Syncope occurs from time to time in high temperature weather

Syncope occurs from time to time in hot and hot weather. What emergency measures should be taken in case of syncope? What kinds of syncope should be paid more attention to? Syncope in medicine refers to the brain does not have enough blood supply, resulting in a temporary loss of consciousness. It is characterized by rapid occurrence and rapid recovery. However, due to the uncertainty of the time and place of syncope and the acute onset, the potential risk should not be underestimated.

There are seven common causes of syncope

Vasovagal syncope: it refers to the stimulation of certain specific trigger factors, resulting in systemic vasodilation and bradycardia, resulting in blood pressure drop, cerebral ischemia leading to syncope. When the mood is under considerable pressure, extreme fatigue, panic, or in a crowded environment, it is easy to occur. In addition, it is related to some specific situations, such as urination, gastrointestinal tract stimulation, cough, and spraying Sneeze, etc.

Carotid sinus sensitivity: this type of syncope is often caused by the neck being squeezed and stimulated before the attack. It often occurs when the male shaves and shaves his beard, such as wearing hard collar, high collar and other band collar clothing, or the person who fastens the collar is also at this risk.

Postural hypotension: in the process of changing posture from lying, squatting, sitting to standing, the blood pressure cannot be adjusted and improved in time, which affects the blood supply of the brain.

Hypoglycemia: often occurs in office workers who don't eat breakfast, and patients with a history of hunger, diarrhea and diabetes.

Heatstroke: after long-term exposure to high heat and humidity, the thermoregulation center cannot transfer the excess heat from the body through sweating and skin heat dissipation, which will induce syncope.

Serious arrhythmia: for example, the heart rate is too fast or too slow, the rhythm is irregular, and some elderly people with cardiovascular diseases. This kind of syncope is usually dangerous. If it is serious, it may be life-threatening. It is the main cause of sudden death.

Brain diseases: the most common diseases are caused by hypertension and atherosclerosis, including syncope caused by brain-derived diseases such as transient ischemic attack, stroke and severe migraine.

In case of sudden syncope, what emergency treatment can we take before the arrival of 120 ambulance? First of all, it is necessary to observe whether the patient's breathing is stable and whether the airway is unobstructed. The neck can be padded up, and the mandible can be held up to make the head tilt back, and the patient's head should be tilted to one side at the same time. For patients with syncope and fall, it is necessary to check whether there is trauma, to take hemostasis measures for bleeding, and to monitor the pulse and blood pressure of patients. If syncope patients recover consciousness, it is not appropriate to stand up immediately, should be placed in situ rest and add appropriate water; for patients who lose consciousness for a long time, should be decisively sent to a doctor for treatment.
