Weakness in hand grip is mainly characterized by a lack of strength when holding an object in the hand. Weakness in hand grip can be caused by conditions such as nerve entrapment syndrome of the hand, pre-spinal cord syndrome, cervical spondylosis, and tennis elbow. Nerve entrapment syndrome is one of the bone-fiber canal and compartment compression syndromes. For the peripheral nerve line a certain part of the bone fibrous tube, a few for the fiber edge is compressed and chronic injury caused by inflammatory reaction, resulting in abnormal nerve function. Hand trauma is a common cause of hand grip weakness, so be sure to pay attention to prevention. Burns Rarely next time in the kitchen, so inexperienced. If you accidentally splash hot oil or boiling water on your hands, accidentally touch the wall of a pot that is heating up, or open the lid of a pressure cooker without waiting for it to run out of gas, your hands will suffer. What can be done to prevent hand trauma in this situation? If there is a small area of redness on the skin, it is not a serious injury and is a first-degree burn. If the injured area blisters and the pain is more serious, it is II degree. The most effective method, rapid local cooling, rinse with clean cold water or ice packs, continued until the pain is significantly reduced, to prevent the expansion of the injured surface, to stop the injury aggravated, and then local application of burn cream. Do not squeeze the blisters on the injured surface, the small ones will absorb by themselves, and the big ones can be used to poke an eye in the lowest part of the blister with a sterilized needle to squeeze out the accumulated fluid. Once the color of the skin on the hand becomes black or brownish-yellow, the pain is rather reduced, but it has reached III degree burn. Never rinse with water as it is prone to infection. Don’t rub soy sauce or sprinkle table salt on the wound either, as they may also have bacteria, making the wound worse. The right way is to cover the burned surface with sterilized gauze (sterilized paper towels can be used instead), bandage it, and then go to the hospital or call 120, which is a much better way for the doctor to handle it. Skin Bruises The daily job of the hand is to touch here and move there. When the body’s commanding brain is distracted and the hand happens to touch an object with a rough surface, it can bruise, causing instant pain, followed by blood oozing or capillary bleeding. At this time, you need to immediately use alcohol, soapy water or water to clean the soil on the wound. Bleeding more, need to use cotton balls or gauze (clean handkerchiefs or toilet paper can also be) pressed in the wound for a few minutes, to not bleed when the purple potion coated in the wound to do a good job of hand injury prevention. Generally not deep wounds do not need to be bandaged, wound exposure is more conducive to wound healing. After the soil is cleaned, the wound should not be exposed to water for the time being, after a few hours or the next day, you will find that there is a bright liquid oozing out, you can use a physical therapy lamp or desk lamp to bake on the wound for about 10 minutes, 3 to 5 days to heal. If the wound is too deep, it is better to seek medical help. Prick wounds Traveling outside, especially backpacking, destinations are undeveloped tourist landscapes. Fingers can easily be pricked by wooden thorns and plant leaf thorns. After being stabbed, do not be concerned about the size of the wound and how much bleeding, the important thing is to determine whether there are broken thorns left in the wound. If there is, first try to pull it out. Sterilize the area around the wound with alcohol, and use tweezers that have been sterilized by fire or alcohol to try to remove the splinter intact. If the exposed part of the thorn is too short for the forceps to hold, use a sterilized needle to open the skin of the wound, widen the wound appropriately so that the thorn is exposed as much as possible, and then hold it and gently pull it outward. After confirming that there is no stinger, gently squeeze the wound to squeeze out the stasis and minimize the chance of re-infection. Finally, disinfect the area around the wound once with iodine and twice with alcohol, and bandage it with sterile gauze. If you are still unsure, take Synthroid to prevent inflammation. Once the splinter is in the nail, cut the nail into a V-shape in order to pull out the splinter. If the wound is deep and narrow, it is best to get a tetanus antitoxin (TAT) injection within 24 hours to prevent tetanus bacteria from invading the body. Cuts There is no need to be overly alarmed by a cut caused by a sharp, sharp instrument such as a pocket knife or kitchen knife that causes heavy bleeding. If the cutter is not clean, rinse the wound with clean water and wrap it in gauze. If the blood continues to ooze out slowly, wrap the gauze slightly thicker and tie a tight bandage around the injury. Raise your hand higher than your heart to help stop the bleeding. If blood is gushing out, press the blood vessels on both sides of the finger near the heart, or tie the blood vessels at the base of the finger with rubber tubing or string. Keep in mind, long time tie too tight will make the finger ischemia, or even necrosis, so every 20 ~ 40 minutes should be loosened. Cutting Nails that are cut too “bald” may crack and bleed. Stir honey into half of warm water and apply a few times a day. During this period, if you play tennis, basketball, before the movement must be used to rubber bandage the finger end of the package 2-3 layers to protect, immediately removed after the ball, so as to avoid infection do a good job of hand trauma prevention. If it is bleeding under the nail bed, the blood can not flow out, the root of the nail bed bulging, will be painful and can not sleep. You can use a red-hot sewing needle to make a small hole near the root of the nail to drain the blood, sterilize it, and then bandage the nail with pressure. People with a history of bleeding from cracked nails should eat more foods containing more vitamin A in their daily diet, such as cabbage, radish, leek, and pig liver, to increase the elasticity of the skin and nails.
