Survival after cadaveric lung transplantation (LTx) in respiratory failure recipients who were already dependent on ventilation support prior to transplantation is poor, with a relatively high rate of surgical mortality and morbidity. In this study, we sought to describe the short-term outcomes of bilateral sequential LTx (BSLTx) under extracorporeal membrane oxygenation (ECMO) support in a consecutive series of preoperative respiratory failure patients. ⋯ Although BSLTx in this critical population has varied surgical complications and prolonged length of postoperative ICU and hospital stays, all the patients observed in this study could tolerate the transplant procedures under VA ECMO support with promising pulmonary function and satisfactory short-term outcome.

The demographic shift in the age of most industrialized countries' populations is profoundly impacting all areas of healthcare, perhaps nowhere more so than critical care. As the proportion of elderly patients increases, so to will our consideration for admission of elderly patients to the intensive care unit (ICU). Whether explicitly acknowledged or not, intensivists routinely debate (both inwardly and outwardly) the benefit, utility, and patient-focused dignity of admitting very elderly patients to the ICU. Despite the apparent increase in demand for, and provision of critical care services to, the elderly, there are few data on the outcomes from these admissions, and how one might predict which elderly patients are most likely to derive benefit from the invasive and resource-intensive services provided in modern ICUs.

Extracorporeal membrane oxygenation is a supportive cardiopulmonary bypass technique for patients with acute reversible cardiovascular or respiratory failure. Favourable effects of haemofiltration during cardiopulmonary bypass instigated the use of this technique in infants on extracorporeal membrane oxygenation. The current study aimed at comparing clinical outcomes of newborns on extracorporeal membrane oxygenation with and without continuous haemofiltration. ⋯ Adding continuous haemofiltration to the extracorporeal membrane oxygenation circuit in newborns improves outcome by significantly reducing time on extracorporeal membrane oxygenation and on mechanical ventilation, because of better fluid management and a possible reduction of capillary leakage syndrome. Fewer blood transfusions are needed. All in all, overall costs per extracorporeal membrane oxygenation run will be lower.

As patients after cardiac arrest suffer from the consequences of global ischemia reperfusion, we aimed to establish the incidence of acute kidney injury (AKI) in these patients, and to investigate its possible association to severe hypoxic brain damage. ⋯ In this large cohort of patient after cardiac arrest, we found that AKI occurs in nearly 50% of patients when the new criteria are applied. Patients with unfavourable neurological outcome are affected more frequently. A significant association between the development of AKI and NSE levels indicating hypoxic brain damage was observed. Our data show that changes in serum creatinine may contribute to the prediction of outcome in patients with cardiac arrest. Whereas a decline in serum creatinine (> 0.2 mg/dL) in the first 24 hours after cardiac arrest indicates good prognosis, the risk of unfavourable outcome is markedly elevated in patients with constant or increasing serum creatinine.

Policies of fluid administration/restriction in critically ill patients have evolved over recent years. Abundant fluid resuscitation is encouraged during the early stage of severe sepsis. ⋯ Tests detecting volume unresponsiveness at any moment of fluid resuscitation or detecting volume unresponsiveness at any moment of fluid restriction would help to better assess the benefit/risk ratio of continuing such strategies. Measuring the short-term hemodynamic changes during passive leg raising can be reliably used for that purpose in both situations, even when patients are breathing spontaneously.
