Is it possible that it is related to the microcirculation of the human body?
When the patient's blood pressure drops, the anesthetist will give vasopressors to stabilize the blood pressure, and many of the vasopressors will affect the microcirculation.

"The patient's blood pressure dropped just now, what kind of vasopressor did you give?" Qin Feng looked at the anesthesiologist.

"Ephedrine."

Ephedrine is the most commonly used vasopressor. It can stimulate the sympathetic nerves. Compared with adrenaline, ephedrine has a longer duration of action, and can also relax bronchial smooth muscle and constrict blood vessels. The central excitatory effect is also more obvious.

But ephedrine has a fatal side effect, which is its impact on the body's microcirculation.

Qin Feng thought for a while and said: "The patient's venous blood can't get in, I think it may be related to ephedrine."

"You mean, the patient's microcirculation is damaged?" The anesthetist also quickly responded.

Generally speaking, ephedrine has little effect on microcirculation, so you don’t need to worry about it. Anesthesiologists will ignore this minor problem.

However, the current patient is in a very poor condition, almost dying.

In addition, the operation lasted for a full seven hours, and the patient's body could be said to be like a candle swinging in the wind, which could be extinguished at any time.

Any unfavorable factors will be infinitely magnified in patients.

The laryngologist nodded in approval.

For the time being, it was not possible to confirm whether the microcirculation was damaged, so Qin Feng could only give it a try.

"Prepare warm salt water and gauze." Qin Feng instructed the equipment nurse.

Because the effect of ephedrine on the microcirculation comes from the sympathetic nerve excitation, the diameter of the surrounding blood vessels will also shrink according to the smooth muscle, thereby reducing it.

At this time, the large blood vessels may not be greatly affected, but for those small blood vessels in the microcirculation, the sympathetic nerve has a greater contraction effect on the arterioles than the venules, which will lead to a decrease in blood flow in the microcirculation.

After being enlarged in the patient's body, there will be a serious consequence, that is, the caliber of the arteriole is almost shrunk and sealed, resulting in the inability of blood flow to pass through, and there will be no blood flow out of the vein after the flap transplantation.

Qin Feng soaked the gauze with warm salt water and covered it on the surface of the transplanted skin flap. The principle of thermal expansion and contraction was used here.

Now that the blood vessels are closed, the local temperature is increased to allow the caliber of the blood vessels to expand again and restore blood flow.

Ephedrine has entered the patient's blood and cannot be extracted. The patient's body does not allow other drugs to offset the side effects of ephedrine.

What can be done now is to allow the patient's own circulatory system to offset the side effects of ephedrine, thereby restoring the microcirculation to normal.

Although this method is a bit unreliable, it is worth a try compared to doing the operation again.

The temperature of the gauze gradually cooled down, but blood flow still did not appear.

Qin Feng continued to change a piece of gauze and covered it again.

After changing five gauze in a row, just when Qin Feng was about to think about the cause of the disease in other directions, the patient's dry veins began to gush out red blood, from dots to raging rivers.

"Blood flow is restored!" The laryngologist exclaimed in surprise.

Li Xuewen also heaved a sigh of relief. He has been doing surgery with Qin Feng non-stop during this period of time. The friendship between the two is already super good, so Li Xuewen doesn't want Qin Feng to have regrets like this.

Qin Feng swayed a bit, and the laryngologist supported Qin Feng.

"Bring me a bag of glucose water." Qin Feng said weakly.

The instrument nurse cut the glucose solution and slowly poured it into Qin Feng's mouth at an angle. Qin Feng gradually regained a little strength.

Seven hours of long-term nervous tension is also a torment for Qin Feng,
In fact, many times, doctors rely solely on that force to hold on.

Qin Feng leaned against the corner to relax, then walked to the operating table again. Looking at the patient's restored veins, he relaxed.

Now it seems that there is no problem with his operation.

"Reinsert the drain and perform layered sutures."

Li Xuewen stepped forward to help Qin Feng with the finishing touches of the operation.

After 15 minutes, the operation was declared complete.

"Call the ICU and ask them to come pick you up." Qin Feng said.

Because the patient's condition is so poor, after the operation, he needs to be sent to the intensive care unit for observation for five to seven days.

Other departments do not have this assurance of monitoring.

Only the ICU has no infection, and it is an isolated environment. Once the patient has an infection, it is basically a dead end. Only the ICU is the best choice.

The operation started at noon, and after it was completed, it was completely dark outside.

Walking out of the operating room, Qin Feng took off his mask and took a deep breath.

After all, after staying in the stuffy operating room for a long time, when I came to the corridor, I felt that the air in the corridor was fresh.

"Doctor Qin."

The family members saw Qin Feng coming out and ran over quickly.

Qin Feng felt that his hand was being held by someone, and saw the patient's wife looking at him with moist eyes, hesitating to speak.

"Doctor Qin, was my dad's operation successful?"

The patient's son asked with a trembling voice.

"Very successful." Qin Feng smiled.

……

Back at the outpatient clinic, Qin Feng was called by Zhao Guoping to chat for a while.

"Xiao Qin, the patient's condition is so serious, why do you still insist on the operation?"

The doctors who consulted before all know that whoever undergoes this operation will suffer. The best way is to refuse and adopt conservative treatment.

Persisting in surgery not only may cause the patient to die on the operating table, but also poses a great risk of medical trouble.

What the hospital sees the most is that when the family members are alive, they seem to be very rational and talkative, but once there is a problem, it doesn’t matter whether it is the responsibility of the hospital or whether they signed a waiver, they just make trouble for no reason.

"If the patient believes in me, I can't give up on him."

The words are very simple, but it also shows Qin Feng's determination.

Since patients believe in me, why can't I believe in myself.

Zhao Guoping was silent. It seemed that at a certain time, what he cared about was not the postoperative effects, but the patient's trust.

This kind of trust has put his life in the hands of the doctor, so the doctor is naturally duty bound.

Zhao Guoping asked Qin Feng to leave work directly, and Qin Feng received a strange call on the way to get off work.

"Hello, hello."

"Doctor Qin, are you Doctor Qin?"

"I am, are you?"

"Doctor Qin, I am a patient you treated in Taoshi before. My name is Xu Dongqiang. You gave me the phone number, so I can call you if I have anything to do."

Qin Feng was a little confused. It had been almost half a year since he left Taoshi. There shouldn't be any problems. However, Qin Feng still asked patiently, "What kind of surgery did I perform on you? Are you feeling uncomfortable now?"

"It's not my problem. It's my wife who's sick and can't be admitted to the hospital now! I want to ask Doctor Qin for help, and see if I can find a doctor from Jiangcheng Hospital to accommodate me. Any hospital will do. I'm willing to pay as much as I want. Just give me a bed!"
