Ji Xiang went to the emergency room of the Second Affiliated Hospital as quickly as possible.

This time the system task was not as calm as before, but kept flashing like an alarm light.

Maybe this is the difference between emergency missions. Ji Xiang didn't think much, threw his bicycle aside, and ran into the hospital at a quick pace.

"Doctor Xiao Ji!" Colonel Wang waved and called Ji Xiang in a low voice.

"Teacher Wang." Ji Xiang ran over in the crowd, "What's going on?"

At this time, the hall of the emergency department was in chaos, and only the door of the emergency room was a little quieter.

Several people stood at the door with gloomy faces, and people kept reporting the situation to them.

Among the people who reported the situation, Ji Xiang only knew one - Dean Zhao.

Dean Zhao, who was like the moon among all the stars that day, is now like the most inconspicuous little star, unable to get close to him at all.

"Two died on the spot, and the others...explosion, fire, and burn victims have reached 16 people." Colonel Wang sighed, and his short and fat body seemed to have shrunk a little.

No one will be in a good mood when mentioning such a serious accident.

"Is it serious?" Ji Xiang asked nonsense.

"Several people with minor and moderate injuries were sent directly to the stage. Now there is a patient with severe burns who cannot establish an intravenous channel... People, it is probably very difficult."

Ji Xiang checked the system tasks and knew that this was the patient who was "waiting to die".

"I'll go take a look." Ji Xiang said.

"Don't go." Colonel Wang sighed, "It's worse than expected. Two have died, and one can't even get a needle in. I've tried both the anesthesiology department and the nursing department, but it doesn't work. I'm about to leave." .”

Ji Xiang was a little confused.

Seeing Ji Xiang's confused look, Colonel Wang knew that the rookie had no idea what it meant, so he explained, "Three people who died in a major safety accident need to be reported, and the city has ordered that the patients must be rescued."

"It's better not to save me at this time," Mr. Wu said in a low mood, with his head lowered.

Colonel Wang shook his head and said, "Keep your voice down."

Mr. Wu sighed. Ji Xiang didn't know what kind of things they had encountered before they would say such a thing.

But the gossip can be pushed back. The most important thing now is to leave an intravenous channel.

You can't just watch people die.

But Ji Xiang didn't even know the most basic situation. He asked cautiously, "Teacher Wang, what's the condition of the patient? Why can't even the needle be inserted?"

"The whole body is burned, even the soles of the feet are burned. Only a little blood vessel can be seen on the right side of the groin." Principal Wang said, "But there are rotten skin and blisters, just one blood vessel. Finally, Director Xu from the Department of Anesthesia Yes, try to leave an intravenous channel."

"Then what?"

"It failed." Colonel Wang sighed again, "The blood vessels of severely burned patients are extremely valuable. There was once a burn patient who lived in the sterile room of the burn department. When a doctor changed the dressing, the venous channel fell off for no reason. Well, that doctor was pointed in the nose and scolded by the director of the burn department for a week."

"..." Ji Xiang was speechless. A rookie like him couldn't understand how serious the situation that Colonel Wang said was.

"Let's take a look at the stage later. Sooner or later, you will have to rotate to the burn department." Colonel Wang said, "Let's see what the lighter patients are like first, so as not to be unable to bear it later."

There was a strong hint of support here, but Ji Xiang was a little anxious, so he didn't say anything and turned around and went to the bathroom.

"No manners at all." Mr. Wu looked at Ji Xiang's tall back and said with disdain.

"It came in such a hurry, coupled with the tension, the sphincter... even the gods couldn't bear to hold in the urine." Colonel Wang was very tolerant of Ji Xiang.

Ji Xiang found a quiet place and entered the system space with breathless concentration.

"Teacher, do you know the mission?" Ji Xiang asked anxiously after coming in.

Although the time flow rate in the system space is different from that outside, Ji Xiang, a rookie, has been unknowingly assimilated into the tense and depressing atmosphere and immersed in it.

"I know." The system NPC said slowly with his hands behind his back and his waist, "Go and see the simulator first, and then give your opinion on how to deal with it."

It turned out that it was ready, but Ji Xiang didn't show politeness to the system NPC and strode into the operating room.

A simulated man with burns all over his body was lying on the operating table. Ji Xiang took one look at it and felt ice-cold in his heart.

Burns all over the body turned out to be like this.

The carbonized parts of the simulator's body are covered in red patches and blisters, and the lighter parts are covered with red patches and blisters. There is no complete skin at all. No wonder it can't be penetrated by needles.

"Generally speaking, scalp acupuncture and indwelling needles in the groin are the most commonly used methods for establishing intravenous access for burn patients." The system NPC explained, "But this patient was seriously injured, and only the HY area was basically fine. However, there were also many blisters in the groin area.

, take a look."

Ji Xiang gradually felt helpless.

The system mission is correct. There is no way to leave an intravenous channel. Except for the palm-sized area of ​​the patient's lower body, there is no complete area at all.

"Teacher, how should we do this?" Jixiang asked in confusion.

"I'll teach you," the system NPC said calmly, "I showed you the anatomical structure of the corpus cavernosum on the first day, please tell me."

"There are a large number of cavernous sinuses behind the corpus cavernosum, which are equivalent to valves. After stimulation, the local smooth muscles relax and a large amount of blood is pumped in..."

Ji Xiang said, and suddenly understood the meaning of the system NPC.

But... puncture and infusion from the corpus cavernosum? Ji Xiang has never heard of this method.

"Teacher, do you mean infusion through the corpus cavernosum?" Ji Xiang asked tentatively, fearing that he had misunderstood.

"Yeah." The system NPC nodded.

Ji Xiang couldn't laugh or cry.

The corpus cavernosum is not a blood vessel!

But logically speaking, it seems... ok.

However, looking at the helpless expressions on Colonel Wang and Mr. Wu's faces outside, it is estimated that even veterans from the Department of Urology have never done anything similar.

"The basic principle is this, I operate it once and you watch." The system NPC put on sterile gloves and began to operate.

Simply prepare the surgical area and clean the remaining hair roots again.

The system NPC then begins to disinfect the skin around the stem.

Lift it with your index finger and thumb, fix the corpus cavernosum behind it, take the right side of the corpus cavernosum, and there is no subcutaneous vein area on the side.

"Be careful to avoid damaging the dorsal neurovascular bundle and ventral urethra."

The system NPC warned Ji Xiang when he accomplished this step.

Ji Xiang nodded. He understood the operation of the system NPC. It was not difficult, it was just a matter of thinking.

What he was curious about was whether it would work.

After all, Ji Xiang had never seen, heard of, or even thought about infusion through the corpus cavernosum.

The system NPC uses a No. 6 infusion needle to penetrate the corpus cavernosum about 2cm through the side at a 45° angle, and then inserts the needle about 0.5cm after breaking through the tunica albuginea.

"There is a saying about the needle of the infusion set. I won't go into details. You can feel it carefully later." The system NPC explained, "45° from the side is the best angle. Based on the patient's condition, insert the needle 2cm. When the needle pierces the tunica albuginea,

There will be a sense of disappointment.”

"Puncture the tunica albuginea by 0.5cm, and just stop when you feel a sense of loss."

The system NPC inserts the needle and opens the infusion channel.

The liquid is opened to the maximum and dripping in the dripping pot.

Ji Xiang's heart was beating wildly, so simple?!

The swollen liquid symbolizes vitality. If possible, the patient may have a chance!

Ji Xiang immediately helped the system NPC fix the needle with a dressing, and the system NPC adjusted the infusion speed to 50ml/min.

“It is difficult to replenish fluids after a large burn, which is a very confusing clinical issue.

Because the effective circulating blood volume drops sharply after extensive burns, immediate and rapid rehydration is the fundamental measure to rescue shock.

However, after large-scale burns, the skin is severely damaged, and the blood vessels on the body surface are severely damaged. There are not many veins for infusion, and there is even nowhere to penetrate. Even the remaining skin is a precious skin donor area and needs to be protected."

After the system NPC finished all this, he looked at Ji Xiang and said calmly.

Ji Xiang vaguely understood the consciousness of the system NPC by referring to the gloomy expressions of people outside the emergency room and the helpless expressions of Colonel Wang and Mr. Wu.

Indeed, it is difficult for doctors to accept that a living person is alive and dead without establishing intravenous channels.

"Deep vein puncture or incision requires skilled operating techniques from the operator and strict local sterile conditions. It is difficult and time-consuming. It cannot replenish a large amount of fluids in a short time, which affects the timing of rescue and the effectiveness of treatment."

"Teacher, is there any other way?"

"Medullary cavity puncture can be done." The system NPC said, "However, large-area burns are a contraindication to bone marrow cavity puncture, so it is not suitable at this time. If you do it reluctantly, subsequent infection, etc. will be a big problem."

"The corpus cavernosum has its own advantages. First of all, it is relatively hidden in location and difficult to burn. The skin is relatively intact, the anatomical position is relatively fixed, and it is easy to puncture.

The cavernous body is composed of many cavernous trabeculae and lacunae. The lacunae are actually sinus spaces that communicate with blood vessels. The blood sinus lacunae are large and extensive, and return to the deep dorsal veins of the vagina, enter the pelvic venous plexus, and directly enter the systemic circulation.

.

And another advantage is that the corpus cavernosum is surrounded by a tough albuginea, which keeps the blood sinus open even when the blood volume is insufficient. It is a relatively independent and complete tissue structure, making the puncture fast, accurate and successful.

high."

Ji Xiangmo Lake's understanding gradually became clearer with the explanation of the system NPC.
