Recently, the train crew of 120 Dongcheng emergency center received a patient with special epistaxis. The old woman was taking a bath when her left nostril suddenly bled and had not suffered trauma. The emergency doctor instructs the patient to tilt his head forward by telephone, be careful not to let the blood choke on the trachea, and immediately drive to the patient's home. After arriving at the scene, we found that the patient was an old man with hearing impairment. The large amount of blood on the ground and the left nostril, which was still bleeding, made the old man feel very flustered. The emergency doctor quickly instructed the family members to communicate with the patient in handwritten words, calmed the patient's mood, took the correct drainage posture, and filled and pressed to stop bleeding. The on-site nurse conducted relevant examinations for the patient and found that the patient's blood pressure was as high as 210 / 100mmhg. After further asking the family members about the medical history, it was learned that the elderly found hypertension during physical examination three years ago, but neither monitored blood pressure nor took drugs for control. After the doctor took intravenous medication on site to reduce blood pressure, the patient's nasal blood gradually stopped, and then sent to the nearest hospital for further treatment. Beijing Emergency Center reminds the public that high blood pressure will not only lead to epistaxis, but also lead to fundus hemorrhage and even intracerebral hemorrhage. Long term hypertension damages heart, brain, kidney and other organs. If the symptoms are serious, such as severe dizziness, headache, nausea, vomiting, blurred vision, chest pain, dyspnea, limb convulsions, or even unclear consciousness, call 120 in time for medical treatment. The temperature changes greatly after winter, which is a high incidence season of cardiovascular and cerebrovascular diseases. In addition to paying attention to cold prevention and warmth preservation, we also need to use drugs regularly and reasonably. Especially pay attention to the monitoring of basic diseases of the elderly, such as regular measurement of blood pressure and blood glucose. In case of abnormal blood pressure rise, do not panic. The emergency doctor suggests that you should calm down as much as possible at this time, sit still or lie still for about 1 hour, and then retest your blood pressure. If it is still high, you can appropriately increase antihypertensive drugs or go to a nearby hospital for treatment. (outlook new era)
