What reason is headache shock?
summary
Shock is a common phenomenon in life, mainly caused by insufficient blood supply. Here is a summary of the causes of shock, mainly in the following aspects. Shock can also be divided into different types according to its characteristics. What is the cause of headache shock? Let's talk about it
What reason is headache shock?
Cardiogenic shock in a narrow sense refers to the severe stage of pump failure in acute myocardial infarction (see acute myocardial infarction). In acute myocardial infarction, the symptoms of microcirculation failure of important organs, such as decreased blood pressure, insufficient skin perfusion, decreased renal blood flow and central nervous function, can be accompanied at the same time, and the hypotension caused by drugs (such as analgesics, vasodilators and diuretics), less food intake, loss of body fluid or insufficient rehydration can be excluded, The diagnosis of cardiogenic shock can be considered.
Hypovolemic shock hypovolemic shock is a kind of shock caused by massive blood loss (internal or external bleeding), water loss (such as vomiting, diarrhea, intestinal obstruction, gastrointestinal fistula, diabetic acidosis, etc.) and plasma loss (such as large area burn, peritonitis, trauma and inflammation) in vivo or in blood vessels. It is characterized by decreased venous pressure, increased peripheral vascular resistance and tachycardia. Hemorrhagic shock, traumatic shock and burn shock all belong to hypovolemic shock (see "upper gastrointestinal hemorrhage").
Anaphylactic shock is a rare type of shock. It is the anaphylactic reaction of human body to some biological products, drugs or animal and plant allergens. Allergens and antibodies act on sensitized cells, which release 5-hydroxytryptamine, histamine, bradykinin and other substances, causing peripheral vascular dilation, capillary bed enlargement, plasma exudation, and relative insufficiency of blood volume. In addition, there is often laryngeal edema and dyspnea caused by bronchospasm, which increases the pressure in the chest, thus reducing the amount of return blood and cardiac output (see "anaphylactic shock").
matters needing attention
In order to keep the respiratory tract unobstructed, nasal catheter is generally used for oxygen inhalation, with the flow rate of 4-6l / min. in case of severe hypoxia or cyanosis, it should be increased to 6-8l / min, or mask or positive pressure oxygen should be used according to the condition. Establish venous access as soon as possible
