"Open!"

The call has ended now.

And the surgery is also over.

Upon system detection, the cow's vital signs are improving.

[The host successfully opened the special treasure chest from the daily activation task, gaining one spin of the Medical Technology Skill Roulette.]

Zhang Lingchuan chose to open it, and the treasure chest immediately unlocked.

Accompanied by a flash of light.

A roulette-like object appeared before him.

[Detected host's current status as an Emergency Department intern in the real world, the Emergency Medical Technology Skill Roulette is activated.]

"Emergency Medical Technology Skill Roulette? What is this??"

Zhang Lingchuan frowned.

It seemed like he was seeing this kind of reward for the first time.

It seems that the items from the special treasure chest include not only restricted skills and directly rewarded ordinary skills but also other things.

That makes sense.

Since getting the system, it hasn't even been half a year yet.

He hadn't encountered that many special treasure chests.

So the range of items was limited, and incomplete data was reasonable.

Suddenly, Zhang Lingchuan noticed the roulette starting to spin.

It seemed to be densely packed with emergency medical skills, like Abdominal Hematoma Excision, Jejunostomy, Colostomy, Intestinal Volvulus Reduction, Tracheotomy, Pericardial Puncture, Cecostomy, Closed Abdominal Drainage Procedure, etc...

They seemed relatively simple Level 1 and 2 surgeries.

Within the existing medical system.

Surgery levels are divided into Level 1 to Level 4.

Level 4 is defined as high-risk surgery.

Surgeries with extreme technical difficulty and high risk, such as coronary artery bypass graft, organ transplants, brain tumor removal, must be performed by a chief physician or a highly experienced associate chief physician in a tertiary hospital or specialized center.

Level 3 is defined as higher-risk surgeries.

Technically complex and high-risk surgeries, such as partial gastrectomy, thyroid cancer radical surgery, require an associate chief physician or senior attending physician to perform, and the hospital must be equipped with intensive care resources.

Level 2 is defined as lower-risk surgeries.

The Emergency Department includes procedures like Intestinal Volvulus Reduction, Tracheotomy, Pericardial Puncture, Internal Fixation for Fractures, Appendectomy, etc.

Usually requiring the involvement of an attending physician or higher qualifications, though in practice, a resident physician may perform them, with an attending physician responsible for teaching, etc.

Level 1 surgeries are the simplest low-risk surgeries.

Such as removal of superficial lumps, simple suturing, or closed abdominal drainage procedures.

Resident physicians can perform these independently, and often interns can also operate.

Of course, this is for human medicine.

In practice, as a veterinarian, he had performed surgeries of all levels.

After all, when an animal dies, it's often just about meat, and medical accidents are rare.

Even if they do occur, it's mostly a matter of compensating a bit of money.

So, veterinarians tend to be very daring.

Zhang Lingchuan was curious about where the roulette would land and what skill he might acquire.

[Ding! Congratulations to the host for obtaining the Tracheotomy skill.]

[The rating for this task is Perfect Level, and the host's Tracheotomy skill is at Perfect Level.]

The roulette finally stopped.

The Perfect Level Tracheotomy skill appeared.

The next moment, the long-missed Skill Tree appeared again before him.

[System Skill Tree Space is opening.]

[Ordinary Skills]

[Wound Cleaning and Dressing Skill "Peak Level"], [Basic Surgical Techniques "Six Master-level Skills"], [Cardiopulmonary Resuscitation "Perfect Level" (Basic First Aid Skill)], [Bone Setting Skill "Perfect Level"], [Heimlich Abdominal Impact Method "Perfect Level" (Basic First Aid Skill)], [Heart Area Striking Skill "Perfect Level"].

[Surgical Skills (Emergency Department)]

[Tracheotomy "Perfect Level"]

[Restricted Skills]

[Super Sonic Ear (Type B)], [X-ray Eye (2D)], [ECG Finger].

The tips of the Skill Tree lit up one by one.

And in the middle area, a new surgical skill appeared with the words "Emergency Department" on it.

At this moment, the entire Skill Tree layout also changed.

The left side featured ordinary skills, the middle surgical skills, and the right side restricted skills.

[Tracheotomy: A basic surgical skill in the Emergency, General Surgery, and Intensive Care units, classified as a Level 2 surgery. Indications mainly include upper airway obstruction, prolonged mechanical ventilation requirement, loss of airway protection ability, head and neck surgery or injury, as well as certain respiratory failures. It is a crucial life-saving measure. The Perfect Level Tracheotomy skill includes an anesthetic effect that reduces patient pain by 90%, minimizes incision bleeding, and provides the optimal incision while avoiding sequelae like subcutaneous emphysema, pneumothorax, mediastinal emphysema, etc. It even surpasses the need for surgical tools.]

Much like a train arriving at a station, the Tracheotomy skill went from all green lights to Master Level and Peak Level, finally stopping at Perfect Level.

He clicked on the Tracheotomy skill description.

Most of the first part was part of his daily routine, which he knew about in the Emergency Department.

However, he hadn't practiced it.

Firstly, as a veterinarian, he would definitely perform tracheotomies but was unfamiliar with doing it on humans.

Secondly, at the time, his main tasks were consultations and suturing wounds due to his excellent skills, so they assigned him related jobs.

Finally, it involved following Teacher Fang and others on ward rounds, writing papers, and participating in the 1-5 cycle training.

So his understanding of the Tracheotomy skill was at the knowledge level without practical application on humans.
