Master the three steps of hemostasis, ice preservation and drug treatment, and there will be "hope" to save the severed limb. 1 Mr. Zhang, who works in a factory, accidentally amputated his right finger at work. Fortunately, he stopped bleeding in time, frozen the severed limb and rushed to the hospital, and the severed finger was successfully retrieved. The doctor said that in case of an accident, remember not to throw the broken limb directly into the water, because the swollen tissue after soaking in water will increase the difficulty of microsurgery.

Dr. Lin Youcheng, a plastic surgeon at Douliucheng University Hospital, said that in the event of limb amputation, remember to master three steps: hemostasis, ice compress and medical treatment.

Due to proper disposal, the first finger, middle finger and ring finger were successfully retrieved after 8 hours of microsurgery.

Cryotherapy can prolong the survival time to 24 hours.

Dr. Lin Youcheng pointed out that finger amputation is the most common limb amputation, which is mainly caused by careless mechanical operation at work; Followed by accidents such as traffic accidents. Generally speaking, exfoliated body tissues usually die at room temperature or in a warm environment without blood supply 12 hours. If the severed limb is replanted after 12 hours, the chance of successful operation is low.

If the exfoliated tissue is frozen at 4 degrees Celsius, it can survive for 24 hours. It is particularly important to note that if the exfoliated tissue contains muscle tissue, the storage period at room temperature or warm environment is about 6 hours, because muscle tissue is easy to necrosis; If the limb is frozen, it can be extended to 12 hours.
