The last and most important step is to test the replantation effect of the free flap.

The circulating nurse opened the tourniquet valve.

The deflation was completed quickly.

Everyone leaned forward.

The color of the skin flap gradually turned redder, visibly to the naked eye.

"Haha, it worked!" Bao Youshan said excitedly. The harvest from today's operation was huge.

Everyone looked at it and nodded.

"Not only did the skin flap regain its red color, but the fingers also regained their redness. The sutures of both sets of arteries and veins were very successful!" Zhu Qidong concluded.

Li Zheng used the syringe needle to prick several needles around the skin flap, and soon drops of blood oozed out.

This indicates that the entire flap has a rich blood supply.

"Plaster preparation."

Li Zheng began to bandage the wound.

Bao Youshan was very proactive and directly wrapped the entire skin flap with gauze.

"It's not appropriate to bandage like this." Li Zheng stopped it in time.

Bao Youshan was stunned. Are there any particular requirements for bandaging?

Everyone was also curious about how to bandage it.

Li Zheng explained, "The blood flow of the flap must be monitored, so the bandage needs to leave an observation window and cannot cover the entire area. Furthermore, the finger has undergone a blood vessel transplant, so it cannot be bandaged in a circular pattern. This is because the exudate will make the gauze hard, and the bandage may become tighter and tighter, blocking blood circulation."

When everyone heard this, they suddenly understood.

"Tsk tsk, this operation is really full of details and traps!" Director Zhang sighed.

"Microsurgery is a very delicate subject. A rough person can't do it well!" Zhu Qidong said proudly.

"Look how proud you are!" Duan Jianhui said with a smile.
