Cannabinoid hyperemesis syndrome (CHS) is caused by regular cannabis consumption and marked by cyclic episodes of severe emesis, often years after the beginning of cannabis consumption. Classical antiemetic treatment often shows no effect and fatal outcomes have sometimes also been reported. ⋯ At this point in time he had already undergone an abdominal computed tomography (CT) and gastroscopy, both with no pathological findings. The symptoms completely receded 6 months after presentation by maintaining cannabis abstinence.

Intravascular fluid administration belongs to the cornerstones of perioperative treatment with a substantial impact on surgical outcome especially with respect to major abdominal surgery. By avoidance of hypovolemia and hypervolemia, adequate perioperative fluid management significantly contributes to the reduction of insufficient tissue perfusion as a determinant of postoperative morbidity and mortality. ⋯ Fluid management already starts preoperatively and should be continued in the postoperative setting (recovery room, peripheral ward) considering a patient-adjusted and surgery-adjusted hemodynamic monitoring. Communication between all team members participating in perioperative care is essential to optimize fluid management.

Catheter-guided interventional implantation of cardiac valves is one of the main developments in cardiology over the past 15 years. It is characterized by a close interdisciplinary cooperation in the heart team (H-team), which consists of cardiac anesthesiologists, cardiologists and heart surgeons. This co-responsibility for anesthesia, which is demanded by the legislator (Federal Joint Committee, G‑BA, July 2015), includes not only qualified training for the cardiac anesthesiologist, including transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) but also several years of experience in cardiac anesthesia and correlates with the recommendations of the German Society for Anaesthesiology and Intensive Care Medicine. ⋯ This article discusses the interventional procedures of heart valvular diseases as well as the hemodynamic changes associated with the procedures from the anesthesiologist's point of view. To present examples, we have selected transcatheter aortic valve replacement (TAVR) and the interventional procedure of mitral and tricuspid valve insufficiency called MitraClip and TricaClip. A thorough examination of the procedural risk rate shows that despite minimizing the surgical intervention by miniaturizing the devices, the presence of an experienced cardiac anesthesiologist is obligatory.
