Chapter 542 Safety Accident
Of course, Sun Li'en and Cao Yanhua were not the only ones in the emergency room.However, Cao Yanhua is currently the only chief resident physician on duty. Although the other resident physicians are not inferior to Sun Lien in terms of rescue, Sun Lien's diagnostic expertise can get more full play.

A limb amputation is an injury that needs to be taken very seriously.However, unlike other degloving injuries and avulsion injuries, the purpose of highly serious limb amputation is to save limbs.

In fact, Sun Li'en was also a little bit guilty, this evening is really a bit of a trick - a leg injury followed by an upper extremity injury, the orthopedics department will be quite busy tonight.

Being able to be diagnosed as a severed injury rather than a damaged injury before the hospital means that this patient who has not yet arrived at the hospital has a high probability of receiving a severed limb replantation.Unlike blunt avulsions, which can cause serious nerve and muscle damage, and unlike mutilation injuries, which are hopeless injuries at all, amputation injuries generally mean that although the limbs are completely separated, they are caused by sharp cutting. Injury, so the cross-section of the broken wound is generally smooth.This often also means that there is not too much damage to the nerves and blood vessels and even the muscles.Doctors can try to reconnect the completely severed nerves and blood vessels through surgery, and suture the muscles, so as to partially restore the function of the limb.

Because it is more promising than other injuries, hospitals often take the highest degree of attention to patients who are determined to be broken.The more important reason is that there is a window of time for the repair of this broken injury.

Since the severed limb was physically separated, it immediately fell into a state of no blood flow.The muscle cells and nerve cells that make up the limbs all need oxygen to survive.Without blood flow, there is no oxygen.They can't live without oxygen—it's that simple.If the anaerobic state persists for too long and the number of dead cells becomes too high, the limb can never be reattached—the dead cells release large amounts of potassium and other cellular contents that are toxic to the body.If such a stump is connected back to the body, the potassium and toxic cellular contents will return to the patient's body through the veins, not to mention how much function the stump can retain, the potassium alone can It directly causes cardiac arrest and kills people.

Therefore, this time window is generally six hours.But in Ningyuan at the end of June, the average temperature has risen to close to 29 degrees. Under such conditions, if the severed limbs are not properly preserved, the window period will be shortened to about four hours.

Sun Li'en and three nurses stood guard at the door of the rescue hall, praying with all his heart, hoping that the pre-hospital first aid had taken sufficient measures to deal with and protect the residual limbs.Let's hope it doesn't take more than four hours.Let's hope the stump pollution isn't too serious.

Today there is already a patient who definitely needs amputation, and he doesn't want to see another poor person who needs amputation.

The ambulance appeared at the rescue passage of the Fourth Hospital with a loud voice, and then stopped abruptly at the door of the rescue hall with the sound of sharp tires rubbing against the ground.Sun Li'en quickly greeted him with three nurses, and then quickly prepared to transfer the patient.

"The broken limb is here." A middle-aged man jumped out of the car with a large white plastic foam box, and stuffed the box into Sun Li'en's hands without any explanation, "Doctor, take a quick look, can this still work?" Can you pick it up?"

"How long has it been since you were injured?" Of course, Sun Lien, who was holding a big plastic foam box in his hand, couldn't help pushing the cart, but he quickly calmed down, asked about the situation, and opened the foam box to look inside One glance, "Is there ice cubes in here?"

"I let it go, I was injured... I was injured for about half an hour." The middle-aged man wiped the sweat from his head and nodded, "I put ice cubes under the box, then wrapped the legs with several layers of clean cotton cloth, and Put it in a thick plastic bag, and then put it in." He asked anxiously, "Doctor, can this leg be connected?"

Sun Li'en took a rough look and found that the severed limbs were indeed separated by plastic bags and ice cubes at the bottom of the foam box.The top of the plastic bag was deliberately pricked, and judging from the feel of the plastic bag, it was indeed wrapped in cotton cloth.He nodded, and while following the emergency bed to the hospital, he replied, "Your method of preservation is fine, and there is hope of taking it back. How about the specific situation, I have to let the orthopedic doctor take a look."

In the emergency room, Zheng Guoyou, director of the orthopedics department, had long been standing in front of the duty desk.After seeing the rescue bed and Sun Li'en running in with a foam box in his arms, Lao Zheng unceremoniously stopped the bed, lifted the thin blanket and looked at the wound, then nodded, "The wound is in good condition, very clean. He looked at Sun Lien and asked, "Are severed limbs inside?"

Sun Li'en nodded, and put the foam box on the table beside him, "Director Zheng, can you take a look now?"

"That must be watching now." Zheng Guo nodded, took off the latex gloves on his hands, and took out a new pair of gloves from the duty desk next to him, "Open it and let me see."

Sun Li'en carefully opened the thick black plastic bag, and Zheng Guoyou took out a leg wrapped in cotton cloth without hesitation, "The bag is okay, it's about three centimeters above the knee joint, not bad, the joint is fine." How did you get hurt?" He tore off a bit of the cotton cloth, then touched the leg with the back of his hand and asked, "The injury lasted about an hour?"

"Almost." The middle-aged man nodded, "Doctor, can this leg be connected?"

"Of course it can." Zheng Guoyou gave a more direct and affirmative answer, "The question now is just how much function he can recover after the leg is reattached." He lowered his head and looked over the lens at the Middle-aged man, "It's impossible to fully restore function, but walking with a cane should be fine. Whether he can recover better depends on his perseverance and luck." Speaking of this, Zheng Guoyou The injured leg was handed over to the orthopedic doctor on the side, and he asked the other party to perform preliminary debridement on the wound of the severed limb, and then take the patient to take an X-ray to check the bone damage, and then he said to the middle-aged man, " Tell me, how did it hurt?"

The middle-aged man sighed, pointed at the young man lying on the hospital bed and said, "This is my nephew..."

Wu Lian just graduated from university this year, but because the school is not very good, and it has been very difficult to find a job in the field of finance in recent years, so after much deliberation, he decided to come to Ningyuan to join his uncle Wu Zhong.My uncle opened a glass factory in Ningyuan. Although he can't do work related to his profession even if he comes to the factory, he is working for his relatives after all, so the family can rest assured.

Wu Lian is a serious and hardworking kid. Apart from doing accounting work in the factory, he will do other jobs as long as he can do them.From glass cutting to loading, sometimes he even acts as a delivery driver - Wu Lian has a B1 driver's license.

Today, however, the factory received an urgent order.A construction site far away in Changning is a major customer of the factory, but in the early hours of this morning, Wu Zhong received a call from the major customer - among the glass curtain wall components they provided to the construction site before, there was an eight-meter-by-six-meter The large tempered glass was smashed by construction machinery.According to the construction plan, this piece of glass must be installed in place this afternoon.

Generally speaking, as long as the requirements of major customers can be realized, Wu Zhong will do everything in his power to do so.What's more, this order is an urgent order, and the price is 70% higher than the usual quotation.After receiving the call, Wu Zhong rushed back to the factory immediately, and called the truck to prepare for hoisting.

However, the problem lies in the installation.Because there is only the last piece of tempered glass of this size left, everything must be safe during installation.Wu Lian, who lived in the factory, volunteered to be responsible for the lower pulling work of the hoisting.

Unfortunately, however, the rig ended up with some problems.The composite traction belt, which had been inspected without any problems, suddenly broke before the loading was completed.The special one-and-a-half-ton tempered glass hit the steel carrier, shaking off a six-millimeter-thick tempered glass that hadn't had time to be fixed on the other side.Then this piece of toughened glass weighing about half a ton hit Wu Lian's leg directly, and cut his right leg into two perfectly.Thanks to the gap on the ground, the piece of tempered glass was stuck together with the body of the truck. Otherwise, the glass would continue to fall, and it would not be as simple as replanting a severed limb—maybe Wu Lian would be killed directly. Stoned to death.
