Since the early days of lung transplantation the demand for donor organs has outstripped donor organ availability. Consequently waiting times continue to increase with patients of highest priority often waiting several weeks or even months until a suitable donor organ becomes available resulting in considerable mortality on the waiting list. These issues have led to renewed interest in bridging strategies for patients with end-stage lung disease. ⋯ New bridging strategies with awake extracorporeal membrane oxygenation (ECMO) seem to be hopeful alternatives in some patients. In the early intensive care unit (ICU) phase primary graft dysfunction, acute rejection, infections and surgical complications are common problems. Later, rejection, infection and sepsis, special airway complications and pulmonary bleeding may be reasons for ICU treatment.

β-blockers clearly prolong life in patients with heart failure and after myocardial infarction in all controlled prospective trials. Nevertheless, many colleagues and even more patients fear unwanted effects like low blood pressure, bradycardia, increased bronchial resistance, or erectile dysfunction. ⋯ In spite of these, we should encourage our patients, who profit from the beneficial actions of β-blockers, to take them regularly. Some controversial aspects of β-blocker therapy are discussed in the light of newer studies.

This report is about a married couple who were admitted to hospital suffering from gastrointestinal complaints after eating mushrooms. With the suspicion of poisoning with Amanita phalloides treatment started with elimination of the toxins, symptomatic therapy and specific therapy with silibinin. ⋯ Clinical symptoms follow a three-phase course with gastrointestinal complaints, an asymptomatic interval and finally the hepatorenal phase. Even in suspected cases of intoxication, treatment should be started by antidote therapy with silibinin.

The total anatomical and functional apparatus which allows normal ventilation of the lungs is known as the respiratory pump. An insufficiency of this system, which can be caused by a multitude of reasons, primarily affects the inspiratory musculature and especially the diaphragm. One of the essential clinical characteristics is rapid shallow breathing. ⋯ This is initially a non-invasive procedure but if unsuccessful intubation and invasive ventilation are indicated. The technical developments in the field of extracorporeal gas exchange systems are very promising. However, in view of the insufficient data, ventilation procedures using masks and tubes still remain the first choice methods.

Right-sided heart failure is a severe and often life-threatening complication of chronic pulmonary hypertension. The detection of trigger factors that induce right heart failure in previously stable patients is important to initiate a causal therapeutic strategy. Pulmonary embolism (PE) is a frequent cause of acute right heart failure and therapeutic strategies for PE are well documented in the current guidelines. ⋯ Intensive care management for overt right heart failure is complex and includes the use of pulmonary vasodilators, individual adjustment of diuretic or volume therapy, augmentation of myocardial contractility and left ventricular afterload. Therapeutic regimens aim at optimized filling of the right ventricle, improvement of myocardial perfusion by avoiding tachycardia, elevating systemic pressure and reducing right ventricular afterload. Early communication with a specialized center for pulmonary hypertension is recommended.
