Everyone should understand some basic family first aid knowledge, just in case. During the first aid process, some situations should be taken seriously.
1、 The tourniquet should not be tied for a long time. When using cloth strips or gauze as a tourniquet, the tourniquet should not be too thin or too narrow, and should not be directly tied to the skin. A cloth should be placed between the tourniquet and the skin (such as gauze, towels, or sleeves). The tightness of the tourniquet should be appropriate, and it should be loosened every 30 to 60 minutes for 2 to 3 minutes (using finger pressure instead of hemostasis) to avoid ischemic necrosis of the limbs below the tourniquet.
2、 Small and deep wounds should not be immediately bandaged, especially after being punctured by rust nails or wooden thorns, or due to glass damage, the wound may lack oxygen. If bandaged immediately, it will be beneficial for the growth and reproduction of tetanus bacteria. You should go to the hospital for debridement and injection of tetanus antitoxin.
3、 Comatose patients with severe inhibition of advanced neural activity should be closely observed and carefully cared for. Patients should not drink water or eat before waking up, otherwise food or water may accidentally enter the trachea, causing inhalation pneumonia and even suffocation and death. So, comatose patients should absolutely fast, but they can use a cotton swab dipped in water to moisten their lips.
4、 Skin contact with pesticides should not be washed with hot water or alcohol, as it can promote the absorption of toxins. Contaminated clothing (including underwear), gloves, shoes, socks, etc. should be immediately removed, and toxic substances on the skin and hair should be thoroughly rinsed with soapy water or 1%, 5% sodium bicarbonate solution.
5、 Acute abdominal pain has an acute onset, multiple changes, and rapid development. If not treated in a timely manner, it can endanger life in the short term. It is necessary to go to the hospital for diagnosis and correct treatment in a timely manner. For patients whose diagnosis is difficult to determine at the moment, it is not advisable to take strong painkillers (such as painkillers, Qiangtongding, morphine, Du Lengding, etc.), and laxatives and enemas are prohibited. Otherwise, it will mask the condition, delay diagnosis, or worsen the condition. Wait for examination and diagnosis before proceeding with treatment.
