Heat heat affects dialysis patients

A new study from a researcher in the University of Wisconsin and the Faculty of Public Health has shown that the death of an adult, which has been undergoing renal dialysis, has jumped 15 to 20 % during extreme moist events. I did it. These events are defined as the heat index (measurement values ​​indicating how temperature and humidity feel) exceeds 105 degrees of Hana or more than 115 degrees a day. 。

“This is evidence that the warming planet is vulnerable, in this case, the risk of kidney dialysis people, which is likely to die in a very hot and humid climate.” UW School of Medicine and Public Health medicine and UW Health kidney scholars. “As a kidney specialist, we need to be particularly worried about dialysis patients and find a way to protect them from extreme weather.”

This study was published in American Journal of Kidney Diseases。

Dialysis patients often have other health conditions such as the handling of diabetes, heart and lung disease, liquid and electrolyte, all of which make it more difficult for people to endure extreme heat.

A healthy kidneys can help regulate body temperature and replace sweat loss by saving sodium and water. For those who have experienced renal failure, this ability is impaired or does not exist.

Blum and his colleagues analyzed the US renal data system records from 945,251 patients living in 245 urban areas, which began regular dialysis treatment between 1997 and 2016. The target of 498,049 patients was exposed to at least one of the 7,154 extreme thermal indices in 6 years. event. In the southern part, the maximum number of moist events occurred, 49.3 events in each urban area, followed by 29.9 events and 29.4 events. At the top of the midwest, including Wisconsin, there was a 3.1 thermal index event.

A total of 500,025 deaths occurred, 2.5 million ages follow -ups, and the risk of death of 18 % was 18 % higher. Researchers have adjusted data on variables such as age, gender, year of dialysis, and nearby poverty levels. The greatest relative risk of death is related to Alabama, Georgia, Florida, North Carolina, South Carolina, Virginia, and despite the same number of moist events, more than the southwest. It accounts for many deaths.

The most common cause of death among patients include cardiac -related cases such as myocardial infarction, cardiac arrest, arrhythmia, adaptive heart failure, and sepsis.
