Going back to medical school to make up for the shortcomings is only the first step. Medical school dissects dead bodies, while in the clinic you face living people, and you still need to do more cases to accumulate clinical experience.

This requires the doctor to be bold and careful. Female doctors are usually timid, which makes them generally inferior to male doctors in such operations. Female doctors who are brave enough to do this are definitely outstanding.

So don't be fooled by the fact that Teacher Xin smiles all the time and smiles so gently, because her real identity is a general under Director Li. At the age of more than 20, she dares to lead students to play bronchoscopy alone, which shows that her personality and skills should be outstanding among doctors of the same age.

"Come, put on your hat and clothes." Xin Yanjun said to the students generously.

The teacher and student put on disposable surgical gowns and caps and put on sterile gloves.

The patient lies in the treatment position, supine.

Before the operation, the nurse gave the patient a topical anesthetic to numb his throat, similar to that used during gastroscopy.

This patient has high blood pressure, so for safety reasons, we connected him to an ECG monitor and adjusted the blood pressure monitoring frequency to once every three minutes so that we can observe his condition.

As an assisting doctor, Xie Wanying needs to help the teacher to lubricate the body of the fiberoptic bronchoscope with sterile paraffin oil, so as to reduce the friction between the body of the scope and the patient's tracheal wall when entering the patient's airway.

...

...

Everything is ready.

Xin Yanjun lowered her head and talked to the patient to calm her down: "Sister, we'll do this test later. Please cooperate with me. When I tell you to inhale, you just inhale. Don't be nervous. It's just a little uncomfortable when the tube goes into your throat. Just bear with it. It won't take too long."

The patient nodded, but it was impossible for him to look as calm as the doctor.

The nurse then handed the doctor a bottle of medicine for drip.

"Yingying, take it and drop it into her larger nostril. It's chlorine anesthetic." Xin Yanjun said to the students.

The cooperative nurse hesitated for a moment, then reluctantly gave the medicine to Xie Wanying, and reminded her: "If you don't understand anything, remember to ask the teacher first."

She was afraid that this intern had never used a bronchoscopy and would not ask questions and would mess around. Once Xin Yanjun started the operation, she would not care about the students at all and would focus all her attention on the patients.

Bronchoscopy is an invasive procedure that can harm the human body if not properly performed. The complication rate is as high as 0.3%. The most common bleeding is occasional massive bleeding that can be fatal. Other complications include hypoxia and infection. Each complication is very troublesome.

Knowing the pros and cons of medical operations well, Xie Wanying certainly had no objection to the nurse's nagging and nodded.

Holding the medicine dropper bottle, Xie Wanying followed the teacher's instructions and first observed the patient's nasal cavity.

There are three ways for the fiberoptic bronchoscope to enter the airway: through the nasal cavity, through the oral cavity, and if the patient has a tracheotomy, the tracheotomy can be inserted through the cannula. Most doctors prefer the nasal cavity as the preferred route.

The reason is very simple. If the tube is passed through the mouth, it is easy to be disturbed by the patient's mouth and tongue. If it is passed through the nasal cavity, no matter how much the nose moves, there is nothing in the nose that can move a lot, so it is destined to be difficult to disturb the tube. For example, today's patient in bed 21 is intubated through the mouth and connected to the ventilator. The doctor will first insert the scope into the airway through the intubation tube in the mouth.

In a nutshell, take whichever path is easier.

Carefully compare the sizes of the patient's two nostrils to see which nostril is larger and does not block the tube from entering.
