[Coronavirus disease 2019 (COVID-19): update for anesthesiologists and intensivists March 2020].
The current outbreak of coronavirus disease (COVID-19) has reached Germany. The majority of people infected present with mild disease, but there are severe cases that need intensive care. Unlike other acute infectious diseases progressing to sepsis, the severe courses of COVID19 seemingly show prolonged progression from onset of first symptoms to life-threatening deterioration of (primarily) lung function. ⋯ Severe ARDS reflects the hallmark of a critical course of the disease. Preventing nosocomial infections (primarily by correct use of personal protective equipment) and maintenance of hospitals' operational capability are of utmost importance. Departments of Anaesthesia, Intensive Care and emergency medicine will envisage major challenges.

[Foundations of Volumetric capnography : Principles of monitoring of metabolism and hemodynamics].
Capnography is the graphical representation of the carbon dioxide (CO2) concentration in expired air. Using this monitoring procedure, the kinetics of CO2 of mechanically ventilated patients can be assessed in a noninvasive way and in real time. This article highlights the importance, particularly of volumetric capnography (VCap), for clinical monitoring of mechanically ventilated patients. The procedure provides important information on the breathing, ventilation, metabolism and hemodynamics of patients.

The Canadian Critical Care Society performed a meta- analysis to assess the benefits and risks of the application of vasopressin and vasopressin- analogues in distributive shock. Their results were formulated as a Guideline in 2019. ⋯ Also the Canadian guideline now, implicating recently published studies, argues for the use of vasopressin or vasopressin- analogues in addition to an existing norepinephrine therapy, even though the level of evidence remains still low and there's no simple therapeutic algorithm formulated. This is based on a lowered incidence of newly- diagnosed atrial fibrillation and decreased mortality rate while administration remains safe.

Physical, cognitive and social frailty is increasingly being recognized as a prognostic factor in the perioperative treatment of older patients; however, the concept of frailty has not been introduced into clinical routine in anesthesia. ⋯ In contrast to commonly used perioperative risk classifications, frailty is a sensitive marker for the patient's biological age. Therefore, it appears more suitable for estimating the perioperative risk than chronological age or other conventional tools, such as the ASA classification and is therefore a prerequisite for patient centered treatment pathways.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are therapeutic options for the treatment of intra-abdominal neoplasms. Following the resection of all visible tumor areas by CRS, microscopic tumor areas are treated with HIPEC. This procedure increases the quality of life and survival. ⋯ The main concern of the anesthesiologist is the massive volume loss, volume shift and metabolic alterations. Patients with a high comorbidity should undergo preoperative optimization to reduce the perioperative morbidity and mortality especially by protracted interventions.
