"The weather is cold. I turn on two heaters and don't stop working for 24 hours. When I'm tired at home, I lie down on the sofa, watch TV when I wake up, drink some frozen carbonated drinks, strong tea and smoke." Grandpa Xu, 77, said that his comfortable old life had quietly changed half a month ago. Severe dehydration and excessive intake of sweets can cause blood sugar to burst, and the elderly are deeply trapped in diabetic hyperosmolar coma. During the Spring Festival, the family turned on two heaters to keep warm. Grandpa Xu was thirsty, so he drank frozen carbonated drinks to quench his thirst and reduce dryness. Then he fell in love with this taste. He had to eat frozen drinks for three meals a day and ate high sweet fruits such as grapes, watermelon and oranges until there were abnormalities such as nonsense, low spirits, sleepiness and blurred consciousness, which frightened his family and thought the old man had a stroke, Call 120 and send him to Changjiang Shipping general hospital Wuhan brain hospital for treatment. The hospital quickly opened the emergency green channel, stabilized the vital signs and improved the examination, so as to eliminate the risk of cerebrovascular accident in time. Subsequently, Gong Cheng, a doctor receiving department of endocrinology in Department of Endocrinology, found that Xu's blood sugar burst and blood pressure plummeted, and plasma osmotic pressure and electrolyte were all exceed the standard. Combined with the old people's daily life habits and illness, Gong Cheng said that patients had history of various underlying diseases such as diabetes and cerebral infarction. Although they regularly took medicine, they did not "control their mouths and legs" from their daily lives, but did not monitor blood sugar or seek medical treatment. Therefore, long-term blood glucose control was not good enough, and excessive heating could cause and aggravate infection and dehydration. In order to prevent the disease from worsening and endangering life, Guo Aili, director of the Department, immediately organized a medical team to carry out symptomatic treatment such as insulin hypoglycemic, massive rehydration and anti infection for Grandpa Xu. The next day, the old man's consciousness recovered, his mental state improved significantly, and his blood glucose and other indicators decreased significantly. Guo Aili said that when heating facilities are best used, it is best to avoid long time and close use. Pay attention to ventilation and water replenishment. Once there is dry mouth, drink, dry skin, collapse, blood pressure drop, mental disorder, and mental disturbance due to improper heating, it is better to go to the Department of endocrinology in regular hospitals in time to eliminate the acute complications of diabetes caused by abnormal blood sugar.
