Ling Ran had never performed a tracheotomy on a human before, but he had done it on a dog.
In medical school, animal experiments were the main way for students to learn surgical techniques. Professor Yun Hua used dogs to perform tracheotomies.
Chestnut, the police dog lying on the operating table, was much luckier than its peers, but it also suffered more. Ling Ran patted its head. The two-year-old Chestnut only had the strength to look at Ling Ran, and it had difficulty breathing.
"Is there a suitable anesthetic?" Ling Ran asked the anesthesiologist beside him.
"All pets use Agent 846," the anesthesiologist said. "It's made by the Veterinary Research Institute of the Military Supply University. What the hell is it called … What is it called?"
"Hypnosis." An anesthesiologist who had a dog at home trotted over, patted the dog's head, and said, "Valium, dihydroetorphine, haloperidol, and the like. I'll do it. Can you do a checkup on the dog first? Give it oxygen …"
The dog anesthesiologist who came later ran to the medicine cabinet and searched.
"Okay," Ling Ran said. He picked up the stethoscope and listened to the dog's heart before he did a percussion. After that, he did a lung function test and counted the number of breaths. Although it was a physical examination for the dog, the method was the same as a human's. Ling Ran did not know if there was a special physical examination for dogs, but based on the current situation, it was good enough that it was useful.
"Fourteen breaths per minute." After Ling Ran finished listening to the breathing, he asked in confusion, "What should a dog's breathing rate be?"
A nurse searched Baidu and said, "Ten to thirty breaths?"
"Then, what does fourteen breaths count as?" Ling Ran continued to be confused.
Doctor Zhou, who walked over with his hands behind his back, suddenly felt like laughing and said, "Your question is more like an intern's."
The medical staff around them could not help but laugh.
The dog anesthesiologist ran back at this time. After he heard the number Ling Ran reported, he raised the needle in his hand and said, "I'll do the intramuscular injection."
As he spoke, he approached the Labrador, lowered his head to look at the wound, and injected the dog.
The police dog, Chestnut, twitched, but it no longer had the strength to struggle.
Soon, the police dog's limbs relaxed, and its breathing became lighter.
"Prepare the dog's skin. Lock the dog's limbs if you can." The dog anesthesiologist looked at his phone and began to instruct everyone.
The nurse looked at the big dog that weighed more than 30 pounds with a troubled expression. She repeated to herself, "Skin the dog?"
"Yes, prepare the skin for the dog and shave off the fur around its neck. Hurry up, I'm having trouble breathing, "the anesthesiologist urged.
"Have you worked as a pet doctor before?" Doctor Zhou asked the dog-owning anesthetist curiously.
"My friend did it." The dog-like anesthesiologist's expression was very serious. He took another look at his phone and looked at the image on it. It was obviously a live teaching session.
The hands of the young doctors and nurses who were working at the scene paused for a moment, but they soon started again.
What else could he do? It would be good to have someone to guide him.
In times of danger, everyone had to be guided to perform the surgery.
Most doctors did not care about a dog's life. As a doctor, who did not have a few dog's lives? However, police dogs were different, especially police dogs that had saved lives. Everyone was willing to work hard for half an hour.
"That's enough."
After the skinning was done, the dog had difficulty breathing.
Ling Ran carefully chose a scalpel and made a longitudinal incision along the exposed cervical vertebrae of the dog. He put down the scalpel and performed a blunt dissection on the muscle layer to expose the trachea.
Ling Ran made a horizontal incision on the trachea, accurately intubated the trachea, and connected the oxygen. Chestnut's breathing immediately improved.
Throughout the entire process, Ling Ran did not focus on speed.
Suffocation and suffocation were all very urgent, but as long as it was not so urgent that it caused complete suffocation, there was no need to perform an emergency tracheotomy.
Tracheotomy always had sequelae, and emergency tracheotomy was even worse. In comparison, as long as it was tolerable, the breathing difficulty could be alleviated.
Of course, it would be good as long as it did not take too long.
Doctor Zhou put his hands behind his back and looked at Ling Ran.
Although he looked like he had nothing to do, he was beside Ling Ran to prevent Ling Ran from making any mistakes.
Tracheotomy was a very minor surgery in the Emergency Department. Four layers of the larynx were cut open, and a small opening was made in the trachea between the two cervical vertebrae. The oxygen tube was inserted into the trachea. The damage was minimal, and the risk was not high.
However, if such a surgery was performed by medical interns, there would be people who would constantly make mistakes.
Just imagine the performance of ordinary students in handicraft classes during their studies, or the performance of some adults who assembled their own furniture at home, and you would be able to predict the occurrence of mistakes.
The models of handicraft classes and furniture were at least standardized. They were instruments of the same size, and there was a manual to follow. When they were designed, they were easy to install, but first-timers would still be very unfamiliar with it. It was no longer a joke for doctors who could perform heart surgery to not be able to install furniture from IKEA.
This showed the importance of repetition and experience.
It was fine to practice inserting needles on patients, but if things like tracheotomy or cardiopulmonary resuscitation were not done well, there would be irreversible mistakes. If medical interns or housemen wanted to learn how to do it, they would need to practice in private for a long time and find a suitable opportunity.
No one said much because Ling Ran was performing tracheotomy on the dog.
Even so, Doctor Zhou still had to show some concern by the side.
"Have you practiced before?" Doctor Zhou asked Ling Ran after the wound was treated.
"Not really. I just learned it. "Ling Ran's answer was a little strange, but it was true.
After confirming that the dog's life was saved, Ling Ran began to suture the dog.
As a police dog, Chestnut was wearing a stab-proof suit, so there were no external injuries on its chest and abdomen. However, there were many scratches on its limbs, and the dangerous area behind its ears was also cut open.
If such injuries were to fall on a human body, a CT scan or MRI scan would be necessary before surgery.
Dogs did not receive such good treatment. The doctors judged purely based on their experience. When they felt that the problem was not big, they gave the dog an antibiotic injection and Ling Ran performed a full suture.
For doctors, this kind of work was actually quite easy, but in their daily work, when it came to human lives, they could not do this even if the family asked them to do so.
With Master Level Appositional Suture, as long as the needle could be inserted, external injuries would be the easiest.
Ling Ran still used the technique of connecting thick threads with thin threads. He tried his best to help Chestnut keep its appearance beautiful, especially the parts with pores. He had to think carefully before he inserted the needle.
Even if it was a police dog, there was no harm in being beautiful.
"It's done." Ling Ran cut the thread and threw the scissors on the plate.
Even if he was suturing the dog, Ling Ran still had nurses beside him to help him. He did not have to worry about the follow-up bandaging.
The dog-owning anesthetist looked at the equipment with a smile and said, "It's done. The dog is saved, but … all of your things need to be cleaned. Alright, I'll leave first. "
All anesthetists belonged to the Department of Anesthesiology, but they had all witnessed Department Director Huo's ability to scold people. When the dog anesthetist saw that the police dog was fine, he turned around and left without any hesitation.
A nurse could not help but wail, "I'm going to be scolded to death by the head nurse."
"Let her take care of the dog later. Just don't deduct her salary." Doctor Zhou chuckled a few times. Then, he stroked the police dog whose eyes were closed. He took out his phone, took a selfie that was filled with love, and began to post it on his Circle of Friends.
The young nurse had no choice but to take a selfie with her cheeks puffed up and post it on her Circle of Friends.
Ling Ran turned around to wash his hands. After he was done, he realized that there was dog fur on his body, so he went to the Operating Area to take a shower and changed into a new pair of underwear. Then, he looked at the mirror with a relaxed body and said, "System, system, what's the ranking of my surgical skills?"
"Your pen-holding technique is currently ranked 766 in Yun Hua City, and the bow-holding technique is currently ranked 558 in Yun Hua City," the system answered.
Ling Ran furrowed his eyebrows. "What was the ranking when I asked last time?"
"Since the last time you asked, the ranking of the bow-holding technique in Yun Hua City has not changed, but the ranking of the pen-holding technique in Yun Hua City has dropped by one place."
"It's still dropping?"
"Yes."
Ling Ran chuckled a few times. That was true. His ranking would always rise, and there would always be people whose ranking would drop.
It was only because of the new underwear that Ling Ran did not get so angry that he wanted to take another shower.
He racked his brain, returned to the first floor, and naturally took out his phone. He had waited for three hours just now, and only a dog that needed a tracheotomy came. Ling Ran was not confident that he could wait for another person.
The first floor, however, was filled with jubilation.
When Ling Ran took a closer look, he saw that the police dog had woken up, and it was licking its hands and acting cute.
The light golden Labrador had a square head, and its black eyes were extremely lively. When it tilted its head and stuck out its tongue a little, it looked very interesting.
The policewoman, who had also undergone a minor surgery, lay beside it. Her snow-white skin was revealed under her hospital gown. She had an exquisite oval face, and no one knew if she had any makeup on. She had big breasts and a slender waist, and she looked very interesting.
The male doctors around them watched the policewoman, and the young nurse played with the dog. It was a situation where both men and women enjoyed the show.
The police dog, Chestnut, seemed to have smelled Ling Ran's scent. When Ling Ran got closer, it immediately raised its head and whimpered. The policewoman had no choice but to order it, "Chestnut, lie down."
The two-year-old Labrador police dog was more mature than most twenty-two-year-old humans. It whimpered a few times and stopped moving.
Ling Ran could not help but go forward and rub it a few times.
The policewoman stared at Ling Ran in a daze for a few seconds before she muttered to herself, "I thought I was hallucinating."
"It's possible for people to hallucinate after they suffer from external injuries," Ling Ran answered from a doctor's perspective.
The policewoman's face immediately turned red, and she said in a soft voice, "I … no … about that, my name is Qin Min. Thank you for saving my dog."
"You're welcome." Ling Ran flashed a smile that fit the patient's needs. This was a new skill he had learned.
The policewoman's face turned even redder.
