How to get first aid from a spider bite

After being bitten by spiders, the following methods should be taken for first aid: 1. If the bitten site is located in the limbs, immediately tie the wound near the heart with a rope or soft cloth to prevent the spread of toxins. 2. Squeeze the wound hard to squeeze out the contaminated blood and toxins, and then rinse the wound with plenty of water. If conditions permit, you can wash the wound with alkaline sodium bicarbonate water or soapy water, because the venom of spiders is acidic, which can neutralize the toxins. 3. If the skin around the wound is red, swollen, painful and other manifestations, hydrocortisone ointment can be applied to the affected area, which can effectively relieve the symptoms. If accompanied by strong itching, azelastine hydrochloride tablets can also be taken orally. 4. Go to the dermatology department of the hospital quickly, because some spiders are more toxic and can cause death.
