Diagnostic criteria for neurogenic shock

The disease of neurological shock is relatively rare in our lives, but it can cause great harm to the patient's health. I hope you can avoid heatstroke in your life. For cases like neurological shock, if we want to detect it in life, we generally need to have a certain understanding of its diagnostic criteria, such as patients who frequently experience shock or patients with insufficient blood supply to the brain.

Neurogenic shock is caused by strong pain stimulation, medullary anesthesia or trauma, which can lead to insufficient cardiac output or insufficient blood return. Neurogenic shock refers to a hypotensive state caused by damage or action of the neural regulation that controls circulatory function due to primary or secondary causes. In obstetrics and gynecology, the most important cause of neurological shock is surgical anesthesia, especially high epidural anesthesia. When the sympathetic nerves are blocked, peripheral resistance decreases, blood fills below the block level, causing relative blood volume deficiency, reduced venous return, decreased cardiac filling and cardiac output, and hypotension.

Diagnosis

(1) A history of damage to the anesthesia or neuroregulatory organs, such as drug anesthesia, spinal anesthesia, epidural anesthesia, etc.; use of antihypertensive drugs for pregnancy-induced hypertension syndrome, etc.

(II) Clinical characteristics: The clinical manifestations of neurological shock have certain characteristics: ① The onset of shock is often extremely rapid and tends to be reversed quickly; ② Under normal circumstances, it is not accompanied by persistent and severe tissue perfusion insufficiency and microvascular damage; ③ The main clinical manifestations are insufficient blood supply to the brain and acute disturbance of consciousness.

After experiencing anxiety, palpitations, tremors, and pale complexion, the patient suddenly experiences a drop in blood pressure and syncope due to reflex vagus nerve excitement. During the examination, the heart rate was fast (slow during high spinal anesthesia), the blood pressure dropped to 9.3 kPa (70 mmHg), the total peripheral resistance and cardiac output decreased, and the venous pressure decreased or was normal (increased during high spinal anesthesia). There is no obvious microcirculation disorder, no exudation, normal urine volume, and normal circulating blood volume.

Based on the article's introduction to the treatment methods of neurological shock, I believe you all know that patients with neurological shock should take some corresponding measures in their lives. Try to avoid going out alone at noon, as this can easily lead to symptoms of shock. And if you want to go far away, it is best to have someone accompany you.
