Now in front of Sun Lien is a huge problem.

Chen Xiao's head clearly showed a hint of "compartment syndrome". Although the handwriting is not too deep, it has reached the point that in Sun Lien's opinion, surgery must be performed immediately to start decompression.

Compartment syndrome is a relatively rare progressive orthopedic condition. It is primarily a progressive lesion caused by increased pressure in the compartment of the periosteostice.

The fascial compartment of the human body is made up of tissues such as bones, interosseous membranes, muscle septums, and deep fascia. Under the constraints of the fascia, the muscles are maintained in a specific shape to facilitate contraction and function. Compartment syndrome, on the other hand, is the result of a lesion with increased pressure in this area.

When a hematoma or edema of the compartment contents due to fractures, blood vessel damage, and soft tissue injury, or when the limb is bandaged too tightly, the additional pressure can cause the arterioles that supply blood to the muscles to close. Ischemia causes muscle to die and dissolve, further increasing the pressure in the compartment fascia. This leads to a more severe increase in pressure.

Once caught in this vicious cycle of "ischemia-edema-ischemia", the patient can be considered to have compartment syndrome.

Because this symptom is especially likely to appear in the limbs, the vast majority of patients with arm and leg fractures will be asked by doctors to be hospitalized for observation after reduction, so that in case of such symptoms, doctors can intervene as soon as possible.

The key to treating compartment syndrome is early intervention. It is important to intervene and interrupt the vicious cycle of ischemia-edema-further ischemia before the patient's limb is trapped in this vicious cycle. Doctors can take measures such as limb cooling, mannitol injections, diuretic use, and incision to decompression.

If not intervened early, the consequences of compartment syndrome can be fatal. A large number of dead muscle cells release large amounts of potassium and other cellular wastes. Once these substances re-enter the circulatory system as the pressure in the compartment decreases, they can immediately induce arrhythmias, ventricular fibrillation, and cardiac arrest. With further ischemia, dead tissue can form gangrene, causing a wider and life-threatening infection.

At these two steps, in order to save the patient's life as much as possible, the only thing doctors can do is amputation.

This is also the reason why Sun Lien has been trying to keep the patient in the morning and let Chen Xiao take over the surgical reduction treatment immediately.

But...... A physician cannot completely overturn the decision of a minor patient's guardian. With his family clearly refusing to be treated at this hospital, Sun Lien could do nothing.

The moment he saw Chen Xiao, Sun Lien suddenly felt that a big stone in his heart had fallen to the ground.

He wasn't expecting Chen Xiao to have some compartment syndrome - Sun Lien's heart was not so evil. For a doctor, the most terrible thing is a fatal symptom that has not yet happened but has a high probability of occurring.

It's like sepsis in an infected patient, DIC in a trauma patient, respiratory failure in a respiratory medicine patient...... You know that these critically ill patients can fall into these dangerous symptoms at any time, but you don't know when they will occur. This feeling is at least what Sun Lien fears and fears the most.

"You sit down first. Sun Lien turned on the light in the room and motioned for Chen Xiao to find a place to sit down. Then I called the hospital office directly, "Hello, I'm Sun Lien of the emergency department." ”

"Dr. Sun. The hospital staff on the other end of the phone obviously knew who Sun Lien was, "What's the matter?"

"I have a patient here who needs emergency surgery. Sun Lien said very naturally on the phone, and did not show any degree of unnaturalness at all. "Minors, but their families cannot be contacted. ”

"Authorization is required, right? What's the problem?" Sun Lien's frequency of asking the hospital office for surgery authorization is definitely the highest in the entire four hospitals. In other hospitals, having one or two emergency surgery authorizations a year is already very frequent. And Sun Lien ...... He alone can ask for it three or four times a year.

In fact, it is not a big deal to request authorization for emergency surgery, especially since Sun Lien's authorization application fully meets the relevant requirements every time, and he has never caused any trouble. Therefore, the staff of the hospital office actually "trusted" Sun Lien.

"compartment syndrome, on the right arm. Sun Lien's answer here was very smooth, "Other relevant inspections are still being supplemented, in order to rush for time, please start the process first." ”

"Got it. The hospital office happily agreed to Sun Lien's request, and then hung up the phone.

And Sun Lien put down the phone and began to "confess" to the child in front of him.

"Do you remember your parents' phone number?" The question should still be asked, although he may get himself into trouble later, Sun Lien almost did not hesitate and decided to take a risk.

It's a big deal to be deducted from his salary or even fined, and he really doesn't care much about these things now.

How much is an arm or even a life worth for a 14-year-old boy? Sun Lien didn't know what the answer was to this question. But one thing is for sure – that must be higher than the hospital's fine cap.

"I ......don't remember," the little boy was a little embarrassed, "I usually write it down on my phone......" he took out his mobile phone with his still mobile left hand and flipped through it, "Uh...... It's not written in this phone. ”

Sun Lien was a little surprised, but this situation was not too good. He continued, "Is there any way to contact your parents or grandparents?

"None of them. Chen Xiao continued to shake his head, and he answered Sun Lien's question in a very sincere tone. "My parents don't use WeChat. And I don't know where they are now - they both had something to do tonight and went out at four o'clock in the afternoon. ”

That's obvious. Sun Lien is very sure that Chen Xiao's mother paid the fee on WeChat at that time - her payment slip is still on the table.

Sun Lien, who was going to make a good confession to Chen Xiao directly, didn't know what he should say for a while. And Chen Xiao whispered a little embarrassed, "I also asked my friends, and they said that if you want to bypass your parents' consent to authorize surgery, you can only do this......" He looked at Sun Lien and said seriously, "I am only fourteen years old, and I don't want to have no right hand for the rest of my life." ”

Sun Lien nodded, with this sentence, everything else will be easy to do. "You come with me. He stood up, used the triangular scarf prepared in the office to briefly fix Chen Xiao's arm, and then walked out with Chen Xiao. "You just answered a good one, and you have to answer the same way when people ask you - no problem, right?"

"Don't worry. Chen Xiao nodded, "Those words just now...... Actually, it's not that I'm lying. ”
