After the winter temperature plummeted, especially in the second half of the night, the temperature hit a new low in winter, close to 0 ℃, last night in the second half of the night to send a noodle stirring inadvertently stuck in the stirring machine was churning trauma patients, the injured person’s left hand skin peeled off all the time, the blood burnt. Recently, in the early hours of the morning, we often come across patients with disarticulation injuries who were churned by the noodle churn, which has a gap in the blade of the churn, and in the event of an accident, the patient would instinctively pull his hand back, thus causing extensive contusions. Dehiscence injuries are serious injuries in which roller-type machinery tears away soft tissues, often accompanied by neurovascular and tendon avulsions, and wounds such as these are associated with poorer joint recovery. In addition, there is an increase in the number of patients with chainsaw injuries. 63-year-old Wu Dabo used a chainsaw to crackle firewood at home, resulting in severe cuts to the left wrist by the chainsaw, radial tissue defects, the tissues sawed off by the chainsaw were severely damaged and could not be utilized. After the sawed off tissue was severely damaged and could not be utilized, the tissue was taken from the right thigh for anastomosis of blood vessels and free tissue transplantation. Fortunately, the surgery was timely or Wu’s left hand might not have been saved. Due to the sudden increase in the number of patients with hand trauma, the Department of Plastic and Reconstructive Surgery’s emergency phone calls were frequent in the middle of the night. The day before yesterday, the operation lasted 12 hours, five patients, two of which were free tissue graft repair. The analysis of the first may be that the temperature is low and the hands are not sharp enough to work, and the second is that people working in the early hours of the morning do not have enough concentration. Therefore, it is recommended that early morning operators must concentrate to prevent the recurrence of such accidents. If an accident occurs, it must be sent to the hospital as soon as possible surgery. What is the most appropriate way to handle hand trauma at home? Hand injuries are most common in life. Hand trauma can occur when you are not careful in the kitchen. It is understood that in the major hospitals emergency surgery, the proportion of hand trauma on holidays accounted for more than 30%, of which the majority of knife cuts. If you accidentally hand injury, how to deal with it before going to the hospital? The first step, stop bleeding. General bleeding, with clean gauze or handkerchiefs, towels in the bleeding part of the pressure bandage can be, you can also use the other hand or by someone else on the injured hand pressure, both effective, but also will not cause adverse consequences. If arterial injury occurs hemorrhage, available tourniquet or elastic cowhide tendon binding upper arm 1/3 parts of the bleeding, and immediately go to the hospital, if the distance should pay attention to every hour to release the tourniquet 5-10 minutes, so as to avoid ischemic necrosis of the hand. The second step is to prevent further contamination. Do not apply purple potion and other drugs on the wound, so as not to affect the doctor’s judgment of the injury. Step 3, prevent aggravation of the injury. If a finger fracture occurs, use a small wooden board, iron and other temporary fixation, but also can play a role in pain relief. If a broken finger or hand, do not discard the severed limb, to use gauze or a clean towel wrapped severed finger or hand, covered with a plastic bag, put some ice or ice lolly outside the bag, as soon as possible to the hospital, and strive for re-implantation surgery within 6-8 hours. Never immerse the broken finger or hand into alcohol, disinfectant water, saline and other liquids for transit, so as not to destroy the tissue structure of the broken finger or hand, affecting the survival rate of reimplantation. In addition, for some small hand trauma, if you have a standing first aid tool at home, you can dispose of it by yourself. If the hand is crushed by a heavy object, most of the skin will not be broken, but the appearance of subcutaneous bruising or hematoma, at this time to use a cold towel or cold water bag of external compresses for about half an hour, can prevent the hematoma from increasing, reduce pain.
