The key to operating the balloon mask ventilation technology is to seal and open the airway.

If the ventilation is not satisfactory during single operation, double-person pressurized auxiliary ventilation should be considered, and the airway is opened with the technique, oropharyngeal or nasopharyngeal ventilation duct should be used simultaneously. This technique is mainly used when patients have the risk of aspiration and reflux, and the annular cartilage compression is given at the same time.

Even the laryngoscopy and light rod guidance technology have been used. The basic operation of a single balloon mask has been ruled out by Zheng Ren and will not be considered.

However, the double balloon mask ventilated with a small tidal volume and high frequency and high pressure to provide oxygen, and it was found that the patient's chest fluctuations were not obvious.

"Laughter mask!" Zheng Ren shouted in a deep voice.

At the same time, he had already put on sterile gloves and his eyes moved back and forth between the ECG monitoring and the patient, but he did not perform a tracheotomy as soon as possible.

The patient's current situation is a high-risk tracheotomy. Zheng Ren tried it in the system operating room. Even if he has the halo of luck, even if he has a reward bonus of +10 for the completion of the surgery, even if it is just a small operation, the final completion of the surgery is only 65%.

This means that the patient may not be able to go offline through a ventilator-assisted breathing, or even cannot go off the operating table at all.

Zheng Ren tried many times, and his success rate of 65% was already the highest.

In fact, it is not uncommon for patients with high-risk tracheostomy.

The main ones are short neck, obesity, sitting upright, unable to tilt the head, restlessness, wide or occupying space, high mediastinum, slant of the trachea, falling back the tongue, severe breathing difficulties, and people with oral intubation through oral trachea but without spontaneous breathing, poor coagulation function, sudden suffocation before surgery, unclear signs of cervical and chest bones and cartilage are all high-risk tracheotomy.

Generally, it can be compensated by means of techniques, but the patient in front of him is very special, so Zheng Ren was very helpless. This time he encountered something particularly difficult.

Fortunately, the mask has a good oxygen effect and has been tested in the system operating room.

An anesthesiologist quickly opened the throat mask and handed it to Zheng Ren.

After getting the purchase, Zheng Ren pulled the patient's jaw with his left hand and was about to send the throat mask in, but was surprised to see that it turned out to be a second-generation throat mask!

Strangely, the third generation of laryngeal mask is clearly used in the system operating room. What's going on?

There is a big difference between the second-generation and the third-generation explorer's throat mask. Even the third-generation throat mask is only 98% final, so Zheng Ren dared not be careless.

"Three generations of explorers!" Zheng Ren said immediately.

Director Xu was stunned for a moment, three generations of explorers...the throat mask?

The patient's blood oxygen saturation has dropped to 70%. Why is Boss Zheng still picky about the second and third generation throat masks...

He was about to explain, when Feng Xuhui stood outside the operating room and immediately said loudly, "Mr. Zheng, wait!"

He held his cell phone in his left hand and made a call, which almost instantly answered. Feng Xuhui said quickly: "Emergency rescue box!"

While talking, Feng Xuhui quickly came to the door of the operating room with "dang" steps.

Opening the door of the operating room, Liu Xiaojie, more than ten meters away, pushed the box over. The heavy trolley box slid on the marble floor, almost at the moment when Feng Xuhui opened the door.

It took 3.2 seconds to take the box and close the door.

Director Xu has been following Feng Xuhui, and he remains calm. After all, he is the director of the University of Anesthesiology and has seen too many similar situations.

But today's patient's condition is more special. If it were a normal laryngoscopy, it would have been done.

Boss Zheng has not done a tracheotomy for a long time, and Director Xu also knows that this is a high-risk patient. Once it is incised, it may face more trouble. This trouble does not all come from the patient's family, but more from the patient themselves.

It is not uncommon for the patient to have a worsening condition after high-risk tracheostomy, so he also prefers to use a laryngeal mask.

However, the 912 laryngeal mask is pretty good. The model has been used for many years. Boss Zheng actually wants 3 generations of explorers. This type of laryngeal mask has only been heard at academic conferences. The anesthesiology department of 912 has not yet evolved to this point.

The small consumables vendor who has been following Boss Zheng seems to be... the manager who intervened in the consumables manufacturer. What did he just shout about? First aid kit?!

After Director Xu saw a medium-sized trolley box "flying" in, the small consumables vendor immediately squatted on the ground and opened the box.

The trolley box is neatly placed with a wide variety of emergency consumables.

He didn't even look at it, and stretched his hand in, as if he knew dozens of consumables everywhere.

A sterile packaging bag was immediately caught by Feng Xuhui. Seeing Director Xu standing not far away and looking at him, Feng Xuhui threw the bag in his hand over.

"Director Xu!"

You don’t have to be polite when you are in emergency rescue, and you don’t have time to be polite. Every minute and every second are extremely precious.

Director Xu took over the sterile packaging, and his purpose was to be a 3-generation explorer's throat mask.

“…”

It's so fucking, Director Xu felt that his face was invisibly hot.

But before I could think about it, I turned around and ran away, tearing open the outer packaging of the throat mask while running.

Zheng Ren took the throat mask and used conventional blind detection method to insert it.

Pull the jaw with the left hand to widen the oral gap, hold the throat mask with the right hand, and the mask mouth is facing the patient's jaw, and place it downward along the midline of the tongue against the posterior pharyngeal wall until it cannot be pushed any further.

After inserting the laryngeal mask, positive pressure ventilation was applied. Zheng Ren observed that the degree of thoracic undulation returned to normal. He grabbed a stethoscope and the breathing sounds on both sides of the auscultation were symmetrical and clear, and there was no air leakage in the anterior cervical area.

Even though he had done more than 10 operations in the system operating room, even if he was covered by the halo of luck after he came out, Zheng Ren was still very careful to check whether there were any errors in the operation.

After removing the throat mask, Zheng Ren placed a gastric tube to exhaust gas through the throat mask to solve the problem of a large amount of gas swelling in the stomach, causing the diaphragm to rise and the lung capacity to decrease.

“Propofol 40mg!”

“Midazolam 2mg!”

“Dexamethasone 10mg!”

Zheng Ren looked at the patient's electrocardiogram monitoring and kept issuing medication instructions.

"Intravenous infusion of aminophyline 0.25g + 5% glucose 250ml!"

The patient's blood pressure fluctuates between 184-110mmhg/98-55mmhg, and the heart rate fluctuates between 60-98 times/min.

"Nitroglycerin 0.05mg, Uraldier 15mg." Zheng Ren said in a deep voice.

Seeing blood pressure, heart rate and blood oxygen saturation continued to rise, the air in the operating room eased a little.

Boss Zheng’s medical orders were perfectly executed without any doubts, even Director Xu.

If he wasn't there, Director Xu would have prepared a throat mask in the next step, but when Boss Zheng stood there, Director Xu felt relieved for no reason, rather than being snatched away from the emergency rescue position, which made him feel that his authority was challenged.
Chapter completed!
