Late one night recently, an emergency medical team from Changxindian Emergency Station of the Fengtai Branch of Beijing 120 received a dispatch concerning an adult man who had suddenly developed generalized convulsions and was in critical condition. Upon receiving the call, the team immediately set out with emergency equipment. While en route, Dr. Wang Peng promptly contacted the patient's family to obtain detailed information about his medical history and symptoms. He instructed the family on how to ensure the safety of the scene and prevent the patient from being injured by striking objects or falling from the bed during the convulsions, while also reassuring the family. Driver He Zhongping drove steadily and swiftly, helping the team gain valuable time for the rescue.

Upon arrival, the team quickly assessed the patient's condition. The patient was a 44-year-old man with a history of type 2 diabetes who had been using insulin for long-term blood glucose control. He had suddenly developed generalized convulsions during the night, accompanied by profuse cold sweating. Based on the patient's medical history and clinical presentation, Dr. Wang initially suspected a severe hypoglycemic emergency. Nurse Wang Yifan immediately performed a point-of-care blood glucose test, which showed a level of only 1.8 mmol/L, well below the clinical alert threshold of 3.9 mmol/L for patients with diabetes. The team immediately established intravenous access in accordance with emergency treatment protocols and administered concentrated intravenous glucose. Following treatment, the patient's consciousness gradually returned, and he was able to respond normally. A repeat blood glucose test showed that his level had risen to 6.3 mmol/L, with only mild weakness in his limbs. Once his vital signs had stabilized, the patient was safely transported to a nearby hospital for further evaluation.

Hypoglycemia is a common metabolic emergency, and its severity is directly related to how far and how long blood glucose levels fall. In the general population, blood glucose levels below 2.8 mmol/L, and in people with diabetes, levels below 3.9 mmol/L, may cause early symptoms such as weakness, profuse sweating, palpitations and trembling of the limbs. As hypoglycemia progresses, it may lead to altered perception and fluctuations in blood pressure. In severe cases, it can cause convulsions, impaired consciousness and even coma. Prolonged hypoglycemia lasting more than six hours may result in irreversible brain injury and, in extreme cases, can be life-threatening.

Beijing 120 Health Tip

Hypoglycemia should be managed according to the patient's level of consciousness and severity of symptoms. If the person is conscious and able to swallow safely, give a fast-acting source of sugar, such as candy or a sugary drink, immediately. If the patient has severe symptoms, including altered consciousness or loss of consciousness, do not give food or water by mouth, as this may cause choking or aspiration. Call 120 immediately for emergency assistance.
