Emergency Vascular Wound
Vascular wounds are often caused by traffic accidents or daily life: fractures poking blood vessels, traumatic injuries; by being hit like: guillotine knife, pear or sword stab, bombs, mines, lethal bullets ...
Signs of detection
Large blood vessel wounds often cause acute anemia. Due to rapid and extensive blood loss, it is likely to lead to shock due to blood loss
With open wounds that bleed out, blood that could burst into rays or ooze could easily be identified. If the wound has been tourniquet or bandage, it is easy to diagnose when bleeding, it is easy to diagnose, if not bleeding, be alert, check the pulse to determine whether or not blood vessels are damaged
Wound that does not bleed out can be met in two cases: one is a vascular injury that has stopped bleeding; second is subcutaneous hematoma.

Blood vessel wounds after first aid has stopped the bleeding: it looks like a software wound, very easy to be missed. Therefore, you need to look for signs of peripheral anemia such as: cold, cold injured limb, no pulse or pulse weaker than the healthy side, decreased movement or loss.
Vascular wounds can cause acute anemia if not handled promptly
Sometimes blood vessel wounds can be self-sustained: the rupture of the blood vessel shrinks into the soft tissue, the endothelium flips into the lumen, facilitating the formation of a clot that blocks the end of the blood vessel.
Sometimes, due to excessive bleeding, the blood pressure will drop, causing the blood to stop, but if the bleeding does not stop immediately after resuscitation, the blood pressure continues to bleed. In some cases, a hematoma compresses blood vessels, causing the blood to stop flowing.
Hematoma under the skin has two forms: hematoma spread, beat heart rate, so long patients show signs of anemia. Localized hematoma: a typical case if the leg is injured in the calf, because the hematoma is restricted by the limbs, so it cannot grow but is very tight, preventing artery blood from coming and static blood The veins should be warm, purple, without veins, very painful
This case if not handled promptly will cause gangrene.
Hematomas often have complications: infection, pyoderma cause swelling, heat, redness, pain very easily confused with a hot abscess; hematoma is broken out causing intense bleeding, life-threatening victims.
Vascular wounds can cause dangerous complications such as death due to acute anemia, poisoning, gangrene, muscle spasms, sequelae of aneurysm and circulatory - veins.
First aid like?
When you encounter a victim with a vascular injury, you need to give first aid to save the victim's life by: placing a tourniquet, a bandage, pressing a blood vessel. The procedure is as follows: Placing a tourniquet is a good method of hemostasis, but requires the following rules to be followed: Make the reservation most visible, closest to the wound, prioritize transporting the victim to the hospital first According to the timetable
After the first aid, patients should be taken to the hospital for the best treatment
During the placement of the tourniquet, relax the tourniquet for an hour for a few minutes to allow the blood to flow down to nourish the lower part of the wound, then continue to tighten the tourniquet as the blood begins to flow again.
When disassembling the tourniquet for actual treatment, means must be provided to stop the bleeding and recover. Placing a tourniquet only in the following cases: a crushed limb no longer capable of conservation; place a tourniquet at the place of the accident, but near a hospital, the time to transport patients to the hospital is less than an hour; Place temporarily for a short time to prepare for surgery.
- Hemostatic bandage: Use a bandage or a small folded towel to form a lump on the wound and bandage up to stop bleeding, wrap the bandage tightly around the limb until no blood is absorbed. The best way to stop bleeding is to use an elastic bandage.
This simple method is easy to perform, has good hemostatic effect and does not cause bad consequences for the affected area.
- Press your finger against the blood vessel: Use your finger to press the path of the upper blood vessel (closer to the heart than the wound) into the bone base. The location is often used to press the vein: in the upper limb is after the collarbone, if the bleeding of the subclavian artery in the shoulder, arm At the incision of the artery, if there is bleeding of the axillary artery and arm artery, in the forearm area
At the edge of the dicey muscle, in the elbow fold, if there is bleeding of the artery and the artery, in the forearm. Lower extremities: mid-point ingestion, if bleeding of femoral artery due to wound under thigh. At the hollow, if bleeding of the artery in the lower leg ...
In addition, you can fold the elbow or knee maximum and press on the body to stop the bleeding, this measure applies when no pressure tape or place a tourniquet.
Use clamps to stop blood vessels. Preliminary anti-shock: by warming the victim, giving the patient heart medication, pain relief.
Treatment in the hospital includes: Positive resuscitation, cases of rapid blood loss and many just transfusion and surgery to stop bleeding. Antibiotics are used against infections and tetanus vaccination
In situ: widening the wound to find the tip of the blood vessel that is constricted, cutting out the splintered organization. . Dịch vụ: Thiết kế website, quảng cáo google, đăng ký website bộ công thương uy tín
