The importance of hands and feet to people cannot be overstated, but with the widespread use of industrial and agricultural machinery, the incidence of traumatic hand and foot injuries is increasing. Hand and foot trauma accounts for about one-half of the number of orthopedic emergency patients seen, and it is a shame to see cases in which improper pre-hospital management leads to increased surgical difficulty and even loss of hope for cure. The following are a few of the most common misconceptions: Misconception 1: Blind bandage After a trauma is usually accompanied by wound bleeding, many patients will come to the hospital with a bandage or towel on the spot, thinking that this can reduce bleeding. In fact, this is a wrong viewpoint. The bandage can only block the superficial venous reflux, but not the arterial blood flow, which will make the wound bleed more seriously. The easiest and effective method to stop bleeding in hand trauma should be local pressure bandage, even if combined with large artery injury, the pressure bandage method can generally achieve the purpose of stopping bleeding. Misconception 2: Inappropriate bandage After trauma bleeding, patients often use toilet paper for local bandage. In fact, most toilet paper is not hygienic, and the paper material will soften when it sees blood, making it more difficult to clean the wound and increasing the risk of infection. It is relatively better to choose a clean cloth for on-site bandaging, which can not only stop bleeding by compression, but also reduce the chance of contamination. Misconception 3: Local medication When dealing with smaller wounds, it is common for patients to put powdered agents such as sulfonamide powder on the wound, thinking that this can play an anti-inflammatory role, but in fact, sulfonamide powder mixed with blood will form a scab to stop bleeding in the short term, but because the wound is not thoroughly cleaned, bacteria multiply and often pus accumulates under the scab, affecting wound healing and even leading to deep infection. When hand and foot trauma occurs, you should go to a regular medical institution as soon as possible for debridement treatment. Some patients with severed limbs (fingers) soak them in ice, alcohol or saline before consulting the doctor. The correct method is to apply local dressing to stop bleeding, wrap the amputated limb (finger) with a sterile dressing, place an ice pack around it, and send it to a hospital that is qualified to perform replantation surgery as soon as possible. Myth 5: No local braking Some patients with fractures or incomplete severed limbs (fingers) are not braked on the way of transportation, which may cause further damage to blood vessels and nerves, and in serious cases, may lead to the loss of replantation conditions. Therefore, it should be immobilized with a splint prior to transport.
