Li Nana took a deep breath, and her eyes sharpened.

Ready to start the first real cardiopulmonary recovery rescue in her life, according to the steps of the exercise, Nana took the lead in opening Lisi's airway, then pinched Lisi's nose, wrapped Lisi's mouth with her own mouth, and blew inside twice in a row.

Then the hands were stacked together, pressed on the midpoint of the two ** lines on her chest, and pressed hard, usually she was trained with a dummy, but she didn't think that the chest cavity of a real person was obviously much harder, and the depth of the pressure should reach more than four centimeters, and it should reach 100~120 times per minute.

Nana concentrated all her strength, and after pressing thirty times in twenty seconds,

Blowing was done again.

Chen Yang watched from the sidelines, not thinking that in less than a month, Li Nana had improved so much, this set of movements looked very skillful, and it seemed that she had trained a lot on weekdays.

However......

The reason why Nana practiced this set of movements so seriously was that she hoped that one day she could dedicate her first kiss to her master in this way, and she had imagined that if her master encountered all kinds of dangerous situations, if one day he drowned, suffered cardiac arrest, and suffered a huge impact, she could save him as soon as possible.

Fortunately, Chen Yang didn't know that she had this kind of thought, otherwise she wouldn't have been sent to study medicine if she was killed, and I heard that the brain circuits of medical students are relatively strange.

Angus stood aside, he was allowed to stand aside by his master, and the whole person looked very nervous, his eyes were staring at him, and he didn't even dare to blink his eyes.

After Nana was rescued for three minutes in a row.

Liz finally regained her breath on her own.

coughed lightly, and then opened his eyes suddenly, his pupils were full of horror, and his whole body twitched and trembled, for Chen Yang and them, it had been more than ten days since they hunted monsters, but for Lisi, who was put into the storage space, this thing was just like what had just happened, and her mind was still full of scenes in the monster's head.

"It's okay. Li Nana comforted.

"Take a deep breath. ”

After gasping for breath several times in a row, Lisi did as Nana did.

Seeing that she woke up, Nana smiled, this rescue was very smooth, many patients with cardiac arrest, after experiencing a long period of hypoxia, the brain will be irreversibly damaged, the light behavior is abnormal, the intelligence is obviously reduced, and the heavy is very likely to become a vegetative person, and even brain atrophy, brain death and other symptoms.

"Very well recovered. Nana laughed.

Angus half-knelt down excitedly.

Chen Yang saw that Li Nana's forehead was covered with sweat, her bangs were glued together, her chest was wavy, and she was panting, I don't know why, Chen Yang instinctively reached out and touched her head.

"Tired, take a break. ”

"Hmm. Nana nodded obediently, in fact, she didn't like the master to touch her head, these days, she has slowly known that this kind of head touching is a manifestation of fatherly love.

She already knew from T'Challa that Angus had proposed to Liz in the presence of his master, and that on this island they were already husband and wife in the true sense of the word...... At the thought of this, Nana's face flushed.

In a sense, she was indeed created by her master, but she didn't want to be touched, she didn't want to be treated as a daughter, when she thought of this, Nana frowned slightly, and immediately strangled this rebellious idea at the level of fantasy.

She felt that all she had to do was be obedient.

Chen Yang also asked Nana to rest for a while, because there was still a tough battle to be fought next, and Lisi's situation was not bad, but the situation of the crocodile lizard beast was not optimistic at all, and he could only hold the mentality of a dead horse as a live horse doctor.

After about three hours of rest.

Lisi's body was fine, Nana had regained her strength, half of the people were gathered, and Chen Yang took the crocodile lizard beast out of the storage space.

Although the crocodile lizard beast is as thin as skin and bones, and its body is also tied up with flowers, it is still a fierce beast after all, and the moment it sees everyone, its body resists violently, T'Challa and others hold guns and aim directly at its head, and the rest of the people hold spears and also aim at it.

In the event of an accident, it will be killed as soon as possible.

Lith, who had just recovered, saw part of the scene in its mind, and was forced to kill it because she was afraid that the crocodile lizard would resist violently, and offered to ask for help, she stood beside the crocodile lizard, and gently stroked its head with her right hand.

Under Lith's caressing, the crocodile lizard gradually quieted down, but its expression still looked very painful.

"Can it be saved?" asked Chen Yang.

After seeing those pus and maggot wounds, Nana instinctively became disgusted, but the next second suppressed it, during the period of studying medicine, she crossed the psychological barrier, and could watch restricted-level dissection videos while eating, and at this level, it was not as disgusting as she was.

"I'll try. Li Nana said.

Nana put on medical overalls, put on a hat and gloves, and took the lead in examining the wounds of pus and maggots on the crocodile lizard's body, there were more than ten such wounds, the largest wound was more than ten centimeters in diameter, and there were parasitic maggots inside.

She studied medicine.

In the past, when medical technology was not developed, some extreme doctors would use maggot therapy, because maggots will not eat the healthy tissue around the wound, but only attack the necrotic tissue part on the wound, which does not affect the surrounding normal tissue, and can promote the formation of granulation tissue.

In extremely harsh environments, it can better protect wounds, it can also enter deep wounds that are difficult to reach by surgery, they contain bactericidal salts in the excrement after devouring carrion, and there are antibiotics and substances that help to heal ulcer wounds such as improving the patient's immunity.

It stands to reason that the deep wound on the right hind leg of this giant beast is very likely to form anaerobic bacteria, but it is the appearance of maggots that saves its life.

After some observation.

Nana felt that these wounds were not the root cause of the beast's emaciation, and that there should be other fatal injuries, so Nana continued to examine it, and found that the beast had a large number of ulcers in its mouth, and there seemed to be two or three large thorns stuck above the esophagus.

The thorns looked slightly transparent, and very slender and sharp, not like the bones of land creatures, and the owner said that not long before she came to this world, there was a tsunami on the island, and a large number of sea creatures were washed up.

Nana can roughly judge that the real cause of this giant beast should be that it ate food that she doesn't eat often, was stuck by fish bones, and ate too much food that she is not suitable for, resulting in a series of syndromes.

But these can be solved, what really gives Nana a headache is that this giant beast is not only stuck with fish bones in its throat, judging from the blood in its stool, she thinks that the stomach of this head and abdomen is also likely to be scratched by fish bones, and there are stomach ulcers and bleeding symptoms, which is the most deadly.

Nana's medical studies are too short, even if there is a tutor teaching her, it is impossible to involve all the knowledge, and it is very lucky to be able to understand this.

Only a conservative treatment plan can be given to this giant beast.

Advanced trauma treatment, followed by anti-inflammatory drugs and antibiotics, cleaning the mouth ulcers, removing visible fish bones, as for the wounds and fish bones in the stomach, Nana has no choice but to suggest that it be allowed to eat liquid food recently, and wait for its own digestive juices to slowly digest the fish bones.

Once you've decided on these.

Nana took tweezers, a scalpel, hydrogen peroxide, and a simple pu-aspirator, ready to treat the wound, first pinching out the wriggling maggots, and then scraping off the carrion.

When shaving.

The giant beast grinned in pain, but under Lisi's reassurance, the giant beast had somewhat understood that these two-legged humans had no intention of killing it, and with every scalpel scraping the flesh, it looked pitiful and strong.

Chen Yang watched from the sidelines.

In just over an hour, Nana took out a total of three or four hundred maggots, and this was only two wounds, and there were nearly ten wounds of the same size.

Nana's forehead was covered with beads of sweat the size of beans, but her eyes were still engrossed in the wound, maintaining absolute concentration, Chen Yang couldn't help but pay tribute to those doctors who were struggling on the front line, they were really very hard.
