What are the three types of bleeding? There are three types of external bleeding

Blood flows through a network of blood vessels throughout the body. Blood vessels can be divided into arteries, veins, and capillaries.

There are 3 types of bleeding when blood vessels are damaged and ruptured. Therefore, it is helpful to distinguish the type of bleeding in time when bleeding, which is very helpful in judging the severity of the disease. Bleeding is a common phenomenon in trauma, and excessive bleeding can cause shock and life-threatening Depending on the bleeding site, it can be divided into external bleeding, internal bleeding, and subcutaneous bleeding.

There are three types: (1) external bleeding, which can be seen to flow out of the wound Generally, the bleeding caused by trauma belongs to external bleeding When we rescue trauma patients, most of the bleeding that needs to be stopped in time is external bleeding (2) Internal bleeding, the bleeding blood is stored in the abdominal cavity or tissue, and generally cannot be directly observed Through the clinical manifestations of the patient and various examination methods, the bleeding site can be determined Some trauma patients have hemorrhagic shock, and should be highly vigilant for internal bleeding (3) Subcutaneous hemorrhage, subcutaneous tissue.

Bleeding within Bleeding is characterized by bruising, swelling of local tissues, and local tension blisters **Surface intact and undamaged Trauma patients have tissue contusions during the injury process.

It can cause subcutaneous hemorrhage, and generally does not require special treatment Therefore, the statement that hemorrhage is external hemorrhage is incorrect According to the different damaged blood vessels, it can be divided into three types: arterial hemorrhage, venous hemorrhage, and capillary hemorrhage: (1) Arterial hemorrhage, caused by arterial vascular injury The bleeding is in the form of a squirt, the blood is bright red, the amount of bleeding is large, and the bleeding point can often be found.

2) Venous hemorrhage, caused by venous vascular injury, manifested as slow blood outflow, dark red blood, relatively small amount of bleeding, bleeding site can be found (3) Capillary hemorrhage, caused by small vascular injury, manifested as blood oozing from the wound (or wound), bright red blood, often no bleeding point bleeding can often coagulate into a blood crust <>

Arterial hemorrhage: Arterial blood is bright red in color and high in oxygen. Because arterial blood is blood that has just come out of the heart, the blood pressure in arterial blood is very high.

Due to the beating of the heart, the cut aortic blood vessels instantly spurt blood several feet high. Venous bleeding: venous blood is dark red in color and low in oxygen.

Because venous blood is not blood that is exported directly from the heart, but from capillaries in the body's tissues, venous blood has lower blood pressure than arterial blood. Still, blood gushes out of the cut vein. Capillary hemorrhage:

This bleeding is usually caused by abrasions. However, when the capillaries under the skin break down and blood flows into the tissues, the bruising of the wound appears. This bleeding does not cause significant blood loss.

External hemorrhage is classified as arterial hemorrhage, venous hemorrhage, and capillary hemorrhage. Arterial hemorrhage is characterized by bright red color, rapid blood flow, and often in the form of a squirt; Venous bleeding is characterized by dark red venous blood and slow blood flow; Capillary hemorrhage, blood slowly leaking out of the arteries is to send blood from the heart to all parts of the body, and the direction of blood flow is the heart arteries; Veins are blood vessels that send blood from all parts of the body back to the heart, and the direction of blood flow in the veins is the heart veins Therefore, when a large vein is injured and bleeding, the correct first aid method is to use acupressure (or tourniquet) to stop bleeding at the distal end, which can be bandaged with gauze bandage or acupressure to stop bleeding; Arterial hemorrhage stops proximal and can be compressed with a tourniquet or bandage; Capillary bleeding can stop bleeding naturally. <>

External bleeding is a phenomenon of bleeding caused by a rupture or trauma to a blood vessel in one part of the body. According to different ** and the different slag at the bleeding site, external bleeding can be divided into three types.

The first is extra-arterial hemorrhage, which is usually caused by a ruptured arterial blood vessel or trauma. Arterial hemorrhage is characterized by bright red blood, rapid blood flow, and a pulse rate proportional to the amount of bleeding, which can be life-threatening if not timely**.

The second type is external venous bleeding, which is usually caused by rupture or trauma in the veins. Venous bleeding is characterized by dark red blood, slower blood flow, and less blood volume, but if the bleeding site is deep, a large amount of blood may form, leading to complications such as infection.

The third type is capillary external bleeding, which is usually caused by damage to the capillaries. Capillary hemorrhage is characterized by a reddish appearance of blood, slow blood flow, and a small amount of bleeding, but if the bleeding site is deep, a large amount of blood may also form and need to be treated promptly.

External bleeding can be divided into three types, namely pre-arterial recurrent bleeding, venous bleeding, and capillary bleeding.

Arterial hemorrhage refers to the bleeding from the bleeding opening of the artery, the blood volume is large, the color is bright red, the pulse beats and the phenomenon of Sun staring spray is more obvious.

Venous bleeding is when bleeding comes from a vein, the blood flow is slow, dark red in color, and serpentine, and the blood flow decreases or stops when the blood vessel is compressed.

Capillary hemorrhage is minimal and often does not require emergency treatment. Blood can leak from the capillaries into the surrounding tissues, forming congestion.

1.Extra-arterial hemorrhage: refers to bleeding caused by the rupture of an artery in a blood vessel, which is characterized by bright red color, strong ejection and short duration, and can be life-threatening once the bleeding is large.

The most common cause of extra-arterial hemorrhage is trauma, surgical injury, etc.

2.External venous hemorrhage: refers to bleeding caused by the rupture of a vein in a blood vessel, which is characterized by a dark red color, slow flow, long duration, and is generally not life-threatening. The most common causes of extravenous bleeding are varicose veins, deep vein blind thrombosis, etc.

3.Capillary external hemorrhage: refers to the slow bleeding caused by capillary rupture, which is characterized by bright red color and strong exudation, but the amount of bleeding is generally small and not life-threatening. The more common causes of capillary external bleeding are inflammation, excessive exercise, etc.

Internal bleeding is directly sent to the hospital or dialed 120 External bleeding is divided into arterial bleeding, venous bleeding and capillary bleeding Arterial bleeding is characterized by bright red color, rapid blood flow, and often in the form of a jet; Venous bleeding is characterized by dark red venous blood and slow blood flow; Capillary hemorrhage, blood slowly leaking out of the arteries is to send blood from the heart to all parts of the body, and the direction of blood flow is the heart arteries; Veins are blood vessels that send blood from all parts of the body back to the heart, and the direction of blood flow in the veins is the heart veins Therefore, when a large vein is injured and bleeding, the correct first aid method is to use acupressure (or tourniquet) to stop bleeding at the distal end, which can be bandaged with gauze bandage or acupressure to stop bleeding; Arterial hemorrhage stops proximal and can be compressed with a tourniquet or bandage; Capillary bleeding can stop bleeding naturally, and the wound can also be band-aided Therefore, when the capillary ruptures and bleeds, the wound is smaller and the bleeding is not much, so use a band-aid to stop the bleeding, and there is no need to call the emergency ** "120".

So the answer is: internal and external bleeding (arterial, venous, and capillary bleeding); Arterial bleeding should be stopped at the proximal end, venous bleeding should be stopped at the distal end, and capillary bleeding can be stopped naturally, or the wound can be banded with a band-aid

According to the different mechanisms that cause bleeding, bleeding disorders can be divided into three categories:

Coagulation process. 1) Abnormal vascular factors: including abnormal blood vessels and abnormal extravascular factors cause bleeding diseases. Henoch-Schonlein purpura, vitamin C deficiency, hereditary telangiectasia, etc., are caused by abnormalities in the blood vessels themselves.

Senile purpura, homocystinuria, etc. are caused by extravascular abnormalities.

2) Platelet abnormalities: changes in the number of platelets and dysfunctions such as adhesion, aggregation, and release reactions can cause bleeding. Idiopathic thrombocytopenic purpura, drug-induced thrombocytopenia, and thrombocythemia are all bleeding disorders caused by abnormal platelet counts.

Platelet weakness and giant thrombocytosis are bleeding disorders caused by platelet dysfunction.

3) Coagulation factor abnormalities: including congenital coagulation factors and acquired coagulation factor abnormalities. For example, hemophilia A (lack factor) and hemophilia B (lack factor) are both chromosomal recessive hereditary bleeding disorders.

Most bleeding caused by vitamin K deficiency and liver disease is caused by abnormal acquired coagulation factors.

It is characterized by spontaneous bleeding or bleeding that does not stop after a minor injury.

The clinical manifestations of bleeding disorders caused by different ** are different, which can be manifested as epistaxis, gingival bleeding, **purpura, gastrointestinal bleeding, severe bleeding after tooth extraction or surgery, heavy menstrual bleeding in women, and heavy bleeding after childbirth.

Abnormal presentation in this segment.

Platelet abnormalities.

1) Thrombocytopenia Decreased platelet production: aplastic anemia, leukemia, infection, drug suppression, etc.; Platelet destruction.

platelets; Idiopathic thrombocytopenic purpura, drug-immune thrombocytopenic purpura; Excessive platelet depletion: thrombotic thrombocytopenic purpura, disseminated intravascular coagulation.

2) Thrombocytosis Methoda: essential thrombocythemia; Secondary: secondary to chronic myeloid leukemia, postsplenectomy, infection, trauma, etc.

3) Platelet dysfunction hereditary: platelet weakness, macroplatelet disease, primary thrombocytopathy; Secondary: Secondary: secondary to drugs, uremia, liver disease, dysglobulinemia, etc.

Coagulation abnormalities. 1) Hereditary hemophilia A, hemophilia B, factor deficiency, prothrombin deficiency, hypo(no) fibrinogenemia, von Willebrand disease and congenital factors, deficiency, abnormal fibrinogenemia, etc.

2) Consumption of coagulation factors caused by acquired severe liver disease, uremia, vitamin K deficiency and disseminated intravascular coagulation.

iii) Circulating anticoagulant substances increased or hyperfibrinolytic factor antibodies, factor antibodies, heparin-like anticoagulant anticoagulants**, primary fibrinolysis and secondary fibrinolysis caused by disseminated intravascular coagulation.

Arterial venous capillaries.

Analysis: This question examines the type of bleeding, first of all, to determine what kind of blood vessel is broken

Answer: Bleeding is a common phenomenon in trauma, excessive bleeding can cause shock and life-threatening According to the different bleeding sites, it can be divided into three types: outgoing hemorrhage, internal bleeding, and subcutaneous hemorrhage

1) External bleeding.

It can be seen that blood flows out of the wound Generally, the bleeding caused by trauma is external hemorrhage When we rescue trauma patients, most of the bleeding that needs to be stopped in time is external hemorrhage

2) Internal bleeding.

The bleeding blood is stored in the abdominal cavity or tissues, and generally cannot be directly observed The bleeding site can be determined through the patient's clinical manifestations and various examination methods Some trauma patients have signs of hemorrhagic shock, and should be highly vigilant for the presence of internal bleeding

3) Subcutaneous bleeding.

Bleeding in subcutaneous tissues Bleeding is characterized by bruising, swelling of local tissues, and local tension blisters **Surface intact and no damage In trauma patients, during the injury process, the tissue is contusion, which can cause subcutaneous bleeding, and generally does not require special treatment Therefore, it is incorrect to say that bleeding is external bleeding

According to the different damaged blood vessels, it can be divided into three types: arterial hemorrhage, venous hemorrhage, and capillary hemorrhage

1) Arterial hemorrhage.

Caused by arterial vascular injury, bleeding is in the form of a squirt, the blood is bright red, the amount of bleeding is large, and bleeding points can often be found

2) Venous bleeding.

Caused by venous vascular injury, it is characterized by slow blood outflow, dark red blood, relatively small bleeding, and bleeding sites can be found

3) Capillary hemorrhage.

Caused by minor vascular damage Blood oozing from the wound (or wound), blood is bright red, and bleeding points are often not found, and bleeding often coagulates spontaneously into a blood crust

Therefore, external bleeding can be divided into three types: arterial bleeding, venous bleeding, and capillary bleeding

So the answer is: arteries; Vein; Capillaries

Comment: The key to answering such questions is to know the type of bleeding

Any part of the heart's vascular system that drains all blood components or red blood cells is called hemorrhage. When blood flows out of the body, it is called external hemorrhage; Bleeding into the body cavity or tissue is called internal bleeding. The basic cause of bleeding is the destruction of the integrity of the blood vessel wall, which can be divided into rupture bleeding and exudative bleeding depending on the cause of bleeding.

1) Rupture hemorrhage: Mechanical damage, inflammation, and ulceration of the blood vessel wall.

and erosion of tumors, as well as pathological changes in the walls of blood vessels themselves (arteriosclerosis.

aneurysms), which can cause blood vessels to rupture and cause bleeding. If the outflow of blood accumulates in the interstitial space of the tissue or under the capsule of the organ, and compresses the surrounding tissue, it is called a hematoma; If blood flows into a body cavity, it is called luminal hemorrhage or hybrium. At the same time, according to the different types of ruptured blood vessels, they are divided into arterial hemorrhage, venous hemorrhage and capillary hemorrhage.

2) Exudative hemorrhage occurs in small blood vessels and capillaries, and there is a rupture of blood vessels that is invisible to the naked eye, but red blood cells can leak out of the blood vessels. This is because the blood vessel wall is dystrophied, which increases the permeability of the blood vessel wall, and red blood cells can leak out of the blood vessel. In swine fever.

Anthrax and other infectious diseases.

This bleeding can be seen in diseases such as hemosporidiosis and poisoning. The main manifestations are punctate, plaque, strip and diffuse.
