Cutting vegetables cut off the little thumb should be immediately after the initial hemostasis, and then immediately consult the hospital general surgery emergency for further treatment. Due to the rich blood flow of the finger, after the little thumb is cut off, it should be immediately compressed on both sides of the finger to stop the bleeding of the finger marginal artery, use clean water to quickly rinse the severed end of the finger, and stop the bleeding of the proximal end of the severed finger by ligating it with a bandage of cloth and other ligatures. The hemostatic ligature should be released for 1-2 minutes every 60 minutes to avoid ischemic necrosis. After the initial hemostasis, immediately consult the emergency department of the hospital. The severed finger also needs to be rinsed quickly with water and sealed in a clean plastic bag placed in ice for preservation. Carry the 4 ℃ cryopreserved severed finger to the hospital with the conditions of the severed finger reimplantation, and carry out debridement and suturing and other treatments.
