Is shock a symptom?

summary

Shock. Shock itself is not a disease, it is just a symptom, or a combination of a series of symptoms. The cause of these symptoms is insufficient blood circulation in the body, and the body tries to compensate for this deficiency. Shock is a complex syndrome of systemic microcirculation dysfunction and serious disturbance of vital organs due to the sharp decrease of effective circulating blood volume, extensive, continuous and significant reduction of tissue blood perfusion after the invasion of strong pathogenic factors. At this time, the body function lost compensation, tissue ischemia and hypoxia, neurohumoral factor imbalance. Is shock a symptom? Let's talk about it

Is shock a symptom?

In the case of primary symptoms and signs, mild signs of excitement appear. Ruyi is still clear, but he is irritable and anxious, nervous, pale complexion and skin, mild cyanosis of lip nail bed, accelerated heart rate, increased respiratory rate, cold sweat, fine pulse, sudden or slight drop of blood pressure, even normal or slightly high, reduction of pulse pressure, and reduction of urine volume.

In the middle stage of shock, the patients were irritable, unconsciousness, shallow breathing, decreased temperature of limbs, low heart sound, weak pulse count, progressive decrease of blood pressure, which could be less than 50 mmHg or undetectable, pulse pressure less than 20 mmHg, cold and wet skin, and little or no urine.

The late stage of shock was DIC and multiple organ failure. DIC showed intractable hypotension, skin cyanosis or extensive bleeding, nail bed microcirculation congestion, poor efficacy of vasoactive drugs, and often coexisted with organ failure. Acute respiratory failure is characterized by progressive dyspnea, progressive hypoxemia, shortness of breath, cyanosis, pulmonary edema and decreased pulmonary compliance.

matters needing attention

Usually take the supine position, if necessary take the head and trunk to raise 20 °～ thirty °、 Lower limb elevation 15 °～ twenty °， In order to facilitate breathing and venous return of lower limbs, and ensure cerebral perfusion pressure at the same time; Keep the respiratory tract unobstructed, and use nasal catheter or mask method for oxygen inhalation. If necessary, establish artificial airway and ventilator for auxiliary ventilation; Maintain a normal temperature, keep warm when hypothermia, and try to cool when high temperature; Venous access should be established as soon as possible, and drugs should be used to maintain blood pressure. Try to keep the patient quiet, avoid moving, use small doses of analgesic, sedative, but to prevent respiratory and circulatory inhibition.
