming could impact the microcirculation parameters.

The use of extracorporeal life support (ECLS) in cardiopulmonary resuscitation (CPR; ECPR) has been repeatedly published as non-randomized studies, mainly case series and case reports. The aim of this article is to support physicians, perfusionists, nurses and extracorporeal membrane oxygenation (ECMO) specialists who regularly perform ECPR or are willing to start an ECPR program by establishing standards for safe and efficient ECPR procedures. This article represents the experience and recommendations of physicians who provide ECPR routinely. ⋯ The successful performance of ECLS cannulation during CPR is a life-saving measure and has been associated with improved outcome (including neurological outcome) after CPR. We summarize the general structure of an ECLS team and describe the cannulation procedure and the approaches for post-resuscitation care. The differences in hospital organizations and their regulations may result in variations of this model.

Despite advances in surgery and intensive care, mortality in acute mesenteric ischemia remains between 50% and 90%. In this study, we evaluated factors affecting mortality in acute arterial mesenteric ischemia. ⋯ High red cell distribution width and gamma glutamyl transpeptidase levels and anti-coagulant use are factors affecting mortality in arterial acute mesenteric ischemia. The assessment of these variables could help predict the extent of arterial acute mesenteric ischemia and the mortality associated with it.

Multicenter Study Comparative Study Clinical Trial Observational Study
Prevalence of preoperative anaemia in patients having first-time cardiac surgery and its impact on clinical outcome. A retrospective observational study.
The prevalence of anaemia is increasing globally. It has a close association with perioperative blood transfusion which, in turn, results in an increased risk of postoperative complications. Undesirable effects are not only limited to short-term, but also have long-term implications. ⋯ Anaemia was significantly associated with the development of new infection (14 (7%) vs. 15 (2.9%), p-value 0.0193, RR (CI 95%) 2.389 (1.175-4.859)), prolonged ventilation time (47.01 hours vs. 23.59 hours, p-value 0.0076) and prolonged intensive care unit (ICU) stay (80.23 hours vs. 50.27, p-value 0.0011). Preoperative anaemia is highly prevalent and showed a clear link with significantly higher transfusion rates and postoperative morbidity. It is vital that a preoperative management plan for the correction of anaemia should be sought to improve patient safety and outcome.

Electrical storm refers to a state of cardiac electrical instability characterized by multiple episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) within a relatively short period of time and is associated with increased mortality and morbidity. The management of electrical storm involves a variety of strategies, including sedation, anti-arrhythmic and electrolyte replacement as well as revascularization and electrical ablation. However, the management strategy in patients with refractory storm is less clear and may require more invasive approaches. We present a case of severe ventricular tachycardia storm refractory to conservative management that was managed with a HeartMate II left ventricular assist device.
