How to deal with a bleeding forehead

If your forehead has been hit and is bleeding, you should not take it lightly. In this case, you need to go to the hospital for relevant examinations and treatment in time. This will be better for your body. Otherwise, internal bleeding may occur. This situation cannot be reflected through surface symptoms. You must go to the hospital for corresponding treatment in time to see improvement.

Internal bleeding

Internal bleeding is generally not easy to detect and may manifest itself through vomiting blood, bloody stools, etc. Once discovered, medical attention should be sought immediately.

External bleeding

There are three types of external bleeding.

Capillary bleeding

Capillary bleeding is red in color and drips from the wound. It can usually coagulate on its own or be covered with a Band-Aid.

Venous bleeding

Venous bleeding is dark red in color and blood gushes out of the wound. For small veins, you can apply a Band-Aid. For large veins, call 120 for help immediately, and at the same time press them with your hands or use bandages, tourniquets, etc. to stop the bleeding.

Arterial bleeding

Arterial bleeding is bright red in color, and blood spurts out of the wound in streams. The method of stopping bleeding is the same as that of large veins.

Notice

When using a tourniquet to stop bleeding, the time should be shortened and the tourniquet should be loosened every 20 to 30 minutes to allow a small amount of blood to flow through to prevent limb necrosis.

Abortion bleeding

The amount of bleeding after abortion is mainly related to the strength of the patient's uterine contraction, the coagulation function and the method of abortion chosen. The chosen abortion method causes less harm, and the patient's own quality is better. After the abortion, the uterus will have strong contractions and good coagulation function. There will be little or no bleeding. On the contrary, the amount of bleeding will be more. Generally speaking, the bleeding time is about 3-10 days, and the longest time will not exceed 15 days.

The human body has the function of stopping bleeding. Slow and small amounts of bleeding can usually stop on their own. This is mainly due to the reflex contraction of locally damaged blood vessels, or the aggregation of platelets at the damaged blood vessels to form blood clots through the coagulation process to prevent further bleeding. The blood in local tissues or body cavities can be eliminated through absorption or ossification. If a larger hematoma is not completely absorbed, it may be ossified or wrapped by fibers.

The effect of bleeding on the body depends on the amount of bleeding, the rate of bleeding, and the location of bleeding. The process of leaking bleeding is relatively slow, the amount of bleeding is small, and it will not cause serious consequences. However, if the exudative bleeding is extensive, such as extensive gastrointestinal mucosal exudative bleeding caused by portal hypertension in cirrhosis, hemorrhagic shock may occur due to temporary and excessive bleeding. The bleeding process of rupture hemorrhage is rapid. If 20% to 25% of the circulating blood volume is lost in a short period of time, hemorrhagic shock may occur.

Bleeding in important organs can be fatal even if the amount of bleeding is not large. For example, intrapericardial bleeding caused by heart rupture can lead to acute heart failure due to pericardial tamponade. Cerebral hemorrhage, especially brainstem hemorrhage, can cause death due to compression of important nerve centers. Local bleeding can lead to corresponding functional disorders, such as intracranial capsule hemorrhage causing contralateral limb hemiplegia, and retinal hemorrhage causing vision loss or blindness. Chronic bleeding can cause anemia.

Generally, the bleeding is slow and ruptured and can stop on its own. The mechanism is that the locally damaged arterioles spasm and thrombosis forms in the small veins, thus preventing further blood loss. Blood that flows into the body cavity or tissue can be absorbed, organized or encapsulated after a long time.
