Fentanyl is a controlled drug and is the most tightly controlled drug in hospitals. The doctor who prescribes the prescription needs to use a red prescription slip, commonly known as a "red ticket".

Each red ticket has a unique number on it so that the hospital review department can track the flow of prescriptions and the use of medicines. Xu Yourong had only joined the treatment team for a few hours, and the red prescription number she held was still affiliated with the neurosurgery department - the red prescription that could be used in the emergency room had not yet reached her. Although he really wanted to relieve the pain of the patient as soon as possible, Xu Yourong couldn't help it.

Not to mention Sun Lien, he doesn't have the right to prescribe yet. But fortunately, he was clever enough, and after seeing Xu Yourong's embarrassed expression, Sun Lien turned his head and rushed out of the rescue room. grabbed Liu Tangchun, who was about to go back to the office, "Teacher Liu, hurry, prescribe five milligrams of fentanyl!"

Liu Tangchun was dragged back by Sun Lien's arm for the second time in a short period of time. Poor Director Liu is in his fifties, although he was a soldier when he was young, his health is not as good as thirty years ago. Sun Lien lost the weight of his hand in a hurry, and dragged Director Liu to his eyes.

In fact, it is okay to find doctors in other emergency departments for such a thing as opening a red list, and it is not necessary to kidnap Director Liu from the hall. It's just that Sun Lien still has some other ideas - he has carried out severe burn rescue treatment in accordance with the requirements of the textbook. But the fracture of the corpus callosum made him a little uneasy. Whether it was in the morning or after dinner, Sun Lien did not see this state in Zhao Weihong. Then there is only one possible inference, Zhao Weihong's corpus callosum rupture occurred after he was discharged from the hospital. It is counted from the time you are discharged from the hospital until you are taken to the ambulance again. In this hour, Zhao Weihong's corpus callosum, which had been functioning normally for 67 years, was severely damaged.

What Sun Lien is afraid of is that burns are just a bitter ploy, and callosum injuries are the real killer feature. He had to make Liu Tangchun realize as soon as possible that the patient had serious brain tissue damage. In case the burn is to cover up the damage to the corpus callosum......

Sun Lien has no hope in the humanity of Zhao Weihong's family at all.

Liu Tangchun quickly issued a red ticket. The male nurse intern, who had been waiting for a long time, took the red ticket and ran towards the pharmacy. The severe pain caused by the burn had a reverse effect on Zhao Weihong's body, and the intense pain stimulated her brain to continuously secrete dopamine. And after this dopamine enters the viscous blood, it directly stimulates her already overwhelmed heart to continue to beat rapidly. If the pain is not relieved as soon as possible, it is only a matter of time before this heart strikes completely.

If the heart strikes, Zhao Weihong will basically be equal to one dead person - with her current condition, it is absolutely impossible to have a heart transplant. Extensive burns mean that there will be a lot of waste in the circulatory system to be disposed of, and if the liver and kidneys cannot get enough blood supply during the over-restricted operation, they will also enter the ranks of strikes one by one.

This is the first hurdle of extensive burns – multi-organ failure.

Three minutes after Zhao Weihong was sent to the emergency room of the Fourth Central Hospital, doctors from the anesthesiology department finally arrived at the scene.

Maintaining the circulatory system is the specialty of anesthesiologists, and unlike cardiology and respiratory, which treat diseases, the main job of anesthesiology is maintenance rather than treatment. Therefore, in terms of treatment methods, the anesthesiology department is also much rougher. Except for a few doctors who like to say "Da Lang, drink the medicine......", the doctors in the anesthesiology department don't talk much more often. They need to monitor the patient's heartbeat, breathing, blood pressure, and sometimes even pay attention to the patient's urination

"Don't use morphine, just fentanyl, morphine is not strong enough to relieve pain. "It was an attending doctor from the anesthesiology department who came to help, and when he visited Lin Lan's surgery in the morning, Sun Lien had seen him on the side, although his entire face was covered by a mask and a surgical cap, but the pair of black plate-framed glasses with white horizontal stripes left a deep impression on Sun Lien.

"I opened a red order, a fentanyl, and I've already gone to get the medicine......" Before Sun Lien finished speaking, the door of the rescue room was pushed open by the intern male nurse. He held a small plastic basket containing a glass vial containing a clear and clear liquid.

"Open the ultrasound to guide me. The anesthesiologist wearing zebra glasses put on gloves, skillfully took out the tools in the central venous puncture suit, disinfected the right neck of Zhao Weihong, who was lying on his side, looked at the guidance on the B ultrasound, started from the direction of the head, and pierced the needle on the syringe in the direction of Zhao Weihong's neck.

It stands to reason that the patient needs to lie flat to perform deep jugular venous catheterization, but Zhao Weihong's carbonized outer layer of back skin directly made Zebra dispel this idea. Fentanyl is still in the preparation, let Zhao Weihong lie down now, just afraid that she will hurt herself to death. Brave anesthesiologists do not opt for the subclavian or femoral vein, which is easier to penetrate but is also riskier. Instead, the neck vein, which is best suited for large volumes, was still chosen.

The catheterization went very smoothly, less than half of the seven or eight centimeter-long needles were inserted, and the dark red blood instantly returned to the syringe, which also marked the successful opening of the rapid rehydration channel. The skin expander in the puncture kit comes in handy by inserting the guidewire through the access channel next to the needle, stopping at the position of the guidewire scale marker and withdrawing the needle.

The skin expander is a very hard hollow plastic tube, the guidewire passes through the hollow place, the plastic tube is close to the position where the needle is inserted, and then I see the zebra doctor press it down, and the front of the plastic tube is directly squeezed into the skin. Poke the already thick pinhole even thicker.

Sun Lien, who was watching deep jugular vein catheterization for the first time, was terrified, and sighed in his heart - if he had stayed in the hospital honestly and actively cooperated with the examination, why would Zhao Weihong suffer this hardship?

After removing the skin expander, Dr. Zebra took out the rest of the fluid tube from his suit, and after passing through the guidewire, he slowly followed the fluid tube in the direction of the neck vein, which looked a bit like a sewer worker was running the wire into the clogged pipe.

After going down for about a dozen centimeters, Dr. Zebra stopped with satisfaction. He slowly pulled out the guidewire, and after drawing a little blood out of the liquid placement tube with a syringe, he nodded, "That's it, let's start rehydration." With that, he put down the syringe and went to help the nurses who were still dispensing fentanyl — painkillers, which is part of the anesthesiologist's job.
