What symptom is instant shock?

summary

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. Its main characteristics are: insufficient microcirculation perfusion in important organs, metabolic disorder and dysfunction of various systems of the whole body. In short, shock is the response of the body to the decrease of effective circulating blood volume, and is the pathological process of metabolism and cell damage caused by insufficient tissue perfusion. What symptom is instant shock? Let's talk about it

What symptom is instant shock?

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.

The patient is irritable, unconsciousness, shallow breathing, decreased temperature of limbs, low heart sound, weak pulse count, progressive decrease of blood pressure, which can be less than 50 mmHg or undetectable, pulse pressure less than 20 mmHg, wet and cold skin, little or no urine.

Acute heart failure is characterized by shortness of breath, cyanosis, rapid heart rate, low and blunt heart sound, galloping rhythm and arrhythmia. If the heart rhythm is slow, the face is gray, and the extremities are cold, it is also a sign of heart failure. The central venous pressure and the pulse pulmonary artery wedge pressure are increased. In severe cases, there may be pulmonary edema.

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.
