[New challenges for intensive care medicine due to climate change and global warming].

backgroundIn the last five decades a continuous increase in the average global temperature has been recorded. Furthermore, natural disasters (e.g. heat waves, severe storms, floods and large forest fires) are becoming more frequent. The impact of global warming and climate change on health involves an increase in respiratory, cardiovascular, renal and cognitive mental diseases. Furthermore, a change in the frequency and patterns of infectious diseases can also be observed in Europe. MATERIAL AND

methodsThis article presents the most important studies that investigated diseases associated with the climate change, with special reference to those that represent a challenge for intensive care medicine.

resultsCurrently available epidemiological data and statistical extrapolations indicate that diseases resulting from the climate change (acute infection-related respiratory and intestinal diseases, exacerbation of pre-existing pulmonary lesions, heat-related dehydration, cerebral insults and myocardial infarction) are relevant for intensive care medicine. Particular emphasis is placed on a significant increase in acute kidney damage during heat waves. A previously unknown pattern of infectious diseases necessitates new knowledge and targeted management. In some studies, persisting mental impairments were registered during heat waves and natural disasters, e.g. posttraumatic stress disorder.

conclusionIntensive care medicine must be prepared for the challenges due to global warming and climate change. Slow but continuous changes (e.g. rise in temperature) as well as acute changes (e.g. heat waves and natural disasters) will induce an increased need for intensive medical care services (e.g. an increase in the need for renal replacement procedures). Intensive care physicians will need to be familiar with the diagnostics and management of diseases associated with the climate change. An initiative of the specialist societies involved would be welcomed.
