The sooner the patient is injured, the better, and strive for replantation within 6-8 hours. The correct preservation of severed fingers is the basis and premise of successful replantation of severed fingers.
After the severed limbs and fingers, although they lost blood nourishment, they still have vitality in the short term, but over time, they degenerate and rot. Therefore, it is still possible to replant the severed finger if we can master the correct method of preserving it.
Situation one
Incomplete limb: transport with splint braking to avoid aggravating tissue damage.
Situation 2
Complete amputation: wrapped in sterile and moist physiological saline gauze, wrapped in clean dry gauze, and refrigerated at 4 degrees.
If the transfer time is long, you can wrap the severed finger with clean cloth, put it in a non-porous plastic bag and put it in a thermos with ice cubes for refrigeration. It is difficult to get ice for a while, so you can use popsicles and ice cream instead, or you can quickly transfer to a hospital with replanting conditions.
Be sure to avoid soaking the broken finger in any liquid! Never put the severed finger into alcohol, disinfectant, salt water, ice water, etc. It will destroy the tissue structure of severed fingers and affect the survival rate of replantation.
Common error demonstration
1, put the severed finger in ice water to cool down and reduce metabolism, but I don't know that this will actually frostbite the severed finger and reduce the success rate of surgery.
2. Alcohol can denature protein, so it is forbidden to directly soak the severed limb (finger) in alcohol.
The correct way: if you want to rinse, you can only use physiological saline.
First aid steps
First aid method of severed finger (limb)
0 1 "> First of all, pay attention to whether the wounded have shock or other complicated injuries. In case of shock or other life-threatening complex injuries, you should be rescued quickly.
Section 02 If there is active bleeding, apply a clean dressing to pressurize and bandage the bleeding, and bandage the bleeding forcibly; It is best not to use a tourniquet. If a tourniquet must be used, the tourniquet should be loosened once every hour with an interval of 10- 15 minutes, so as not to aggravate the injury for too long.
Most of the broken limbs should be fixed before transfer to avoid injury during transfer.
The completely amputated limb should be kept in sterile dressing or clean cloth, towel and other bags at low temperature (ice cubes should be placed around, but liquid should not be soaked) and sent to the hospital as soon as possible.
In the process of transfer, try to get in touch with the hospital at the same time and make preparations for acceptance.
