Sometimes you feel that the danger is far away from you, but in fact there are always some accidents in life. Do you know what to do with them when they appear?
Q: What will you do when you first encounter a broken finger/palm?
Many people may answer: hurry to the hospital!
But if you ignore some details, you may regret it for a lifetime.
He almost lost his palm!
Mr. Chen in Shenzhen was stabbed in the right hand by a steel wire and his blood vessel was pulled out ... but he "saved himself" and his palm for the first time!
The palm of your hand is almost cut off by the steel bar.
Time cannot be delayed!
On that day, when Mr. Chen (pseudonym), 48, was working on the construction site as usual, he was accidentally entangled in the palm of his right hand by a large piece of steel wire, and his right hand was immediately caught by the steel wire, resulting in amputation of his four fingers, avulsion of his skin tendon, and tearing of his finger blood vessels. Mr. Chen managed to dress the wound and went to Peking University Shenzhen Hospital for treatment.
Zhou Zhegang, deputy chief physician of hand microsurgery in Shenzhen Hospital, Peking University, found that this is the most serious "torsion tear detachment" in hand surgery! Because Mr. Chen has been in hospital for three hours, and it usually takes eight hours for his fingers to leave his limbs, he will die if he loses blood supply and oxygen supply. There is not much time left for the doctor! The hospital immediately opened a green channel for patients.
Please see a doctor urgently within 8 hours? The shorter the time, the more likely you are to recover.
Amputation? In situ replantation? Refuse! You can also have this option.
According to Director Zhou, severe twisting and tearing like Mr. Chen usually requires amputation or replantation in situ.
However, the middle part of the patient's palm was twisted into pieces.
If replanted in situ, it is necessary to debride and remove the proximal finger and metacarpal bone, and then connect the remaining half finger to the middle of the palm. In this case, even if replanted, the patient's palm will be shortened by about 6 cm, which looks extremely weird and deformed, which is of little significance to the functional recovery of the palm and fingers, and will cause a double psychological and physical blow to the patient.
Therefore, hand surgery decided to do "heterotopic foster care" surgery for Mr. Chen.
Put on a live-action version of Parasitic Beast? The third stage operation successfully replanted the severed finger.
Considering that the diameters of blood vessels in the palm and instep are relatively the same, transplanting the instep vascular network into the hand in the later period will basically not affect the function of instep. Hand surgery decided to "foster" Mr. Chen's severed finger on the instep after consultation.
Can you do it?
Stage 1: Connect finger blood vessels and instep blood vessels.
Because the blood vessels on the fingers and instep are extremely slender, the microsurgical skills of doctors are extremely demanding. The whole operation was performed under a microscope, and the doctors finally spent 10 hours, and successfully connected 10 blood vessels all night.
Stage 2: Fingers "foster" on the instep for half a month and then survive.
Because Mr. Chen suffered a serious injury in the middle of his palm, he needed palm flap surgery to replant his severed finger. The doctor reconstructed the soft tissue of Mr. Chen's severed palm stump to repair the skin defect.
The third stage: finger foster care after 1 month.
The most risky "replantation" operation needs to be cut layer by layer along the vascular network without destroying the vascular network of Foster's fingers and feet, looking for a long enough vascular pedicle, just like a twisted kite string. Once the thread is cut wrong, other kites will be cut.
Once something goes wrong in this process, the previous 1 month of surgery and preparation is equivalent to doing nothing. Finally, with superb medical skills, the hand surgery team successfully dissected a blood vessel with a length of about 12cm within 8 hours, and successfully replanted the "Foster" finger into the palm.
Mr. Chen (a pseudonym) can write with his right hand.
One week after operation, the finger survived successfully. After later functional exercise, Mr. Chen's right hand can already write with things.
I like the superb skills of doctors!
