"One of the main functions of plaster is to fix."

For patients with fractures or tendon ruptures, it is more conducive to wound healing and repair than simple splinting.

In particular, some open wounds, if they have not healed, the soft tissues should not be compressed, and they are not suitable for splinting to fix.

If you want to avoid damage to the greatest extent and reduce the burden of human activities, and do not want to bring inconvenience to your movements, gypsum is a better choice.

After listening to Ji's words, Xin Ziqi silently put back the splint he had just taken out.

After hesitating, he pointed to the thing in her hand: "Then you ......"

"This is a plaster bandage for immobilization."

The so-called gypsum bandage is actually made of starched gauze and cooked gypsum powder. Soaked in water and bound to the affected area, it can harden and shape in a short time, and has a strong shaping ability.

"I thought you wanted gypsum powder because you wanted to use it externally, or to mix it into a paste."

"Gypsum powder does have the effect of building muscle and stopping bleeding, but it does not conflict with gypsum bandages. And your family's special hemostatic medicine is very useful, the homeless's bleeding has stopped, and the top priority is to fix him. ”

Xin Ziqi looked at the plaster bandage in her hand, but the plaster bandage that was a little thicker than ordinary cotton yarn was a little unimaginable, how could this be compared to a splint?

Ji didn't talk nonsense, and directly asked Ping An to bring a basin of warm water.

"Look at it, this is very useful for your orthopedic department, it can not only fix the injured limb and prevent the re-injury of tendons and blood vessels, but also correct deformities and maintain functional positions......

The two discussed it for a while and decided to immobilize only the right and left feet, where the tendon had been completely ruptured.

Ji walked over to the homeless man who was lying flat.

Since there were no plaster scissors, when she came to deliver the meal last night, she measured in advance how long the gauze would be needed in each place, and only then began to make plaster bandages when she returned, so the size difference was not large.

First sew out the thin cotton cover that worked overtime last night. Slip it on, make sure it is three to five centimeters above the fixed border, and wrap it in another layer of padding.

"What is this?" The Xinzi period is incomprehensible.

"Plaster is not elastic and does not have a padding, which can easily cause tissue crushing. The padding prevents crushing injuries and protects the skin of the bony carina from bedsores. ”

Ji answered his question as he tilted a certain amount of the bandage roll at an angle of forty-five degrees and immersed it in warm water.

In the calm basin, a large number of bubbles quickly bubble up.

Wrap your hands in a tarpaulin and squeeze them in the water for two to three seconds until no continuous bubbles are formed. Remove the bandage and gently press your hands towards the middle to squeeze out any excess water.

Next, adjust the limb position. Make sure your fingers are half-flexed, your thumbs are facing your palm, and your wrists are dorsally extended at 30 degrees.

Then, hold the plaster roll with your right hand and place the beginning of the plaster roll on your arm with your left hand.

"It is necessary to focus on fixing the proximal joint of the injured part to prevent the injured part from being repeatedly stretched during joint flexion and extension, which will not only affect healing, but also lead to aggravation of swelling and pain."

Alternate the two hands, from the proximal to the distal side of the limb, in a rolling fashion, in a spiral and even wrap around the bandage.

Wrap the elbow joint in a figure of 8, and when wrapping to the last layer, fold the top of the thin cotton sleeve backwards to avoid damage to the skin by the edge of the plaster bandage.

"Each lap overlaps by one-third to two-thirds so that it condenses into a whole. At the same time, it is necessary to ensure that the tightness is moderate. Too loose will weaken the adhesion of the bandage, and too tight will affect blood circulation in the affected area. ”

The whole season is explained, and while bandaging, don't forget to level it with your hands. This increases the adhesion between the layers of the bandage and avoids wrinkles, especially when wrapping the first two layers.

Of course, if you have latex gloves, wear the gloves with wet water to shape it, so that the bond between the layers is tighter and smoother.

After the bandaging is completed, the outermost layer is temporarily reinforced with an ordinary gauze bandage.

"Remember to do it quickly, preferably in an instant, otherwise the plaster cast will harden and will no longer be usable."

Xin Ziqi stared at it with good eyes, and after a while, the bandage that almost wrapped around his entire arm gradually became harder.

After touching it, this all-round fixation is indeed more reliable than a splint.

"That's it...... Dip it and it's done? The tone was rather surprised.

Ji has already put a cotton sleeve on the homeless man's left leg, and is now adjusting the angle.

Seeing this, Xin Ziqi walked over to help, and observed by the way.

"Impregnation is also exquisite. The water temperature must be between 25 and 30 degrees...... Well, you can sense it with your hands. The maceration time is about a dozen breaths, so it is important to complete the shaping within the operation time, otherwise the adhesion and shaping effect will be affected. ”

"Will he be able to move after that?"

"You can't move freely for a quarter of an hour before the bandage is completely hardened, and then you can do small movements if the wound doesn't hurt."

"If it's all-round fixation, why don't the fingers and toes cover it?"

"The fingers and toes are exposed so that the blood circulation at the ends of the limbs can be observed...... You can also use it as a convenient post-workout. ”

"I see."

Xin Ziqi wrote down the main points one by one, and went to observe the bandages on the homeless man's arms.

Ji felt a slight regret in his heart.

Gypsum bandages are inconvenient to use, and in modern times, they have been gradually replaced by polymer bandages and medical polymer splints.

Polymer bandages do not have skin tightness and itchiness after drying, as well as skin hot flashes and itching caused by poor air permeability, which is conducive to skin metabolism and has the effect of waterproofing.

And hardening is extremely fast. Curing starts in two to three minutes, hardening starts in three to five minutes, and it can be load-bearing after twenty minutes.

It's a pity that no matter how many advantages you have, it's useless, and it's good to be able to get a plaster bandage right now.

Ji patted the homeless man's leg and asked him to raise as high as possible.

Shortly after the operation, the homeless man was visibly weak, but he still cooperated.

Because the tension of the Achilles tendon is minimal, in order to ensure tension-free healing of the Achilles tendon, the knee joint is fixed at 20 to 25 degrees of flexion.

Compared to the eighth layer of the right arm, the left leg does not stop until the twelfth layer.

Ji thought about it again, although the right leg was not completely broken and basically healed, but after all, Xin Ziqi also gave a few stitches, so it is better to bandage it, but you can do it at will.

After all the processing was completed, Ji found a piece of blackened charcoal and marked the date of dismantling the plaster on the plaster.

"It takes a month?"

Ji nodded: "It's just the right leg, the left leg and the right hand time will be extended." ”

Xin Ziqi still has a doubt: "Then how should he change the medicine?" ”

"Hmm...... Let's see if you can open the window. ”

Ji explained to Xin Ziqi what it means to open a window.

You can use a saw when you go to the plaster, and it will be troublesome to open the window, so go back and ask someone to see if there are any other tools.

Ping An probed his brain outside.

Seeing that the two people in the room had noticed him, he laughed a few times: "Young master, it's not early, when will we go back?" ”

"Tonight...... Not back. ”

Ji, who was waiting for Xin Ziqi's answer next to him, secretly breathed a sigh of relief.
