How to stop bleeding
Adult weight per kilogram of about 80 ml of blood. Body weight is 60 kg, the body blood is about 4800 ml.. A large amount of bleeding, blood vessels within the circulation of blood, the body is in a state of ischemia and hypoxia condition if the bleeding is too much, there will be life-threatening, must be blood transfusion. If the amount of bleeding accounted for 15% to 25% of the whole body blood, there will be hemorrhagic shock and bleeding volume accounted for 25% to 40% of the whole body blood, it is more dangerous, to rapid blood transfusion. In addition to blood transfusion, the bleeding is also very important.
1 stop the bleeding point oppression hemostasis method with the fingers of the blood supply artery to stop bleeding. The compression point is called the stop point. The bleeding point should be closer to the heart than the wound. Specific hemostasis points are as follows:
(1) the thumb pressed in the scalp in front of the upper ear bones, usually can touch the arterial pulse.
1, the superficial temporal artery point to massage the ear in front of the root of the zygomatic arch.
2, massage the posterior auricular artery oppression point between ear and mastoid.
3, occipital artery point to the mastoid pressure inside the root.
(2) the face of the thumb press Chin (Chin) in the middle of the lower margin of the L in front of the chewing muscles, normal people can touch the pulse of the artery.
(3) neck thumb flexion in the posterior cervical, the other 4 finger in the back of the neck, to force the direction of thumb of oppression.
(4) in the chest and under the armpit: the thumb is placed on the top of the clavicle, forced to press.
(5) of the wrist: the 4 fingers on the inside of the arm, and the brachial artery in the depression of the muscle.
(6) hand: thumb pressing on the inside of the wrist, the direction of the head of the bone force. Finger bleeding, available acupressure hemostasis.
(7) of the lower extremity: the heel of your hand pressed in the thigh roots bulky muscles Sag (the midpoint of the groin slightly below), to the head direction force oppression, or with both hands finger.
(8) foot: the anterior and posterior tibial artery of the anterior tibial artery.
Anterior tibial artery point for fibular head medial 2,5 cm to internal and external ankle front line midpoint of posterior tibial artery pressure point is between the calcaneal tuberosity and the medial malleolus.
2 direct compression hemostasis method (bleeding site of oppression)
(1) the use of sterile gauze or clean fabric, paper, etc., and then press.
(2) the injured arm or the lower limb is higher than the heart.
(3) with a bandage tightly wound, but not too tight, to prevent tissue necrosis.
The 3 packing method is suitable for the large and deep wounds of the neck and arms.
(1) first, the use of the tool will be sterile gauze in the wound, to stop the bleeding can be more than a piece of gauze.
(2) press the gauze.
(3) with a bandage or a triangle, the neck is wrapped around the upper arm.
4, tourniquet applies only to extremity arterial hemorrhage, generally used in compression bandage is invalid. If no special tourniquet, triangular scarf, scarf, tie, towel can also throw a generation.
(1), a strip of 5 centimeters wide (too narrow, too narrow, of the injured nerve and artery) is folded into a long strip of the wound.
(2) folded into small pieces and placed in the compression of the arterial blood vessels of a handkerchief.
(3) a tourniquet cannot be embedded in the joints, can be tied at the top of the. If applying a tourniquet is not too thick, underwear parts of the belt can be tied in the underwear outside.
(4) tourniquet wound in the arm or on the old, tight around 2 weeks, half a knot.
(5) put a strong stick in the 20-30 cm long knot. Lay a solid knot in the bar.
(6) twist stick tightening tourniquet, until the bleeding so far.
(7) if the bleeding has stopped, the excess available tourniquet or other items to stick strip fixed in place.
Standard pressure tourniquet upper limb 33.3 ~ 40000 kPa, lower 53.3 ~ 66700 PA.
1 small and narrow rope, with a band can destroy the subcutaneous tissue and nerve, prohibit the use of!
2 pen will do mark on the patient’s forehead at the tourniquet or write with tourniquet time, rushed to the hospital. Principle of dagger should be as short as possible to tie tight tourniquet time, the length of not more than three hours, if more than 1 hour should be relaxed 1 ~ 2 minutes, to prevent the necrosis of the distal limb ischemia.
