The Red Cross reminds the general public that accidental injuries are always present. Only by mastering the knowledge and skills of first aid can your life and health be protected as much as possible. 2008 is the fourth World First Aid Day and 2005 is the first World First Aid Day.

It is inevitable to encounter unexpected injuries from family members or others in life. After encountering accidental injuries, when sending emergency help to professional rescue organizations, we should be prepared and actively respond.

With several common accidental injuries, the reporter visited several related professionals. Question 1: The most common accidental injuries in life should be identified as traffic accidents. When encountering traffic accidents, people are often at a loss. What should people who are not injured do at this time? A: After dialing 120 and 1 19, you can quickly check the injuries of the wounded. You can call loudly to check whether the wounded are awake to judge whether there is craniocerebral trauma.

Touch the carotid artery to check whether there is a heartbeat; Put your face close to the victim's nostril and feel if you are breathing. If the injured person has lost consciousness, heartbeat and breathing, cardiopulmonary resuscitation should be carried out immediately.

If the wounded are found to be bleeding heavily, stop bleeding and bandage immediately. If the injured person has a fracture, the fixation should be simplified.

Question 2: Last month, three workers died of hydrogen sulfide poisoning in our city. Because the workers did not take preventive measures, they were killed one after another, which aroused strong repercussions from all walks of life. So, how to prevent hydrogen sulfide poisoning? A: First of all, rescuers must wear oxygen masks and belts to ensure their own safety. Secondly, quickly move the poisoned person to fresh air, loosen the button and belt of the poisoned person, clean the mouth, keep the respiratory tract unblocked, and give artificial respiration if necessary.

Question 5: If the patient suddenly has a mouth-eye coma at home, what disease may it be? How should we treat it?

1. Shock 1. Definition and classification: it is a comprehensive disease caused by various reasons, which leads to insufficient blood perfusion, hypoxia of tissues and cells and damage of important organs.

The main manifestations are blood pressure drop, pale face, cold skin, weak pulse, oliguria, indifferent expression, slow response or abnormality. There are many reasons for shock, which can be generally divided into the following categories according to different causes: (1), traumatic shock: extensive and serious damage to tissues and organs caused by various serious injuries such as fracture, extensive burn, extrusion and war injury.

(2) Hypovolemic shock: due to massive blood loss such as ulcer bleeding, ectopic pregnancy rupture or massive loss of body fluids such as severe vomiting and diarrhea. , resulting in a sharp decrease in circulating blood volume. (3) Toxic shock caused by infection: The occurrence of this shock is mainly related to the toxic effect of bacteria. Common diseases include lobar pneumonia, toxic dysentery, fulminant epidemic cerebrospinal meningitis and postpartum infection.

(4) Cardiogenic shock: Due to the heart itself, the myocardial contractility is weakened and the cardiac output is sharply reduced, leading to shock, such as acute myocardial congestion, severe cardiomyopathy and severe heart failure. (5) Anaphylactic shock: allergic reaction caused by certain drugs such as penicillin and serum preparations such as tetanus antitoxin and diphtheria antitoxin.

2, the principle of rescue shock No matter what type of shock, its pathophysiological change is the reduction of effective circulating blood volume, so the blood volume should be supplemented as soon as possible to ensure blood perfusion of tissues and organs. (1). Increase the patient's blood volume as soon as possible: We use drugs such as infusion and blood transfusion. What we have to do at the first scene is to let the patient lie flat and wait quietly for the arrival of emergency personnel.

Second degree burns can be divided into shallow second degree and deep second degree. Shallow second-degree injury of dermis, blisters, edema and pain on the skin. If there is no infection, it usually heals in about 2 weeks without leaving scars. Deep second degree and deep dermis, pale and grayish white skin with erythema in the middle, local tissue necrosis, prone to infection, usually 3-4 weeks, can leave scars.

Third-degree burn, complete necrosis of cortex, even coagulative necrosis of deep tissue, dark complexion, hardness and tenacity, loss of elasticity, loss of sensation, dry surface, liquefaction under eschar after 2-3 weeks, easy to be infected, very slow healing, and serious scar after healing. 3, symptoms: initial * * * shouting, fear, mental tension, severe irritability, severe cases can enter a state of shock.

4. First-aid treatment: First of all, try to put out the flames of the injured in the on-site first aid and organize the injured to save themselves. You can cover a quilt, blanket, etc.

Or douse it with water and quickly take off the burning clothes. If you can't get it off, cut it with scissors in time to prevent the burn from getting worse. Then wrap the injured part or the whole body with clean cloth and quickly send it to a nearby hospital for treatment. Injection of dolantin to relieve pain; Early injection of tetanus antitoxin; Intravenous infusion, blood transfusion, anti-shock treatment and anti-infection treatment; Symptomatic and wound treatment. 5. Chemical burns: Simply put, strong acid, strong alkali and phosphorus burns are washed with plenty of water first, and then sent to the hospital for emergency treatment.

Verb (abbreviation of verb) First aid for fracture, contusion and sprain 1. Unique signs of fracture: deformity and morphological changes of injured limbs after displacement of fracture segments. Abnormal movement, where there are no joints in the limbs, there may be abnormal movement after fracture.

Bone friction sound or bone friction feeling. As long as one of the above three is found, a diagnosis can be made.

2. First aid: The purpose of fracture first aid treatment is to save lives and protect injured limbs. The method is simple and effective. It can be safely and quickly transported to the hospital for proper treatment.

General treatment: all students suspected of fracture should quickly pass a brief key examination to understand the injury and all actions should be safe. Wound dressing; Correct fixation can prevent the fracture end from rotating during handling and causing greater damage to soft tissues, blood vessels, nerves or internal organs, and immediately relieve pain and transport after fixation.
